Abstract

The utility model relates to a pencil, in particular to a novel environment-friendly pencil capable of saving wood resources. The novel environment-friendly pencil structurally comprises a plastic pencil holder and a metal inner tube, wherein the metal inner tube is hollow, a pencil lead is arranged in the metal inner tube, a copper flower is axially arranged at one section of the lower end of the metal inner tube so that the lower end of the metal inner tube is diverged in a petal shape, a spring is sheathed outside the diverged section, the lower end of the plastic pencil holder is connected with a conical pencil point by threads, a cap is connected at the upper end of the metal inner tube by threads, four metal blades are longitudinally arranged at the lower end of the cap, and the edges of the four metal blades are opposite in pairs so as to define a conical space in the middle. The novel environment-friendly pencil has a simple and reasonable structure and is convenient to use.

Description

The novel environment friendly pencil

Technical field

The utility model relates to a kind of pencil, is specially a kind of novel environment friendly pencil of saving timber resources.

Background technology

Pencil is a kind of writing implement commonly used in people's daily life, generally is made up of wood pen holder and plumbous matter pen core, along with the use of pencil, need constantly cutting wood pen holder, make penholder shorter and shorter,, often go out of use to using the later stage to make troubles to use owing to penholder is too short.And this Wood pencil needs to expend a large amount of timber in manufacture process, under the deficient day by day situation of China's Forest Resources, has formed a kind of excess waste to resource, has increased the weight of the burden of environmental protection simultaneously.For this reason, also occurred the pencil of some non-wood pen holders now, but on structural design, be still waiting further improvement, also remained on the function further to be strengthened.

Summary of the invention

The purpose of this utility model is to provide novel environment friendly pencil a kind of simple and reasonable for structure, easy to use.

The technical solution of the utility model is as follows: the novel environment friendly pencil comprises a plastic penholder and a metal inner pipe, metal inner pipe hollow, built-in lead for retractable pencil, one section axially has copper and blooms in the metal inner pipe lower end, making the metal inner pipe lower end be flap diverges to, the outside of diverging to one section is with spring, and the plastic penholder lower end is by the taper nib that is threaded.

Aforesaid novel environment friendly pencil wherein, is threaded one on metal inner pipe and blocks a shot, and the block lower end vertically is provided with four metal blades, and four metal blade edges are relative in twos, and the centre surrounds a cone space.

The utility model is simple in structure, during use, only need lead for retractable pencil is placed in the metal inner pipe, push the metal inner pipe upper end, stretch out from nib the metal inner pipe lower end, lead for retractable pencil promptly skids off from the metal inner pipe lower end automatically, unclamp metal inner pipe upper end, metal inner pipe bounces back under the effect of spring force, and the tapered hole by written lower end tightens the flap section of diverging to of metal inner pipe, lead for retractable pencil is fixed, very easy to use.In addition, the cone space that four metal blades of block lower end surround can be used as the usefulness of grinding lead for retractable pencil, has increased the function of use of pencil.

The specific embodiment

As shown in Figure 1 and Figure 2, the novel environment friendly pencil comprises a plastic penholder 2 and a metal inner pipe 4, plastic penholder 2 lower ends are by the taper nib 3 that is threaded, metal inner pipe 4 hollows, built-in lead for retractable pencil 6 axially has copper for one section in metal inner pipe 4 lower ends and blooms 5, makes metal inner pipe 4 lower ends be flap and diverges to, the outside of diverging to one section is with spring, and spring withstands on the boss that diverges to one section top.Be threaded one in metal inner pipe 4 upper ends and block a shot 1, the structure of block 1 as shown in Figure 3, it is relative in twos that 1 lower end of blocking a shot vertically is provided with 7, four metal blade 7 edges of four metal blades, the centre surrounds a cone space.

During use, only need lead for retractable pencil 6 is placed in the metal inner pipe 4, push metal inner pipe 4 upper ends, stretch out from nib 3 metal inner pipe 4 lower ends, and lead for retractable pencil 6 promptly skids off from metal inner pipe 4 lower ends automatically, unclamps metal inner pipe 4 upper ends, metal inner pipe 4 bounces back under the effect of spring force, tapered hole by written 3 lower ends is fixed lead for retractable pencil 6 the flap section of the diverging to chucking of metal inner pipe 4, and is very easy to use.

Four metal blades 7 that 1 lower end vertically is provided with of blocking a shot, the centre has surrounded a cone space, front end chap after writing for a long time when lead for retractable pencil, the lead for retractable pencil front end is placed in this cone space, the rotation block, lead for retractable pencil just can attenuate under the ablation of four metal blades 7, and this structure has increased the function of pencil, makes it more flexible multi-purpose.
