At the same time to ensure the safety and stability of the product in different environments, reduce maintenance costs. Excellent elasticity performance: unique elasticity design makes it flexible and expandable within a certain range, which can effectively cushion and absorb mechanical vibration, reduce wear and fatigue damage between the components, and improve the stability and durability of the connection; in the installation, it can better adapt to the size tolerance of the hole, even if there is a certain deviation in the hole diameter, it can be tightly fitted to ensure that the connection is firm, and reduce the equipment failures caused by looseness, which is suitable for applications that have high requirements on the precision and stability of the connection. It is suitable for precision machinery and small equipment with high requirements for connection accuracy and stability. Precise size specification: Provide a variety of specifications from M1.5 to M5 to meet the needs of different aperture diameters and fine parts connection, which can be accurately matched with a variety of small mechanical parts, electronic components, etc., to ensure that in the narrow space and precision structure to achieve accurate and reliable connection effect, improve the installation efficiency and the overall performance of the equipment, providing more choices for the user in the manufacture of small equipment, maintenance and DIY creation to meet the diverse application scenarios. Diversified application scenarios. Reliable fastening ability: After careful manufacturing, the spring pin can rely on its own elasticity to generate enough friction after inserting into the hole, firmly fixed in the hole, effectively preventing the relative displacement of the components to ensure a tight connection; even if it is subjected to a certain amount of tensile force, pressure or shear force, it can maintain a stable connection state, which is suitable for occasions that require high reliability of connection, such as watch strap connection, small engine component fixing, modelling, etc., to ensure the normal operation of the equipment and reduce the need to repair and repair the equipment. It is suitable for applications requiring high reliability of connection, such as watch strap connection, small engine parts fixing, model making, etc., to ensure the normal operation of the equipment and to reduce the security risks caused by loose connection.

3. Product use scene

DIY and handmade: in family DIY projects, such as making jewellery, small metal ornaments, model planes, etc., it can be used for connecting tiny parts, and its elasticity and ease of operation make it convenient for users to carry out fine assembly to meet the needs of creativity and individuality, so that DIY enthusiasts can easily realize their own design concepts and enjoy the fun of handmade; in handmade maintenance, it can be used for repairing daily items such as spectacle frames and small toys. In terms of manual maintenance, it can be used to repair glasses frames, small toys and other daily necessities, quickly solve the problems caused by loose parts, extend the service life of the items, and save the maintenance cost and time. Electronic equipment and precision instruments: widely used in electronic equipment, such as mobile phones, tablet PCs, cameras, etc., used to fix circuit boards, connecting tiny parts, the stability and elasticity of its stainless steel material can prevent the parts from falling off or poor contact due to vibration and collision of the equipment, to ensure the stability of the electronic signal transmission and the normal operation of the equipment; in the field of precision instruments, such as microscopes and medical testing equipment, used for In the field of precision instruments, such as microscopes, medical testing equipment, etc., it is used for the connection of key components to meet the instrument's high requirements for precision and stability, to ensure the accuracy of the measurement and detection results, and to enhance the reliability and service life of the instrument. Small machinery and equipment manufacturing: in the manufacture and maintenance of small engines (such as model engines, lawnmower engines, etc.), used for piston pin connection, valve mechanism fixed and other key parts, can withstand the stress and vibration generated by high-speed operation, to ensure efficient and stable operation of the engine; in the production of small machinery and equipment (such as power tools, small water pumps, etc.), used for the connection of gears, shafts and other components, to improve the transmission efficiency and reliability of equipment, and reduce the equipment In the production of small mechanical equipment (such as power tools, small water pumps, etc.), it is used to connect gears, shafts and other components to improve the transmission efficiency and reliability of the equipment, reduce the risk of equipment failure, and provide high-quality connection solutions for the small machinery manufacturing industry.

Installation steps: Align one end of the spring pin with the hole of the connected part, use appropriate tools (such as tweezers or a small punch) to gently put it into the hole, keep the spring pin vertical during operation, avoid skewing it, and ensure that it is uniformly forced into the hole. If the spring pin is tight, use a small punch with a hammer to gently tap, but pay attention to the intensity of control to prevent excessive force leading to deformation of the spring pin or damage to the connected parts. When the spring pin is fully inserted into the hole, its ends should be flush with or slightly below the surface of the connected part (according to the specific application requirements). After the installation is complete, inspect the spring pin connection to see if the spring pin is in place, if it fits tightly with the connected part, and if there are any signs of loosening. A preliminary test can be made by applying an appropriate external force (e.g., slight pulling or turning of the connected parts), but do not exceed the rated load capacity of the spring pins. Precautions for use: In the process of use, regularly check whether there are signs of loosening, deformation, corrosion and other signs of spring pin connection parts, especially after the equipment is subjected to vibration, temperature changes or long-term use, such as found that the problem should be taken in time to repair or replacement measures to ensure that the connection is safe and reliable. For electronic equipment and precision instruments in the spring pin connection, it is recommended that regular professional maintenance and inspection, such as cleaning the connection parts, testing the elasticity of performance, etc., to ensure the normal operation of the equipment and stable performance. Avoid spring pins to withstand loads exceeding their rated carrying capacity, in the design and use of the process, should be based on the actual working conditions of reasonable selection of spring pin specifications, to ensure that it can withstand the external forces applied, to prevent overloading of the spring pin damage caused by the failure of the connected parts, triggering safety accidents. At the same time, attention should be paid to avoid the use of spring pins in harsh environmental conditions (such as high temperature, high humidity, strong acid and alkali, etc.), if necessary, protective measures should be taken (such as the use of high temperature, corrosion-resistant materials, protection of the connection part of the treatment, etc.), so as not to affect its performance and life. When storing and handling spring pins, avoid collision, extrusion or friction with hard objects to prevent surface scratches, deformation or damage, affecting the appearance and performance. Store the spring pins in a dry, ventilated, non-corrosive gas environment and keep them in a proper place, categorise them according to specifications to make them easy to locate and use, avoiding installation errors due to confusion of specifications, which may affect the use effect and safety.
