The side wall of the movable splint 13 away from the fixed block 12 is an arc surface, and the surface of the arc surface is provided with anti-slip lines. The movable splint 13 and the fixed block 12 are connected by two buckle mechanisms. The buckle mechanism includes a special-shaped clamping block 15 arranged on the same side of the fixed block 12 and the movable splint 13. The special-shaped buckle 15 is a structure with one end protruding. A rectangular groove 17 is opened on one side of the fixed block 12. A pressing spring 16 is fixedly connected to the inner side wall of the rectangular groove 17. The end of the pressing spring 16 away from the rectangular groove 17 is fixedly connected to the side wall of one end of the special-shaped clamping block 15. A special-shaped groove 18 with the same protruding shape as the other end of the special-shaped clamping block 15 is opened on one side of the movable splint 13. A rotating shaft 8 passes through and is fixedly connected to the middle of the special-shaped clamping block 15. Both ends of the rotating shaft 8 are rotatably connected to a support plate 14, and both support plates 14 are fixedly connected to the side wall of the fixed block 12.

[0023] When the present utility model is in use, the worker first presses one end of the special-shaped clamping block 15 located at the pressing spring 16. With the cooperation of the support plate 14 and the rotating shaft 8, the end of the special-shaped clamping block 15 away from the pressing spring 16 is lifted up and disengaged from the special-shaped groove 18 on one side of the movable splint 13, so that the movable splint 13 can be detached and fixed, and then the movable splint 13 can be replaced. After replacement, the handle 5 is pulled to drive the insertion post 6 to lift or lower, so that the insertion post 6 is inserted into or disengaged from the hole groove on the sliding rod 10, so that the fixed block 12 at one end of the sliding rod 10 moves or is fixed, indirectly driving the movable splint 13 to move or be fixed. When the movable splint 13 moves towards the position of the fixed splint 2, the drive shaft bracket can be clamped and fixed.
