The cleaning tube 71 is in contact with the surface of the sandpaper tube 8 through the cleaning bristles 72 on the inner wall, which facilitates the cleaning of the surface of the sandpaper tube 8. At the same time, when the cleaning tube 71 moves, the cleaning tube 71 drives the first guide tube 43 and the second guide tube 44 to slide and extend, ensuring that the cleaning tube 71 moves along the axis of the sandpaper stick 2. The cleaning operation is simple. The operator does not need to find tools. He can directly operate the cleaning mechanism to clean the surface of the sandpaper tube 8, ensuring that the surface of the sandpaper tube 8 is clean. The operation is simple and improves the overall practicality of the sandpaper stick 2.

[0048] The anti-slip sleeve 3 is fixedly fitted onto the surface of the handle 1, and a number of anti-slip strips are evenly distributed in a ring on the outer surface of the anti-slip sleeve 3.

[0049] Increase the friction between the user and the handle 1 to ensure the stability of the user's hand.

[0050] The number of fixing holes 21 is several, and the fixing holes 21 are equally distributed among each other, and the fixing holes 21 penetrate the surface of the sandpaper rod 2.

[0051] The fixing mechanism 6 includes a connecting ring 61, a fixing plate 62, a fixing post 63, a fixing nut 64, and a threaded sleeve 65. The connecting ring 61 is sleeved on the surface of the sandpaper rod 2. The fixing plate 62 is attached to the front surface of the connecting ring 61. The fixing post 63 is fixedly connected to the rear side of the fixing plate 62. The fixing nut 64 is sleeved at the end of the fixing post 63. The threaded sleeve 65 is threaded onto the surface of the sandpaper rod 2.

[0052] The length of the sandpaper tube 8 allows for easy adjustment of the position of the connecting ring 61, facilitating the penetration of the fixing post 63, which is mounted on the side surface of the connecting ring 61, through the corresponding fixing hole 21. By rotating the fixing nut 64, the connecting ring 61 can be easily fixed to the sandpaper stick 2. Then, the sandpaper tube 8 is fitted onto the surface of the sandpaper stick 2. By rotating the threaded sleeve 65, the sandpaper tube 8 can be clamped and fixed with the cooperation of the connecting ring 61, facilitating the grinding operation. By disassembling the threaded sleeve 65, the sandpaper tube 8 can be easily replaced. The operation is simple and reduces the workload of the user.

[0053] The top end of the sandpaper tube 8 is in contact with the bottom surface of the threaded sleeve 65, and the bottom end of the sandpaper tube 8 is in contact with the top side surface of the connecting ring 61.
