By maintaining a spaced apart state so that friction between the lifting pipes does not occur when lifting the lifting pipes, friction loss between the pipes can be prevented in advance, leading to an extension of the life of parts and cost reduction.

In addition, by providing a separate cushion body at the upper end of the lifting pipe so that the lifting pipe can be stably supported on the ceiling surface, as a result, the user can stably adjust the height without fear of the post falling. As a result, it is possible to prevent safety accidents and improve product reliability accordingly.

In addition, when a post composed of a plurality of pipes is configured, a separate joint having a connection function that is connected and fixed to only one pipe and a locking function that allows a pair of pipes to be relatively latched and supported, is provided, so that the lengths between the pipes are basically variable. As the expansion and contraction operation is performed smoothly, as a result, it is possible to provide convenience in use to the user, as well as a solid connection between pipes through a joint, thereby improving product stability.

As described above, one embodiment of the present invention has been described, but based on this, if a person of ordinary skill in the relevant technical field does not depart from the spirit of the present invention described in the claims, addition, change, and Various modifications and changes may be made to the present invention by deletion or addition, and this will also be included within the scope of the present invention.
