Description

A kind of finger pen of replaceable pen core

Technical field

The utility model relates to a kind of stationery, the writing pen that particularly a kind of special personnel or place are used.

Background technology

When writing or drawing, be generally to hold a pen with several fingers of whole hand, write or write while doing other work with hand, pen need to be put down, but at some Code in Hazardous Special Locations, while drawing as job site, pen can be put nowhere, also have some special populations, as finger disabled person, cannot hold a pen.Therefore have human hair to understand finger-tip pen, be by the pen cap on a finger, write.In patent documentation, just there are the many pieces of patent documentations such as CN200720186504.2, CN201120371467.9 and CN200720017402.8 to disclose similar technology.As Chinese patent literature 200720017402.8 discloses a kind of finger pen, it is by referring to that overhead guard, vial and securing member three parts form; Finger pen is " fingerstall " shape, and its nib has carried out shortization to be processed, and refers to that overhead guard inner side designs and produces according to finger end profiles feature completely, refers to can establish on overhead guard the aperture of ventilative use; Vial is vertically provided with elongated " V " type opening, so that fastening allowance to be provided; Refer to that overhead guard bottom is provided with small boss, nib is installed on small boss; Vial be divided into crooked with non-crooked two kinds, be about to finger pen and be set to bend pipe finger pen and straight tube finger pen two classes; Securing member finger pen is fastened on finger.The utility model structure is small and exquisite, and writing posture, without strict demand, is stood, sits, kneels, lies, crouched and all can write, and has removed to greatest extent the constraint of writing people's limbs, writes for a long time and is also difficult for producing fatigue.The condition of writing is loose, and to thing to sit on, sitting posture, without strict demand, individuals with disabilities also can realize smooth writing equally with abled person.

But there is following defect in above-mentioned design: this pen is disposable use, after the ink that inside holds is finished, together with overhead guard, vial and securing member, all must discard, and again buys; Pen core head exposes, during temporarily without written indicia function, for the impaired need of anti-pen core head are frequently extractd; Due to people's finger have big or small thickness minute, the model of the new new vial of buying may not be certain elongated short the adapting of thick fingers with me.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of finger pen, and it can use for a long time, after ink runs out of, needn't discard whole fingerstall, only need to change pen core, pen core head is realized and freely to be retracted, and prevents that pen core head is impaired during construction operation, prevents the pen core ink article around of defiling simultaneously.

For solving the problems of the technologies described above, technical solution adopted in the utility model is:

A kind of finger pen of replaceable pen core, comprise fingerstall, be positioned at the restraint zone on fingerstall top, described fingerstall arranged outside has the shaft of a writing brush for accommodating pen refill that is set to one with fingerstall, the bending curvature of the anterior front end along fingerstall of the shaft of a writing brush also forms the shaft of a writing brush point being connected with fingerstall one in the dead ahead of fingerstall, in shaft of a writing brush point, be provided with the hole of coming in and going out for the pen core head of pen core, the lower end of shaft of a writing brush inside is provided with the spring being sleeved on pen core head, and spring top is between pen core and the lower surface of shaft of a writing brush endoporus; Described pen core head stretches out angle rear and that fingerstall front axle line forms between 40 ° to 50 °, and described shaft of a writing brush top is separated with fingerstall, and shaft of a writing brush upper end is connected with the cap for brush by buckle; In the cap for brush, be provided with the rotation head part that contacts with pen core top and press head part, rotation head part and press head part and contact cooperation by rotating teeth, rotates head part, presses between head part and cap for brush inwall and coordinate by different slideways.

The utility model further improves and is: the shape of cross section of the described shaft of a writing brush and pen core is ellipse or pancake, and it is cylindrical rotating head part, pressing head part, and described installation of slide track is on ellipse or the long limit of pancake.

The buckle that connects the cap for brush and the shaft of a writing brush is included in the snap fit that is positioned at lower end and the superposed pressure point that in the cap for brush, hollow out goes out, on the shaft of a writing brush, be provided with the hole clipping corresponding with snap fit, on the shaft of a writing brush of hole clipping top, be provided with protruding fulcrum, fulcrum is corresponding between snap fit and pressure point.

The length of described fingerstall is greater than the length of two joint fingers, and restraint zone is positioned at the 3rd joint position of finger; The inside portion of described fingerstall is divided and is arranged to fexible film, and front end and the Outboard Sections of fingerstall are arranged to rigid support.

Owing to adopting technique scheme, the beneficial effect that the utility model produces is:

Finger pen of the present utility model can be used for a long time, after ink runs out of, needn't discard whole fingerstall, only needs to change pen core.Pen core head of the present utility model can freely be retracted, and can prevent that pen core head is impaired when not writing, and prevents the pen core ink article around of defiling simultaneously.Pen core head stretches out angle rear and that fingerstall front axle line forms and is not more than 45 °, can, the in the situation that of finger natural torsion, complete the line work of writing.The cap for brush is connected with the shaft of a writing brush by buckle, conveniently takes off the cap for brush and changes pen core.The shaft of a writing brush, pen core are arranged to ellipse or pancake, can increase the capacity of ink in pen core, are also convenient to pen core crooked in the shaft of a writing brush, mobile.

Shaft of a writing brush top the be convenient to cap for brush separated with fingerstall loads and unloads, in use, also can make by the bending of dactylus the cap for brush outstanding, press the cap for brush press head part time, can make to press head part withstands on arbitrary objects and can make pen core move up and down, nib stretched out or be retracted in the shaft of a writing brush, not needing to use another finger presses.Facilitate like this people of another hand inconvenience to use.

The inside portion of fingerstall is divided and is arranged to the tactile thing sensation that fexible film can increase finger tripe, and front end and the Outboard Sections of fingerstall are arranged to rigid support, can provide strong support for the shaft of a writing brush.
