[0012] As a further solution of the utility model: the bottom sleeve rod and the mounting seat are movably arranged, and the upper hanging rod and the telescopic rod are movably arranged.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By pushing the positioning pawl outward as a whole to disconnect the limit of the positioning pawl on the ratchet gear, the lifting spring compressed between the outer storage rod and the inner storage rod will be reset as a whole, and the overall length of the telescopic rod will be changed. Under the action of the upper hanging rod and the lower hanging rod, the entire map will be vertically flattened, so it is convenient for teaching and display.

[0015] After the upper hanging rod is rotated and opened from the outside of the telescopic rod, the clamp is clamped at the upper end of the map. The tension spring in the guide groove pulls the clamp toward the outer end, thereby flattening the map horizontally. BRIEF DESCRIPTION OF THE DRAWINGS
