[0002] Pins are a type of standardized fastener that can be used for static fixed connections or for relative movement with the connected parts. They are mainly used at the hinges of two parts to form hinge connections.

[0003] Publication No. CN219620341U discloses an automatic feeding structure for pin production. The patent can move the pin to the guide plate through the top plate, and then slide it to the placement groove, so as to facilitate feeding. When the diameter of the pin is large, the first movable plate can be moved backward, and then the second movable plate can be squeezed and limited by the threaded rod, so that the first movable plate can be limited, so that it can adapt to pins of different diameters, making it convenient to use, and a groove sufficient for the first movable plate to move is reserved on the storage plate. However, the patent still has the following problems in actual use:

[0004] The pin can be moved to the guide plate through the top plate and then slide into the placement groove, so as to facilitate loading. However, in actual use, the position of the first movable plate is adjusted when loading a pin with a larger diameter. After the first movable plate and the top plate lift the pin, the subsequent pin will move and fit the top plate.
