Abstract

The utility model belongs to the writing tool class. The multifunctional health-care mobile pencil is developed primarily for correcting the incorrect writing posture of children; a big spring which bears the writing force is added in the pencil; through the rotation of the pencil hanging, a core storing tube drives the limiting piece to rotate to regulate the writing physical strength; at the time of writing, if the writing postures of the children are incorrect, the lead core can automatically retract and the children can not write; if the correct writing posture is corrected and then adopted, any component of the pencil need not to be adjusted to normally and easily write. The utility model has the advantages of low manufacture cost, a rubber, a knife blade, and a pencil as integration, one-time forming of sharpening core, convenient operation and portability, and fluent writing.

Description

Multifunctional health-care mobile pencil

The utility model belongs to the writing implement class.

The utility model is an improved new product on the basis of pulsating propelling pencil; although propelling pencil has obtained using at large in children; but because everyone writing physical strength difference; thereby regular meeting fractureing of lead for retractable pencil occur or shrinks back phenomenon; also exist simultaneously lead for retractable pencil skiving, wipe the carrying of word and pencil, inconvenient problem with use, also do not have a kind of propelling pencil can by correct the juvenile askew, the incorrect writing posture that writes on all fours prevents myopia and rickets effectively.

The purpose of this utility model is to provide a kind of exactly can overcome above-mentioned shortcoming, corrects juvenile's incorrect writing posture, can adjust writing physical strength, cuts the core one-shot forming, portably uses multi-function health-care propelling pencil easily.

In order to achieve the above object, feature in utility model is that penholder (3) inner chamber is equipped with big spring (2), the two ends of big spring (2) contact with little spring cover (1) and locating part (4) respectively, locating part (4) and pen hanging (6) form stationary fit with core storage tube (5) respectively, the internal thread of the external screw thread of locating part (4) and penholder (3) links, press that head (8) is gone up and four blades of blade (9) between corresponding position, space have through hole.

Big spring (2) is a compression spring.

Four blades of blade (9) are positioned on the surface of same cone, and its blade and the distance of pressing between the rotation of head (8) increase gradually along the cutting direction of blade (9).

The endoporus of locating part (4) can be triangle endoporus or polygon endoporus, and the core storage tube that matches with it (5) correspondingly is tri-prismoid or multiedge cylinder.

The utility model low cost of manufacture is write the Shi Buhui lead for retractable pencil that fractures, and can adjust writing physical strength, cuts the core one-shot forming, portably uses conveniently, and fluent writing helps the juvenile to correct incorrect writing posture, can effectively prevent myopia and rickets.

Do step explanation below in conjunction with accompanying drawing:

Description of drawings: Fig. 1 is an installation diagram of the present utility model

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

Fig. 3 is the B-B cutaway view of Fig. 1

As seen from the figure, on the core storage tube (5) in the penholder (3) big spring (2) is housed, the two ends of big spring (2) contact with little spring cover (1) and locating part (4) respectively, core storage tube (5) is a four prisms cylinder, the quadrangle endoporus of itself and locating part (4) and pen hanging (6) forms stationary fit, and the internal thread of the external screw thread of locating part (4) and penholder (3) links.

The inner chamber of pressing head (8) is equipped with blade (9) and rubber (7), the method for making of blade (9) is that stalloy that a block length is square is earlier to folding up, and be screwed after forming certain angle, have V-notch in the middle part of its openend again, its indentation, there is blade, this blade (9) has four blades, be positioned on the surface of same cone, its blade and the distance of pressing between the rotation of head (8) increase gradually along the cutting direction of blade (9), and the corresponding position, space of pressing between four blades of the top of head (8) and blade (9) has through hole.

In use, press and press head (8) and can make lead for retractable pencil output, stop to press, lead for retractable pencil can be held.

Rotation pen hanging (6) can be passed through core storage tube (5) and drive locating part (4) rotation, thereby locating part (4) and little spring cover (1) are compressed big spring (2), reach the purpose of adjusting writing physical strength, increase if clockwise direction rotation pen hanging (6) can make lead for retractable pencil hold the multiple power of writing, otherwise then reduce.Big spring (2) bears the power of writing, and its elastic force is directly proportional with writing physical strength, and same writing physical strength is influenced by the angle of paper and pencil holder again.

Correct writing posture is that the angle of propelling pencil and paper is 50 °-60 °, at this moment lead for retractable pencil can bear the above power of writing of 100g, if posture is not right, sight line is not just, angle is increased, promptly use the same power of writing, lead for retractable pencil also can bounce back immediately and can't write, if correct and adopt correct writing posture, then needn't adjust any parts of pencil, can normally fluently write again, so just reach the purpose of the writing posture standard of emphasizing to require the juvenile, thereby effectively prevented myopia and rickets.

Take off if will press head (8), promptly available rubber (7) is wiped word, if the through hole of lead for retractable pencil on pressing head (8) inserted the space between four blades of blade (9), the rotation by lead for retractable pencil or blade (9) just can reach the one-time formed purpose of grinding lead for retractable pencil.
