The fourth step: drive threaded rod 27 through start-up driving motor 29 and rotate, threaded connection through removing frame 30 and threaded rod 27, utilize the opposite screw thread in threaded rod 27 both ends simultaneously, make the torsional force that produces when threaded rod 27 rotates drive the removal frame 30 at both ends and carry out the ascending removal in mutual direction, the removal through removing frame 30 drives the both ends of second gyro wheel 31 and modularization building connection spare and contacts, when making the modularization building connection spare remove, through the contact with second gyro wheel 31, the completion is stabilized it and the secondary positioning.

The fifth step: during polishing, through the spraying structure, dust removal treatment is carried out on the modular building connecting piece when the modular building connecting piece is polished, water in the water tank 34 is pumped out by starting the water pump 35 and is conveyed into the spraying pipeline 37 through the guide of the conveying pipeline 36, the water in the spraying pipeline 37 is atomized and sprayed out through the atomizing nozzle 38, flying dust is captured through the atomized water and falls on the surface of the modular building connecting piece, the modular building connecting piece is cleaned through the steps in the third step, and the coarse grinding roller 10 and the fine grinding roller 11 are cooled through the contact of water mist with the coarse grinding roller 10 and the fine grinding roller 11.
