Abstract

The utility model relates to a rubber using a motor as the power. The utility model connect the motor, a switch and a battery in series to form a closed circuit which is arranged in a casing, and the rubber is fixed on the shaft of the motor by using a contact head. The rubber is driven by a motor to rotation at the high speed to erase the writing trace of pens and pencils.

Description

Electric rubber

The utility model is a kind of novel stationery that can wipe pen or pencil writing.

As everyone knows, present various Drawing Design personnel and the employed erasing rubber of student are manual, very inconvenient, and its major defect one is easily paper to be frayed, the 2nd, the scope of wiping big often with desire to wipe partly around partly also wipe a slice, the 3rd, erasing speed is slow.

The purpose of this utility model is that it can not fray paper for above all kinds of personnel provide a kind of novel erasing rubber, and the scope of wiping can accurately control, and erasing speed is fast.

For achieving the above object, structure of the present utility model is: battery becomes the closed-loop path by switch and is assembled in the shell with motor in series, be fixed on erasing rubber on the axle of motor with chuck, need only during use erasing rubber is touched paper, press switch, and move along person's handwriting, the motor drives erasing rubber rotates at a high speed just can make things convenient for promptly wipes written trace.

The utility model can overcome the above-mentioned shortcoming of manual erasing rubber owing to be manual with electronic replacement, and is rapidly convenient when wiping, and guarantees can not fray paper (when exerting oneself when excessive the automatic stall of motor meeting), and can accurately control the scope of wiping.

Figure one is a vertical section of the present utility model structural map, among the figure 1, shell, and 2, battery, 3, reed, 4, micromotor, 5, chuck, 6, erasing rubber, 7, microswitch.

Figure two is a circuit connection diagram of the present utility model

In figure one, battery (2) is two joint polyphones, motor (4) adopts 31 type toy motors, the two terminals welding back of reed (3) and motor (4) by switch (7) and battery+,-utmost point Elastic Contact, chuck is installed on the motor reel, erasing rubber just is clamped in the chuck, by the motor drives rotation, and can change at any time.

Claims (1)

1. A kind of erasing rubber, motor, battery and switch series are unified into the closed-loop path, it is characterized in that fixing on motor reel a chuck, are used for the clamping erasing rubber.
