When the nail bin assembly 2 is abutted with the adapting assembly 1, the push rod 23 is abutted with the first guide part 131, the protrusion 27 is positioned at one end of the first groove body 261 close to the working head, at the moment, the distance between the push rod 23 and the firing plate 22 is larger, and the first abutting part 242 abuts against the second abutting part 221 to prevent the firing plate 22 from being accidentally impacted by the firing rod 12 and moving. When the staple cartridge assembly 2 is rotated to move the push rod 23 from the first guide portion 131 to the second guide portion 132, that is, the push rod 23 moves from the initial abutting position a to the working position a', the protrusion 27 moves from the first groove 261 to the end of the second groove 262 far away from the working head through the transition groove 263, at this time, the distance between the push rod 23 and the firing plate 22 is reduced, and the first abutting portion 242 and the second abutting portion 221 are gradually separated to release the firing plate 22 due to the reduction of the rotational acting force and the distance.
Referring to fig. 14 to 21, indeed, in other embodiments, the locking portion 241 is provided with a sliding slot 26, the push rod 23 is provided with a protrusion 27, and the protrusion 27 slides from the second groove 262 to the first groove 261 to move from the first position B to the second position B'. When the nail bin assembly 2 is butted with the adapting assembly 1, the push rod 23 is in the initial butting position a, the push rod 23 is butted with the first guide part 131, the protrusion 27 is positioned at one end of the second groove body 262 far away from the working head, at the moment, the distance between the push rod 23 and the firing plate 22 is larger, and the first abutting part 242 and the second abutting part 221 abut against each other to prevent the firing plate 22 from being accidentally impacted by the firing rod 12 and moving. When the staple cartridge assembly 2 is rotated to move the push rod 23 from the first guiding portion 131 to the second guiding portion 132, that is, the push rod 23 moves from the initial abutting position a to the working position a', the protrusion moves from the second groove 262 to the end of the first groove 261 close to the working head through the transition groove 263, at this time, the distance between the push rod 23 and the firing plate 22 is reduced, and the first abutting portion 242 and the second abutting portion 221 are gradually separated from each other due to the reduction of the rotating force and distance, so that the firing plate 22 is released.
In summary, the following steps: by setting the locking mechanism 24, the locking mechanism 24 is connected with the push rod 23, when the push rod 23 is at the initial butt joint position a, the locking mechanism 24 locks the firing plate 22 so that the firing plate 22 cannot move axially, and the firing plate 22 cannot be pushed to deform even if the firing rod 12 is not successfully butted with the firing plate 22 in the butt joint process of the firing rod 12 and the firing plate 22; when the push rod 23 moves from the initial butt joint position A to the working position A', the locking mechanism 24 is driven by the push rod 23 to be separated from the firing plate 22, and the operation is fast and convenient.
