Then the screw rod drives the clamping block to move away from the auxiliary groove. The clamping block is a stainless steel block, which has good wear resistance and large strength, and is not easy to cause significant wear to the clamping block during short-term use. Then the clamping block slides on the arc surfaces of the two limiting rods. The limiting rods can limit the clamping block, preventing the clamping block from being misaligned when sliding on the inner wall of the connecting groove until the clamping block slides out of the inner wall of the auxiliary groove. At this time, the personnel drive the auxiliary block to move away from the limiting groove by means of the grip. The grip can facilitate the movement of the auxiliary block by personnel, improving the operation convenience of the personnel. Then the two auxiliary blocks drive the cleaning brush to move away from the limiting groove until the auxiliary block slides out of the inner wall of the limiting groove. Then the personnel continue to move further away from the limiting groove to make the cleaning brush slide out of the arc surface of the piston. At this time, the personnel can replace a new cleaning brush. The plurality of limiting blocks on the side of the fixing ring away from the connecting column can limit the auxiliary block, facilitating the personnel to slide the auxiliary block into the inner wall of the limiting groove. By setting the cleaning structure, the effect of cleaning the dust on the surface of the piston is achieved, preventing the dust from entering the inside of the cylinder barrel along with the piston, which will affect the normal use of the piston after a long time, and also improving the subsequent replacement speed of the cleaning brush by the personnel, improving the work efficiency of the personnel.

[0026] Next, specifically describe the specific settings and functions of its cleaning structure 4.

[0027] Referring to Figures 2 to 4As shown in the figure, in this implementation scheme: The cleaning structure 4 includes two connecting plates 401. On one side of the two connecting plates 401 close to each other, there is a fixed ring 402 fixedly connected. The inner wall of the fixed ring 402 is provided with two limiting grooves 404 and two connecting grooves 414. The limiting groove 404 and the connecting groove 414 communicate with each other. The inner wall of the connecting groove 414 is slidably connected with a clamping block 408. One side of the clamping block 408 away from the limiting groove 404 is rotatably connected with a lead screw 409. The lead screw 409 is threadedly connected with the fixed ring 402. One end of the lead screw 409 away from the clamping block 408 is fixedly connected with a rotating column 411. The inner wall of the limiting groove 404 is slidably connected with an auxiliary block 406. The inner wall of the auxiliary block 406 is provided with an auxiliary groove 407. The auxiliary groove 407 is slidably connected with the clamping block 408. On one side of the two auxiliary blocks 406 close to each other, there is a cleaning brush 403 fixedly connected. By setting the cleaning structure 4, the effect of cleaning the dust and debris attached to the surface of the piston 7 can be achieved, which can prevent the dust from entering the inside of the cylinder barrel 3 along with the piston 7. If this continues for a long time, it will affect the normal use of the piston 7. The inner wall of the connecting groove 414 is fixedly connected with two limiting rods 410. The two limiting rods 410 are slidably connected with the clamping block 408. The limiting rods 410 can limit the clamping block 408 and prevent the clamping block 408 from being misaligned when sliding on the inner wall of the connecting groove 414. The inner wall of the rotating column 411 is provided with a number of anti-slip grooves 412. The anti-slip grooves 412 are evenly arranged on the rotating column 411. The anti-slip grooves 412 can increase the friction between the human hand and the rotating column 411 and prevent the person from slipping when rotating the rotating column 411. The upper surface of the fixed ring 402 is fixedly connected with a number of limiting blocks 405. The number of limiting blocks 405 is evenly distributed at the openings of the two limiting grooves 404. The limiting blocks 405 can limit the auxiliary block 406 and facilitate the person to slide the auxiliary block 406 into the inner wall of the limiting groove 404. One side of the auxiliary block 406 away from the connecting column 5 is fixedly connected with a handle 413. The handle 413 is in a "U" shape. The handle 413 can facilitate the person to move the auxiliary block 406 and improve the operation convenience of the person. The clamping block 408 is a stainless steel block. The cross section of the clamping block 408 is rectangular. The stainless steel block has good wear resistance and large strength, and it is not easy to cause large wear to the clamping block 408 during short-term use.

[0028] Working principle: When air is introduced into the interior of the cylinder barrel 3 to retract the piston 7 into the interior of the cylinder barrel 3, the dust and impurities adhering to the surface of the piston 7 can be removed by the cleaning brush 403. When the cleaning brush 403 needs to be replaced after long-term use, the operator can first drive the lead screw 409 to rotate by means of the rotating column 411, so that the lead screw 409 moves away from the auxiliary groove 407. The anti-slip groove 412 formed on the inner wall of the rotating column 411 can increase the friction between the operator's hand and the rotating column 411, and can prevent the operator from slipping when rotating the rotating column 411. Then, the lead screw 409 drives the clamping block 408 to move away from the auxiliary groove 407. The clamping block 408 is made of stainless steel, which has good wear resistance and high strength, and is not easily worn significantly after short-term use. Then, the clamping block 408 slides on the arc surface of the two limiting rods 410. The limiting rods 410 can limit the clamping block 408 and prevent the clamping block 408 from being misaligned when sliding on the inner wall of the connecting groove 414 until the clamping block 408 slides out of the inner wall of the auxiliary groove 407. At this time, the operator drives the auxiliary block 406 to move away from the limiting groove 404 by means of the handle 413. The handle 413 can facilitate the operator to move the auxiliary block 406 and improve the operation convenience of the operator. Then, the two auxiliary blocks 406 drive the cleaning brush 403 to move away from the limiting groove 404 until the auxiliary block 406 slides out of the inner wall of the limiting groove 404. Then, the operator continues to move away from the limiting groove 404 to make the cleaning brush 403 slide out of the arc surface of the piston 7. At this time, the operator can replace a new cleaning brush 403. The several limiting blocks 405 on the side of the fixing ring 402 away from the connecting column 5 can limit the auxiliary block 406 and facilitate the operator to slide the auxiliary block 406 into the inner wall of the limiting groove 404.
