[0018] 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. The following describes the specific implementation of the present utility model in detail in conjunction with specific embodiments.

[0019] As Figures 1-4 shown, a telescopic paint brushing tool includes a telescopic rod 1 and a roller brush head 3 installed on the telescopic rod 1. The telescopic rod 1 at least includes a first sleeve 2 and a second sleeve 12. The second sleeve 12 is sleeved outside the first sleeve 2. According to the length requirement of the telescopic rod 1, it may further include a third sleeve. The third sleeve is sleeved outside the second sleeve 12 to further increase the length of the telescopic rod 1. The first sleeve 2, the second sleeve 12, and the third sleeve are all hollow tubes.

[0020] A rotation resistance member 2 is provided in the first sleeve 2. The rotation resistance member 2 is made of an elastic metal material and includes an arc-shaped snap ring 21, a clamping member 22 fixedly installed on the snap ring 21, and a guide block 23 provided on the outer side of the snap ring 21. There are three clamping members 22. The upper end of the clamping member 22 is provided with an inwardly bent inner folding portion and an outwardly bent outer folding portion, and both the inner folding portion and the outer folding portion are rounded.

[0021] A ring-shaped rotation groove 111 is provided at a lower position of the first sleeve 2. Above the rotation groove 111, a sliding groove 113 and a guiding inclined surface 112 connected to the sliding groove 113 are provided. The sliding groove 113 and the rotation groove 111 are coaxially arranged with the first sleeve 2, and the sliding groove 113 and the rotation groove 111 have the same radius. The guiding inclined surface 112 connects the sliding groove 113 and the outer wall of the first sleeve 2. The snap ring 21 is clamped in the rotation groove 111 and can slide in the rotation groove 111 with the first sleeve 2 as the axis. The clamping member 22 is placed at the sliding groove 113 and the guiding inclined surface, and the inner folding portion abuts against the first sleeve 2. On the inner wall of the second sleeve 12, a guide rail is arranged along the axial direction. The guide rail can be a groove provided in the inner wall or two convex rails provided on the inner wall. The guide block 23 is clamped in the guide rail. When the clamping member 22 is placed in the sliding groove 113, the first sleeve 2 and the second sleeve rod can freely expand and contract, and the extended length of the telescopic rod 1 can be adjusted. When the extended length needs to be fixed, the first sleeve 2 is rotated. The guide block 23 clamped in the guide rail makes the second sleeve 12 drive the rotation resistance member 2 to rotate. The clamping member 22 moves from the guide groove 121 to the guiding inclined surface 112, and the inner folding portion abuts against the outer wall of the first sleeve 2. When rotating to the guiding inclined surface 112, the outer folding portion gradually abuts against the inner wall of the second sleeve 12. The clamping member 22 is clamped between the guiding inclined surface 112 and the inner wall of the second sleeve 12, increasing the friction force between the first sleeve 2 and the second sleeve 12, clamping the telescopic rod 1 tightly, and fixing the extended length of the telescopic rod 1. Only a small rotation angle is required to clamp the first sleeve 2 and the second sleeve 12 tightly, and the extended length of the telescopic rod 1 can be flexibly adjusted. By using three clamping members 22 and three guiding inclined surfaces, even if one clamping member 22 is broken, the rotation resistance member 2 can still ensure the fixing effect of the telescopic rod 1.

[0022] Above the guiding groove 121 and the guiding inclined surface 112, a convex ring 114 is provided. On the inner wall of the upper part of the second sleeve 12, a retaining ring 122 is provided. The inner diameter of the retaining ring 122 is greater than the outer diameter of the first sleeve 2 and less than the outer diameter of the convex ring 114. When extending upward, the retaining ring 122 blocks the upward movement of the convex ring 114 and limits the extending distance of the first sleeve 2. A sleeve 13 is provided at the upper end of the first sleeve 2. The sleeve 13 is fastened to the outer surface of the first sleeve 2. The bottom of the sleeve 13 abuts against the second sleeve 12. Anti-slip threads 131 are provided on the sleeve 13, and external threads are provided at the top of the sleeve 13. Relative displacement can be generated between the first sleeve 2 and the second sleeve 12 by rotating the sleeve 13, and the rotation resistance member 2 can be clamped between the first sleeve 2 and the second sleeve 12.

[0023] The rolling brush head 3 is threadedly connected to the sleeve 13. The rolling brush head 3 includes a connecting rod 31 and a hair roller 32 rotatably connected to the connecting rod 31. The connecting rod 31 is inclined forward. There are two hair rollers 32, and the two hair rollers 32 are arranged in parallel. Usually, multiple coatings are required to ensure the coating effect during painting. With the double hair roller 32 structure, the two hair rollers 32 are used together during painting, and two coats can be applied at one time, improving the painting efficiency.

[0024] When a third sleeve is sleeved outside the second sleeve 12, the second sleeve 12 and the third sleeve are clamped by installing the rotation resistance member 2 in the second sleeve 12. The structure is the same as the above structure and will not be described in detail here.

[0025] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution content of the present invention still fall within the protection scope of the technical solution of the present invention.
