The one end that the drive shaft was kept away from to the initiative worm wheel links to each other with main drive mechanism, and the one end that the frame was kept away from to the driven worm wheel links to each other with following drive mechanism, and on the frame was worn to locate by the both ends of drive worm, initiative worm wheel, driven worm wheel were connected with drive worm transmission respectively. The driving motor drives the driving shaft to move, the driving shaft drives the main transmission mechanism to move through the driving worm wheel, and drives the driven worm wheel to move under the transmission action of the driving worm, and at the moment, the driven worm wheel does not act on the driven transmission mechanism; when the main transmission mechanism breaks down, the main transmission mechanism is separated from the driving worm wheel and changes from driving to driven, the driven worm wheel acts on the driven transmission mechanism and changes from driven to driving, so that active and passive switching is realized, the processing process is not influenced, meanwhile, the workpiece is prevented from being damaged, and the turning processing efficiency and the workpiece processing precision are ensured.

Furthermore, the main transmission mechanism comprises a fixed disc, a sleeve, a driving shaft, a movable plate, a friction plate, a limiting block and a lever. The fixed disk is rotationally connected with the driving worm wheel, and the sleeve is positioned at one end, far away from the driving worm wheel, of the fixed disk. One end of the driving shaft extends to the inside of the fixed disc and penetrates through the movable plate to be connected with the friction plate, and the other end of the driving shaft is connected with the clamp to play a role in driving the clamp to rotate.
