Abstract

The utility model relates to a multifunctional ball pen which comprises a penholder and is characterized in that a chalk holder is arranged at the end part of the penholder, and a piece of chalk is placed inside the chalk holder; an elastic component is arranged inside the chalk holder, one end of the elastic component is fixed with the end part of the penholder, the other end of the elastic component is connected with a chuck plate, and the chuck plate props against the tail part of the piece of chalk; a sliding chute is arranged on the inner side wall of the chalk holder, a bulge is formed on the side surface of the chuck plate, the bulge is matched with the sliding chute in size, a limiting stopper is arranged on one side of the sliding chute, which is far away from the elastic component, and the chuck plate is prevented from sliding out of the sliding chute. A guide groove is formed on the side wall of the chalk holder, limit slots are arranged inside the guide groove discontinuously, a pull rod is arranged on one side of the chuck plate, which faces to the guide groove, and the pull rod extends out of the guide groove. In the utility model, the chalk holder is arranged at the end part of a conventional ball pen, the piece of chalk can be loaded inside the chalk holder, the extended length of the chalk holder can be adjusted, and the multifunctional ball pen is convenient to use.

Description

Multi-functional ball pen

Technical field

The utility model relates to a kind of ball pen that can combine chalk to use, and belongs to stationery.

Background technology

For the teacher, ball pen and chalk are the stationery that often needs, but both functions all are single, and be convenient inadequately.

The utility model content

The utility model technical problem to be solved provides a kind of multi-functional ball pen, and is easy to use in conjunction with the function of ball pen and chalk, can carry.

For solving the problems of the technologies described above, the utility model is to realize like this

Multi-functional ball pen comprises penholder, in the end of penholder chalk sleeve is set, and places chalk in the chalk sleeve; Elastomeric element is set in the chalk sleeve, and an end and the pen arm end of elastomeric element are fixed, and the other end connects clamp, and clamp props up the chalk afterbody.

At the chalk sleeve madial wall chute is set, the clamp side is provided with prominent piece, prominent block size and chute coupling, and chute is provided with limited block away from a side of elastomeric element, prevents that clamp from skidding off chute.

Sidewall at chalk sleeve is convinced groove by patient analysis, is interrupted in this guide groove that stopper slot being set, and clamp is provided with pull bar towards a side of guide groove, stretches out this guide groove.

Described clamp is circular, and described elastomeric element is a spring.

The utility model has following positive effect: the utility model is provided with chalk sleeve in the end of conventional ball pen, can chalk be contained in the chalk sleeve, and can regulate the length of stretching out chalk sleeve, the convenient use.

The specific embodiment

Below in conjunction with the specific embodiment the utility model is done further detailed description.

Fig. 1 is the structural representation of the utility model, and with reference to shown in Figure 1, multi-functional ball pen comprises penholder 1, in the end of penholder chalk sleeve 2 is set, and places chalk 3 in the chalk sleeve 2.Elastomeric element 4 is set in the chalk sleeve 2, and an end of this elastomeric element 4 and the bottom of chalk sleeve are fixed, and the other end connects clamp 6, and clamp 6 contacts with chalk 3; At the chalk sleeve madial wall chute 5 is set, clamp 6 sides are provided with prominent piece 7, prominent piece 7 sizes and chute 5 couplings, and clamp 6 can slide along groove 5 by this prominent piece 7, and chute is provided with limited block away from a side of elastomeric element, prevents that clamp from skidding off chute.And the sidewall at chalk sleeve is convinced groove by patient analysis, is interrupted in this guide groove that stopper slot being set, and clamp is provided with pull bar 8 towards a side of guide groove, stretches out this guide groove.

At obsolete state at ordinary times, ball pen and chalk are convenient for carrying after all can putting on the cap for brush, when needing to use chalk; Only need be according to situation about using, move the prominent piece of control the moving of chute through pull bar along guide groove, be stuck in then in the different stopper slots; The length of chalk sleeve is stretched out in adjusting; Easy to use, can not fracture because of stretching out too much, and the finger of can not making dirty.

The above-mentioned specific embodiment does not limit the technical scheme of the utility model in any form, and every employing is equal to the protection domain that replacement or the technical scheme that mode obtained of equivalent transformation all drop on the utility model.
