The bevel gear 3 meshes with a bevel gear 4. The center of the top of the bevel gear 4 is fixedly connected with an elliptical disk 5. Both ends of the top of the elliptical disk 5 are hinged with a connecting rod 6. The end of the connecting rod 6 is hinged with a fixture base 7. The vertical rod of the fixture base 7 is square to prevent the elliptical disk 5 from rotating and driving the fixture base 7 to rotate, resulting in the inability to clamp the workpiece. The outer wall of the top of the fixture base 7 is connected with a clamping block 8 through a quick-release component. The clamping surface of the clamping block 8 is provided with an arc surface, and different-shaped fixtures can be replaced through the quick-release component. The inner wall of the housing 1 is fixedly connected with a fixing plate 9, and the fixing plate 9 is used to assist the rotation of the elliptical disk 5 and provide a supporting effect to prevent the elliptical disk 5 from falling off due to insecure hinging. The bottom of the inner wall of the housing 1 is fixedly connected with an auxiliary rod 10, and the auxiliary rod 10 is used to assist the rotation of the rotating shaft 2 to keep it rotating on the same horizontal line and prevent the bevel gear 3 from falling due to unstable limiting. The outer wall of the rotating shaft 2 is slidably connected to the inner wall of the auxiliary rod 10, and the end of the rotating shaft 2 is rotatably connected to the inner wall of the housing 1. The outer wall of the bevel gear 4 is slidably connected to the bottom of the fixing plate 9, and the bottom of the elliptical disk 5 is slidably connected to the top outer wall of the fixing plate 9. The outer wall of the fixture base 7 is slidably connected to the top inner wall of the housing 1.

[0034] Referring to Figures 3 - 5 , the clamping component includes a slider 12. The slider 12 is set to be square, which is used to keep the slider 12 can slide in the chute 11 and can also drive the rotating shaft 2 to rotate. The outer wall of the slider 12 is elastically connected to the inner wall of the chute 11 through a limiting spring 13. The outer end of the slider 12 is fixedly connected with a rocker 14. The outer wall of the rocker 14 is fixedly connected with a limiting block 15. There are eight groups of limiting blocks 15 arranged around the outer wall of the rocker 14, and the number can be changed according to actual needs, which is used to clamp and limit the ring 16 at multiple angles so that the rotating shaft 2 will not rotate without external force. The outer wall of the limiting block 15 is clamped with a limiting ring 16. The inner wall of the limiting ring 16 is provided with a groove corresponding to the limiting block 15. The outer wall of the slider 12 is slidably connected to the inner wall of the chute 11. The outer wall of the limiting ring 16 is fixedly connected to the outer wall of the housing 1.
