By setting the replacement structure 4, when the sanitation brush body 3 is damaged and needs to be replaced, the personnel can first move the pull rod 414 to make the clamping block 413 away from the clamping groove 409, and then replace the turning handle 410. The rotation makes the adjusting block 405 move in the direction away from the moving block 403, and then the personnel moves the moving block 403 to make the moving block 403 slide out of the mounting groove 418, thereby achieving the effect of facilitating the personnel to replace the sanitation brush body 3. The end of the pull rod 414 away from the block 413 is fixedly connected with a pull ring 416, and the cross-section of the pull ring 416 is circular. The pull ring 416 can facilitate the personnel to move the pull rod 414, which can improve the convenience of operation of the personnel. The arc surface of the turning handle 410 is covered with several anti-skid sleeves 411, and the cross-section of the anti-skid sleeves 411 is a hollow circle. The anti-skid sleeves 411 can increase the friction between the personnel's hand and the turning handle 410, which can prevent the personnel from slipping when turning the turning handle 410. The inner wall sliding connection of the adjusting block 405 A limiting rod 404 is connected, and one end of the limiting rod 404 away from the moving block 403 is fixedly connected to the limiting groove 401. The limiting rod 404 can limit the adjusting block 405, so as to prevent the adjusting block 405 from being misplaced when sliding on the inner wall of the limiting groove 401. The limiting column 406 is a stainless steel column, which has the characteristics of high strength and good wear resistance. It is not easy to cause significant wear to the limiting column 406 during short-term use. Eight limiting blocks 417 are fixedly connected to the lower surface of the turntable 2. The eight limiting blocks 417 are grouped in pairs, and a group of limiting blocks 417 is evenly distributed at the notch of the installation groove 418. The limiting blocks 417 can limit the moving block 403, so that personnel can slide the moving block 403 into the inner wall of the installation groove 418 conveniently.

[0031] Working principle: when the sanitation brush body 3 is damaged and needs to be replaced, the personnel can first use the pull ring 416 to drive the pull rod 414 to move away from the slot 409, wherein the pull ring 416 can facilitate the personnel to move the pull rod 414, which can improve the personnel's operation convenience, and then the pull rod 414 drives the block 413 to move away from the slot 409, and the block 413 drives the spring 415 to contract. When the block 413 slides out of the inner wall of the slot 409, the personnel drives the turning handle 410 to rotate with the help of the anti-slip sleeve 411. The middle anti-slip sleeve 411 can increase the friction between the personnel's hand and the turning handle 410, and can prevent the personnel from slipping when turning the turning handle 410. Then the turning handle 410 drives the rotating plate 407 to rotate, and the rotating plate 407 drives the four limiting columns 406 to move in the direction close to the connecting column 1, wherein the limiting columns 406 can limit the adjustment block 405, and can prevent the adjustment block 405 from being misplaced when sliding on the inner wall of the limiting groove 401. Then the limiting columns 406 drive the adjustment block 405 to move in the direction away from the moving block 403, and the moving The block 403 slides on the arc surface of the limiting rod 404, wherein the limiting rod 404 can limit the adjusting block 405, and can prevent the adjusting block 405 from being misplaced when sliding on the inner wall of the limiting groove 401. When the adjusting block 405 moves to a suitable position, a person moves the four sanitation brush bodies 3 in a direction close to each other on the sanitation brush body 3, and the sanitation brush body 3 drives the moving block 403 to move in a direction close to the adjusting block 405. The adjusting block 405 slides on the inner walls of the auxiliary groove 402 and the installation groove 418. When it moves to the installation groove 418, the personnel moves the sanitation brush body 3 downward, and the sanitation brush body 3 drives the moving block 403 to move downward until the moving block 403 slides out of the inner wall of the installation groove 418. At this time, the personnel can replace the sanitation brush body 3, wherein the limit block 417 on the lower surface of the turntable 2 can limit the moving block 403, which can facilitate the personnel to slide the moving block 403 into the inner wall of the installation groove 418. By setting the replacement structure 4, it is convenient for personnel to quickly replace the sanitation brush body 3, thereby speeding up the work efficiency of the personnel.
