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 of its stainless steel material and the precise size can prevent 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 the connection of key components, to meet the needs of 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 testing 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 connecting the gears, shafts and other components to improve the transmission efficiency and reliability of equipment, reduce equipment and 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.

4. Product use instructionsInstallation steps: Align one end of the cylindrical pin with the hole of the connected part, use appropriate tools (such as tweezers or a small punch) to gently place it into the hole, keep the pin vertical during operation, avoid skewing it, and ensure that it is uniformly forced into the hole. If the pin is tight, you can 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 pin or damage to the connected parts. When the pin is fully inserted into the hole, both 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 pin connection to see if the pin is installed in place, if it fits tightly with the connected part, and if there are any signs of loosening. A preliminary test can be carried out by applying an appropriate external force (e.g. slight pulling, turning the connected part), but do not exceed the rated load capacity of the pin. Precautions for use: In the process of use, regularly check whether there are signs of loosening, deformation, corrosion and other signs of the cylindrical 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 a timely manner to repair or replacement measures to ensure that the connection is safe and reliable. For electronic equipment and precision instruments in the cylindrical pin connection, it is recommended that regular professional maintenance checks, such as cleaning the connection parts, testing the dimensional accuracy, etc., to ensure the normal operation of the equipment and stable performance. Avoid the cylindrical pin to withstand more than its rated load-bearing capacity, in the design and use of the process, should be based on the actual working conditions of a reasonable selection of cylindrical pin specifications, to ensure that it can withstand the external force applied, to prevent overloading of the pin to prevent damage to the pin, the failure of the connected parts, triggering a safety accident. At the same time, attention should be paid to avoid the use of cylindrical 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 cylindrical pins, avoid collision, extrusion or friction with hard objects to prevent surface scratches, deformation or damage, affecting the appearance and performance. Store the cylindrical pins in a dry, ventilated, non-corrosive gas environment and keep them in a proper place, and classify them according to specifications to make them easy to find and use, avoiding installation errors due to confusing specifications, which will affect the use effect and safety.
