Problems solved by technology

[0003] At present, the pencil still includes a cylindrical carbonaceous pencil lead and a wood layer wrapped around the carbonaceous pencil lead. When in use, the wood layer needs to be cut off with a knife or a pencil sharpener, which not only increases the user's cutting time wood layer, but also increases the wood used to make pencils, and because the use of pencils with wood layers makes it impossible to use to a very short time, it also causes a certain amount of waste

Abstract

The invention relates to a self-peeling pencil without using wood and a working method. The self-peeling pencil without using the wood comprises a handheld pipe and a middle connecting pipe connectedto the front end portion of the handheld pipe. A head end connecting pipe is connected to the front end portion of the middle connecting pipe. An inner pipe used for containing pencil leads, a limiting ejection sleeve, an elastic clamping head and a cutter sleeve provided with an inner cutter are sequentially arranged in the handheld pipe, the middle connecting pipe and a head end connecting pipebody. A flange abutting against the front end face of the handheld pipe is arranged at the position, close to the front end head, of the periphery wall of the inner pipe. The pencil can be directly used, use of wood is saved, and use convenience is improved.

Description

Technical field: [0001] The invention provides a multifunctional pencil, in particular a self-sharpening pencil without wood and a working method. Background technique: [0002] The pencil wood layer was completed by a carpenter named William Monroe in the United States in 1812. The machine invented by Monroe can cut standardized thin wood strips with a length of 5-18 cm, and can dig a piece of wood just right in the middle of the thin wood strips. Fit the groove of the pencil lead, put the pencil lead into the groove, and then tighten and glue the two wooden strips, which made the first pencil shaft in the modern sense. Standard procedure for penholders. [0003] At present, the pencil still includes a cylindrical carbonaceous pencil lead and a wood layer wrapped around the carbonaceous pencil lead. When in use, the wood layer needs to be cut off with a knife or a pencil sharpener, which not only increases the user's cutting time The time of wood layer, but also increased...
