Description

Can install the pen of multiple pen core

The utility model is a kind of pen that installs multiple pen core, belongs to the writing implement technical fields of using more.

The existing so far quite permanent history of tool development, and gather the tool that multiple pen core is an one.As have the Multi-colour pen of multiple color pen core, also early have commercially available, yet general many pen cores tool is many with seeing of rotation penholder exchange pen core or push type exchange pen core, their some complexity that structurally all seems at large.Like this, as long as one of them finding is impaired, lump-sum will be scrapped, and not only waste resource, and on this type of tool price generally all than higher, increased consumer's burden.And its volume is bigger.Slightly dislike inconvenience during gripping, pen core is also too short, often produces bigger bending during external force pressure, when the pen core that stretches out penholder is write, can be subjected to the extruding of other pen cores and produces crookedly, causes to write to have some setbacks.In addition, known many pen cores tool is when changing pen core, and the heart must be dismantled the penholder direction in advance and can carry out, and not only operation is difficult for, and also causes damage easily.

In order to overcome above-mentioned defective, the purpose of this utility model provides a kind of pen that installs multiple pen core, and this pen has simple in structure, characteristics easy to use with low cost.

Solution of the present utility model is: a kind of pen that installs multiple pen core is provided, it places the pen core in the penholder to form by one-pen bar and Duo Zhi, its tail end inner chamber chamber wall of described penholder is provided with the axial slide that equates with the pen core number, this chute is the stage casing broad, the shape that two ends are narrower, its wider part position, stage casing is slightly larger than the pen core diameter, and on chute, on the two side walls of lower end, respectively be provided with an engaging concave station, described pen core respectively has a control knob, this control knob is made of its post footpath and pen core internal diameter size plunger that mates and the arcuation shell fragment that is socketed in plunger back-end and by above-mentioned plunger control knob is inserted in the pen core tail end, also be provided with air drain on the above-mentioned plunger, and the collar both sides of shell fragment respectively are provided with a boss that engages concave station inner chamber size coupling with above-mentioned penholder chute, above-mentioned pen core is inserted in (or taking-up) penholder by chute, the shell fragment two ends of control knob then are close on the outer wall of penholder on the pen core, and be fastened on by its boss in the engaging concave station of chute upper end or lower end, when this shell fragment is sunk under external force, thereby its boss can break away from the engaging concave station pen core is driven via control knob and stretch out or the penholder of withdrawing in, and after the shell fragment reinstatement, the boss of control knob can be fastened on the interior location of engaging concave station of chute once more.According to such scheme of the present utility model, this pen that can install multiple pen core is only set up the control knob device in the pen core rear end, so simple in structure, not fragile, with low cost except that having general penholder that tool has and pen core.And it also can merge multiple tool function, and the user takes one and comprise polychrome, can be daily required to deal with, can be rated as practical and convenient generation new product.

Below in conjunction with the explanation in addition detailed of specific embodiment shown in the accompanying drawing to the pen that installs multiple pen core of the present utility model.
