A fixed support leg 2 is rotatably connected to the surface of the support 1. A protrusion is provided on one side of the fixed support leg 2. A mating support leg 3 is rotatably connected to the surface of the support 1. A positioning rod 4 is slidably connected inside the support 1. A positioning strip is provided on the surface of the positioning rod 4. A positioning hole is opened on the surface of the fixed support leg 2, and the positioning strip is rotatably connected to the positioning hole. A connecting strip is provided on the surface of the positioning rod 4. A connecting hole is opened on the surface of the mating support leg 3, and the connecting strip is rotatably connected to the connecting hole. A fixed support is fixedly connected inside the positioning rod 4. Spring 5, fixed clamping plate 6 is fixedly connected to the upper surface of fixed spring 5, positioning rod 4 has a positioning groove inside, positioning rod 4 is slidably connected to fixed clamping plate 6 through positioning groove, fixing bolt 7 passes through the internal thread of fixed leg 2, fixing seat 8 passes through the fixed leg 2 through fixing bolt 7 thread, fixing seat 8 has a C-shaped groove inside, fixing seat 8 is slidably connected to fixed leg 2 through C-shaped groove, fixing rod 9 is inserted into fixing seat 8, docking seat 10 is sleeved on the surface of fixing rod 9, placing frame 11 is slidably connected to the surface of docking seat 10, one side of placing frame 11 is fixed A drive base 12 is fixedly connected, and a docking rod 13 is inserted into the drive base 12. A connecting seat 14 is sleeved on the surface of the docking rod 13. A collection box 15 is fixedly connected to one side of the connecting seat 14. A moving rod 16 is fixedly connected inside the collection box 15. A moving spring 17 is sleeved on the surface of the moving rod 16. A moving plate 18 is fixedly connected to the lower surface of the moving spring 17. A collection groove is opened inside the collection box 15, and the collection box 15 is slidably connected to the moving plate 18 through the collection groove. A support assembly 19 is fixedly connected to the lower surface of the placement rack 11. The fixed support legs 2 are arranged from top to bottom as follows: Multiple threaded holes are provided, and the size of each threaded hole is adapted to the size of the fixing bolt 7. There are two support groups 19, which are located on the lower surface of the placement frame 11 near both sides. Each support group 19 includes a support shaft seat 901, a support seat 902, a support rod 903, an auxiliary rod 904, and a nut 905. The support seat 902 is rotatably connected inside the support shaft seat 901. The support rod 903 is fixedly connected to one side of the support seat 902. The auxiliary rod 904 is slidably connected inside the support rod 903. The nut 905 is threaded through the surface of the support rod 903.

[0038] By moving the positioning rod 4 downwards to unfold the fixed support leg 2 and the docking support leg 3, the bracket 1 can be fixed. By sliding the fixed seat 8 up and down until the fixed seat 8 is moved to a suitable height, the fixing bolt 7 is tightened so that it passes through the fixed seat 8 and the fixed support leg 2, thus fixing the placement rack 11. Then, the paint tray is placed on the placement rack 11. By pulling out the fixing rod 9 on one side, the placement rack 11 and the paint tray can be rotated using the fixing rod 9 on the other side until they are rotated to a suitable position. At the same time, by rotating the support base 902, the auxiliary rod 904 is aligned with the ground. The surface is vertical. Then, by moving the auxiliary rod 904 downwards to make it contact the ground, and then tightening the nut 905, the auxiliary rod 904 is fixed to support the placement frame 11. This reduces the need for users to hold the paint tray when painting on the easel. Holding the paint tray is not only inconvenient for mixing paints, but also affects the user's normal painting. The goal is to allow users to place the paint tray by fixing the placement frame 11 to the fixed support leg 2 when painting on the easel, thereby freeing the user's hands and enabling them to better create paintings.

[0039] By tearing drawing paper into small pieces, or tearing blank parts of failed painting waste paper into small pieces, and placing the torn pieces between the moving plate 18 and the collection box 15 by moving the moving plate 18 upwards, and releasing pressure by moving spring 17, the moving plate 18 moves downwards to press and fix the small pieces of drawing paper. After mixing paint, users can test the paint color on the small pieces of drawing paper. The small pieces of drawing paper near the top can be discarded after use. Then, the remaining small pieces of drawing paper can be used to test the paint. This reduces the need for users to test the mixed paint after mixing. Testing on the painting paper can easily contaminate the artwork, and testing on the paint tray can cause slight color differences due to the different materials of the paint tray and the drawing paper, affecting the accuracy of the mixed paint. This achieves the effect of users achieving the desired color by using small pieces of drawing paper to test the mixed paint after mixing.

