Abstract

The utility model provides a multi-purpose replaceable pen refill, belongs to stationery, and mainly solves the problem about unchanged written stroke weight by a traditional pen refill. The multi-purpose replaceable pen refill structurally comprises pen points, a pen tube and a plug, wherein each pen point and the pen tube adopt a separable insertion connection structure; the pen point consists of a steel ball, a sleeve and a connection socket; the pen point body is connected with the upper end of the connection socket in an insertion way; the lower end of the connection socket is connected with the top end of the pen tube in an insertion way; the pen tube is filled with ink; the detachable plug is arranged at the tail part of the pen tube; one end of the plug is recess-shaped. When the multi-purpose replaceable pen refill is in use, the required pen point is inserted into the pen tube, and the rest pen points are sequentially connected to the plug in an insertion way; when thick strokes are required to be written, all that is needed is to substitute a pen point in a larger-size for the pen point on the pen tube, and vice versa ; according to the utility model, the function of one pen with multiple purposes can be achieved, good convenience in storage, portability and high universality are realized, and the manufacturing cost is reduced.

Description

A kind of multiplex replaceable pen core

Technical field
