A rectangular slot 4 is provided on the top of the cylinder body 1, and the bottoms of the shell 1 31 and the shell 2 32 are both inserted into the inside of the rectangular slot 4, and the shell 1 31 and the shell 2 32 are fixedly installed with the cylinder body 1 by bolts. The rectangular slot 4 and the bolts are provided to fix the shell 1 31 and the shell 2 32 to the top of the cylinder body 1. The top of the shell 1 31 is fixedly connected The top of the housing 32 is fixedly connected with a fixing sleeve 35, and one end of the inserting plate 36 is inserted into the interior of the fixing sleeve 35. The top of the inserting plate 36 is fixedly connected with a triangular block 1 37, and the interior of the fixing sleeve 35 is provided with a triangular block 2 38. By arranging the triangular block 1 37 and the triangular block 2 38, the inserting plate 36 can be fixed to the interior of the fixing sleeve 35. When the inserting plate 36 is inserted into the fixing sleeve 35, the inclined surface of the triangular block 1 37 will squeeze the inclined surface of the triangular block 2 38. The top of the fixing sleeve 35 is slidably connected with a movable rod 39, and the top of the movable rod 39 is fixedly connected with a pull ring 311. By arranging the pull ring 311, it is convenient to pull the triangular block 2 38. The outer wall of the movable rod 39 is provided with a spring 1 310, and the two ends of the spring 1 310 are respectively fixedly connected to the top of the inner wall of the fixing sleeve 35 and the top of the triangular block 2 38. The triangular block 2 38 can be driven to reset by arranging the spring 1 310.

[0023] Specifically, by arranging shell 1 31 and shell 2 32 outside the piston 2, and making two arc-shaped brush plates 34 surround the piston 2, when the piston 2 is extended or retracted, the bristles in the arc-shaped brush plates 34 can clean the outer wall of the piston 2, thereby achieving the purpose of sweeping off impurities on the outer wall of the piston 2, and preventing impurities from entering the cylinder body 1 and causing contamination of the hydraulic oil.

[0026] The working principle of the present invention is as follows: by arranging the shell 1 31 and the shell 2 32 outside the piston 2, and making the two arc-shaped brush plates 34 surround the piston 2, so that when the piston 2 is extended and retracted, the bristles in the arc-shaped brush plates 34 can clean the outer wall of the piston 2, thereby achieving the purpose of sweeping away impurities on the outer wall of the piston 2 and preventing impurities from entering the cylinder body 1 and causing hydraulic oil pollution. By loosening the bolts fixing the shell 1 31 and the shell 2 32, and then pulling the shell 1 31 and the shell 2 32 out of the rectangular slot 4, and then pulling the pull ring 311 to drive the triangular block 2 38 to separate from the triangular block 1 37, the restriction of the insert plate 36 can be released, thereby separating the shell 1 31 and the shell 2 32, and cleaning the impurities inside the shell 1 31 and the shell 2 32, and when the pull ring 311 drives the triangular block 2 38 to separate from the triangular block 1 37, the spring 2 52 recovers from the compressed state, so that the push plate 51 pushes the insert plate 36, thereby automatically separating the shell 1 31 and the shell 2 32, making it convenient for the staff to clean the impurities.
