[0006] To solve the above technical problems, according to one aspect of the utility model, more specifically, a new type of folding painting stand comprises a stand, a cross bar is commonly fixed above the opposing surfaces of the two stands, a support rod is rotatably connected above the rear side surface of the stand, a front connecting rod is commonly fixed below the opposing surfaces of the two stands, a rear connecting rod is commonly fixed below the opposing surfaces of the two support rods, an adjustment device is provided between the front connecting rod and the rear connecting rod, a slide groove is opened in the middle of the front side surface of the stand, and a fixing device is provided in front of the slide groove.

[0007] Furthermore, the adjusting device includes a connecting column, the rear end of which is rotatably connected to a first threaded rod, the front end of the connecting column is rotatably connected to the middle part of the rear side surface of the front connecting rod, the middle part of the front side surface of the rear connecting rod is rotatably connected to a connecting block, the front end of the connecting block is rotatably connected to an adjusting tube, the rear of the first threaded rod is screwed to the inside of the adjusting tube, and a limiting block is fixed behind the upper outer wall of the connecting column.

[0008] The lockhole that is formed on the upper and lower surfaces of the fixing plate is formed on the fixing plate, and the fixing plate has the lockhole that is formed on the upper and lower surfaces of the fixing plate.

[0009] Furthermore, the rear of the bottom of the limiting block contacts the upper part of the front outer wall of the first threaded rod.

[0010] Furthermore, the inner wall of the guide tube fits with the outer wall of the bracket.

[0011] The utility model provides a novel foldable painting stand with the following beneficial effects: the painting stand can be folded by pulling the limit block upwards and closing the stand and the support rod at the same time; when unfolding, the limit block can be pressed downwards and the stand and the support rod can be separated at the same time to unfold the painting stand; the drawing board is fixed in the middle of the fixing device, the adjusting tube is rotated to make the first threaded rod move forward and backward; the movement of the first threaded rod changes the distance between the connecting column and the adjusting tube, changes the length of the adjusting device, thereby changing the angle of the stand to achieve the effect of adjusting the angle of the drawing board; when fixing the drawing board, the bottom and top of the drawing board are respectively inserted into the lower card slot and the upper card slot, the rotating block is rotated to drive the second threaded rod to rotate, and under the action of the slider, the slide groove, the guide block and the guide hole, the lower fixing plate moves upward, the distance between the upper fixing plate and the lower fixing plate is shortened to fix the drawing board, the bolt is loosened to move the guide tube up and down to adjust the height of the drawing board according to the needs of the user, and the position of the drawing board can be fixed by tightening the bolt after the height adjustment of the drawing board is completed.
