An electric push rod 24 is disposed at the lower end of the second sliding block 22 , and a support frame 25 is disposed at the output end of the electric push rod 24 . By turning on the switch of the electric push rod 24 , the electric push rod 24 can push the nut tightening head 44 at the lower end to move downward.

A third motor 3 is provided on the side wall of the support frame 25, and a third screw rod 31 is provided at the output end of the third motor 3. A third slider 32 is threadedly connected to the third screw rod 31. By turning on the power switch of the third motor 3, the third screw rod 31 at the output end of the third motor 3 can start to rotate through the bearing, and the rotation of the third screw rod 31 can drive the third slider 32 threadedly connected thereto to start moving on the third screw rod 31.

The third slider 32 is provided with a rack plate 34 at the lower end, and the rack plate 34 is meshed with a semicircular gear ring 35 below. When the third slider 32 starts to move, it can drive the rack plate 34 at the lower end to move synchronously. The forward and backward movement of the rack plate 34 can drive the semicircular gear ring 35 meshed with the lower end to rotate.

In the above scheme, a first slide bar 15 is fixedly provided inside the column 11, and the first slide bar 15 is slidably connected to the first slider 14. The setting of the first slide bar 15 can play a limiting and guiding role in the rotation of the first slider 14, thereby ensuring the stability of the first slider 14 moving on the first screw rod 13.
