Description

  The present invention relates to an expansion / contraction adjustment localization device, and in particular, can easily adjust the position of an article to be placed and can easily determine the localization.

To meet the user's requirements, some properties can be adjusted to different locations based on the user's different state needs. For example, a chair seat, a backrest, or a desk height adjustment is adjusted to the optimum position for the user.
JP 2004-141676 A

    The problem to be solved is how the chair seat, chair back, desk or the like that adjusts the height is fixed at the adjusted position. Taking a desk as an example, in the case of a stepless height adjustment design, it is difficult to ensure localization, especially when the property placed on the desk is heavy (eg, peripheral equipment of a PC), even if it is a bar or support It is easy to come off even if it is supported with a spear. Further, in the case of localization by inserting into the localization hole, there is a problem that it is difficult to find the position of the localization hole into which the pin being operated is inserted.

  The present invention fits to the outside of the outer cover tube, an expansion tube which is placed in the outer cover tube and has a stereotactic hole installed in a plurality of axial directions, and the outer cover tube and the outer surface of the expansion tube intersect.
