Abstract

The utility model relates to an eraser, particularly an electric eraser. The utility model is provided with a housing body, and a motor and a battery are arranged in the housing body The battery is connected with the motor by a switch, and a common eraser is fixed on a rotary shaft on the motor. The utility model is adopted. Since the rotary speed of the motor is high, when a person erases words, eraser chips and paper chips are dispersed in a granular mode. The utility model avoids the defects that the eraser chips and the paper chips in the past are mixed to form strip shapes, which results in new pollution, a person uses the eraser by a hand to erase writings, which easily result in the damage of paper surfaces since the person controls improperly force.

Description

Motor-driven eraser

The utility model relates to a kind of rubber, is in particular a kind of motor-driven eraser.

At present, student study, staff draw etc. and to run into when rewriteeing, and mostly still adopt erasing rubber, because be artificial wiping, firmly are difficult to accomplish identical, careless slightly at every turn, will damage paper; In addition, wipe paper scrap down, the rubber bits form strip, and between the contacting of rubber and paper, drag, very easily make by the surperficial recontamination of wiping.

The purpose of this utility model will overcome above-mentioned defective exactly, designs a kind of new rubber.

Technical solution of the present utility model:

Motor, battery are arranged in the housing, and battery is connected with motor by switch, driven by motor one turning cylinder, and rubber is fixedly connected on the turning cylinder.

Accompanying drawing:

Fig. 1--the utility model structural representation.

Embodiment:

As shown in Figure 1, motor 3, battery 2 are arranged in the housing 1, battery 2 is connected with motor 3 by switch 4, and turning cylinder 5 is arranged on the motor 3, and rubber 6 is fixedly connected on the turning cylinder 5.During use, pull switch 4, battery 2 provides power supply for motor 3, so the turning cylinder 5 on the motor 3 rotates, drives the rubber 6 of fixedlying connected with turning cylinder 5 and rotates.When rubber 6 touches the place that need wipe word on the paper, because motor 3 rotating speeds are higher, the rubber bits on the rubber 6 are graininess with paper scrap and scatter, and such one can not fray paper, and two can recontamination, and works very well.

Claims (1)

1. motor-driven eraser is characterized in that battery 2, motor 3 are arranged in the housing 1, and battery 2 is connected with motor 3 by switch 4, and turning cylinder 5 is arranged on the battery 3, and rubber 6 is fixedlyed connected with turning cylinder 5.
