A transmission cylinder 33 is provided on the inner side of the rotating sleeve 32. A first friction pad 34 is installed between the rotating sleeve 32 and the transmission cylinder 33. Third rolling bearings 35 are installed at both ends of the rotating sleeve 32. The lower end of the third rolling bearing 35 is installed on the workbench 1, and one end of the transmission cylinder 33 is connected to the nut sleeve 5, and the nut sleeve 5 is connected to the transmission cylinder 33. The light rod 6 passes through the inner side of the transmission cylinder 33, and a second friction pad 36 is installed between the light rod 6 and the transmission cylinder 33. An intercepting rod 37 is installed on one side of the upper end of the workbench 1, and the intercepting rod 37 is located at the rear side of the light rod 6; The process of driving the square frame 13 to move and the nut sleeve 5 to rotate by the driving frame 7 is as follows: the servo motor 18 is started to rotate, and the servo motor 18 can drive the rotating shaft 19 to rotate through the coupling. When the servo motor 18 reverses to drive the rotating shaft 19 to rotate, the first bevel gear 21 can be driven to rotate, and the first bevel gear 21 and the second bevel gear 22 are meshed, so that the second bevel gear 22, the first one-way bearing 23, the transmission shaft 24, and the first gear 26 can be rotated. If the servo motor 18 rotates forward to drive the rotating shaft 19 to rotate, the first bevel gear 21 can be driven to rotate, and the first bevel gear 21 and the second bevel gear 22 are meshed, so that the second bevel gear 22 and the first one-way bearing 23 can rotate outside the transmission shaft 24, and the transmission shaft 24 will not rotate.

If not, after the nut sleeve 5 is rotated to a position that fits with the nut, the nut can enter the nut sleeve 5, and then when the nut sleeve 5 is rotated When the nut is screwed onto the outside of the anchor bolt, it can drive the nut to rotate, and then the nut can be screwed onto the outside of the anchor bolt. If the anchor bolt and the nut are qualified, the nut can be screwed onto the anchor bolt smoothly. If the anchor bolt or the nut is unqualified, the nut cannot be screwed on the anchor bolt after being screwed on a certain distance. When the rotating sleeve 32 rotates, the friction between the rotating sleeve 32 and the transmission cylinder 33 can be overcome, so that the rotating sleeve 32 rotates, but the transmission cylinder 33 does not rotate. After the screwing is completed, the servo motor 18 is started to reverse, and the first gear 26 can be rotated through the transmission of the gear. When the tooth part on the first gear 26 contacts the first movable rack 27, the square frame 13 can be pushed backward, and the nut sleeve 5 can be moved away from the position of the anchor bolt. When the nut sleeve 5 moves backward, the light rod 6 can be driven to move backward.When the polished rod 6 moves to the intercepting rod 37, the polished rod 6 cannot move, but the nut sleeve 5 continues to move, so that the polished rod 6 can move to the outside of the nut sleeve 5, and then the anchor bolt can fall by rotating the rotating frame 2.
