The inner wall of the sliding rod sleeve has a second anti-rotation plane. The two anti-rotation planes fit together.
One part of the slide bar and the slide bar sleeve is provided with a guide rib along the axial direction of the slide bar, and the other part is provided with a guide groove along the axial direction of the slide bar, and the guide rib is inserted into the guide groove. Through the cooperation of the guide rib and the guide groove, the positioning between the sliding rod and the nail seat cover is accurate, that is, the positioning of the nail seat cover and the nail seat is accurate, thereby ensuring that the staple is correctly formed.
