Sliding holes are provided on both sides of the U-shaped frame 3, and the inner surfaces of the sliding holes of the U-shaped frame 3 are slidably connected to sliding rods 6, and one end of the sliding rod 6 is fixedly connected to the limiting plate 5. The rotating threaded rod 4 rotates in the U-shaped frame 3, and the threaded rod 4 drives the limit movement. The limit plate 5 drives the sliding rod 6 to slide on the inner surface of the sliding hole of the U-shaped frame 3, preventing the limit plate 5 from rotating with the rotation of the threaded rod 4.

The side of the mounting plate 10 close to the special-shaped frame 7 is fixedly connected with a spring 11, and the other end of the spring 11 is fixedly connected with the special-shaped frame 7. The elastic force of the spring 11 drives the plug plate 9 to slide in the special-shaped frame 7 and automatically insert into the limiting groove of the baffle plate 8, thereby improving the convenience of the device.
