A turntable 8 is fixedly connected to the outer wall of the screw 6. The turntable 8 drives the screw 6 to rotate forward or in the opposite direction by manual force, thereby causing the two sets of slide seats 9 on its surface to move relative to each other. The slide seats 9 are threadedly connected to the outer wall of the screw 6. A support block 10 is slidably connected to the outer wall of the slide rod 7. A connecting frame 11 is fixedly connected to the outer wall of the support block 10.
