Convex sliders 7 are installed on both sides of the lifting block 6. The inner wall of the cavity base 2 is provided with a left-right direction as the depth direction and a front direction as the back direction. The rear direction is the length direction of the positioning slide groove, and a positioning slider 8 is arranged inside the positioning slide groove. A trapezoidal block 9 is installed on one side of the positioning slider 8. The inclined surface of the trapezoidal block 9 is provided with a convex slide groove with a depth direction perpendicular to the inclined surface of the trapezoidal block 9 and a length direction parallel to the inclined surface of the trapezoidal block 9. The end of the convex slider 7 is located inside the convex slide groove, and the convex slider 7 can slide along the length direction of the convex slide groove. A connecting rod 10 is installed on one side of the trapezoidal block 9, and a limiting clamp 11 is installed on the end of the connecting rod 10. There are two limiting clamps 11, and a rubber pad 26 is arranged on the side of the limiting clamp 11 away from the connecting rod 10.
