After the movable plate 8 is pulled out, the positioning plate 11 is set horizontally, and then the reset type indexing pin 19 is inserted into the second positioning hole 18 to complete the fixation.

[0041] Working principle: the clamping assembly 7 on the winding rod 6 and the clamping assembly 7 on the movable plate 8 aligned with it jointly clamp a drawing (that is, the double-threaded rod 14 is rotated axially so that the double-threaded rod 14 makes the two clamping plates 12 approach each other, so that the two clamping plates 12 clamp the drawing). In the absence of external force, the reset assembly enables the winding rod 6 to have the ability to rotate, that is, the winding rod 6 winds the drawing on itself. When in use, select one of the winding rods 6, pull out the movable plate 8, and after the movable plate 8 is pulled out, the positioning plate 11 is set horizontally, and then the reset type indexing pin 19 is inserted into the second positioning hole 18 to complete the fixation. The movable plate 8 causes the winding rod 6 to rotate axially through the drawing, and then the drawing is unfolded and no longer used. The movable plate 8 is released, and the winding rod 6 winds the drawing on itself again, and then the other movable plates 8 are pulled out.
