Rotating shaft, rotating shaft terminal connection rotating disc, rotating disc are arranged in closure, and torsion spring, dust-proof sleeve side are provided with rotating disc
Face offers inlet and outlet, imports and exports interior slide and is provided with checking computations cloth, checking computations cloth one ends wound on the rotary shaft, checks the cloth other end and connected
Pumping rod is connect, checking computations cloth upper surface is pasted with waterproofing membrane, and inlet and outlet inner side is provided with erasing sliver.
As the further scheme of the present invention：The dust-proof sleeve is hollow structure.
As the further scheme of the present invention：The one end is fixed on rotating disc, and the torsion spring other end is fixed on close
Cover on inwall.
As the further scheme of the present invention：The inlet and outlet are string configuration.
As the further scheme of the present invention：The length of the pumping rod is more than the length of inlet and outlet.
As the further scheme of the present invention：The checking computations cloth is made of nonwoven cloth.
Compared with prior art, the beneficial effects of the invention are as follows：A kind of mathematical studying desk, it is simple in construction, make
With conveniently, occupying little space, may be reused, avoid the waste of paper, environmental protection and saving, good dustproof effect is convenient to pull out, and
It can automatically reclaim, realize the auto-erasing of person's handwriting, using effect is good.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Refer to Fig. 1~3, in the embodiment of the present invention, a kind of mathematical studying desk, including it is desktop 2, checking computations cloth 3, dust-proof
Sleeve 4, pumping rod 7 and erasing sliver 10, the desktop 2 are fixed in table frame 1, and the top edge of desktop 2 is provided with dust-proof sleeve 4,
Dust-proof sleeve 4 is hollow structure, and the dust-proof both ends of sleeve 4 are provided with closure 9, and the dust-proof inside of sleeve 4 is provided with rotary shaft 6, rotated
The both ends of axle 6 connect rotating disc 8, and rotating disc 8 is arranged in closure 9, torsion spring 11 is provided with rotating disc 8, the one end of torsion spring 11 is consolidated
It is scheduled on rotating disc 8, the other end of torsion spring 11 is fixed on the inwall of closure 9, and the dust-proof side of sleeve 4 offers inlet and outlet 5, disengaging
Mouth 5 is string configuration, is slided in inlet and outlet 5 provided with cloth 3 is checked, for the checking computations one ends wound of cloth 3 in rotary shaft 6, checking computations cloth 3 is another
One end connects pumping rod 7, and the length of pumping rod 7 is more than the length of inlet and outlet 5, and checking computations cloth 3 is made of nonwoven cloth, checks cloth
