Description

Length-adjustable combined type ball pen

Technical field

The utility model relates to a kind of writing implement, a kind of specifically length-adjustable combined type ball pen.

Background technology

At present, the teacher gos over examination papers, the student does one's assignment all will use ball pen, yet the ball pen of prior art and pen core thereof exist multiple model and specification, pen core and pen container need strictness to be used, otherwise can't assemble, thereby often see the user, even will occur the situation that has pen core and pen container also not necessarily can normally use like this because change less than the model pen core consistent or pen container and worry with specification, influence student or teacher's use, comparatively inconvenience.

Summary of the invention

Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of combined type ball pen simple in structure, length-adjustable is provided.

The technical solution of the utility model realizes in the following manner, this length-adjustable combined type ball pen, its structure comprises the cap for brush, penholder, vertebra cap, pen core, described cap for brush bottom has positioning screw hole, evenly have and the corresponding spacing screw of positioning screw hole on penholder top, screw passes positioning screw hole and is fixed in the spacing screw.

The spacing screw of being opened on the described penholder is no less than 5.

The beneficial effect that the utility model is compared with prior art produced is:

Length-adjustable combined type ball pen of the present utility model has characteristics such as simple in structure, easy to use, the contraposition setting of positioning screw hole and spacing screw makes the adjustable length of this ball pen, so no matter to be the length that teacher or student can adjust ball pen in use according to the actual needs of oneself, and to get final product with using after the screw secure; The pen container of combined type ball pen of the present utility model and cap for brush combination are adjustable, can assemble the refill for ball-point pen of any model, realize one-object-many-purposes, are easy to promote the use of.
