When the grinding plate drives the tooth plate to rise, the U-shaped plate drives the push rod and the connecting block to rise, and the position of the connecting rod remains unchanged, thereby avoiding the possibility of the connecting rod falling off. At this time, the connecting rod drives the connecting block to make a back and forth reciprocating motion, so that the U-shaped plate drives the tooth plate to make a back and forth reciprocating motion, so that the tooth plate slides back and forth along the inner wall of the second limit groove, so that the tooth plate drives the gear to rotate, thereby driving the sixth rotating rod to rotate back and forth, so that the scraper first rotates forward 180 degrees and then reverses 180 degrees. The scraper with left and right symmetry is set to complete the scraping of debris adhered to the surface of the grinding plate, and avoids the blockage between the slag cleaning part and the blasting hole due to excessive debris.

[0017] 3. In the present invention, the reciprocating motion of the tooth plate causes the fourth support plate to drive the cleaning brush to perform reciprocating motion, thereby sweeping off the debris attached to the wall of the blasting hole. At this time, the debris is located at the bottom of the wall of the blasting hole. Before taking out the adjusting component and the cleaning component, the rotating motor is turned off by the control knob, and the grinding plate performs secondary cleaning on the wall of the blasting hole, making the wall of the blasting hole smoother and convenient for blasting operation. When the fourth support plate is taken out, it will drive the cleaning brush to perform reciprocating motion, sweeping out the debris accumulated at the bottom of the wall of the blasting hole, and completing the cleaning of the wall of the blasting hole. Larger debris can be swept out directly without the need for manual cleaning again. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] By contracting the grinding plate 501, the third spring 303 is in a stretched state, and the device is inserted into the blasting hole. Due to the contraction of the third spring 303, the two moving rings 304 move inward synchronously. The two moving rings 304 move inward horizontally through the limit of the key block 311 and the first limit groove 310, so that the first connecting rod 307 and the second connecting rod 309 are folded out, pushing the grinding plate 501, so that the grinding plate 501 is always in contact with the hole wall of the blasting hole, and the rotating motor 4 is started by the control knob 6.

The second spring 514 is set to ensure that the connecting rod 512 is always engaged with the inner wall of the cam 508. When the grinding plate 501 drives the tooth plate 516 to rise, the U-shaped plate 509 drives the push rod 510 and the connecting block 511 to rise, while the position of the connecting rod 512 remains unchanged, thereby avoiding the connecting rod 512 from falling off. 512 may fall off, at this time, the connecting rod 512 drives the connecting block 511 to reciprocate back and forth, so that the U-shaped plate 509 drives the tooth plate 516 to reciprocate back and forth, so that the tooth plate 516 slides back and forth along the inner wall of the second limiting groove 517, so that the tooth plate 516 drives the gear 520 to rotate, thereby driving the sixth rotating rod 521 to reciprocate, so that the scraper 522 first rotates 180 degrees forward and then reverses 180 degrees, and the scraper 522 that is set symmetrically on the left and right is used to scrape away the debris adhered to the surface of the grinding plate 501, thereby avoiding the blockage between the slag cleaning part and the blasting hole due to excessive debris; Due to the reciprocating motion of the tooth plate 516, the fourth support plate 8 drives the cleaning brush 7 to reciprocate, sweeping off the debris attached to the wall of the blasting hole. At this time, the debris is located at the bottom of the wall of the blasting hole. Before taking out the adjusting component 3 and the cleaning component 5, the rotating motor 4 is turned off by controlling the knob 6, and the grinding plate 501 performs secondary cleaning on the wall of the blasting hole, making the wall of the blasting hole smoother and convenient for blasting operation.
