[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

In the same length of time, the present application can detect the flatness of the inner walls of more through holes, and when inserted, use a leveling platform to fit the surface of the cylinder body to achieve automatic leveling, thereby avoiding the problem of detection deviation due to uneven angles during subsequent detection. Compared with existing devices, the present application can achieve portable detection, easily take the detection device, and quickly insert it into through holes at different positions and angles, making detection easier.

[0015] 2. Start the hollow shaft motor to drive the fixed sleeve rod to rotate. When the fixed sleeve rod rotates, the limit protrusion and the limit groove are limited and slidably matched, so that the internal movable support rod will also rotate accordingly.

[0016] 3. By turning the knob, the upper rotating rod is driven to rotate, wherein the docking slot is used to dock with the docking socket, thereby driving the lower rotating rod to rotate and causing the first bevel gear to rotate. When the first bevel gear rotates, it will mesh with the second bevel gear, causing the worm to rotate, thereby realizing the meshing of the worm and the worm wheel. Under the rotation of the worm wheel and the cooperation of the limit block and the sliding groove, the horizontal position of the placement rod will be adjusted when the driving screw hole and the adjusting thread thread cooperate.

When the turntable rotates, the limiting thread ring and a number of thread ring limiting seats are used to limit the position, so that a number of slides can be driven to move outward at the same time, and the arc-shaped support seat is moved to the inner wall of the through hole for fixation, which not only ensures the stability during subsequent detection, but also makes it possible to use the synchronous movement of a number of slides before detection to ensure that the rotation center point of the micrometer measuring rod is aligned with the center of the through hole, so that no data deviation occurs during subsequent detection.
