b: after the step A is finished, when the height of the ground, protruding out of the ground, of the polished stone exceeds the range capable of being polished by the polishing piece, if the stone is not tightly fixed with cement, the annular plate and the auxiliary supporting plate push the stone away in the moving process of the machine body, if the stone is tightly fixed with the cement, the arc-shaped auxiliary supporting plate is pushed to move to the top of the stone by the thrust in the moving process of the machine body, the polisher slightly inclines, and the first baffle and the second telescopic rod play a supporting role in the process of jacking the auxiliary supporting plate by the stone to prevent the auxiliary supporting plate from being broken due to overlarge extrusion force;
c: after the step B is finished, when the auxiliary supporting plate is positioned at the top of the stone, the self-weight auxiliary supporting plate deforms, the first baffle plate upwards extrudes the pressure sensor, the pressure sensor is extruded, the position of the stone to be polished can be determined, an air bag in the auxiliary supporting plate opposite to the position of the stone is inflated to drive the first telescopic rod and the second telescopic rod to extend out, the auxiliary supporting plate at the position plays a role of a supporting point, the polishing piece is suspended, and the polishing of the ground when the polishing piece inclines is avoided;
d: accomplish the C step back, the organism slope, the other supporting mechanism of strong point slopes thereupon, make the non slipping spur touch, the bracing piece shell passes through rotation axis angle regulation, play the effect of auxiliary stay, the auxiliary stay board of avoiding strong point department bears the gravity of whole polisher, through removing the organism, make the piece of polishing remove the top of this stone, then push down, polish to it, the distance between piece of polishing and the annular plate is little, can avoid the stone to block, the stone is directly polished and is accomplished, the work efficiency of ground polisher is improved.
