After tightening, the welding work can be started. When the angle of the workpiece needs to be rotated, the staff needs to drive the meshing block 82 in the meshing component 8 to move. When the meshing block 82 moves, it will drive the rotating disk 71 to move through the top turntable 83. During the movement, the tooth groove 74 on the side wall of the rotating disk 71 is meshed and connected with the driving gear 53 on the support plate 5.

When in contact, the engagement block 82 continues to move, and when moving, the snap-fit ​​block 94 will be squeezed into the snap-fit ​​box 9, and the snap-fit ​​spring 93 will be squeezed at the same time. When the rotating disk 71 is connected, the snap-fit ​​block 94 is ejected into the snap-fit ​​groove 84 opened on the side wall of the engagement block 82 through the snap-fit ​​spring 93 to ensure that the engagement block 82 is in a stable state. When the rotating disk 71 rotates, the engaging block 82 below remains in a fixed state, and when the clamping block 94 is clamped into the clamping groove 84, the driving gear 53 is also engaged with the tooth groove 74 on the inside of the rotating disk 71, and the rotating disk 71 can be driven to rotate. When the welding work is completed, when it is necessary to disengage the engaging block 82 and the clamping block 94, the staff can pull the pull rod 92 to pull the clamping block 94 back into the clamping box 9, and then the staff drives the rotating disk 71 to move to disengage the engaging block 82.
