The auxiliary moving component is connected to the fixed block 201 through the sealing adjustment component, and moves under the drive of the auxiliary moving component to seal the opening on the fixed block 201 to prevent the convex block 203 from falling off the fixed block 201, and the sealing adjustment component is limited by the limiting fixing component installed on the sealing adjustment component.

[0034] It should be noted that a convex groove 202 for the convex block 203 to slide against is provided on one side of the fixed block 201 close to the scraper body 3 , and the opening of the convex groove 202 faces the sealing adjustment assembly, in order to facilitate replacement of the scraper body 3 .

[0035] It is understandable that a groove 204 for installing a sealing adjustment component is provided on the side of the fixing block 201 away from the handle 1 in order to facilitate sealing of the opening on the convex groove 202 and prevent the convex block 203 from falling off the fixing block 201 .

[0036] In addition, the sealing adjustment assembly includes a sealing plate 2051, a moving block 2052, a sliding rod 2053 and a No. 1 spring 2054; there are two sliding rods 2053, and the two ends of the sliding rod 2053 are respectively connected to the inner wall of the groove 204, the moving block 2052 is slidably connected between the outer sides of the two sliding rods 2053, and the sealing plate 2051 is connected to the sliding rod 2053 through the moving block 2052, the moving block 2052 moves with the sealing plate 2051, and the No. 1 spring 2054 is sleeved on the outer side of the sliding rod 2053, in order to improve the disassembly and assembly efficiency of the scraper body 3 and reduce the time of using tools to disassemble the scraper body 3.

[0037] In this embodiment, the auxiliary moving component includes an arc-shaped push plate 2061 and an arc-shaped anti-slip pad 2062; one side of the arc-shaped push plate 2061 is fixedly connected to the sealing plate 2051, and the sealing plate 2051 is pushed to move under the drive of the arc-shaped push plate 2061, and the other side is fixedly connected to the arc-shaped anti-slip pad 2062. This is to increase the friction between the user's fingers and the arc-shaped anti-slip pad 2062, so as to facilitate the user to push the sealing plate 2051 to move.

[0038] It should also be noted that the limiting and fixing assembly includes an adjustment box 2071, an insertion rod 2072 and a handle 2073; the side of the adjustment box 2071 away from the handle 2073 is fixedly connected to the sealing plate 2051, one end of the insertion rod 2072 is fixedly connected to the handle 2073, and the other end passes through the adjustment box 2071 and the sealing plate 2051 in sequence and is connected to the fixed block 201, and moves under the pull of the handle 2073 in order to limit the left and right movement of the sealing plate 2051.

[0039] It should also be understood that a slot 209 for the insertion rod 2072 to fit into is provided on one side of the fixing block 201 close to the sealing plate 2051 , so that the insertion rod 2072 can be tightly inserted into the slot 209 to limit the movement of the sealing plate 2051 .

[0041] The working principle of the above embodiment is:

[0042] When the scraper body 3 needs to be replaced, first pinch the pull handle 2073 with two fingers and pull it in the direction away from the sealing plate 2051. Under the limiting action of the limit block 2082, the insertion rod 2072 is driven to move in the direction away from the slot 209. Under the squeezing force of the limit block 2082, the second spring 2081 is continuously elastically contracted. When the insertion rod 2072 is separated from the slot 209 and the restriction on the sealing plate 2051 is released, at this time, the fingers of the other hand are tightly attached to the arc-shaped anti-slip pad 2062 and pushed in the direction away from the scraper body 3, driving the sealing plate 2051 to move away from the scraper The blade body 3 moves in the direction of the handle 1. Since the moving block 2052 can only move in the groove 204 due to the sliding connection with the sliding rod 2053, the moving block 2052 moves stably left and right on the outside of the sliding rod 2053 under the thrust of the sealing plate 2051, and continuously squeezes the spring 2054. When the sealing plate 2051 is removed from the opening of the convex groove 202, the scraper body 3 is pulled away from the handle 1, and the scraper body 3 can be removed from the fixed block 201. The structure is simple and the operation is convenient, which improves the disassembly and assembly efficiency of the scraper body 3.

[0043] Compared with the prior art: the scraper for cleaning the inner wall of the cylinder, through the mutual cooperation between the convenient disassembly and assembly mechanism 200 on the handle 1 and the scraper body 3, can provide a function of conveniently replacing the scraper body 3, so that the scraper body 3 and the handle 1 can be separated from each other, the structure is simple and the operation is convenient, the disassembly and assembly efficiency of the scraper body 3 is improved, the time for using tools to disassemble the scraper body 3 is reduced, and the difficulty of disassembly is reduced, thereby effectively improving the use effect of the existing scraper and solving the problem of poor use effect of the existing scraper.
