Abstract

A telescopic writing pen adopts the structure that a pen refill is placed in an inner hole of a pen cap, the front end of the pen cap is in threaded connection with a sealing cap, a pen point of the pen refill extends out of the sealing cap, and the pen cap, the sealing cap and the pen refill form a short pen; an outer cylinder is provided with a sliding chute with pass-through interior and exterior, the sliding chute is formed by folded edges at two ends of the outer cylinder in the axial length direction; the pen cap is placed in an inner hole of the outer cylinder and is in clearance fit with the outer cylinder; a pushing button is formed by fixedly integrating a straight lever and a rear cap, wherein the front end of the straight lever is threaded; the straight lever of the pushing button penetrates the sliding chute, and the threaded part at the front end of the straight lever is screwed with a threaded hole on the pen cap; a hooking neb is arranged at the rear end of the outer cylinder; and a hook is connected with the hooking neb through a hanging ring. The writing pen is in the short state in normal times so as to be carried conveniently; when in use, the writing pen can be extended to a length approximate to that of an ordinary pen to facilitate holding, so that the contradiction of short in carrying and long in writing is solved, and people can develop a habit of carrying a pen, thereby bring convenience for life.

Description

Flexible lettering pen

Technical field:

The utility model relates to a kind of lettering pen, the lettering pen that especially a kind of length can be stretched.

Background technology:

People often run into the difficult situation that but can not find pen when wanting to write note or recording phone number out of doors, reason is to be inconvenient to carry because common pen is long, if and that pen is done is very short, is not easy again to grasp and is difficult to write, so people are not just with the custom of pen.

Summary of the invention:

The purpose of this utility model provides a kind of flexible lettering pen, solves that common pen is long to be inconvenient to carry and contradiction that short pen is difficult to write.

The purpose of this utility model realizes as follows: pen core is placed in the pen cap endoporus, and pen cap front end is by the sealing cap that is threaded, and the nib of pen core stretches out outside sealing cap, and the pen cap, sealing cap and pen core constitute short pen; A urceolus is arranged, and urceolus has chute penetrating inside and outside, and chute is the flanging formation along the axial length direction of urceolus and two ends; The pen cap is placed on urceolus endoporus intermediate gap and cooperates, and fixedly all-in-one-piece push button of a threaded straight-bar of front end and back cap is arranged, and the threaded portion that the straight-bar of push button passes chute and its front end is screwed on the screwed hole on the pen cap, and the push button and the pen cap are fixed together.This pen in use, promote push button forward with finger, the pen cap is skidded off from urceolus, when moving to the chute front end, push button rotates an angle, make push button enter the flanging place of chute with the relative urceolus axial restraint of the pen cap, when writing, can avoid short pen in urceolus, to withdraw like this, the penholder length that constitutes by short pen and urceolus that needing to keep; After using, stir push button reverse turn disengagement chute flanging, promote push button then backward, push button moves and drives gradually short pen backward along chute and is withdrawn in the urceolus, push button rotates to the flanging place after arriving the chute rearmost end, makes the push button axial limiting, avoids short pen to skid off in urceolus, this lettering pen is in the state of shortest length, is easy to carry.

There is hanging nose the rear end of urceolus, by a link hook is connected on the hanging nose.This lettering pen can be suspended on the key ring by hook, be convenient for carrying.Take off from key ring during use.

The utility model is in the short state of length at ordinary times, be easy to carry, and can be extended into the length of being convenient to grasp in use, solved the contradiction between needing when carrying to lack, need grow when writing near conventional pen, be convenient to people and form custom, for life has brought facility with pen.

Description of drawings:

Accompanying drawing is the structural representation of the flexible lettering pen of the utility model.

The specific embodiment:

With reference to accompanying drawing, pen core 8 is placed in the pen cap 6 endoporus, and the pen cap 6 front ends are by the sealing cap 7 that is threaded, and the nib of pen core 8 stretches out outside sealing cap 7, and the pen cap 6, sealing cap 7 and pen core 8 constitute short pen, and pen core 8 can be ball pen.A urceolus 3 is arranged, and urceolus 3 has chute penetrating inside and outside 4, and chute 4 is the flanging formation along the axial length direction of urceolus 3 and two ends; The pen cap 6 is placed on urceolus 3 endoporus intermediate gaps and cooperates, and fixedly all-in-one-piece push button 5 of a threaded straight-bar of front end and back cap is arranged, and the threaded portion that the straight-bar of push button 5 passes chute 4 and its front end is screwed on the screwed hole on the pen cap 6.There is hanging nose 2 rear end of urceolus 3, by a link hook 1 is connected on the hanging nose 2, this lettering pen can be suspended on the key ring by linking up with 1.
