Abstract

The utility model relates to a pen sleeve suitable for refills of different lengths and different thicknesses, which belongs to stationary and office supplies and mainly solves the problem that the ordinary pen sleeve can not hold refills of any length and thickness. The pen sleeve comprises a lower sleeve, a threaded sleeve and an upper sleeve. The two ends of the threaded sleeve are open, the upper end of the threaded sleeve is provided with internal threads and connected with the upper sleeve provided with external threads, and the lower end of the threaded sleeve is provided with external threads and connected with the lower sleeve provided with internal threads; and the upper sleeve comprises a knob, external threads with lengths of 2 cm and a refill insertion slot. The position of the upper sleeve can be adjusted by adjusting the knob, so as to ensure the normal use of refills of different lengths; and the inner wall of the refill insertion slot is in a conical shape, so as to ensure the normal use of refills of different thicknesses. The pen sleeve provided by the utility model has a simple structure, and is economical and practical.

Description

A kind of pen cap of suitable different length different thicknesses pen core

Technical field

The utility model relates to a kind of stationery, specifically can use the pen cap of different length different thicknesses pen core.

Background technology

The pen cap in the market is that length is fixed mostly, can only use a kind of fixing pen core, can not be applicable to ball pen and gel ink pen pen core simultaneously, the gel ink pen pen core of different length different thicknesses can not use the same pen cap, the replacing pen core must be selected corresponding length and thickness for use, cumbersome, make troubles to the user.

Summary of the invention

Purpose of design of the present utility model is the weak point that solves in the background technology, designs a kind of pen cap of suitable different length different thicknesses pen core.

Technical scheme: this pen cap comprises lower sleeve, screw shell and upper bush.The screw shell both ends open, there is internal thread the upper end, with have externally threaded upper bush and be connected, there is external screw thread the lower end, be connected with the lower sleeve that has internal thread, upper bush comprises knob, long external screw thread and the pen core slot of 2cm, can regulate the position of upper bush by adjusting knob, fixedly the pen core of different length has guaranteed the normal use of different length pen core; It is conical that pen core slot inwall is, and can block the pen core of different thicknesses.

Fig. 1 is each exploded view of the utility model.

Fig. 2 is the utility model structural representation.

Among the figure: 1, lower sleeve, 2, screw shell, 3, upper bush, 4, the pen core slot, 5, knob.

The specific embodiment

As follows with reference to accompanying drawing: a kind of pen cap of applicable different length different thicknesses pen core comprises lower sleeve 1, screw shell 2, upper bush 3, pen core slot 4 and knob 5.Screw shell 2 both ends opens, there is internal thread the upper end, with have externally threaded upper bush 3 and be connected, there is external screw thread the lower end, be connected with the lower sleeve 1 that has internal thread, upper bush 3 comprises pen core slot 4 and knob 5, can regulate the position of upper bush 3 by adjusting knob 5, has guaranteed the normal use of different length pen core; It is conical that pen core slot 4 inwalls are, and can guarantee that the different thicknesses pen core normally uses.

During use, earlier with upper bush 3 precession screw shells 2, again with screw shell 2 precession lower sleeves 1.Only need turn on screw shell 2 when changing pen core, upper bush 3 and screw shell 2 are taken down together, put into the position of passing through to rotate knob 5 adjusting upper bushes 3 behind the pen core, guarantee the normal use of different length pen core.

Claims
