Further, the device for adjusting the height is composed of an outer tube and an inner tube, one side of the outer tube is provided with a row of adjusting holes along the length direction of the outer tube, the inner tube is provided with a spring pin which is matched and fixed with the adjusting holes of the outer tube, and the inner tube is perpendicular to the cross rod.

Further, base I and base II are two same circular bases, the top of base I and base II is equipped with articulated seat I respectively, outer welding of outer tube upper end has articulated seat II, the lower extreme of support column I outer tube articulates on articulated seat I at base I top, the lower extreme of support column II articulates on articulated seat I at base II top, the upper end of support column II articulates with articulated seat II on the outer tube upper end of support column I.

Further, the boxing component comprises a fixed rod and boxing balls, the lower end of the fixed rod is fixed on the upper side of the middle of the cross rod, and the boxing balls are arranged at the upper end of the fixed rod.

Further, the fixing rod and the cross rod are welded or in threaded connection.

Compared with the prior art, the utility model has the advantages that: the lower ends of the two support columns are respectively hinged with the two independent bases, after the two bases are fixed with the floor, the two support columns and the floor enclose a stable triangle, the fixation is firmer, and when one of the bases encounters a gap between the ceramic tiles, the fixing range is wide only by moving the position of the base which encounters the gap.
