[0041] Next, when it is necessary to process the pin shoulder of the fixed pin body 18, first start the motor 8. The motor 8 drives the bidirectional screw 9 to rotate, and the bidirectional screw 9 drives the two sleeves 10 to move relative to each other. The sleeve 10 drives the movable rod 11 to rotate. The rotation of the movable rod 11 causes the limit box 3 to move upward, and the limit bar and the slide groove are used to limit the movement of the limit box 3. By moving the limit box 3, the pin shoulder of the fixed pin body 18 is moved to a position suitable for processing by the processing device, and the pin shoulder of the fixed pin can be processed.
