[0022] As a technical optimization solution of the present invention, through the setting of the rotating drum 21, when the user's line of sight distance deviates from the height of the adjustment plate 2, the rotating drum 21 can be rotated to make the screw rod 23 move up and down to drive the adjustment plate 2 to adjust until it is adjusted to the required height, so as to adapt to users of different heights, thereby further improving the applicability of the device.

When the drawing to be clamped is large, the first pull handles 13 on both sides are pulled outward at the same time, so that the slide bar 4 and the sleeve 7 slide outward inside the adjustment groove 3 to expand the clamping distance. When the drawing is small, the first pull handles 13 on both sides are pushed inward, and the connecting rod 9 slides inward along the slide groove 20. At the same time, the slide bar 4 and the sleeve 7 slide inward, and the round block 5 on the left side of the slide bar 4 will slide into the sleeve 7 through the ring 6 to shorten the clamping distance. After adjusting the distance according to the size of the drawing, it can be pulled in sequence. The first handle 13 and the second handle 18 on one side stretch the first spring 11 and the second spring 16 to separate the first side plate 14 and the first clamping plate 10, put one end of the drawing into the front of the first clamping plate 10 and release the first handle 13, so that the first spring 11 contracts and drives the first side plate 14 and the anti-slip strip 28 to clamp one end of the drawing, and at the same time, the second spring 16 stretches to separate the second side plate 19 from the second clamping plate 15, put the other end of the drawing into the front of the second clamping plate 15 and release the second handle 18, so that the second spring 16 contracts and drives the second side plate 19 and the anti-slip strip 28 at its bottom to clamp the other end of the drawing, and repeat the above steps to clamp the compared drawings.
