Detailed Embodiment

[0020] 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 the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-3, the present utility model provides a technical solution: a replaceable-tip paintbrush, which includes a paintbrush rod 1. Below the paintbrush rod 1, there is a paintbrush tip 6. The top of the paintbrush tip 6 is fixedly connected with a clamping block 9. Inside the paintbrush rod 1, there is a clamping groove 18 that cooperates with the clamping block 9. Inside the paintbrush rod 1 and above the clamping groove 18, there are a first sliding groove 2 and a fifth sliding groove 20. Inside the first sliding groove 2, there is a baffle 4 slidingly connected. Inside the fifth sliding groove 20, there is a moving block 10 slidingly connected. The top of the moving block 10 is fixedly connected with a first spring 12, and the moving block 10 is fixedly connected with the baffle 4. The user pushes the baffle 4 upward to expose the square groove 17. The baffle 4 drives the moving block 10 to squeeze the first spring 12 and move. The user presses the push block 11 to move. The push block 11 squeezes the second spring 15. The push block 11 drives the second limiting plate 8 away from the clamping block 9, enabling the paintbrush rod 1 to be quickly installed and disassembled from the paintbrush tip 6, with simple operation.

[0022] Furthermore, the top of the paintbrush tip 6 is equidistantly fixedly connected with first limiting plates 5. Inside the paintbrush rod 1, there are first limiting grooves 14 that cooperate with the first limiting plates 5. When installing the paintbrush tip 6, the paintbrush rod 1 is pushed into contact with the paintbrush tip 6, and the first limiting plates 5 enter the inside of the first limiting grooves 14, improving the connection stability between the push block 11 and the paintbrush tip 6, preventing the paintbrush tip 6 from rotating during use, and ensuring the use effect of the painting brush.

[0023] Furthermore, inside the paintbrush rod 1, there are a third sliding groove 19 and a square groove 17. Inside the third sliding groove 19, there is a second limiting plate 8 that slides and is used in cooperation with the clamping block 9. The paintbrush tip 6 pushes the clamping block 9 to squeeze the second limiting plate 8 into the inside of the clamping groove 18. The push block 11 drives the second limiting plate 8 to move under the elastic force of the second spring 15, facilitating the limiting of the clamping block 9.

[0024] Furthermore, inside the paintbrush rod 1, there is a second sliding groove 13. Inside the second sliding groove 13, there is a push block 11 slidingly connected. The push block 11 is fixedly connected with the second limiting plate 8. One side of the push block 11 is fixedly connected with a second spring 15. The user presses the push block 11 to move. The push block 11 squeezes the second spring 15. The push block 11 drives the second limiting plate 8 away from the clamping block 9.

[0025] Furthermore, inside the push block 11, there is a second limiting groove 16. Inside the second limiting groove 16, there is a second limiting rod 7 slidingly connected. The second limiting rod 7 is fixedly connected with the paintbrush rod 1, facilitating the limiting of the push block 11 and preventing the push block 11 from shifting during movement.

[0026] Furthermore, a first limiting rod 3 is fixedly connected inside the fifth sliding groove 20, and a moving block 10 is slidably connected to the outer side of the first limiting rod 3, which facilitates the limiting of the moving block 10 and prevents the moving block 10 from shifting during movement.

[0027] During operation, when installing the paintbrush tip 6, the paintbrush rod 1 is pushed into contact with the paintbrush tip 6. The first limiting plate 5 enters the inside of the first limiting groove 14, improving the connection stability between the pushing block 11 and the paintbrush tip 6, so that the paintbrush tip 6 will not rotate during use, ensuring the use effect of the painting brush. At the same time, the paintbrush tip 6 pushes the clamping block 9 to squeeze the second limiting plate 8 into the inside of the clamping groove 18. The pushing block 11 drives the second limiting plate 8 to move under the elastic force of the second spring 15, facilitating the limiting of the clamping block 9, and enabling the quick installation and connection of the paintbrush rod 1 and the paintbrush tip 6. When replacing the paintbrush tip 6, the user pushes the baffle 4 upward to expose the square groove 17. The baffle 4 drives the moving block 10 to squeeze the first spring 12 to move. The user presses the pushing block 11 to move. The pushing block 11 squeezes the second spring 15. The pushing block 11 drives the second limiting plate 8 away from the clamping block 9, enabling the quick installation and disassembly of the paintbrush rod 1 and the paintbrush tip 6. After the disassembly is completed, the baffle 4 is released. The moving block 10 drives the baffle 4 to return to its original position under the elastic force of the first spring 12 to block the square groove 17, avoiding the accidental pressing of the pushing block 11 from causing the loosening of the connection between the paintbrush rod 1 and the paintbrush tip 6. The operation is simple, improving the practicability of the device.
