Abstract

The utility model discloses a screw type pen point replacement tool which solves the problems that the pen point is different to pull out during replacement, and the ink is splashed during pulling out the pen. The screw type pen point replacement tool comprises a screw replacement device, a pen point positioning device and a refill positioning device, wherein a screw pillar of the screw replacement device and a screw hole of the pen point positioning device are connected by female and male threads; the pen point positioning device is provided with a screw hole, a pen point positioning groove and a refill positioning groove; the refill positioning device is provided with a positioning pin and a refill pipe hole; and the refill pipe hole corresponds to the refill positioning groove and is used for placing a refill pipe. The screw type pen point replacement tool adopts the smart and unique screw type design, so that the pen point is convenient to disassemble quickly, and two refills can be assembled and disassembled simultaneously, and the replacement process is easy and convenient to operate quickly. The ink in the refill is prevented from splashing out so as to greatly save the resources and reduce the ink loss. The screw type pen point replacement tool is applicable to all gel ink refills and has high practicability and adaptability.

Description

Spiral written replacing instrument

Technical field:

The utility model relates to a kind of written replacing instrument, relates to a kind of spiral written replacing instrument of gel ink pen or rather.

Background technology:

Gel ink pen (core) is a kind of ball pen (aqueous ballpoint pen) of viscosity between water-based and oiliness of writing medium, also is called mound pen, ball pen or water-color paintbrush.It has concurrently PenWith the characteristics of oiliness ball pen, and write lubricated smooth, lines are even.Along with the invention of gel ink pen and popularize, writing implements such as ball pen, the pen people's sight of fading out gradually, it has become the writing implement of popular in the world a kind of novelty.

Yet people are also perplexed by some defectives of gel ink pen, for example: be inverted ink leak for a long time; Printing ink is easily withered; Following water is inhomogeneous etc.In addition also have a defective the most fatal: the gel ink pen nib causes gel ink pen to occur writing intermittently, the phenomenon that has some setbacks through external force effect meeting generation plastic deformation such as firmly pushing, drop.If continuing use can influence writing effect and write mood.If abandon then can cause certain pollution and waste.

The way of generally acknowledging is now: still intact nib is extracted after using up pen and ink with other one, is installed on the gel ink pen of nib damage, continues to use.But, occur easily in the replacing process that nib is difficult to pull up, printing ink problem such as splash when extracting.

Summary of the invention:

The purpose of this utility model is to overcome the deficiencies in the prior art a kind of simple in structure, easy to operate, simple and direct, written instrument of safety replacing is provided, solved being difficult to of occurring in the written replacing process pull up, printing ink problem such as splash when extracting, can dismantle, install two pen cores simultaneously.

The utility model comprises, it is characterized in that comprising spiral more changing device, written positioner, pen core positioner; Spiral more changing device comprises shell, base and borded pile, and base and borded pile fuse, be provided with in the enclosure, and rotating base, borded pile rotates thereupon; The nib positioner is provided with threaded hole, written locating slot and pen core locating slot, and threaded hole relies on negative and positive to be threaded with borded pile; The pen core positioner is provided with alignment pin and pen core pore, and the pen core pore is corresponding with the pen core locating slot, is used to place pen core tube.

Using method: (1) rotating screw is changing device more, written positioner is screwed out, with the projection of two pen cores snap in written locating slot, pen core tube snaps in the pen core locating slot.(2) with written positioner precession spiral changing device more.(3) plug the pen core positioner, make two pen cores insert the pen core pore, screw alignment pin.(4) rotating screw changing device more breaks away from nib and pen core tube.(5) rotate 180 ° of positioners of pen core (aliging with graduation mark), the reverse rotation spiral is changing device more, and nib is installed.(6) rotate the butterfly alignment pin, take off the pen core positioner.(7) rotating screw changing device more screws out written positioner once more, takes off the pen core of more finishing changing.

As shown from the above technical solution, the utlity model has following beneficial effect: it is more efficient and convenient that 1, the spiral design of ingenious uniqueness makes the dismounting of nib, can dismantle, install two pen cores simultaneously, and it is simple, convenient, rapid to change process operation.2, avoid the pen core ink to spatter outward, greatly saved resource, reduced the loss of ink, met national energy-saving and emission-reduction policy.3, manufacturing process is simple, is easy to processing, and is with low cost.4, be applicable to all Neutral ball-point for ball-point pen, have stronger practicality and adaptability.
