Description

Novel push type writing pen

Technical Field

The utility model belongs to the technical field of pen articles for use, especially, relate to a novel push type writing pen.

Background

Pen holders are arranged on pen products such as ball pens, propelling pencils and the like, and can hold pens on clothes pockets, notebooks and other articles, so that the pen holder is convenient to carry. However, the existing pen clips on the market are relatively fixed structures, the thickness of an object clamped by the pen clips is limited, and if the pen clips are clamped on a thick object, the pen clips can lose effectiveness after repeated use, so that the service life of the pen is shortened.

In order to prevent the pen clip from being damaged due to inelastic deformation caused by excessive pulling during use, chinese patent CN 207241237 discloses a "pen clip", in which a limiting member for preventing the pen clip main body from inelastic deformation is fixedly disposed on the pen clip main body. The above structure is complicated and the appearance is not beautiful enough, and it does not fundamentally solve the problem of use of clamping on a thick object.

There is also pen clip shell fragment structure to the design of rotation type writing pen, the pen-holder divide into pen-holder and lower pen-holder two parts this moment, the slewing mechanism who is connected with the refill sets up in pen-holder down, the pen clip dustcoat sets up in last pen-holder, the part of pen clip passes the pen-holder and arranges in the pen clip dustcoat, pen clip shell fragment one end offsets with last pen-holder inner wall, the other end offsets with the pen clip, make the pen clip shell fragment can provide the elasticity that resumes the initial position for the pen clip, but above-mentioned pen clip shell fragment structure is unsuitable in push type writing pen, the pen-holder of push type writing pen is integral type structure, if set up the pen clip shell fragment with the same mode, it will drive the activity of pen clip shell fragment to move about the cap is moved, can's unable function of realizing the.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a simple structure, the pen clip can be applicable to the cramping thing of different thickness, the effective long service life of pen clip, the simple novel push type writing pen of assembly.

The utility model provides a technical scheme that its technical problem adopted is: a novel push type writing pen at least comprises a refill, a pen clip, a pen holder with a pen clip mounting hole, a pen clip outer cover limited in the pen holder, a jumping mechanism which is arranged in the pen holder and is controlled to jump by the press cap, a connecting elastic sheet with the upper end connected with the press cap and the lower end connected with the jumping mechanism, and a pen clip elastic sheet arranged in the pen clip outer cover; the pen clip elastic sheet is abutted against the inner side wall of the pen clip outer cover, the pen clip elastic sheet is sleeved on the pen clip elastic sheet after the pen clip penetrates through the pen clip mounting hole and is arranged in the pen clip outer cover, the pen clip elastic sheet is abutted against the pen clip elastic sheet, and when one end of the pen clip moves towards the direction far away from the side wall of the pen holder, the pen clip elastic sheet generates deformation for resetting the pen clip.
