The bottom plate 1 and the top plate 2 are fixed to the side plate 3 by bolts. A top rod stud 4 is screwed at the middle position of the top plate 2, and the top rod stud 4 is screwed to the top plate 2. A top block 5 is arranged at the bottom of the top rod stud 4. The lower surface of the top block 5 is a concave arc surface, and the arc surface is adapted to the upper surface of the shaft seat. A pressing hole is opened on the upper surface of the top block 5, and the top block 5 is suspended under the top rod stud 4 through the pressing hole. The lower end of the top rod stud 4 has a smooth section without thread, and the pressing hole is suspended on the part of the smooth rod, and when the top rod stud 4 moves downward, its smooth section can be pressed against the bottom of the pressing hole. A clamping wheel 6 is arranged at the middle position of the upper surface of the base plate 1. The clamping wheel 6 is rotatably mounted on the base plate 1 through an eccentric shaft 7. The clamping wheel 6 is eccentrically fixed to the upper end of the eccentric shaft 7. The eccentric shaft 7 is rotatably mounted on the base plate 1 through a bearing. A nut is coaxially fixed to the lower end of the eccentric shaft 7. The eccentric shaft 7 and the clamping wheel 6 are driven to rotate by rotating the nut.
