tightening rod lifting driving shaft 42 and the rope tightening driving wheel 46 to rotate, thereby winding up the lifter pull cord 87 and the cushion drop panel return pull cord 111, and when the lifter pull cord 87 pulls the nut knob lever 12 upward, when the nut clamping cavity 16 is separated from the bolt, the mechanism moves under the action of the mechanism moving rotating friction wheel 26 again, when the bolt is loosened through the rear bolt stop pull cord 108, the bolt stop 21 is reset, during which, when the nut clamping cavity 16 is clear of the nut 19, the upper clamping control boss 94 is again clear of the clamping control block 96, causing the nut knob stem 12 to once again overlap and continue moving upwardly, again pressing upwardly on the nut carrier plate 71, the nut carrier torsion spring 106 again being compressed and then returning to its original position, until the upper elevator block 92 is once again captured by the elevator block movement stop 89.

3, in the process of forward movement of the cushion block falling plate 69, the right end surface of the cushion block falling plate 69 rubs with the part replacing power friction wheel 81 to enable the part replacing power friction wheel 81 to rotate, so that the ratchet power shaft 80 is driven to rotate 83, the part replacing power shaft 72 is driven to rotate 83 through the part replacing power transmission belt 85, the part supplementing mechanism 51 is driven to move 83 and the part replacing power shaft 72 to rotate, the part replacing friction wheel 73 drives the part push plate 49 on the part replacing belt 82 to move one grid, the nut 19 in the cavity 17 of the nut cavity is pushed onto the nut bearing plate 71, and meanwhile, the pressing block in the part push plate groove 50 is also pushed onto the cushion block falling plate 69.

4: the elevating drive motor 43 is reversed at the next operation, and the rotation direction at each operation is reversed from the previous one.
