Claims

[Scope of Claim for Utility Model Registration] (1) A long outer cylinder is provided with a central shaft that is slidable in the longitudinal direction of the external cylinder, and a rotating hook that can be moved in and out from one end of the external cylinder is attached to the upper end of this central shaft. A spring is provided on this center shaft to bias the hook so that it always protrudes from one end of the outer cylinder, and a handle case is provided on the end of the outer cylinder opposite to the hook, and one end is attached to the handle case as a shaft. A pinion shaft is loosely passed through the long hole of the supported handle, and a first pinion gear with a large diameter and one clutch is fixed to this pinion shaft and is meshed with a first rack provided at the rear of the center shaft, which is also fixed to the pinion shaft. 1. A grip clamp stay, characterized in that a locking device is provided on the outer cylinder for fixing the center shaft by meshing a small diameter second pinion gear with a second rack provided on the handle case. (2) The locking device for fixing the center shaft is mounted on the outer cylinder, and is attached to the center shaft through a long hole in the outer cylinder through a ratchet pawl at the tip of a lock lever that is pivotally supported on a sliding tube that slides in the axial direction of the outer cylinder. Claims for registration of a utility model, characterized in that a threaded portion provided on the outer periphery of the sliding tube is screwed into a nut rotatably provided on the outer periphery of the outer cylinder, which is engaged with a third rack provided on the side. Grip clamp stay as described in section 1).
