Technical Field

The invention relates to the technical field of office supplies, in particular to a multifunctional pen for offices.

Background

The pen, which is a kind of learning and office supplies, is used almost throughout various fields of work, study and life, and among them, the most used are both a ball pen and a fountain pen. The two kinds of pens mainly comprise a pen holder, a pen cap and a pen core. After the ink is used, the refill needs to be replaced to continue to be used, and the length of the refill is often not matched with that of the pen holder due to different lengths of various pens, so that the refill needs to be cut to be installed in the pen holder to continue to be used.

When the pen core is cut, the old pen core is required to be used as a length reference, and the new pen core is cut to a corresponding length by a knife and then can be arranged in the pen holder for use. In the cutting process, the old pen core and the new pen core are arranged in parallel, the heads of the old pen core and the new pen core are aligned, and the redundant parts at the tail parts of the old pen core and the new pen core are cut off. This process takes trouble hard, and because the head is difficult for aligning when tailorring, the refill also rolls easily, causes to cut inaccurately, and in addition, the user more than half can not carry the cutter more, just more inconvenient when changing the refill.

Disclosure of Invention

In order to solve the technical problem, the invention provides a multifunctional pen for offices.

The invention provides a multifunctional pen for offices, compared with the related technology, the technical scheme of the invention is as follows:
