する測量機回転軸の微動・固定装置。[Claims for Utility Model Registration] A rotating shaft fixing mechanism that allows a fixed ring, into which a rotating shaft of a surveying instrument is loosely inserted, to be fixed to the rotating shaft under pressure; In a fixed and fine movement device that combines a fine movement mechanism that rotates slightly with A push rod is sandwiched between the rotary shaft press-welding stopper loosely fitted inside the ring, and a fixing knob is attached to the tip of a fixed shaft extending approximately coaxially with the camshaft, and the rear end and the above cam are attached. The fine adjustment mechanism has a fine adjustment tube shaft arranged so as to loosely insert the fixed shaft, and a fine adjustment tube with a diameter larger than the fixation knob at the tip of the fine adjustment tube shaft. At the same time as forming a knob for use, this fine movement cylinder shaft is screwed together with a fine movement female screw attached to the survey instrument main body frame, and a thrust bearing is provided between the rear end of this fine movement cylinder shaft and the rear end portion of the fixed shaft. In addition, a connecting pin is sandwiched between the rear end of the fixed shaft and the tip of the camshaft, and a spring is elastically installed between the fixed ring arm and the main body frame. Fine movement/fixing device for machine rotation axis.