[0040] like Figure 7 and Figure 8As shown, a drawing board 20 is snapped into the inside of the fixed clamping plate 6. A spring telescopic rod 21 is fixedly connected to one side of the drawing board 20. A limit rod 22 is fixedly connected to one side of the spring telescopic rod 21. An auxiliary clamp 23 is fixedly connected to one end of the limit rod 22. An auxiliary sliding groove is provided inside the drawing board 20. The drawing board 20 is slidably connected to the auxiliary clamp 23 through the auxiliary sliding groove. A placement shaft seat 24 is snapped into one side of the fixed clamping plate 6. A placement seat 25 is rotatably connected inside the placement shaft seat 24. A placement rod 26 is fixedly connected to one side of the placement seat 25. An extension rod 27 is slidably connected inside the placement rod 26. A lamp holder 28 is fixedly connected to one side of the extension rod 27. The extension rod 27 is located near the middle of one side of the lamp holder 28. A lighting lamp 29 is fixedly connected inside the lamp holder 28.

[0041] By moving the fixed clamp 6 upwards, the drawing board 20 is secured by the fixed clamp 6. Then, the fixed clamp 6 is moved downwards by the fixed spring 5, so that the fixed clamp 6 and the protrusion clamp the drawing board 20 tightly and securely. By moving the limiting rod 22 toward the drawing board 20, the spring telescopic rod 21 is retracted. By placing the drawing between the drawing board 20 and the auxiliary clamp 23, the pressure is released by the spring telescopic rod 21, so that the limiting rod 22 is reset. Thus, the drawing board 20 and the auxiliary clamp 23 clamp the drawing tightly and securely. This reduces the need to use clamps and other tools to fix the drawing on the drawing board 20, which usually requires multiple clamps and is time-consuming and laborious for users. The drawing can be fixed simply by pressing the limiting rod 22, placing the drawing on the drawing board 20, and then releasing the limiting rod 22.

[0042] By fixing the mounting bracket 24 to one side of the fixing clamp 6, rotating the mounting rod 26 until the lighting lamp 29 is rotated to a suitable angle, and moving the extension rod 27 until the lighting lamp 29 is moved to a suitable distance, the drawing can be illuminated in low light conditions. This reduces the impact on the user's normal drawing when the light is dim due to weather conditions during outdoor drawing. It achieves the effect of illuminating the drawing with the lighting lamp 29, and the angle and distance of the lighting lamp 29 can be adjusted according to the needs of the user to meet the brightness required for drawing.

[0043] The working principle of this utility model is as follows: First, by moving the positioning rod 4 downward, the fixed support leg 2 and the docking support leg 3 are unfolded. Then, the lower surfaces of the fixed support leg 2 and the docking support leg 3 are brought into contact with the ground, thus fixing the bracket 1 to the ground. By moving the fixed clamping plate 6 upward, the drawing board 20 is clamped in place by the fixed clamping plate 6. Then, by moving the fixed clamping plate 6 downward through the fixed spring 5, the fixed clamping plate 6 and the protrusion clamp the drawing board 20 tightly and fixedly. By moving the limiting rod 22 towards the drawing board 20, the spring telescopic rod 21 is retracted, and the drawing is placed... Between the drawing board 20 and the auxiliary clamp 23, the pressure is released by the spring telescopic rod 21, causing the limit rod 22 to return to its original position. This allows the drawing board 20 and the auxiliary clamp 23 to clamp and fix the drawing. The fixing seat 8 is moved up and down until it reaches a suitable height. The fixing bolt 7 is tightened so that it passes through the fixing seat 8 and the fixing leg 2, thus fixing the placement rack 11. The paint tray is then placed on the placement rack 11. By pulling out the fixing rod 9 on one side, the paint tray can be placed on the other side. The holder 11 and paint tray are rotated until they are in the appropriate position. Simultaneously, the auxiliary rod 904 is made perpendicular to the ground by rotating the support base 902. The auxiliary rod 904 is then moved downwards until it contacts the ground, and the nut 905 is tightened to fix the auxiliary rod 904, thus supporting the holder 11. Drawing paper is torn into small pieces, or blank portions of discarded drawing paper are torn into small pieces. The torn pieces are placed between the moving plate 18 and the collection box 15 by moving the moving spring. Spring 17 releases pressure, causing the moving plate 18 to move downwards and press the small piece of drawing paper firmly in place. This allows users to test the color of the paint on the small piece of drawing paper after mixing the paint. The small piece of drawing paper near the top can be discarded after use. Then, the remaining small piece of drawing paper can be used to test the paint. By fixing the placement shaft 24 to one side of the fixing clamp 6, and by rotating the placement rod 26 until the lighting lamp 29 is rotated to the appropriate angle, and by moving the extension rod 27 until the lighting lamp 29 is moved to the appropriate distance, the drawing can be illuminated in low light conditions.
