When the screw is positioned in two steps and the positioning is completed, the second electric push rod 302 is started, then the second electric push rod 302 pushes the motor 303 to move towards the direction of the positioning ring 404, so that the flat rod 305 moves and is inserted into the linear groove of the screw nut, then the motor 303 is started, so that the rotating shaft 304 rotates and drives the flat rod 305 to rotate, so that the screw rotates while moving to the left, and the operation of screwing the screw is realized, and because the feeding distance of the screw after screwing depends on the number of rotation circles of the screw, the transverse feeding distance is not necessarily the same as the feeding distance of the second electric push rod 302, and at the moment, the second spring 306 is stretched or compressed to adapt to the change.

Elasticity control assembly 5 is including being located the inside three equidistant evenly distributed's of tight space 7 inner wall control space 502, rotate between the inner wall of control space 502 be connected with the swing sensor 501 that annular electromagnet 601 corresponds, swing sensor 501 can control opening and close of annular electromagnet 601, keeping away from of control space 502 be equipped with spring space 504 in the lateral wall of tight space 7, sliding connection has in spring space 504 can with the stripper bar 503 of swing sensor 501 butt, stripper bar 503 with fixedly connected with third spring 505 between the inner wall of spring space 504. When the motor 303 starts moving to the left, the swing sensor 501 swings to the right, at this time, the annular electromagnet 601 is not started, the pressing block 604 clamps the screw, after the motor 303 moves to the left, the motor 303 drives the swing sensor 501 to deflect to the left, when the rightmost swing sensor 501 deflects to the left, the rightmost annular electromagnet 601 is started, the annular electromagnet 601 adsorbs the rightmost pressing block 604, the rightmost pressing blocks 604 are separated from each other and loosen the screw under the suction force of the annular electromagnet 601, the first step of loosening of the pressing block 604 and propelling of the screw is realized, and as the motor 303 continues to advance, the pressing blocks 604 of the second group and the third group are opened sequentially through the second swing sensor 501 and the third swing sensor 501, and after all the three groups of pressing blocks 604 are opened, the screw is firmly nailed into the nailing surface, subsequent screwing operation does not need to be positioned, then the complete screwing operation of the screw can be completed along with the continuous advance of the motor 303, and meanwhile, the extrusion action of the motor 303 on the swing sensor 501 is as follows: the swing sensor 501 is firstly completely squeezed into the control space 502, and at this time, the swing sensor 501 also pushes the left pressing rod 503 upwards, and after the motor 303 moves through the control space 502, the left pressing rod 503 pushes the swing sensor 501 out of the control space 502 under the elastic force of the third spring 505, so as to push the swing sensor 501 to the rightmost side again when the motor 303 returns, and the action principle of the swing sensor 501 at the rightmost side is the same as that described above.
