Further, as shown in fig. 2, the first clamping jaw 121 may be provided with a first guide post 1211, the second clamping jaw 122 may be provided with a second guide post 1221, and accordingly, the slider 124 may be provided with a first guide hole 1241 and a second guide hole 1242, with the first guide post 1211 being movably disposed in the first guide hole 1241 and the second guide post 1221 being movably disposed in the second guide hole 1242. With this arrangement, when the slider 124 moves in the first direction relative to the first base 125, the first guide post 1211 and the first guide hole 1241 cooperate to drive the first clamping jaw 121 to move in the second direction, and the second guide post 1221 and the second guide hole 1242 cooperate to drive the second clamping jaw 122 to move in the second direction, so that the first clamping jaw 121 and the second clamping jaw 122 move in opposite directions or move in opposite directions, thereby carrying or releasing the screw 400.

Illustratively, the first guide hole 1241 extends in a first direction and is inclined to a second direction, and the second guide hole 1242 extends in the first direction and is inclined to a direction opposite to the second direction, such that the first guide hole 1241 and the second guide hole 1242 are symmetrically disposed in the second direction, so that synchronous opposite movement or synchronous opposite movement of the first jaw 121 and the second jaw 122 can be achieved when the slider 124 moves.

In other embodiments, the transfer portion 120 may include a first linear driving member 123 and a first base 125, where the first linear driving member 123 may include a first driving end and a second driving end that are respectively movable in a second direction, the transfer portion 120 may further include a first clamping jaw 121 and a second clamping jaw 122, the first clamping jaw 121 and the second clamping jaw 122 are respectively slidably connected to the first base 125 in the second direction, and the first clamping jaw 121 is connected to the first driving end, and the second clamping jaw 122 is connected to the second driving end. Through the arrangement, the first driving end drives the first clamping jaw 121 to move, and the second driving end drives the second clamping jaw 122 to move, so that the first clamping jaw 121 and the second clamping jaw 122 can move in opposite directions or in opposite directions in the second direction, and the bearing or releasing of the screw 400 can be realized.

The first linear drive 123 may be, for example, a jaw cylinder, although other forms are possible and are not specifically limited herein.

With continued reference to fig. 2, to effect the bearing of the screw 400, one end of the first jaw 121 may be provided with a first recess 1212 and a second recess 1213 in communication, and correspondingly, one end of the second jaw 122 may be provided with a third recess 1222 and a fourth recess 1223 in communication, such that, with the first jaw 121 and the second jaw 122 in a clamped state, the first recess 1212 and the third recess 1222 snap into each other, forming a clearance space for passing through the shaft section of the screw 400, and the second recess 1213 and the fourth recess 1223 snap into each other, forming a receiving space for receiving the cap end of the screw 400.

It should be noted that, when the first clamping jaw 121 and the second clamping jaw 122 are in the clamping state, they are mutually abutted, so that the first groove 1212 and the third groove 1222 are mutually buckled, and the rod section of the screw 400 can be buckled between the first groove 1212 and the third groove 1222, and at the same time, the end of the rod section can be protruded, so that the rod section of the screw 400 can be inserted into the guide hole 710; at the same time, the second groove 1213 and the fourth groove 1223 are fastened to each other, so that the cap end of the screw 400 can be fastened between the second groove 1213 and the fourth groove 1223. In addition, the cross-sectional area of the space is smaller than that of the receiving space, so that the screw 400 is prevented from slipping off, and the screw 400 can be smoothly transferred to the guide hole 710.

When the screw 400 needs to be released to enable the rod section of the screw 400 to enter the guide hole 710, the first clamping jaw 121 and the second clamping jaw 122 move away from each other, at this time, the first groove 1212 and the third groove 1222 are far away from each other, and when the cross section of the clearance space between the first groove 1212 and the third groove 1222 is larger than that of the cap end of the screw 400, the cap end can pass through the clearance space, so that the whole screw 400 can slide into the guide hole 710 positioned below, and the guide hole 710 can guide and limit the screw 400 conveniently.

In some embodiments, when the first clamping jaw 121 and the second clamping jaw 122 clamp, the first groove 1212 and the third groove 1222, the second groove 1213 and the fourth groove 1223 respectively hug the screw 400 from the sides, so as to prevent the screw 400 from being randomly moved during the transferring process, and thus the screw 400 cannot be accurately placed into the guide hole 710.
