緊締装置。[Claims for Utility Model Registration] (1) In a device for tightening an actuating arm via a tightening piece by advancing a push rod by the forward force of a tightening force introducing shaft screwed into the side surface of the actuating arm, A fine adjustment screw is screwed into a screw receiver provided in the main body casing in front of the force introduction shaft, and a tightening shaft is supported rotatably but not forward or backward at the axis of the fine adjustment screw, and the actuation arm is mounted around the tightening force introduction shaft. The rear end of the tightening force introduction shaft is fused to a cup-shaped support crown whose side surface is in contact with the peripheral surface of the tip opening, and the rear end of the tightening force introducing shaft is connected with a pin so as to be freely advanced and retracted in the axial direction. A tightening device in a fine movement device for a surveying machine, characterized in that the tip ends of the shafts are connected via a universal joint, and the sharp tip of the tightening shaft is brought into contact with the rear end surface of the support crown. (2) A request for registration of a utility model characterized in that a stopper is provided around the tip of a tightening shaft protruding from the tip of a fine adjustment screw, and a regulating protrusion is provided around the rotating part of the stopper to regulate the rotation range of the stopper. A tightening device in a fine movement device of a surveying machine according to item 1. (3) A locking part is provided around the base end of the tip of the tightening shaft that protrudes from the tip of the fine adjustment screw, and a sliding ring is inserted between this locking part and the tip of the fine adjustment screw, and the sliding ring is Utility model registration claim 1, characterized in that a part of the outer periphery is slidably engaged with a guide provided in parallel to the advancing and retreating direction of the fine adjustment screw.
A tightening device in a fine movement device of a surveying machine according to item 1 or 2.
