A connecting block 28 is fixed to each end of the rotating shaft 23, and the connecting block 28 is bolted to the top of the standard H-beam section 21 located at the top of the modular upright 2. The head of the crossbar 24 is screwed to the connecting block 28. The number of vertically assembled standard H-beam sections 21 can be selected according to the required lifting height.

[0034] The modular support frame 2 is vertically installed at the top center of the base 1. Specifically, four U-shaped steels 12 are fixed at the top center of the base 1. The U-shaped steels 12 are bolted to the bottom of the I-beam standard section 21 located at the bottom of the modular support frame 2.
