The lower clamping block 75 is internally movably connected to a limit rod 77. Through the cooperation of the clamping structure 7 and the limit block 4, after the cross bar 5 is inserted into the column 1, the bevel gear 72 is driven to rotate by rotating the hand screw 71. The two bevel gears are engaged to drive the screw rod 74 to rotate. There are two sets of opposite threads on the screw rod 74, so that the two sets of clamping blocks cooperating with the threads move toward the center to fix the cross bar 5. The limit block 4 is inserted into the groove on the surface of the cross bar 5 to further fix the cross bar 5. An adjustment structure 2 is set. The height of the device can be adjusted by adjusting the relative position of the column 1 and the fixed column 23 up and down and fixing it with the fixing bolt 24, which has higher applicability.

[0024] Furthermore, the bottom plate 21 abuts against the surface of the column 1 , and the bottom plate 21 and the column 1 are in contact but not fixed.

[0025] Furthermore, a circular groove 1 is provided on the surface of the fixing column 23, and a circular groove 2 is provided on the surface of the column 1. A fixing bolt 24 passes through the circular groove 1 and the circular groove 2 to connect the fixing column 23 and the fixing bolt 2 24.
