Pins are common parts used in mechanical engineering for positioning, linking, and preventing loosening. Quick-release pins are one of them, with various material specifications, including stainless steel and high-strength alloy steel, and a wide range of applications, especially in the aviation field, where quick-release pins are used for quick disassembly, locking, adjustment and fixing conditions, and can be quickly and easily loosened to facilitate frequent and repeated connections.
Ordinary quick release pins, with a through hole in the pin sleeve and 2 steel balls in the hole, sometimes have unreliable positioning gram connection phenomenon. New 4 steel ball quick release pins can be used.
