[0032] Specifically, when the cross plate 304 is pressed against the inner wall on one side of the knife groove 302, the cross plate 304 will fit against one end of the short cross bar 405, and the second spring 403 will be in a compressed state. At this time, the stop block 306 will move upward, causing the stop block 306 to be unable to block the cross plate 304. The second spring 403 will extend and push the second sliding plate 401 and the long cross bar 402 to move to the left. The long cross bar 402 drives the short cross bar 405 to move to the left through the transmission plate 404. The short cross bar 405 pushes the cross plate 304 to move to the left, causing a part of the cross plate 304 to slide out from the inside of the knife groove 302, making it convenient to pinch and pull out the cross plate 304, which is beneficial to the removal of the cutter 303.

[0033] Embodiment 3:

[0034] The driving assembly 5 includes a tension spring 501 and a servo motor 502.

[0036] Specifically, the servo motor 502 is started, and the servo motor 502 drives the half gear 505 to rotate through the transmission rod 504. When the half gear 505 is engaged with the rack block 506, the half gear 505 pushes the rack block 506 to move, and the rack block 506 will push the inclined rod 2 and the transmission ring 503 to move diagonally downward, and the transmission ring 503 will pull the tension spring 501 to cause the tension spring 501 to extend. When the half gear 505 rotates to no longer engage with the rack block 506, the tension spring 501 will shorten and pull the transmission ring 503 to move in the opposite direction. The transmission ring 503 pushes the rack block 506 through the inclined rod 2 until the dovetail bar 507 is supported by the inner wall of the dovetail groove 6, prompting the rack block 506 to return to its original position. Therefore, the servo motor 502 drives the half gear 505 to rotate, so that the movable seat 301 reciprocates back and forth.

[0037] When the cutting knife 303 is needed to be replaced, the flat push plate 317 is pushed rightward, and the flat push plate 317 drives the limiting rod 312 to move rightward through the first sliding plate 311, causing the limiting rod 312 to disengage from the limiting hole 309, and then the lifting plate 315 is pushed upward, and the lifting plate 315 drives the stopper 306 to move upward, causing the stopper 306 to move from the bottom of the slot 305 to the top of the slot 305, at this time, the stopper 306 cannot resist the cross plate 304 in the horizontal direction, so the second spring 403 will extend and push the second sliding plate 401 and the long cross bar 402 to move leftward, and the long cross bar 402 drives the short cross bar 405 to move leftward through the transmission plate 404, and the short cross bar 405 will push the cross plate 304 to move leftward, causing a part of the cross plate 304 to slide out from the inside of the knife groove 302, making it convenient to pinch and pull out the cross plate 304, which is conducive to the removal of the cutting knife 303;

[0038] The first spring 310 extends and pushes the first sliding plate 311 and the limiting rod 312 to move, and the limiting rod 312 slides into the limiting hole 309, completing the fixing of the block 306 and consolidating the limiting effect of the block 306 on the horizontal plate 304.

[0039] When it is necessary to clean the insulation layer of the building's exterior wall, start the servo motor 502, and the servo motor 502 drives the half gear 505 to rotate through the transmission rod 504. The servo motor 502 drives the half gear 505 to rotate, so that the movable seat 301 moves back and forth. The movable seat 301 drives the cutter 303 to move back and forth through the knife groove 302 and the cross plate 304. The user uses the handle 9 to push the device to move on the wall, so that the insulation layer on the building's exterior wall can be quickly cleaned.
