However, this circular hole cutter does not have a centering structure, so it is easy to slip when it encounters marble, tile or smooth wall surface, and it is impossible to drill stably. ^ For this reason, there is another customary creation. Please refer to the second picture, which is the application of the case number 93214868, "Cave Diamond Drill Pipe Structure of Concrete Drilling Machine, (=2). The second system consists of a joint, a pipe, a drill bit, a medium=with a screw hole, which can be disassembled and mounted on the threaded portion of the rotor of the motor, and a flange is provided on the surface for a plurality of diamonds to be arranged at intervals. There is a center thimble and a fixed piece, and the center thimble is provided with a spring member to hunt to fix the smooth wall surface by using the center thimble. In this winter, the second thimble is placed at the top edge of the inner edge of the round tube. Therefore, when the crop is cropped, the center thimble will also rotate with it. The effect of the inevitable adverse effects, but has been improved, people in the research and development and manufacturing of related industries for many years. According to the invention, the heart of the round hole mining machine has been successfully created [invention content] damping 机构 position mechanism, wrong To improve the above mentioned lack. The main object of the present invention is to provide a center damper positioning machine of a hole mining machine, 1277472, a machine drill = the center of the f-pointing machine, and the center of the 11-hole end of the dam is set.
