The bottom end of the lower support rod 6 passes through the sliding sleeve 8 and the limiting groove 7 in sequence and is slidably connected to the sliding sleeve 8. The bottom of the L-shaped fixing plate 3 and the lateral sides near the edge are symmetrically fixedly connected with the supporting plates 9. A screw 10 is rotatably connected between the two supporting plates 9 and away from the bottom corner of the upper support rod 1. One end of the screw 10 away from the L-shaped fixing plate 3 passes through one of the supporting plates 9 and is fixedly connected with a turntable 12. The end of the screw 10 away from the L-shaped fixing plate 3 exceeds the length of the L-shaped fixing plate 3. After the turntable 12 is installed, it will not form movement interference with the L-shaped fixing plate 3. The outer side of the screw 10 is threadedly connected with a slide plate 11. The support plate 9 and the slide plate 11 can be extended downward according to the needs of use for easy adjustment. The slide plate 11 is fixedly connected to the bottom edge of the sliding sleeve 8. The slide plate 11 will not touch the lower support rod 6 when moving on the screw 10.
