[0024] like Figure 1-4 As shown, a limit rod 14 is fixedly connected between the fixed frame 11 and the connecting plate 6. The limit rod 14 is a cross-shaped structure, which limits the moving direction of the movable frame 13 to prevent rotation and deviation. The movable frame 13 is slidably connected with one end of the limit rod 14, and one end of the rotating shaft 7 passes through the side wall of the connecting plate 6 and is fixedly connected with the corresponding gear 16. The gears 16 are meshed with the corresponding racks 15.
