[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1-8, an interior decoration wall smoothing device, including a housing 1. A rotating rod 2 is rotatably arranged inside the housing 1. A gear 3 is fixedly arranged on the surface of the rotating rod 2. A telescopic component is arranged inside the gear 3. The gear 3 is provided with a support frame 7 through the telescopic component. The telescopic component includes a rack 4 meshed inside the gear 3. One end of the rack 4 is fixedly provided with a telescopic arm 5. Limiting strips one 6 are fixedly arranged on both the left and right sides of the telescopic arm 5. The surfaces of the rack 4, the telescopic arm 5, and the limiting strips one 6 are all lapped with the inner wall of the housing 1. The telescopic arm 5 is limited by the limiting strips one 6, preventing the telescopic arm 5 from sliding out of the housing 1. A brush roller 8 is lapped inside the support frame 7. A connecting frame 9 is fixedly arranged on the right side of the housing 1. The inner wall of the connecting frame 9 is rotatably arranged with the surface of the rotating rod 2. A limiting component is arranged on the surface of the connecting frame 9. The connecting frame 9 is provided with a moving sleeve 12 through the limiting component. The limiting component includes a chute 10 opened on the surface of the connecting frame 9. A limiting strip two 11 is slidably arranged inside the chute 10, and the surface of the limiting strip two 11 is fixedly arranged with the inner wall of the moving sleeve 12. Through the arrangement of the chute 10 and the connecting frame 9, it is convenient to limit the handle 14 after the insertion block 13 is inserted into the handle 14, avoiding the situation that it rotates automatically and causes the brush roller 8 to fall off. A plug-in locking component is arranged on the surface of the moving sleeve 12. The plug-in locking component includes an insertion block 13 fixedly arranged on the right side of the moving sleeve 12. The number of the insertion blocks 13 is several. The several insertion blocks 13 are arranged in a circular array, and the several insertion blocks 13 are all made of metal material, ensuring the stability of the connection between the insertion block 13 and the handle 14. The surface of the insertion block 13 is lapped with the handle 14. The left side of the handle 14 is lapped with the right side of the moving sleeve 12. The left side of the handle 14 is fixedly arranged with one end of the rotating rod 2. The inner wall of the handle 14 is rotatably arranged with the surface of the connecting frame 9. By rotatably connecting the handle 14 with the connecting frame 9, the situation that the rotating rod 2 is bent and deformed due to uneven force is avoided. A screwing component is arranged on the surface of the moving sleeve 12. The screwing component includes an internal thread sleeve 15 rotatably arranged on the surface of the moving sleeve 12. An external thread sleeve 16 is threadedly arranged inside the internal thread sleeve 15, and the inner wall of the external thread sleeve 16 is fixedly arranged with the surface of the connecting frame 9. Through the cooperation of the internal thread sleeve 15 and the external thread sleeve 16, the situation that the insertion block 13 automatically slides out of the handle 14 is avoided. For this interior decoration wall smoothing device, by rotating the handle 14, the handle 14 drives the rotating rod 2, the rotating rod 2 drives the gear 3 to rotate, so that the telescopic component drives the support frames 7 to move away from each other, thereby enabling the brush roller 8 to automatically disengage from the support frame 7, and the brush roller 8 can be removed without the hand contacting the used brush roller 8. After the replacement is completed, by rotating the internal thread sleeve 15, the moving sleeve 12 drives the insertion block 13 to be inserted into the handle 14, avoiding the situation that the handle 14 rotates automatically, and solving the problem that when replacing the brush roller 8 of the existing interior decoration wall smoothing device, the user needs to manually hold the used brush roller 8 to remove it, which is extremely likely to cause the paint to stick to the skin surface and clothes.It prevents the paint from sticking to clothes and skin, which is not only difficult to clean but also adverse to the health of users. Moreover, it is convenient to adjust and adapt according to the length of the brush roller 8, making it easy to use.

[0025] When in use: When the brush roller 8 needs to be replaced, just rotate the internal thread sleeve 15 so that the internal thread sleeve 15 moves towards the side of the brush roller 8. At the same time, the internal thread sleeve 15 drives the moving sleeve 12 to move towards the side of the brush roller 8. During the movement of the moving sleeve 12, the limiting strip II 11 and the insertion block 13 are driven to move synchronously. When the insertion block 13 moves out of the inner wall of the grip 14, the grip 14 can be rotated, so that the grip 14 drives the rotating rod 2 to rotate. As a result, the rotating rod 2 drives the gear 3 to rotate, and the gear 3 drives the two racks 4 to move towards the front and rear sides respectively. During the movement of the racks 4, the two telescopic arms 5 are driven to move away from each other, so that the telescopic arms 5 drive the support frame 7 to move away from each other, and then the support frame 7 can be separated from the lap joint with the brush roller 8, and the brush roller 8 can be removed for replacement. When installing, just rotate the grip 14 in the reverse direction to make the rotating rod 2 rotate in the reverse direction, so that the two support frames 7 move closer to clamp the brush roller 8. Finally, rotate the internal thread sleeve 15 in the reverse direction so that the insertion block 13 moves to the right and re-inserts into the inside of the grip 14.
