Detailed ways

In order to further explain the technical means and effects of the utility model to achieve the predetermined utility model purpose, the following will be combined with the preferred embodiment and the accompanying drawings to describe the auxiliary assembly for a drawing auxiliary tool proposed according to the utility model, its specific implementation, structure, features and efficacy, as follows in detail.

When drawing, the side of the backing plate facing the drafter is defined as the front, and the side facing away from the drafter is defined as the rear. Please refer to Fig. 1-Fig. 4, an auxiliary assembly for a drawing auxiliary tool, including a support plate 1, three legs 2 connected to the bottom of the support plate 1, a backing plate 3 connected to the top of the support plate 1 through a rotating shaft, and an adjustment plate 16 connected to the rear side of the support plate 3 through a hinge; Two moving holes 6 communicated with the movable groove 5, two stroke rods 9 are arranged symmetrically in the movable groove 5, and each stroke rod is fixedly connected with the bottom of the movable groove and the top of the movable groove respectively. Under the drive of the slider, the movable splint is close to the fixed splint to clamp the drawing boards of different sizes, or the movable splint is away from the fixed splint so that the painter can replace or take down the drawing board. The connecting plate 702 is provided with a nut used in conjunction with the screw mandrel. The end is affixed to the rotating disk 15 and the rotating disk is positioned at the rear side of the leaning plate. The fixed shell 4 with an inner chamber communicated with the movable groove 5 is provided on the leaning plate 3 rear side. The rotating rod 14 passes through the fixed shell 4.

Further, when the auxiliary assembly is in use, the outriggers can be opened; when the auxiliary assembly is not in use, the outriggers can be folded, which facilitates the carrying of the auxiliary assembly. The means for realizing the opening and folding of the legs is an existing mature technology, which will not be described in detail here.

Furthermore, the support plate 1 is a T-shaped plate, which reduces the use of materials while ensuring that the support plate 1 can support the upper parts, reduces the cost and also reduces the use of space.

Further, the support plate 1 is located on the top of the rear side of the backing plate 3, and 15 adjustment slots 17 are evenly distributed in conjunction with the adjustment plate 16. When the angle of the backing plate 3 needs to be adjusted, the adjustment plate 16 is rotated by a certain angle and inserted into the adjustment slot 17 at a suitable position.

Further, the movable splint 10 and the fixed splint 11 are both L-shaped plates, and the drawing board can be initially positioned by means of the retaining edge, which is convenient for subsequent clamping and positioning; in addition, the movable splint 10 and the fixed splint 11 are used to contact the surface of the drawing board.

Further, the turntable 15 is provided with a force application part (in this embodiment, a plurality of force application protrusions uniformly distributed along the circumferential direction) for use in cooperation with the palm, so that no slippage will occur when the turntable 15 is rotated with the palm.

Further, the fixed shell 4 is positioned at the top of the connection between the back plate 3 and the adjustment plate 16, so that the turntable 15 can be rotated without lifting the adjustment plate 16;

Further, when the screw rod 701 drives the connecting plate 702 and then drives the slider 703 to move up and down, the stroke hole 8 and the stroke rod 9 can control the moving position of the slider 703, so that the slider 703 will not move when it moves.
