Detailed Description

In the embodiment, referring to fig. 1 to 4, the device for improving the measurement accuracy of the drilled hole includes a half pipe a 1 and a half pipe B2 which are independent from each other and are arranged oppositely; the screw 9 arranged along the axial direction of the half-pipe A1 is arranged in the half-pipe B2, the hinge mechanism is arranged in the half-pipe B2, the rocker arm 5 is arranged on the screw 9, the rocker arm 5 extends into the half-pipe B2 and is hinged and fixed with the hinge mechanism, and the half-pipe B2 can be driven to move away from or close to the half-pipe A1 by rotating the screw 9 through the rocker arm 5, so that the half-pipe B2 and the half-pipe A1 are opened or closed.

A fixing frame 4 is arranged in the A half pipe 1, a nut 8 is fixed on the fixing frame 4, and a screw 9 penetrates into the nut 8 to form a structure capable of moving along the axial direction of the A half pipe 1 through rotation.

The nut 8 is arranged at a position close to the middle of the A half pipe 1, so that the screw 9 is close to the middle of the A half pipe 1.

At the end of the half-pipe a 1, a full pipe section 11 is provided, the diameter of the full pipe section 11 being the same as the diameter of the half-pipe a 1 and the half-pipe B2 when they are completely closed.
