Background Art
[0002] When compiling land use plans, a drawing design device is needed to facilitate the drawing of land use plans. When designing a drawing, it is necessary to fix the drawing to ensure the stability of the drawing during tracing. Most of the existing drawing design devices use clips to clamp and fix the paper and the drawing board. The fixing position of the drawing is specified and can only be fixed at a certain part, resulting in that the drawing can only be carried out in a specified area during drawing. When the drawing is smaller than the drawing board, the clip cannot clamp and fix it, and it cannot adapt to the size of the paper, which has certain limitations. Therefore, there is an urgent need for a drawing design device to solve the above-mentioned technical problems.

[0006] The auxiliary positioning clip is parallel to the drawing board. The auxiliary positioning clip comprises a sliding seat, a reference arm, a locking shaft and clamping arms. The reference arm is connected to the sliding seat to change its position as the sliding seat moves. The clamping arms are rotatably connected to the reference arm through the locking shaft, and the clamping arms are rotatably connected to each other through the locking shaft; the rotation of the reference arm and the clamping arms and the mutual rotation of the clamping arms form a paper positioning range.

[0011] Preferably, the clamping arm further includes a third clamping arm, which is hinged to the second clamping arm. The reference arm, the first clamping arm, the second clamping arm and the third clamping arm are bent relative to each other to form a paper positioning range.
[0012] The beneficial effects of the present utility model compared with the background art are as follows:

[0023] Next, in conjunction with the drawings of the specification, by further describing the specific embodiments of the present utility model, the technical solutions and their beneficial effects of the present utility model will be made clearer and more definite. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.
[0024] The preferred embodiments provided by the present utility model are as Figures 1 to 4As shown in the figure, a drawing design auxiliary fixing mechanism includes a drawing board 1 and an auxiliary positioning clamp 2. The drawing board 1 is provided with a chute 11, and the auxiliary positioning clamp 2 is connected to the chute 11 and can move along the chute 11. The chute 11 is arranged at the edge position of the drawing board 1 to keep the end face of the drawing board 1 flat, and the chute 11 is arranged on one side of the drawing board 1.
[0025] The auxiliary positioning clamp 2 is parallel to the drawing board 1. The auxiliary positioning clamp 2 includes a sliding seat 3, a reference arm 4, a locking shaft 5 and clamping arms 6. The reference arm 4 is connected to the sliding seat 3 to change its position as the sliding seat 3 moves. The sliding seat 3 and the chute 11 adopt a conventional slot structure. The sliding seat 3 is provided with a through cavity 31, and the reference arm 4 is inserted into the through cavity 31 and can slide in the through cavity 31 to change the position of the reference arm 4. The reference arm 4 and the sliding seat 3 are fixed by a conventional screw abutment to lock the position of the reference arm on the sliding seat. The clamping arms 6 are rotatably connected to the reference arm 4 through the locking shaft 5, and the clamping arms 6 are rotatably connected to each other through the locking shaft 5. The rotation of the reference arm 4 and the clamping arms 6 and the mutual rotation between the clamping arms 6 form a paper positioning range.
[0026] Both the reference arm 4 and the clamping arms 6 are provided with a number of locking holes 12 and strip-shaped channels 41. The channels penetrate the side of the component where they are located. The auxiliary positioning clamp 2 is equipped with a pressing member 7. The rod portion of the pressing member is provided with threads to screw into the locking holes. The pressing member 7 is screwed into the locking holes. One end of the pressing member 7 in contact with the drawing board 1 is provided with a silicone pressing cap 71. While pressing, it can avoid damaging the drawing. The cross-sectional area of the silicone pressing cap 71 is larger than the diameter of the pressing member 7 to increase the contact area with the paper. The number of the pressing members 7 is determined according to actual needs. The locking shaft 5 passes through the channels 41 and the locking holes 12 to realize the hinge connection between the reference arm 4 and the clamping arms 6 and the hinge connection between the clamping arms 6. Further, the locking shaft 5 adopts a conventional screw, the locking holes 12 are provided with threads, the clamping arms 6 are inserted into the channels of the reference arm 4, and the locking shaft 5 passes through the locking holes 12 of both the clamping arms 6 and the reference arm 4 to hinge the reference arm 4 and the clamping arms 6. The clamping arms 6 are hinged in the channels of the adjacent clamping arms 6 through the locking shaft 5 to enable relative rotation between the clamping arms 6. By changing the angles between the reference arm and the clamping arms and the angles between the clamping arms, the auxiliary positioning clamp can form different-shaped limiting ranges to suit different-shaped papers. At the same time, the channels are strip-shaped, and the components inserted into the channels can move along the channels to change the locking positions of the inserted components to construct the size of the limiting range.
[0027] The clamping arm 6 at least includes a first clamping arm 61 and a second clamping arm 62. The first clamping arm 61 is hinged to the reference arm 4, and the second clamping arm 62 is hinged to the first clamping arm 61. Further, the clamping arm 6 further includes a third clamping arm 63. The first clamping arm 61, the second clamping arm 62, and the third clamping arm 63 are all referential to the number of the clamping arm 6 in this structure, and the three all have the same size and structural features. Three-point positioning can also basically fix the paper, so the first clamping arm 61 and the second clamping arm 62 can be selected. When four-point positioning is required, the third clamping arm 63 is added. The third clamping arm 63 is hinged to the second clamping arm 62, and the reference arm 4, the first clamping arm 61, the second clamping arm 62, and the third clamping arm 63 are bent with each other to form a paper positioning range.
[0028] To solve the problem that the clips of the existing drawing design device cannot adapt to the paper size, this structure proposes a paper auxiliary fixing mechanism, which includes a drawing board 1 and an auxiliary positioning clip 2. The auxiliary positioning clip 2 includes a reference arm 4, a first clamping arm 61, a second clamping arm 62, and a third clamping arm 63 that are hinged to each other, and the positions of the reference arm 4, the first clamping arm 61, the second clamping arm 62, and the third clamping arm 63 can be adjusted by moving relative to each other to change the size of the range formed by the auxiliary positioning clip 2, so that the range formed by the auxiliary positioning clip 2 matches the size of the paper, and it is applicable to a variety of paper sizes. After matching with the paper size, rotate the pressing member 7 to press down the pressing member 7 to abut against the end face of the drawing board 1, and the paper on the drawing board 1 can be fixed.
