Abstract

The utility model relates to an anti-broken pen cap, which comprises a cylindrical pen tube. The passage inside the pen tube can be in a circular cylinder, hexagonal prism or octagonal prism structure. A rubber pad is stuck to the inter wall of the pen tube. A plurality of rear fins are processed on the surface of one end of the pen tube. When the anti-broken pen cap is used, the pen tube is enclosed on the penholder of a pencil; the rubber pad on the inner wall of the pen tube closely clings to the penholder to keep stable. During writing, a user can hold a pen to write without failure; when external force is exerted on the penholder, the penholder is prevented from rolling due to the rear fins, and the penholder is also prevented from being dropped down from the desk top. The utility model has the advantages of reasonable structure, being convenient and practical, novel shape and the like.

Description

The anti-breaking pen cap

Technical field the utility model relates to a kind of study article, especially a kind of anti-breaking pen cap.

Background technology is well-known, and pencil is a writing implement commonly used during people learn, paint and work.But present pencil all adopts cylinder, six prismatic or eight prism structures, and whole be direct rod shape entirely, is easy to roll under the external force effect being subjected to, and the result causes pencil to drop falling damage, make troubles to people's study and work.And can address the above problem without any instrument in the market, so we provide a kind of new-type pen cap very necessary at all.

The summary of the invention the purpose of this utility model provides a kind of anti-breaking pen cap, is used to solve the problem that general tool can't increase penholder stability.

For achieving the above object, the anti-breaking pen cap of the utility model comprises the cylinder shaft of a writing brush, and shaft of a writing brush internal pipeline can adopt cylinder, six prisms, eight prism structures, and wall is pasted one deck rubber mount within it; Be processed with a plurality of empennages at the shaft of a writing brush one end surfaces.

After adopting said structure, the user is enclosed within the shaft of a writing brush on the penholder of pencil, utilizes the rubber mount of shaft of a writing brush inwall tightly to be attached on the penholder, keeps stable; When writing, the user can normally hold a pen and write; Be subjected to external force at penholder and do the time spent,, also therefore reduced the danger that penholder drops from table top because the existence of empennage can avoid penholder to roll.

Compared with the prior art, the beneficial effects of the utility model are: rational in infrastructure, convenient and practical, modern design, and can avoid penholder to roll, prolong the service life of pencil.

Description of drawings Fig. 1 is the overall structure schematic diagram of the anti-breaking pen cap of the utility model.

Number in the figure: 1 is that the shaft of a writing brush, 2 is that rubber mount, 3 is empennage.

The specific embodiment as shown in Figure 1, the anti-breaking pen cap of the utility model comprises the cylinder shaft of a writing brush 1, the shaft of a writing brush 1 internal pipeline can adopt cylinder, six prisms, eight prism structures, wall is pasted one deck rubber mount 2 within it; Be processed with a plurality of empennages 3 at the shaft of a writing brush 1 one end surfaces.Wherein, the internal diameter of the shaft of a writing brush 1 can design processing according to the diameter of pencil.
