[0037] In this embodiment: the motor 401 is powered on and started, so that the output shaft of the running motor 401 drives the lead screw 404 to rotate in both directions. The lead screw 404 in the forward rotation state drives the movable frame 402 to move outward of the frame 2.

[0038] Please refer to this carefully. Figure 3 The movable drawing board assembly includes a movable frame 402 and a movable drawing board 403;

[0040] In this embodiment: the movable frame 402 moves outward from the frame 2 by the lead screw 404 in the forward rotation state. The movable frame 402 in the outward movement state then moves the movable drawing board 403 outward from the fixed drawing board 3. The movable drawing board 403 in the outward movement state increases the overall drawing area of ​​the device.

[0041] Please refer to this carefully. Figure 5 The lead screw 404 is connected to one side of the movable frame 402 via a lead screw seat, and the rotating lead screw 404 is used to drive the movable drawing board 403 to move through the movable frame 402.

[0042] In this embodiment: the output shaft of the running motor 401 drives the lead screw 404 to rotate in both directions. The lead screw 404 in the forward and reverse rotation state drives the movable frame 402 to move. The movable frame 402 in the moving state drives the movable drawing board 403 to move.

[0044] T-slot 501 is formed on the surface of frame 2, and T-block 502 is slidably connected to the inside of T-slot 501.

[0045] In this embodiment: the T-block 502 is moved along the trajectory of the T-slot 501, and the moving T-block 502 drives the magnetic plate 504 to move horizontally to a position suitable for limiting the engineering drawing.

[0046] Please refer to this carefully. Figure 3 The magnetic plate assembly includes a slide bar 503, a magnetic plate 504, and a spring 505;

[0047] The slide rod 503 is slidably connected to the T-block 502. The magnetic plate 504 is disposed at the end of the slide rod 503. The spring 505 is sleeved on the outside of the slide rod 503, and the two ends of the spring 505 are fixedly connected to the protrusion of the slide rod 503 and the T-block 502, respectively.

[0048] In this embodiment: the hand pinches the slide bar 503 and moves the slide bar 503 away from the fixed drawing board 3, which drives the magnetic plate 504 away from the fixed drawing board 3. At the same time, the slide bar 503 stretches the spring 505. Then, the end of the engineering drawing is placed in the gap between the magnetic plate 504 and the fixed drawing board 3. The hand releases the slide bar 503, so that the spring 505 in the reset state drives the slide bar 503 and the magnetic plate 504 to move closer to the fixed drawing board 3. Then the magnetic plate 504 and the fixed drawing board 3 are magnetically connected. The magnetically connected magnetic plate 504 and the fixed drawing board 3 limit the engineering drawing.

[0049] Please refer to this carefully. Figure 4 The magnetic plate 504 is magnetically connected to the fixed drawing board 3, and the magnetically connected magnetic plate 504 and the fixed drawing board 3 are used to limit the engineering drawings.

[0050] In this embodiment: when the spring 505 in the reset state drives the slide bar 503 and the magnetic plate 504 to move closer to the fixed drawing board 3, the magnetic plate 504 and the fixed drawing board 3 are magnetically connected, and the magnetic plate 504 and the fixed drawing board 3 in the magnetically connected state limit the engineering drawing.

[0051] Please refer to this carefully. Figure 3 The fixed drawing board 3 is used to house the movable drawing board 403 inside, and the movable drawing board 403 in the outward moving state is used to increase the overall drawing area of ​​the device.

[0052] In this embodiment: the screw 404 in the reverse rotation state drives the movable frame 402 to move inward into the frame 2, and the movable frame 402 in the inward movement state drives the movable drawing board 403 to move and be stored inside the fixed drawing board 3.

[0053] Working principle: When it is necessary to adjust the overall drawing area of ​​the device, firstly, the motor 401 is powered on and started, so that the output shaft of the running motor 401 drives the lead screw 404 to rotate in both directions. The lead screw 404 in the forward rotation state drives the movable frame 402 to move outward from the frame 2. The movable frame 402 in the outward movement state then drives the movable drawing plate 403 to move outward from the fixed drawing plate 3. The movable drawing plate 403 in the outward movement state increases the overall drawing area of ​​the device. As mentioned above, the lead screw 404 in the reverse rotation state drives the movable frame 402 to move inward from the frame 2. The movable frame 402 in the inward movement state then drives the movable drawing plate 403 to move and be stored inside the fixed drawing plate 3. Thus, the above structure facilitates the adjustment of the overall drawing area of ​​the device.

[0054] When engineering drawings need to be laid on the surface of the fixed drawing board 3, firstly, the T-block 502 is moved along the trajectory of the T-slot 501. The moving T-block 502 drives the magnetic plate 504 to move horizontally to a suitable position to limit the engineering drawings. Then, the sliding rod 503 is pinched and moved away from the fixed drawing board 3, which drives the magnetic plate 504 to move away from the fixed drawing board 3. At the same time, the sliding rod 503 stretches the spring 505. Then, the end of the engineering drawing is laid in the gap between the magnetic plate 504 and the fixed drawing board 3. The sliding rod 503 is released by hand, so that the spring 505 in the reset state drives the sliding rod 503 and the magnetic plate 504 to move closer to the fixed drawing board 3. Then, the magnetic plate 504 and the fixed drawing board 3 are magnetically connected. The magnetically connected magnetic plate 504 and the fixed drawing board 3 limit the engineering drawings. Since there are several limiting mechanisms 5, multiple engineering drawings can be limited.
