Abstract

A pencil lengthening device relates to stationery for lengthening pencils, and is provided for overcoming weaknesses that a residual pencil stub is often abandoned, or is difficult to hold by hands. The pencil lengthening device mainly comprises a cylinder and a U-shaped clamp, wherein one end of the cylinder is open, and is convenient for inserting with a pencil stub, and the other end thereof is closed, and is fixedly connected with the U-shaped clamp through a fixing screw. The cylinder and the U-shaped clamp adopt light aluminum alloy materials, which lightens the weight of the pencil lengthening device, and prolongs the service life. The surface of the cylinder can be engraved or pasted with language or posters for inspiring study. The pencil lengthening device has the beneficial effects of low cost, attractive appearance, durability and convenient thrift and writing, increases the effective length of pencils, accords with the thought of energy conservation and emission reduction at present, and is study article simply improved.
