Abstract

The utility model relates to a pencil holder for continuously using a pencil head and an eraser. Two cylinder pipe plugs are arranged in a section of rod-shaped circular pipe. An inner surface of the circular pipe and circumferential surfaces of the pipe plugs are respectively made into anastomosed rotary screw threads. Bottom surfaces towards both ends of the pencil holder for continuously using a pencil head and an eraser of two pipe plugs are respectively provided with a plurality of protruded nail heads which are respectively in contact with the pencil and the eraser. The pencil and the eraser are rotated for screwing out continuously the pipe plugs in the circular pipe for realizing the continuous use of the pencil and the eraser.

Description

A kind of short pencil, the continuous penholder of using of erasing rubber

The utility model relates to a kind of penholder that makes short pencil, the continuous usefulness of erasing rubber.

At present, short pencil and erasing rubber the situation of holding incessantly can occur pointing before using, and at this moment, can only abandon or fill in continuous usefulness in the pipe of a constant depth, caused waste or to the shortcoming of the pencil bad adaptability of different length.

The purpose of this utility model provides a kind of penholder, and it can not only make pencil stub insert continuous usefulness, and can make long pencil precession put into it, in use screws out then, until finishing using constantly.Play not frangibility of protection pen core simultaneously.

The utility model is achieved in that in one section shaft-like pipe, two cylinder pipe closes are set, pipe inner surface and pipe close periphery are made the rotation screw thread that matches respectively, and two pipe closes make one (not containing central point) or some outstanding ailheads respectively towards the bottom surface at penholder two ends.One end of pipe is placed pencil stub, and the other end is placed erasing rubber, and contact with ailhead, plays fixation, and wipes to rotate by pencil and skin and rotate pipe close, thereby regulates the length that pencil, skin wiping expose.

Adopt such scheme, can make pencil stub, the continuous usefulness of erasing rubber, also can make than long pencil and place its interior use, in use constantly screw out, thereby protect not frangibility of pen core, economy consciousness and the manipulative ability that can cultivate the student, simple in structure.

Below in conjunction with drawings and Examples the utility model is further specified.

The longitudinal section of Fig. 1, the utility model embodiment;

Fig. 2, be the A-A profile of Fig. 1;

Among the figure: 1-shaft of a writing brush 2-pipe close 3-screw thread 4-ailhead

In an embodiment, the footpath is consistent with pencil simply in the pipe of the shaft of a writing brush (1), table is made rotation screw thread (3) in the tube, pipe close (2) is a cylinder, its circumferential surface make with the shaft of a writing brush in corresponding to rotation screw thread (3), pipe close bottom surface diameter (not containing threaded portion) should be consistent with the penholder internal diameter, place two identical pipe closes in the every shaft of a writing brush, make four outstanding ailheads (4) at each pipe close towards the bottom surface of tip of the brushstyle of a writing or painting symmetry, contact with erasing rubber with pencil respectively, Propelling pencil with sharpener in cap or skin are wiped, and pipe close is precession or back-out thereupon.

Claims

1, a kind of short pencil, the continuous penholder of using of erasing rubber, it is by one section shaft-like shaft of a writing brush and place the cylinder pipe close in it to form, it is characterized in that: the periphery of the inner surface of the described shaft of a writing brush (1) and described pipe close (2) is made the rotation screw thread that coincide mutually respectively, pipe close (2) rotates in the shaft of a writing brush (1), pipe close (2) at it towards pipe end and wipe the bottom surface that contact with pencil or skin and do not contain central spot and have ailhead (4) that at least one is given prominence to.

2, continue with penholder, it is characterized in that according to the described short pencil of claim 1, erasing rubber: place two same pipe closes (2) in the described shaft of a writing brush (1).

3, according to claim 1 or 2 described short pencils, erasing rubber is continuous use penholder, it is characterized in that: described pipe close (2) is wiped the symmetrical making and settlement in bottom surface four the outstanding ailheads (4) that contacts at it towards pipe end and with pencil or skin.
