[0039] The square sleeve body 501 is fixedly connected to the L-shaped telescopic frame square tube 301 via a limiting screw 502, and the limiting screw 502 passes through the sleeve limiting hole 503 and the L-shaped telescopic frame limiting hole 302;

[0040] The hook threaded rod 2 is configured to be L-shaped, with its bottom being clamped at a right angle to the bottom of the rectangular beam section 1, and its upper portion passing through and being clamped on the closed slot 306 and the open slot 305 in sequence. A thread 202 is provided on the top of the hook threaded rod 2 and is fixed to the angle steel 304 by a nut 203.

[0041] In some embodiments of the present application, the shape of the rectangular beam cross section 1 can be set to be a solid rectangle, a hollow rectangle or an H-shape.
