Abstract

The utility model discloses an extensible pencil, which comprises two half casings [1], pencil cores [2] and a half casing fixing device, wherein the half casings [1] have the same shape, and are hinged together and relatively attached to form the pencil casing; pencil core grooves [4] adaptive to the pencil cores [2] in the diameter are formed in the center of the half casings [1]; and the pencil cores [2] are mounted in two casings [1] and fixed by the half casing fixing device. The utility model is free from sharpening the casing, so that the environment cannot be polluted; and the pencil core can be sharpened at any size according to the requirement.

Description

Extensible pencil

Technical field

The utility model relates to pencil, especially the shell of pencil.

Background technology

Pencil is a kind of widely used writing implement.Pencil commonly used comprises shell and parcel pen core in the enclosure.People make pen core exposed in use with the cutter arborescence shell of pruning gradually, are used for writing.Owing to write in the use, therefore the shell of need repeatedly pruning the expensive time, has brought a lot of inconvenience to people.Shell of pruning simultaneously and pen core pollute the environment and the people's that make dirty finger.For addressing the above problem, people have worked out propelling pencil, as long as directly press the penholder upper end with hand, pen core will stretch out automatically, and the use of propelling pencil has improved service efficiency greatly, does not also pollute the environment.But propelling pencil is because of the construction problem of self, and the pen core diameter of use is less, so the scope of application is little.

The utility model content

It is low that the purpose of this utility model solves arborescence shell pencil service efficiency exactly, easy contaminated environment, and the problem that the propelling pencil scope of application is little provides a kind of extensible pencil.

The technical solution adopted in the utility model is: extensible pencil, it is characterized in that it is to comprise half-shells, pen core and the half-shells fixture that can constitute the pencil shell after the identical hinged and relative applying of two shapes, described half-shells central authorities are provided with the pen core groove suitable with the pen core diameter, and the half-shells fixture is carried out behind the cored fixing to two half-shells.

Adopt technique scheme, pen core is placed in the pen core groove of half-shells, two half-shells are relatively also fixed with the half-shells fixture, promptly can be used to use.After the pen core that stretches out uses, open the half-shells fixture, two half-shells are separated, promote the pen core reach, two pen cores are relatively also fixed with the half-shells fixture, can use again.

Above-mentioned half-shells fixture is the pen cap, and the described pen cap is sleeved on outside the half-shells, and two half-shells are fixed.The pen cap is sleeved on outside two half-shells, can reach two half-shells and fix.

Above-mentioned half-shells fixture be trip and with the suitable draw-in groove of trip, trip and draw-in groove are individually fixed in two half-shells opposite faces.Cooperate by trip and draw-in groove, can realize that two half-shells are fixed as a whole shell.

In sum, the utility model beneficial effect is: because pen core of the present utility model can be adjusted into arbitrarily big size dimension as required, so the scope of application is wide; Therefore the shell because the utility model need not pruned does not pollute the environment yet.

The specific embodiment

Embodiment 1, as shown in Figure 1, it is to comprise half-shells 1, pen core 2 and the half-shells fixture that can constitute the pencil shell after the identical hinged and relative applying of two shapes, two half-shells 1 are undertaken hinged in the bottom by hinge 3, half-shells 1 central authorities are provided with and the suitable pen core groove 4 of pen core 2 diameters, the half-shells fixture is the pen cap 5, the pen cap 5 as shown in Figure 2, it is a resilient sleeve, front end is provided with the tapering similar to the half-shells front end, it is sleeved on half-shells 1 front end when using, and two half-shells are fixed.

Embodiment 2, and as shown in Figure 3, it is hinged that two half-shells 1 are undertaken by hinge 3 in the side, the half-shells fixture be trip 6 and with the suitable draw-in groove 7 of trip 6, trip 6 and draw-in groove 7 are individually fixed in two half-shells opposite faces.

But the technical solution of the utility model sample can be used on the various pens of other close with the pencil principle, as eyebrow pencil etc., all is to belong in the utility model protection domain therefore.
