Environment-friendly non-sharpening break-proof pencil cover

Abstract

The invention relates to an environment-friendly non-sharpening break-proof pencil cover, which comprises a pencil lead hole, a locking outer conical head, a slotted inner cone body, a slotted inner cone body fixing part, a slotted inner cone body elastic material part, a locking thread, a tooth slot, mobile positioning teeth, edges, a main pencil body, a push button, a pencil lead push rod, a pencil lead sharpening cap matching surface, a blade, a pencil lead sharpening cap and an inner cone body open slot. Through the locking of the locking outer conical head and the locking thread as well as the planing of the blade in the pencil lead sharpening cap, the environment-friendly non-sharpening break-proof pencil cover ensures the effects of environmental friendliness, convenience, long service life, free sharpening and breaking prevention and also has the advantages of comfort and esthetic appearance of a traditional pencil.

Description

technical field [0001] The invention relates to a pencil jacket, in particular to an environment-friendly, cut-free and break-proof pencil jacket that can be quickly locked, saves wood of the pencil jacket, and prevents the lead core from breaking easily. Background technique [0002] At present, most of the materials of various pencils commonly used are wood, and there will be a large section of pencil head left in use that cannot be used any more. This consumes a large amount of wood raw materials in terms of ecological environmental protection, and has also caused a huge impact in terms of material saving. Although there are many types of mechanical pencils on the market, they cannot achieve the same feeling and effect as wooden pencils in terms of writing feeling and application effect, so most engineering drafters and students are still accustomed to using traditional wooden pencils, traditional wooden pencils The use of pens not only brings problems in terms of ecologi...

[0002] At present, most of the materials of various pencils commonly used are wood, and there will be a large section of pencil head left in use that cannot be used any more. This consumes a large amount of wood raw materials in terms of ecological environmental protection, and has also caused a huge impact in terms of material saving. Although there are many types of mechanical pencils on the market, they cannot achieve the same feeling and effect as wooden pencils in terms of writing feeling and application effect, so most engineering drafters and students are still accustomed to using traditional wooden pencils, traditional wooden pencils The use of pens not only brings problems in terms of ecological environment protection and material conservation, but also has problems such as poor planing, easy lead breakage during planing and use, and too many remaining pen heads that are not suitable for continuous use.
