The other type of inner and outer round tube lifting is also round in appearance but is limited by the internal structure space of the profile. The inner and outer tubes need to have a more obvious size difference or need to be connected with a transition piece to improve the size difference between the inner and outer tubes. More parts need to be opened for molding, and the production and installation are complicated and the product development cycle is long. Utility Model Content
