The top support 3 and the bottom support 4 are located in the middle of the U-shaped frame 6. The movable seat 5 has a through-hole for the column 2 to pass through at its center. The column 2 has connecting structures evenly spaced along the vertical direction. The movable seat 5 is detachably connected to any one of the connecting structures. Both ends of the movable seat 5 have through slots. The two ends of the U-shaped frame 6 are slidably disposed in the two through slots. The movable seat 5 has two symmetrical sliding grooves inside. The two ends of the sliding grooves are connected to the through-hole and the through slot, respectively. The fastening members 7 are slidably disposed in the sliding grooves one by one. One end of the fastening member 7 is engaged with the inclined surface of the U-shaped frame 6.

[0030] The movable seat 5 includes a rectangular frame 52, an upper plate, a lower plate 51, and two guide frames 53. The upper and lower ends of the rectangular frame 52 are respectively located at the center of the upper plate and the lower plate 51. The guide frames 53 are located inside the rectangular frame 52 and at both ends of the rectangular frame 52. The sliding groove is located in the middle of the guide frame 53.
