[0007] By adopting the above technical scheme, when construction engineers spread out the drawings for joint viewing, they first stretch out the auxiliary mechanism, and the stretched shape becomes a fan shape. The canvas is wound from one end of the winding mechanism to the other end of the winding mechanism, and the winding mechanism is manually pulled to clamp the winding mechanism on the display board and fastened with a locking member, so that the canvas is displayed in a fan shape. In addition, the prepared drawings are placed on the canvas, and the canvas and the drawings are adsorbed and clamped on both sides with magnetic blocks and iron blocks. Compared with the traditional laying, the viewers have a wider field of vision. When the work is finished, the locking member contacts the restriction on the winding mechanism, and the winding mechanism rolls up to the inside of the display board by itself, and the auxiliary mechanism is rotated to the original position fitting the display board.

[0008] Preferably, the winding mechanism includes a winding roller, a servo motor, a guide roller and a limit column, the winding roller is rotatably arranged inside the display board, the output shaft of the servo motor and the winding roller are fixed, the guide roller is rotatably arranged inside the display board, and the limit column is installed in a groove opened on the display board.

[0009] By adopting the above technical solution, after the servo motor is turned on, the output shaft of the servo motor drives the winding roller to rotate, and the winding roller drives the sail to be wound along the guide roller, so that the canvas is wound up by itself.

[0010] Preferably, the locking member comprises a pull rod and a card plate, the card plate slides on the display board, the pull rod is fixed to one end of the card plate, and the card plate and the limit column are snap-fitted.

[0011] By adopting the above technical solution, when the limiting column is stuck in the groove, the pull rod is pushed to plug and match the seals opened on the clamping plate and the limiting column to each other, thereby playing a limiting and fixing role.

[0012] Preferably, the auxiliary mechanism comprises a support column and a support frame, the support column is fixed on the display board, and the support frame and the support column are hingedly matched.

[0013] By adopting the above technical solution, the support frames are moved closer from both sides to the middle, and the sizes of the support frames are arranged from large to small. Moreover, the larger the support frames are, the smaller the angle between them and the display board is.

[0014] Preferably, the moving mechanism comprises a bracket and a self-locking universal wheel, the bracket is mounted on the bottom of the display board, and the self-locking universal wheel is mounted on the bracket.

[0015] The above technical solution makes it easier to move and carry the display board.

[0016] Preferably, a cavity is provided inside the display board for the winding roller to roll up the canvas.

[0017] By adopting the above technical solution, the cavity facilitates the canvas to be rolled up and rotated inside the display board.

[0018] Preferably, a limiting groove is provided on the propping frame.

[0019] By adopting the above technical solution, the limiting groove on the propping frame plays a limiting and guiding role for the canvas.
