[0034] Working principle: When working, the driving structure 3 is started, so that the output end of the driving motor 31 rotates, so the worm 32 rotates. At this time, since the worm 32 and the worm wheel 31 are meshed with each other, the worm wheel 31 rotates, and then the two pulleys 21 at the front end rotate, so the belt 22 rotates, so the rear pulley 21 rotates, so that the threaded rod 41 rotates. At this time, the connecting column 42 is limited by the placement plate 51, so that the connecting column 42 is raised and lowered, so the height of the placement plate 51 rises. When the placement plate 51 reaches a suitable height, the clamping structures 7 on both sides are pulled to make the extension plate 61 slide to both sides, so the storage slot The telescopic rod 53 in the inner cavity of 52 is extended. When the extension plate 61 is taken out, the support spring 631 is extended and retracted, so the support plate 632 is raised and lowered, so that the upper end surface of the support plate 632 is level with the upper end surface of the placement plate 51. At this time, the personnel places the drawing on the upper end surface of the placement plate 51 and pulls the clamping plates 73 in the inner cavity of the clamping frames 71 on both sides at the same time, so that the clamping springs 72 contract, thereby placing the two sides of the drawing in the inner cavity of the clamping frames 71. At this time, the clamping plates 73 are released, so the clamping springs 72 are extended, so the height of the clamping plates 73 is lowered, and then the drawing is clamped and fixed by the extrusion between the clamping plates 73 and the pads 74.
