[0020] like Figures 1 to 5 As shown, a portable drawing device for engineering construction includes a drawing board 1, both sides of the back side of the drawing board 1 are fixedly connected with a first swivel seat 2, the inside of the first swivel seat 2 is rotatably connected to a swivel rod 3, the surface of the swivel rod 3 is sleeved with an adjustment plate 4, the surface of the adjustment plate 4 is provided with a square groove 5, the inside of the square groove 5 is fixedly connected with a plurality of first limit strips 6, both sides of the top of the back side of the drawing board 1 are fixedly connected with a second swivel seat 7, the inside of the second swivel seat 7 is rotatably connected with a rotating shaft 8, the surface of the rotating shaft 8 is sleeved with a second limit strip 9, the top of the drawing board 1 and the back side of the adjusting plate 4 are fixedly connected with a handle 10, the surface of the left side of the drawing board 1 is provided with a storage groove 11, the inside of the storage groove 11 is slidably connected to a drawing tray 12, the left side of the drawing tray 12 is fixedly connected to a pull block 13, and the front of the drawing board 1 is fixedly connected to a pen slot 14.

[0021] refer to Figure 1 and Figure 5 Both sides of the front of the drawing board 1 are fixedly connected with a base plate 15, the front of the base plate 15 is fixedly connected with a spring 16, the front of the spring 16 is fixedly connected with an L-shaped pressing plate 17, and the front of the L-shaped pressing plate 17 is fixedly connected with a handle 18.

[0022] As a technical optimization solution of the present invention, through the setting of the spring 16, when it is necessary to fix the drawing paper on the front of the drawing board 1, the handle 18 on one side is pulled to make the L-shaped pressure plate 17 drive the spring 16 to stretch, and then one end of the drawing paper can be inserted into the back of the L-shaped pressure plate 17, and then the handle 18 is released to make the spring 16 contract and drive the L-shaped pressure plate 17 to move backward to clamp and fix the drawing paper, and then the handle 18 on the other side is pulled to repeat the above operation to fix the other end of the drawing paper, so that the drawing paper is fixed and flat, avoiding the curling and shaking of the drawing paper affecting the accuracy of the drawing.

[0023] refer to Figures 1 to 3 Magnetic strips 19 are fixedly connected to both sides of the back of the drawing board 1 and both sides of the top of the adjustment board 4.

[0024] As a technical optimization solution of the present invention, the magnetic strip 19 is provided to prevent the drawing board 1 and the adjustment board 4 from being easily separated, thereby avoiding the problem of damage to the internal structure caused by the opening and falling during transportation.

[0030] As a technical optimization solution of the present invention, the provision of the magnetic block 22 avoids the problem that the drawing tray 12 slides out during movement, causing the drawings inside to fall out, become dirty and become scrapped.

[0031] The working principle and use process of the utility model are as follows: when using, the user pulls the pull block 13 to take out the drawing paper inside the drawing tray 12, pulls the handle 18 on one side to make the L-shaped pressure plate 17 drive the spring 16 to stretch, and then inserts one end of the drawing paper into the back of the L-shaped pressure plate 17, and then releases the handle 18 to make the spring 16 contract and drive the L-shaped pressure plate 17 to move backward to clamp the drawing paper, and then pulls the handle 18 on the other side and repeats the above operation to fix the other end of the drawing paper, so that the drawing paper is fixed and flat and can be used for drawing. When it is necessary to adjust the drawing board 1, the drawing board 1 is rotated backward to the required angle, and the second limit strip 9 is flipped out and inserted into the corresponding interval between the two first limit strips 6 to complete the adjustment of the drawing angle of the drawing board 1, thereby avoiding the problem of discomfort to the cervical spine caused by the draftsman's long-term work with his head down. When the device needs to be folded up and carried, the drawing board 1 is flipped forward to retract the second limit strip 9, and the adjustment plate 4 is flipped forward to make it parallel to the drawing board 1, so that the drawing board 1 and the adjustment plate 4 can be folded together and stored, making it convenient for the draftsman to hold the handle 10 to carry the device.
