Claims

[Scope of utility model registration request]

In the threaded rod for position adjustment, the threaded portion of the threaded rod is threaded only at a certain angle in the cross section, and the threaded portion of the nut that is screwed into the threaded rod has a threaded area slightly wider than the threaded portion of the threaded rod. A relief groove is provided, which fits into a locking groove provided outside the threaded part of the threaded rod, and is guided in the radial direction by a guide groove provided in the nut, and the head is removed from the outer periphery of the nut. 1. A rapid length adjustment device, characterized in that a piece is provided that can freely appear and retract, and a sleeve that is movable from the top of the top of the piece to a position where it can be avoided is wrapped around the outer periphery of the nut.
