A screw 62 is fixedly installed between the central movable part of the bearing seat 61. The thread on the screw 62 is penetrated and connected with the movable block 2 to achieve synchronous rotation of the screw and the movable block. A rotating column 52 is movably connected at the top center of the damping rotating disk 51. A U-shaped belt frame 5 is fixedly installed at one end of the top of the rotating column 52. The damping rotating disk and the rotating column are used to realize the rotation of the U-shaped belt frame at different angles.
