The movable guide rail 102 is fixedly connected to the compensation cabinet 101 and is arranged inside the compensation cabinet 101. The movable block 103 is a rectangular block with a threaded through hole. The movable block 103 is slidably connected to the movable guide rail 102 through an internal roller and is arranged in the rectangular movable groove of the movable guide rail 102. The movable push rod 104 is a cylindrical rod with an external thread. The external thread of the movable push rod 104 is engaged with the threaded through hole of the movable block 103. The movable push rod 104 is rotatably connected to the movable guide rail 102 through a bearing and rotates along the threaded through hole.
