[0021] 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.

[0022] Refer to Figures 1 to 8 , the present utility model provides a portable repair paint brushing tool, including a brush handle 1 and a brush head 3. The inner wall of the brush handle 1 is provided with an internal thread 4. Through the setting of the internal thread 4, when the tool is used, it can be fixed together with the bottle repair paint, and the paint liquid in the bottle repair paint can be extruded by extrusion. A paint outlet hole 5 is provided in the middle of the inner cavity of the brush handle 1. When the bottle repair paint is extruded, the paint liquid in the bottle repair paint can be discharged through the paint outlet hole 5.

[0023] The top of the brush handle 1 is connected with a connecting part 2 through a connecting structure. The connecting structure includes a clamping rod 7 threadedly connected to the top of the brush handle 1. The bottom of the connecting part 2 is provided with a slot 13. The clamping rod 7 is movably connected to the inner cavity of the slot 13. A clamping hole is provided in the middle of the clamping rod 7. Clamping blocks 12 adapted to the clamping hole are provided on both sides of the slot 13. Through the setting of the connecting structure, when the clamping rod 7 is clamped with the clamping block 12, the user rotates the connecting part 2, so that the brush handle 1 and the connecting part 2 can be quickly fixed or separated, which is convenient for cleaning the brush handle 1 and the connecting part 2, and the appropriate connecting part 2 can be replaced according to needs during use, improving the adaptability of the tool during use.

[0024] In the middle of the lower end of the connecting part 2, there is a paint inlet hole 11. When the clamping rod 7 is clamped with one clamping block 12, the clamping rod 7 is separated from the other clamping block 12. And when the paint inlet hole 11 overlaps with the paint outlet hole 5, the clamping rod 7 is clamped with one clamping block 12. When the paint inlet hole 11 and the paint outlet hole 5 are staggered, the clamping rod 7 is clamped with the other clamping block 12. The user can move the connecting part 2 to make the paint inlet hole 11 and the paint outlet hole 5 in an overlapping or staggered state.

[0025] In the middle of the inner cavity of the upper end of the connecting part 2, there is a uniformly distributed groove 6 fixedly connected. The inner diameter of the paint inlet hole 11 is the same as that of the paint outlet hole 5. The inner cavity of the uniformly distributed groove 6 is communicated with the inner cavity of the paint outlet hole 5 through the paint inlet hole 11. The size of the paint inlet hole 11 can be set according to requirements and is not limited here. When using this tool and squeezing the bottle repair paint, the paint liquid in the bottle repair paint can enter the paint inlet hole 11 through the paint outlet hole 5, and the paint liquid in the paint inlet hole 11 can enter the uniformly distributed groove 6.

[0026] From the above description, it can be seen that when using this tool, the outflow of the paint liquid can be artificially blocked. The structure formed by the connecting part 2 and the brush handle 1 can be temporarily used as the cap of the bottle repair paint, improving the adaptability of this tool. And the brush handle 1 and the connecting part 2 can be separated. Furthermore, when using this tool, the staff can replace the brush handle 1 or the brush head 3 according to needs, improving the adaptability of this tool.

[0027] The bottom end of the brush head 3 is infiltrated with glue. After the glue solidifies, a fixed end head adapted to the inner cavity of the connecting part 2 is formed at the bottom end of the brush head 3. The brush head 3 is clamped with the inner cavity of the connecting part 2 through the fixed end head. Through the setting of the fixed end head, the brush head 3 and the connecting part 2 can be quickly clamped or separated. There is a uniformly distributed channel 10 in the middle of the fixed end head. The uniformly distributed groove 6 is adapted to the uniformly distributed channel 10. When the brush head 3 is clamped with the connecting part 2, the uniformly distributed groove 6 is inserted into the uniformly distributed channel 10, and the paint liquid in the uniformly distributed groove 6 can flow into the uniformly distributed channel 10, and the paint liquid contacts the bristles of the brush head 3, facilitating the use of this tool to apply the repair paint to the area to be repaired. The glue infiltrated at the bottom end of the brush head 3 can be epoxy resin glue.

[0028] A sealing gasket is fixedly connected to the bottom of the connecting part 2. The material of the sealing gasket can be rubber. Through the setting of the sealing gasket, the sealing performance and friction between the connecting part 2 and the brush handle 1 are increased, avoiding liquid leakage and improving the reliability of the fixed position of the connecting part 2.

[0029] To sum up: When using this portable repair paint brushing tool, the user rotates to open the cap of the bottle repair paint 8, releases the threaded connection state between the cap and the bottle repair paint 8, tears off the sealing film of the paint outlet hole of the bottle repair paint 8, and installs this tool on the bottle repair paint 8 (the bottle repair paint 8 is for pressing or squeezing to discharge. After releasing the pressing on the bottle body, the bottle body rebounds and returns to its original state. The bottle body material of the bottle repair paint 8 can be high-elasticity PE material), as Figure 7As shown, the staff squeezes the bottle-shaped repair paint 8, and the repair paint filled in the bottle-shaped repair paint 8 is extruded. The extruded repair paint enters the uniform distribution channel 10 through the paint outlet hole 5, the paint inlet hole 11 and the uniform distribution groove 6. The repair paint contacts the bristles of the brush head 3. The user uses the brush head 3 to paint the wall surface, and the repair paint can be painted on the repair surface. After the staff releases the pressure on the bottle-shaped repair paint 8, the bottle body of the bottle-shaped repair paint 8 rebounds. When the tool is suspended, the user can move the connecting part 2 until another clamping block 12 is clamped with the clamping rod 7. At this time, the paint outlet hole 5 and the paint inlet hole 11 are in a staggered state, which can prevent the repair paint in the bottle-shaped repair paint 8 from being extruded.
