Description

A kind of health care pen

[affiliated technical field]

The utility model relates to a kind of health care pen, especially can correct the health care pen of pen holding posture.

[background technology]

Existing common ball pen, form by penholder, the nib of penholder one end and the pen core in the penholder, penholder is a pipe, the children that this kind pen writes for firm study are difficult to grasp correct pen griping position, form incorrect writing posture easily, and incorrect writing posture can cause myopia.

[summary of the invention]

The utility model provides a kind of health care pen of correcting pen griping position, thereby grasps correct writing posture, reaches the bathomorphic purpose of prevention.

To achieve these goals, the utility model adopts following technical scheme: comprise penholder, the nib of penholder one end and the pen core in the penholder, its characteristics are that the pen core bottom is provided with one and its coaxial reference column, have wedge-shaped slot on the reference column vertically, the shallow end of wedge-shaped slot is positioned at the end near nib, on the penholder and uniform three apertures of reference column opposite position, is furnished with T shape piece on the hole, the taper vertical part of T shape piece is passed aperture and is inserted in the wedge-shaped slot on the reference column, one spring housing is with leather sheath and has encased T shape piece below reference column on the pen core on the penholder.

For avoiding the taper vertical part dislocation of wedge-shaped slot and T shape piece, prevent reference column around axial rotation, also have vertically a strip fin on the penholder inwall, the groove that matches is with it arranged on the reference column.

For guaranteeing that at the most correct pen griping position reference column is positioned at one-inch place, nib top.

The beneficial effects of the utility model are the pressure leather sheaths that only press...with one's finger when writing, leather sheath extruding T shape piece, the taper vertical part of T shape piece promotes reference column compression spring, the drive pen core moves down, pen core stretches out nib and just can write, the back pen core under the reset response of spring of loosing one's grip is withdrawn in the penholder, if hand is not according to being pressed in correct pen griping position, pen core just can not stretch out, also just can not write normally, therefore can force to correct pen griping position when writing, the tram that helps children to hold a pen, prevention myopia.

[description of drawings]

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Among the figure, 1. pen core, 2. penholder, 21. apertures, 22. fins, 3. spring, 4. nib, 5. reference column, 51. wedge-shaped slots, 52. grooves, 6. leather sheath, 7.T shape piece.

[specific embodiment]

Embodiment 1: pen core 1 is placed on by nib 4 among Fig. 1, in the shaft of a writing brush that penholder 2 is formed by connecting, the pen core bottom is provided with one and its coaxial reference column 5, have wedge-shaped slot 51 on the reference column vertically, the shallow end of wedge-shaped slot is positioned at the end near nib, there is a spring 3 the reference column below on the pen core, on the penholder and uniform three apertures 21 of reference column opposite position, is furnished with T shape piece 7 on the hole, the taper vertical part of T shape piece is passed aperture and is inserted in the wedge-shaped slot on the reference column, be with leather sheath 6 on the penholder and encased T shape piece, finger only is placed on the correct place of holding a pen and pushes leather sheath 6 simultaneously, leather sheath 6 extruding T shape pieces 7, be squeezed its taper vertical part of T shape piece 7 promotes reference column 5 and moves down, make the relatively move deep end of wedge-shaped slot 51 of the taper vertical part of T shape piece 7, being fixed on reference column 5 on the pen core 1 this moment just drives pen core 1 and moves downward and compress spring 3, nib just can stretch out nib 4 and normally write, the spring 3 of reference column 5 belows restores to the original state behind the bar and reference column 5 push up back original position openhanded writeing for the first time, and drive pen core 1 is withdrawn in the penholder 2.For avoiding the rotation of reference column 5, penholder 2 inwall upper edges are axially arranged with fin 22, and reference column 5 is provided with associated groove 52.Because with pen contacts three fingers are arranged when writing, be convenient to three fingers and firmly hold a pen so on pen, opened 3 uniform apertures 21.T shape piece 7 is positioned at the nib one-inch place that makes progress, thereby forces the beginner to grasp correct pen griping position, the more effective myopia that causes owing to pen holding posture is incorrect of preventing.

Embodiment 2 and example 1 difference are that T shape piece 7 pastes on the inwall that is fixed on leather sheath 6.
