The utility model discloses further set up to: the tank bottom fixedly connected with spring of standing groove.

Through adopting above-mentioned technical scheme, when utilizing the bolt to be connected connecting block and casing, elastic deformation takes place for the spring shrink, props bolt and connecting block tight, fastness when improving connecting block and casing and being connected.

The utility model discloses further set up to: the spring is subjected to thermomechanical treatment.

By adopting the technical scheme, the deformation strengthening and the heat treatment strengthening of the steel can be combined by the deformation heat treatment, so that the strength and the toughness of the steel are further improved, and the service life of the spring is prolonged.

To sum up, the utility model discloses following beneficial effect has:

through the cooperation work of connecting block and brush hair, when the eraser body moved to the inside of casing from the external world, the brush hair can carry out a clearance to the rubber bits on the eraser body, avoided specially cleaing away the rubber bits on the eraser body, labour saving and time saving.
