The inside of the lateral support cantilever 11 is provided with a transverse internal thread adjustment hole 12 and a transverse guide through hole 13. The side wall of the lateral support cantilever 11 is provided with a lateral storage groove 14 with a built-in elastic flip support mechanism.

[0024] Furthermore, in order to improve the stability of the lateral support cantilever 11 during the lifting and translation process, a longitudinal guide groove 15 and a transverse guide groove 16 connected to the longitudinal guide groove 15 are provided on the side wall of the longitudinal support frame 1, and an internal transition block 17 that cooperates with the elastic flip support mechanism is bolted to the inner side of the transverse guide groove 16.

[0025] Furthermore, in order to reduce the resistance and friction of the extrusion adjustment type, both ends of the internal transition block 17 are provided with arc-shaped transition blocks 18 that cooperate with the elastic flip support mechanism.
