A movable plate 30 is installed at the upper end of the work-type seat 28, and an inclined hole 31 is opened on the movable plate 30. The upper end of the inclined hole 31 extends inwardly. A pair of vertical rods 34 are installed at the lower end of the rectangular frame 22. The upper ends of the vertical rods 34 are sleeved with a movable frame 33. The lower wall of the movable frame 33 is provided with two pairs of protrusions, and a movable rod 32 is provided between each pair of protrusions. The movable rod 32 passes through the inclined hole 31. A first spring 35 is provided on the lower side of the movable frame 33, and the first spring 35 is sleeved on the vertical rod 34.
