Multiple telescopic positioning rods 42 jointly drive the pressing block 43 and the rubber pad 44 to move. After the second threaded sleeve 41 moves to the outer edge of the screw 39, the pressing block 43 and the rubber pad 44 are moved to fit the outer wall of the movable plate 15 by using the telescopic movement of multiple groups of telescopic positioning rods 42. Subsequently, when the user applies force to the movable plate 15 by kicking, the movable plate 15 will push the two pressing blocks 43 to move. The two pressing blocks 43 respectively push the corresponding multiple telescopic positioning rods 42 to move synchronously. Multiple telescopic positioning rods 42 jointly drive the second threaded sleeve 41 to move. The second threaded sleeve 41 drives the screw 39 to move.
