DETAILED DESCRIPTION

[0020] The utility model embodiment provides a portable outdoor drawing board, as Figures 1-3 As shown in the figure, including drawing board body 11, brush receiving cavity 12, brush clamp 13, handle 14, second cavity 15, first sleeve 16, elastic member 17, sliding pivot 18, first support rod 19, second support rod 20, third support rod 21, rotating groove 22, second pivot 23, first connecting rod 24, base rod 25, second opening 26, bolt 27, pad 28.

[0021] As Figures 1-2As shown, the handle 14 is fixedly connected to one end of the drawing board body 11, second cavities 15 are formed on both sides of the drawing board body 11, first sleeves 16 are fixedly connected in the second cavities 15, sliding shafts 18 are slidingly connected in the first sleeves 16, support assemblies are fixedly connected to one end of the sliding shaft 18 away from the first sleeve 16, the support assemblies comprise first support rods 19, second support rods 20 and third support rods 21, one end of the first support rod 19 is fixedly connected to the sliding shaft 18, the other end of the first support rod 19 is fixedly connected to the second support rod 20, and the second support rod 20 is slidingly connected with the third support rod 21.

[0022] It is worth noting that elastic members 17 can be arranged in the first sleeves 16, one end of the elastic member 17 is fixedly connected to an end wall of the inner cavity of the first sleeve 16, and the other end of the elastic member 17 is fixedly connected to the sliding shaft 18.

[0023] A pad 28 is fixedly connected to the end face of the drawing board body 11 away from the handle 14, the pad 28 is made of rubber material, two brush storage cavities 12 are formed on the end face of the drawing board body 11 close to the handle 14, and brush clamps 13 are fixedly connected in the brush storage cavities 12.

[0024] A rotating groove 22 is formed on one end of the third support rod 21 away from the first support rod 19, a second shaft 23 is rotatably connected in the rotating groove 22, first connecting rods 24 are fixedly connected to both ends of the second shaft 23, a base rod 25 is fixedly connected between the two first connecting rods 24, a torsional spring is sleeved on the outer circumferal face of the second shaft 23, and the torsional spring is fixedly connected with a side wall of the rotating groove 22.
