Abstract

The utility model provides a pen cap which is composed of a hollow sleeve with openings at two ends, a thumb position platform, an index finger position platform and a middle finger position platform, wherein the thumb position platform, the index finger position platform and the middle finger position platform are sequentially sleeved on the outer surface of the sleeve; an inner hole of the sleeve is tightly matched with an outer wall of a pen; one end edge of the thumb position platform, which is close to one end of a pen point, is provided with a thumb down screen which protrudes outwards; and when the pen cap is used, a contact area between fingers and the pen cap is increased when the pen is held, so that the pressure on the fingers by the pen is reduced when the pen is held to write and the degree of being hornyhanded can be effectively reduced; when the pen is held, the position from the fingers to the pen point is relatively fixed; and the thumb position platform, the index finger position platform and the middle finger position platform are arranged so that the position of holding the pen by the fingers is relatively fixed and the pen cap is good for reducing the inaccurate pen holding ways.

Description

A kind of pen cap

Technical field

The utility model relates to a kind of outer pen cap that uses of pen that is enclosed within, and belongs to the office appliance field.

Background technology

When writing, people use thumb, forefinger and middle finger to hold a pen usually, because the position that holds a pen is uncertain; Though teacher, the head of a family's indication is arranged, the posture that much human holds a pen is still incorrect, causes myopia, hunchback easily; And; Because hand is less with the contact area of pen, causes unit are pressure excessive, make finger play callus with the position that pen often contacts.

Therefore, need to seek a kind of aid that can make people adopt correct pen holding posture to write naturally, and can increase the area that finger contacts with pen.

Summary of the invention

The purpose of the utility model provides a kind of aid that can make people adopt correct pen holding posture to write naturally, and can increase the area that finger contacts with pen.

The technical scheme of the utility model is: a kind of pen cap, form by the hollow sleeve 1 of both ends open and the thumb bit platform 2, forefinger bit platform 3 and the middle finger bit platform 4 that are located at sleeve 1 outer surface successively; The outer wall tight fit of the endoporus of sleeve 1 and pen; Described thumb bit platform 2 is provided with outwards outstanding thumb retaining 21 down near an end edge of nib; During use, by thumb down retaining 21 towards the mode of nib penholder is gone into sleeve 1.

Described forefinger bit platform 3 is provided with outwards outstanding forefinger retaining 31 down near an end edge of nib.

Described middle finger bit platform 4 is provided with outwards outstanding middle finger retaining 41 down near an end edge of nib.

Retaining 21 is horizontal by an angle down for described thumb, and the scope of angle is at 30 to 60 degree.

Described forefinger retaining 31 down is parallel with horizontal plane.

Retaining 41 is horizontal by an angle down for described middle finger, and the scope of angle is at 30 to 60 degree.

Described thumb bit platform 2, forefinger bit platform 3 and middle finger bit platform 4 middle parts are provided with aduncate arc.

The endoporus of sleeve 1 is circle or hexagon.

Described thumb bit platform 2, forefinger bit platform 3 and middle finger bit platform 4 adopt elastic caoutchoucs to make.

Beneficial effect

1, through outside pen, putting the pen cap, the area that finger contacts with the pen cap when holding a pen is increased, pen can effectively alleviate callous degree to the pressure of finger when writing thereby reduced to hold a pen.

2, through outside pen, putting the pen cap; Make the position relative fixed of pointing when holding a pen apart from nib, and, the setting of thumb bit platform, forefinger bit platform and middle finger bit platform; Position when finger is held a pen is relative fixed also, helps to reduce the incorrect mode that holds a pen.
