When adjusting the length of soft magnetic stripe 11, accessible pulling ring 14 drives spacing slide bar 13 and slides in the slide opening, thereby through fixed lantern ring 20, L shape gag lever post 21 drives magnetic fixture block 22 and shifts up, thereby relieve the pressing of soft magnetic stripe 11, and rotate corresponding fan-shaped stopper 19 and make fan-shaped stopper 19 change to fixed lantern ring 20, support fixed lantern ring 20 between the magnetic part connecting cylinder 7, thereby can prevent that spacing slide bar 13 from reseing under compression spring 16's spring action, later alright begin to adjust the length of soft magnetic stripe 11, can rotate out fan-shaped stopper 19 after the regulation is accomplished and remove to support and make magnetic fixture block 22 reseed under spring action, thereby compress tightly soft magnetic stripe 11 and drawing with the help of self suction, further reduce the gap of drawing corner.
In daily teaching work, this show board can provide main hollow show board 5, the show region in 6 three ascending directions of two vice hollow show boards, the cooperation removes the removal effect of base 30 and can realize classification and the fast switch-over to the show drawing, supplementary baffle 26 and magnetic force plywood 29 at this moment mutually support and can carry on spacingly to two vice hollow show boards 6, make this show board remain stable, also can rotate two vice hollow show boards 6 and make it change to the both sides of main hollow show board 5 respectively, and utilize magnetic force inserted block 27, concatenation slot 28 is spacing, thereby utilize two vice hollow show boards 6 to expand the show region of main hollow show board 5, thereby improve the area of exhibition on the single direction, make the function of this show board nimble, it is convenient to use.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
