Abstract

The utility model relates to a pen easy to pull out the cap. The inner side of the sleeve (1) is provided with four protuberant triangular components (4), and the section corresponding to the location that a pen body is inserted in a pen sleeve opening is also provided with two protuberant triangular components (5). The pen sleeve (1) is embedded in a triangular groove (6) between the triangular components (4) through the components (5) and positioned on the pen body (2). The pen improves the traditional difficult method of time-taking and cap-pulling, provides a method of conveniently and easily pulling out the pen sleeve.

Description

A kind of pen that easily pulls out cap

Technical field

The utility model relates to a kind of stationery pen technical field, relates in particular to the technical field of the unlatching of the cap for brush.

Background technology

Pen is the Writing instrument that people use always, may need to use pen in the daily life at any time.Traditional pen generally is that a body end directly is plugged in the pen cap opening, cooperates by mutual size to be connected and fixed, and it is simple in structure, and is with low cost, but the pen cap is extracted the bigger strength of Chang Yaoyong.There is external screw thread and the internal thread that matches each other on an another kind of body and pen cap surface, and mainly are to rotate the pen cap by people, the pen cap is threaded with a body, but makes trouble, and will rotate than multi-turn and just can take down the pen cap, use very inconvenient.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of easy to use laborsaving, easily pulls up the pen of the pen cap.

The technical scheme that technical problem to be solved in the utility model adopted is, inboard face at the pen cap (1) has four delta-shaped members (4) projection, the corresponding part of pen in being inserted into pen cap opening also has two delta-shaped members (5) projection, parts (5) just in time and the triangular groove (6) between the parts (4) be complementary, the pen cap (1) is embedded into to peg graft in the triangular groove (6) between the parts (4) by parts 5 and is fixed on the body (2).

Compared with prior art, the utility model advantage is, because the pen cap and a body are pegged graft fixing by a delta-shaped members (4) and a delta-shaped members (5) that matches of the inboard face of the pen cap on one's body, as long as two parts are rotated round about simultaneously, both just can easily separate, do not need to make a lot of circles of very big power or rotation, thereby changed the time-consuming cover method of pulling out of traditional effort.Pen is simple and practical, does not influence the neatly generous of outward appearance, and manufacturing process is simple, is adapted at promoting the use of on the tool.

Description of drawings

Accompanying drawing 1 is a contour structures schematic diagram of the present utility model.

Accompanying drawing 2 is contour structures schematic diagrames that the utility model is pulled up a body of the pen cap.

Accompanying drawing 3 is cutaway views of the pen cap 1 of the present utility model.

The specific embodiment

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

This pen comprises the pen cap 1, the pen cap 3 and a body 2, the pen cap 1 with 2 as traditional pen cap, difference is that the inboard face of the pen cap 1 and 2 respectively has four delta-shaped members 4 projections, body 2 also respectively has two delta-shaped members 5 projections in the part that is inserted into pen cap opening, the triangular groove 6 that parts 5 form just in time and between the parts 4 is complementary, the pen cap is as long as one insert on one's body toward pen like this, parts 5 embed in the grooves 6, thereby the pen cap is fixed on one's body the pen, in the time of using, as long as to parts 4 and 5 one power, they are rotated round about, just can make two parts separately stressed decomposition, easily the pen cap is opened, be used for writing.

Claims (4)

1, a kind of pen that easily pulls out cap, it is characterized in that the bossed delta-shaped members of inboard face (4) at the pen cap (1), the corresponding part also bossed delta-shaped members (5) of a body (2) in being inserted into the pen cap (1) opening, the triangular groove (6) that forms between delta-shaped members (5) and the delta-shaped members (4) is complementary.

2, a kind of pen that easily pulls out cap according to claim 1, the inboard face that it is characterized in that the described pen cap (1) has the delta-shaped members (4) of four projections.
