Description

Hole pen difficult to grasp

Technical Field

The utility model relates to the field of school supplies, in particular to a hole pen which is not easy to grasp.

Background

The hole pen is a pencil with grooves on the surface, and has a round shape, a triangular shape and a hexagonal shape, so that the hole pen is convenient for a beginner to learn the pen holding posture or helps the beginner holding the pen incorrectly to correct the pen holding posture.

At present, some hole pens existing in the market are set to be elliptical, the cross section of a pen body of the hole pen is triangular, the elliptical concave depth is the same, and when a beginner uses the hole pen, the situation that the finger position of the beginner cannot be limited possibly exists, so that the pen holding posture of the beginner is wrong.

Disclosure of Invention

In order to solve the above problems, an object of the present utility model is to provide a hole pen which is not easy to grasp, and which can limit the finger position of a beginner and correct the pen-grasping posture.

In order to achieve the above object, the present utility model adopts the following scheme:

the utility model provides a hole pen that is difficult for holding mistake, includes, the pen body and pencil core, the inside of the pen body sets up pencil core, the pen body is the cylindricality body, the bottom surface of cylindricality body is the circle and lacks, forms arc surface and tangent plane two parts in the side of the pen body, the arc surface is equipped with the recess of a row equidistance equipartition respectively for tangent plane's both sides, mutual staggered arrangement between two rows of recesses, the recess internal surface is smooth cambered surface.

Preferably, the horizontal projection of the groove is one of oblique ellipse, positive ellipse, round or square, and four corners of the square are rounded corners. The modeling of the plurality of grooves can be adjusted and selected according to the preference of different children.

Preferably, the maximum depth of the groove is 1/4-1/2 of the radius of the round gap.

Preferably, the groove is arranged in the interval of 1/2-2/3 of the lower part of the pen body. The place without the groove is convenient to grasp, and the hand pencil sharpener has better force application point.

In summary, the utility model has the advantages that the utility model is provided with the shape of the arc surface and the tangential plane, the tangential plane is used for middle finger positioning, the groove on the arc surface is used for positioning the index finger and the thumb, the holding feeling is comfortable, the utility model accords with the human engineering, the holding gesture can be well corrected, and the holding mistake is not easy to be held.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In the description of the present application, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate an orientation or a positional relationship based on that shown in the drawings, merely for convenience of description and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.

The hole pen with the hard-to-grasp error as shown in fig. 1-4 comprises a pen body 1 and a pencil core 2, wherein the pencil core 2 is arranged in the pen body 1, the pen body 1 is a cylindrical body, the bottom surface of the cylindrical body is a circular gap, two parts of an arc surface 3 and a tangential plane 4 are formed on the side surface of the pen body, a row of grooves 5 which are uniformly distributed at equal intervals are respectively arranged on two sides of the arc surface 3 relative to the tangential plane 4, the grooves 5 are mutually staggered, and the inner surface of each groove 5 is a smooth arc surface.

As shown in fig. 1, the groove 5 is one of an ellipse, a circle or a square, and four corners of the square are rounded corners; the maximum depth of the groove 5 is 1/4-1/2 of the radius of the circular gap; the groove 5 is arranged in the interval of 1/2-2/3 of the lower part of the pen body 1.

The pen holding mode has the advantages that the index finger and the thumb are placed in the groove, the middle finger is placed on the tangential plane, the pen is comfortable to hold, the ergonomics are met, the pen holding posture can be quickly corrected, and the pen is not easy to hold by mistake.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art.
