when writing teaching is needed, the sliding rod 10 slides upwards from the inside of the barrel seat 9, the cross beam 11 at the upper end of the sliding rod 10 is jacked up, the writing cloth 14 inside the cloth rolling barrel 13 is pulled out at the moment, and the writing teaching can be carried out, and after the sliding rod 10 descends, the spring 17 drives the cloth rolling shaft 15 to reset and rotate, so that the writing cloth 14 is wound and collected into the cloth rolling barrel 13.

Second embodiment: in the first embodiment, the cross bar 12 fixed to the outer end of the writing cloth 14 is fixedly bonded to the cross beam 11, and when the slide bar 10 and the cross beam 11 at the upper end of the slide bar 10 are lifted, the cross bar 12 and the writing cloth 14 are pulled out from the inside of the cloth winding drum 13, which is convenient for teaching. In the process, the two slide bars 10 and the beam 11 form a rectangular frame, the writing cloth 14 occupies the whole space of the rectangular frame, and when the slide bars 10 are lifted to a preset proper position, the slide bars 10 are locked to the cylinder seat 9 through the limiting screws 18 to complete the fixation of the rectangular frame; after the writing operation is finished, the limit screw 18 is loosened, the clockwork spring 17 drives the cloth winding shaft 15 to reset and rotate, the writing cloth 14 is wound and collected into the cloth winding drum 13, and in the resetting and rotating process, the cross beam 12 and the slide rod 10 are fixedly arranged with the cross beam 11, the cross beam 11 and the slide rod 10 also descend along with the cross beam 12, and the slide rod 10 is accommodated in the drum seat 9. However, the inventor of the present invention found in teaching practice that in some specific teaching occasions, a plurality of teaching model samples need to be suspended to facilitate teaching display, or model sample display and character writing need to be combined to facilitate combining a real object with a picture and a text, and in the first embodiment, since the writing cloth 14 occupies the whole space of the rectangular frame formed by the sliding rod 10 and the cross beam 11, the rectangular frame only has a writing function, and the suspending function of the teaching model samples cannot be considered, so the design of the first embodiment obviously cannot meet some specific teaching occasions.

In order to overcome the above-mentioned drawbacks, the inventor of the present invention designs the cross bar 12 and the cross beam 11 fixed to the outer end of the writing cloth 14 as a separable structure. Specifically, the inner sides of the two sliding rods 10 are respectively provided with a sliding rail, two ends of the cross rod 12 are in rolling contact with the sliding rails through pulleys, the strip-shaped electromagnets are embedded in the two sliding rods 10 and are electrically connected to a power supply and an electrified switch, the pulleys at the two ends of the cross bar 12 are made of iron materials, the limit screw 18 has the control function of an electrified switch, when the slide bar 10 ascends to the preset proper position, the slide bar 10 is locked to the cylinder seat 9 through the limiting screw 18 to complete the fixing of the rectangular frame body, and simultaneously when the slide bar 10 completes the locking, the limit screw 18 opens the power-on switch, the long-strip-shaped electromagnets embedded in the two slide bars 10 are powered on and have magnetic attraction, the power-on switch is closed after the limit screw 18 is loosened, the long-strip-shaped electromagnets embedded in the two slide bars 10 do not have magnetic attraction, and the plurality of hooks are detachably mounted on the cross beam 11.

The specific working process of the design is as follows: when the sliding rod 10 and the cross beam 11 at the upper end of the sliding rod 10 ascend, the writing cloth 14 is still wound and collected in the cloth winding drum 13, when the sliding rod 10 ascends to a preset proper position, the sliding rod 10 is locked on the drum seat 9 through the limit screw 18 to complete the fixation of the rectangular frame formed by the sliding rod 10 and the cross beam 11, in the process, the limit screw 18 opens the power switch, the long-strip-shaped electromagnets embedded in the two sliding rods 10 are powered on and have magnetic attraction, the cross rod 12 is manually lifted, the pulleys at the two ends of the cross rod 12 generate rolling displacement in the sliding rail at the inner side of the sliding rod 10, when the cross rod 12 is lifted to the proper position, the pulleys at the two ends of the cross rod 12 are fixed with the two sliding rods 10 through the magnetic attraction, and the important point is that the magnetic attraction is greater than the elastic force to realize the stable connection between the cross rod 12 and the sliding rod 10. At this time, the writing cloth 14 occupies a part of the space of the rectangular frame body to be used for completing the graphic writing teaching, and the other part of the space of the frame body is used for hanging the teaching model sample, thereby realizing the combination of the model sample display and the writing teaching. After the teaching work is finished, the limit screw 18 is loosened, the power-on switch is turned off, the strip-shaped electromagnets embedded in the two slide bars 10 do not have magnetic attraction any more, the cloth winding shaft 15 is driven by the clockwork spring 17 to reset and rotate, the writing cloth 14 is wound and collected into the cloth winding drum 13, then certain pressure can be manually applied to the cross beam 11, the slide bars 10 are contained in the drum base 9, and therefore the collection operation of the whole teaching tool is finished. Compared with the first embodiment, the design of the second embodiment enables the rectangular frame formed by the sliding rod 10 and the cross beam 11 to have the model sample display function and the writing teaching function, and can be suitable for various different specific teaching occasions.

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.
