装置。 The base material is provided with an opening into which the rod is slidably inserted, and a cap-shaped operating member with a through hole through which the rod is passed is rotatably attached, and the operating member is normally reduced in diameter to form a substantial inner diameter. A helically wound tightening spring with a diameter smaller than the diameter of the rod is built in, and the spring is wound around the circumference of the rod to keep it tightly held at all times, while one end of the spring is attached to the base material. , and a rod expansion/contraction movement restraint in which the other end is brought into contact with the operating member, and by rotating the operating member, the spring is expanded and the tension is released, thereby allowing the rod to freely extend and contract. Device.
