Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a flexible drawing device, including a drawing table 1. The top and front sides of the drawing table 1 are provided with sliding grooves 3. A protective pad 4 is fixedly connected to the middle of the top of the drawing table 1. A movable ruler 5 is slidably connected to the inner side of the sliding groove 3. A slider 6 is slidably connected to the inner side of the movable ruler 5. A movable plate 7 is rotatably connected to the bottom of the slider 6. A telescopic ruler 8 is slidably connected to the inner side of the movable plate 7. An indicator block 9 is fixedly connected to the rear side of the outer wall of the slider 6. Multiple indicator grooves 10 are provided around the top of the outer wall of the movable plate 7. A positioning mechanism 2 is provided on the outer side of the drawing table 1. The positioning mechanism 2 can be used to fix the drawing paper.

[0031] Specifically, the movement of the movable plate 7 along the slide 3 causes the slider 6 to move. The movement of the slider 6 can drive the movable plate 7 and the telescopic ruler 8 to rotate together. The movement of the telescopic ruler 8 is used to draw the drawing, and the angle of drawing is adjusted by rotating the movable ruler 5, without the need to hold the drawing device.

[0032] Reference Figure 1 , Figure 2 and Figure 3The positioning mechanism 2 includes two first rotating plates 201, which are rotatably connected to the left and right sides of the outer wall of the drawing table 1 respectively. A clamping plate 202 is rotatably connected to the outer side of the first rotating plate 201, and a second rotating plate 203 is rotatably connected to the outer side of the clamping plate 202.

A telescopic plate 204 is slidably connected to the inner side of the clamping plate 202, and a rubber block 205 is fixedly connected to the outer side of the telescopic plate 204.

[0033] Specifically, the rotation of the first rotating plate 201 and the second rotating plate 203 can cause the clamping plate 202 to rotate, thereby fixing the drawing paper placed on the drawing table 1. The telescopic plate 204 on the clamping plate 202 moves along it, driving the rubber blocks 205 to move. These rubber blocks 205 can fix drawing papers of different sizes and shapes through rubber pads.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A dust collection trough 11 is fixedly connected to the rear side of the drawing table 1, and an air pump 12 is fixedly connected to the rear side of the dust collection trough 11.

[0037] Specifically, the reserved slot 21 can improve the stability of the slider 6 when it moves, the controller 18 can control the start-up and operation power between the air pump 12 and the lighting lamp 15 respectively, the housing 19 can improve the protection capability of the controller 18, and the opening and closing cover 20 can prevent the controller 18 from being accidentally touched when it is not in use.

[0038] Working principle: Before using the device, the slider 6 can be moved by moving the moving plate 7 along the slide 3. Moving the slider 6 can drive the moving plate 7 and the telescopic ruler 8 to rotate. Moving the telescopic ruler 8 can draw the drawing, and the drawing angle can be raised by rotating the moving ruler 5, so that there is no need to hold the drawing device to draw.

[0039] The rotation of the first rotating plate 201 and the second rotating plate 203 can drive the clamping plate 202 on them to rotate, so as to fix the drawing paper placed on the drawing table 1. At the same time, along the clamping plate 202 and through the telescopic plate 204, the rubber block 205 on it can be moved, and the rubber block 205 can fix the drawing paper of different specifications and shapes.
