Claims

[Scope of utility model registration request]

The coupling screw shaft at one end and the clamp at the other end are connected by a length-adjustable rod-like body consisting of a screw shaft and a cylindrical shaft that are telescopically screwed into each other, and the cylindrical shaft is connected to a plurality of axially The lock is composed of an outer tube having a fixing hole, and an inner tube that is movable in and out of the fixing hole so that it can be fitted into and removed from the fixing hole, and is equipped with a lock pin that is biased in the projecting direction by a spring. The pin is formed with a small-diameter neck portion in which a portion of the peripheral edge of the fixing hole fits when an axial tensile force or compressive force is applied to the cylinder shaft, at a portion passing through the fixing hole, and A wall connecting tool that is screwed onto the screw shaft and connects the outer tube to the coupling screw shaft.
