Abstract

The utility model relates to the improvement of a pencil holding device, in particular to a pencil holding position limitation clip which is used for limiting the slide of a hand toward a nib when a pupil holds a pencil. The penc 1 il holding position limitation clip of the utility model is formed by that a pencil holding position limitation clip composed of a clip 2, a spring 3, a pencil sleeve 4 and a pin shaft 5 is arranged at the position below the hukou of a hand when a pencil is held. The utility model has the advantages that the distance between the hand and the pencil is limited to the position respecting the line of sight when writing letters; eyes are not needed to be close to a book to look letter writing; therefore, the entire sitting posture is kept natural and correct; the defects of myopia, strabismus and humpback caused by the incorrect letter writing posture can be overcome fundamentally. Due to the pencil sleeve arranged on the pencil holding position limitation clip, the pencil can be used when the length is not less than 5 cm; the use value of the pencil is increased. The utility model is particularly adapted to the pupils when learning letter writing, and has a better use effect when matched with a tearing and taking off type pencil.

Description

The pencil spacing card that holds a pen

Technical field

The utility model relates to the hold a pen improvement of device of a kind of pencil, the pencil that the restriction hand slided to nib when particularly a kind of pupil the held a pen spacing card that holds a pen.

Background technology

Writing posture when writing is extremely important, when particularly the pupil just learns to write, mostly point near nib, because finger has blocked sight line, force the student askew to the left side, croucs, even the student's eyes that have get close to books, in the course of time myopia, stravismus, bow-backedly forming unconsciously.

Patent of invention 99116219.6 discloses " method of writing position indicator is set " on pencil, its scheme is to indicate the tram of writing, can remind the method for correct writing posture again, but user's writing time is long, hand can slide to nib unconsciously, still can't play the effect that correctly holds a pen; Utility model patent 93215027.6 discloses " health lettering pen ", its scheme is in the place ahead of pen arm end one support to be set, and can avoid the slip of hand to nib effectively, and finger can not obstruct the view, but nib and penholder are write firmly inconsistent not at straight line.

Summary of the invention

The purpose of this utility model provides a kind of hand of can effectively avoiding and slides and the pencil that makes sitting posture keep nature the to rectify spacing card that holds a pen to nib.

The utility model pencil spacing card that holds a pen is made up of pencil, spacing clip, spring, the pen cap, and its scheme is: the tiger upper/lower positions place of hand is provided with by spring and controls pencil that the spacing clip folding and the pen cap etc. the constitute spacing card that holds a pen when pencil holds a pen.

Compared with the prior art, the utility model has the advantages that, hand is limited to the position of not obstructing the view with the distance of pen when writing, eyes needn't get close to books and see and write, thereby make whole sitting posture keep nature to rectify, can fundamentally overcome the defective that forms myopia, stravismus hunchback because of writing posture is incorrect.Spacing card is provided with the pen cap because the utility model pencil holds a pen, and pencil can improve the use value of pencil with being not less than 5cm to residue.The utility model is specially adapted to the pupil and uses when learning to write, and to be used effect better with the ripping type pencil.

The specific embodiment

Below in conjunction with drawings and Examples the utility model content is described further:

The utility model pencil spacing card that holds a pen is made up of pencil 1, spacing clip 2, spring 3, the pen cap 4, it is characterized in that: the spacing card that holds a pen that the tiger lower position setting of hand is made of spacing clip 2, spring 3 pens cap 4 and bearing pin 5 when pencil holds a pen.

Described spacing clip 2 is for curving inwardly the clamping pencil around the front end of central spring 3 bearing pin foldings, and tail end is equipped with the clip of the spring 3 of control clip folding; One end of its clip pencil is less than the tail end of mounting spring; The spring 3 of controlling spacing clip folding turns to the ring-spring card for known spring steel wire by spacing clip tail end shape making and at mounting spring bearing pin place, center.

The described pen cap 4 is the open circles cylindricality circle cover that a thin material is made.

The inner surface of the described pen cap 4 can be made into the ripple that increases coefficient of friction, also can make comparatively coarse inner surface.

The described pen cap 4 can be made by strong but pliable in texture thin plastics.

The described pen cap 4 is enclosed within nib one end of pencil 1 and exposes nib, and spacing card 2 is installed between two muscle of the pen cap 4.

Embodiment 1.

Spring 3 is stuck in the tail end of spacing clip 2, and bearing pin 5 passes in the annular aperture of spacing hole clipping and spring 3, and the two ends of bearing pin 5 are rivetted; The pen cap 4 is enclosed within the pen arm end of pencil 1 and exposes nib, grasp spacing card 2 tail ends also firmly, the front end of spacing card 2 is opened, spacing clip between two muscle of the pen cap 4, is unclamped spacing card 2, spacing card 2 just is fixed on the end of pencil.

The tail end of pot life position card 2 withstands on right hand tiger below and palm of the hand place, and the finger natural torsion is held a pen, and the distance of hand and nib is limited at optimal distance, makes whole health keep proper naturally.When needs sharpen a pencil or change pencil, firmly clutch the tail end of spacing card 2, unclamp spacing card 2, pencil is spurred downwards or withdraws from pencil get final product.
