The length direction of the sliding rod 82 is perpendicular to the length direction of the connecting rod 5. The sliding rod 82 penetrates the connecting rod 5 and is slidably connected to the connecting rod 5. One end of the sliding rod 82 away from the clamping block 81 is fixedly connected to a limiting plate 91. The limiting plate 91 is perpendicular to the sliding rod 82. A spring 92 is fixedly provided between the clamping block 81 and the inner bottom wall of the movable groove 9. The spring 92 is sleeved outside the sliding rod 82, and the side of the clamping block 81 away from the spring 92 is set as an inclined surface.
