A guide rod 14 with a T-shaped cross section is fixedly connected to the middle of one side of the two moving plates 12. The outer surfaces of the two guide rods 14 are rotatably connected to a rotating seat 15. A rectangular clamping plate 16 is fixedly connected to one side of the rotating seat 15. An arc clamping plate 17 is fixedly connected to the side of the rotating seat 15 away from the rectangular clamping plate 16. A fixing structure 18 for fixing the rotating seat 15 is provided on the top side of the rotating seat 15. When it is needed When clamping and fixing a cylindrical workpiece, first release the fixation of the rotating seat 15 through the fixing structure 18. At this time, the rotating seat 15 can rotate and make the arc-shaped clamping plate 17 rotate to the work position where the workpiece needs to be clamped.
