8. A protection method of a special grinder for grooving pre-operation demonstration scribing with a protection structure, which adopts the special grinder for grooving pre-operation demonstration scribing with a protection structure according to any one of claims 1-7, and comprises the following protection operation steps:
A. before the special grinder for grooving pre-operation demonstration scribing with the protective structure is needed, a worker pushes the slide block on the outer side of the positioning side plate, the slide block slides along the outer side of the positioning side plate to drive the moving plate fixedly connected with the side of the positioning side plate to move, the moving plate drives the limiting wheels at two ends to move on the inner side of the chute, and the limiting wheels are matched with the rotating circular shaft when moving, so that the whole fixing frame can slide on the inner side of the fixing groove under the acting force exerted by the moving plate, and the fixing frame moves to drive the supporting structure to move until the supporting rod moves out of the inner side of the fixing groove;
B. when the support rods move out of the inner side of the fixed groove, the staff continues to push the sliding blocks until the gears are meshed with the toothed plates at the corresponding positions, the upper two groups of support rods rotate upwards along with the gears, the lower two groups of support rods rotate downwards along with the rotation of the gears, the four groups of support rods synchronously rotate, and the plastic transparent protective layer arranged on the outer side is driven to stretch along with the support rods, so that a larger shielding plane is formed;
C. after the supporting structure is completely unfolded, a worker drives the blade to work after connecting the electric wire of the grinder body with a power supply, the worker performs grooving operation on the scribing part by controlling the fixed handle, the blade is connected with the wall surface to touch dust or waste water at the splashing position, the blade is completely shielded by the plastic transparent protective layer which is stretched to form a large shielding plane, and the worker can directly observe whether the grooving position is consistent with the scribing position or not through the plastic transparent protective layer due to the fact that the plastic transparent protective layer is self-developed, so that the position deviation of the opened channel is avoided.
