Claims

[Claims for Utility Model Registration] A fixed cylinder 3 is fixed to the outer circumferential surface of the end of the outer shaft 1 into which the inner shaft 2 is inserted so as to be freely drawn out.
The operating screw tube 4 is screwed onto the outer periphery of the slide tube so that it can move forward and backward, and the other half of the sliding tube body 5, one half of which extends toward the inner shaft 2, is fitted over the outer periphery of the slide tube 4. body 5
A locking mechanism 6 is disposed on one half of the sliding cylinder 5 extending toward the inner shaft 2 and press-fitted to the inner shaft 2 so as to be able to move toward and away from the inner shaft 2 by rotational operation. Furthermore, contact members 19 and 20 are provided at the outer ends of the outer shaft 1 and the inner shaft 2, and these contact members 1
A pole characterized in that at least one of the contact members 9 and 20 is constantly pressed outward by a spring force. The locking mechanism 6 includes a screw 8 inserted and supported in a radial direction at a proper position on the peripheral wall of the sliding cylinder 5.
A claim in which one end of the screw 8 is fixed to a tightening ring 9 that is loosely fitted to the inner shaft 2, and the handle body 7 is rotatably screwed into the threaded portion of the other end protruding from the sliding cylinder 5. Paul mentioned. The locking mechanism 6 has a lever 7a pivotably mounted on the circumferential wall of the sliding cylinder 5 at a proper position so as to be able to freely raise and lower.
A pole according to claim 1, further comprising a cam surface (31) that presses against the outer peripheral surface of the pole.
