According to the invention, due to the adoption of the thread type right pressing and the simultaneous or synchronous rotation generated when the motor drives to rotate, the polishing head can be driven to synchronously polish and rotate left and right, only one motor is used, and the equipment cost is reduced in combination with the condition of locally protruding polishing amount. Meanwhile, the thread pair can be replaced at any time according to different polishing materials and polishing requirements by using the convenient replacement arrangement of the related parts of the thread matching pair, so that the right pressing speed is adjusted; on the basis, the diameter of the end hole provided with the external thread sleeve is larger than the diameter of the polishing head mounting rod, so that the polishing head mounting rod can move out rightwards without interference of the mounting rod and be detached (only the polishing head and the sealing cover plate need to be detached), meanwhile, the diameter of the thread matching pair can be increased, the reaction force bearing action surface during polishing is increased, and the thread lead is optionally increased or the thread lead angle is optionally reduced. Simultaneously, the diameter that sets up the telescopic right-hand member flange of internal thread is less than the diameter of shell hole, can guarantee removing smoothly of internal thread sleeve. Therefore, the external thread sleeve and the internal thread sleeve can be integrally removed in a matched manner, and the disassembly, assembly and maintenance are facilitated. The flexibility of the device is increased. And set up the shank component that can utilize pneumatic cylinder automatically regulated height to the cooperation uses the spirit level, can be according to the actual plane profile on road surface and the levelness of on-the-spot quick adjustment whole equipment, thereby it can guarantee the processing plane degree after the completion to polish when polishing to make the regulation accurate. The whole equipment is reliable in operation and stable in structure, and the overall cost of hole digging can be reduced.
