In addition, an anti-slip support plate 10 is fixed on the bracket 2, and an anti-slip head 9 is provided on the connecting column 8. The outer diameter of the anti-slip head 9 is larger than the outer diameter of the connecting column 8, and the connecting column 8 penetrates the anti-slip support plate 10 so that the anti-slip head 9 is placed above the anti-slip support plate 10. Specifically, the anti-slip support plate 10 can be sleeved on the connecting column 8, so that the three-jaw chuck 7 and the connecting column 8 can be detachably connected.
