Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

Example 1

Referring to fig. 1, the curved writing pen comprises a pen holder 1, wherein the middle of the pen holder 1 is curved, the pen holder 1 is divided into a front rod section 12 and a rear rod section 11 from the front to the rear of the curved part, and an included angle between the front rod section 12 and the rear rod section 11 is an obtuse angle.

Specifically, the length ratio of the front rod section 12 to the rear rod section 11 is 1: 1-1.5: 1.

Specifically, the included angle between the front rod section 12 and the rear rod section 11 is 160-170 °.

Concretely, still include nib 3 and tail-hood 2, seted up the open black passageway 5 that holds in both ends along its extending direction in the pen-holder 1, nib 3 sealing connection is located the uncovered of preceding pole section 12 tip in pen-holder 1, and tail-hood 2 sealing connection is located the uncovered of back pole section 11 tip in pen-holder 1.

Specifically, the ink containing passage 5 has a circular cross section.

When the penholder 1 is held, the rear rod section 11 faces the direction away from the tiger mouth, so that the gravity center of the penholder 1 moves forwards, the pinching force required by holding the posture is reduced, the compression on the side wall of the middle finger joint is reduced, the holding fatigue is effectively relieved, the writing efficiency is improved, and the possibility of deformity of the middle finger joint is reduced.

Example 2

Referring to fig. 2 to 4, the difference from embodiment 1 is: the cross section of the penholder 1 is in a Leluo triangle shape.

Specifically, an arc transition groove 4 is formed in the inner side of the bent part of the pen holder 1, and the arc transition groove 4 is located on one of three ridge edges of the pen holder 1.

The pen holder 1 with the cross section in the shape of a Leluo triangle is used for correcting the pen holding posture of a user, so that the user is prompted to develop a habit that the thumb, the index finger and the middle finger respectively press three arc-shaped surfaces of the pen holder 1 and are not in contact with each other to pinch the pen holder 1, the rear rod section 11 faces to a position far away from a tiger mouth when the user holds the pen, the pinching force required by the holding posture maintaining is reduced, the compression on the side wall of the middle finger joint is avoided, the pen holding fatigue is relieved, the writing efficiency is improved, and the middle finger joint is effectively prevented from being; in addition, when a user develops a habit of pressing the three arc-shaped surfaces of the pen holder 1 by the thumb, the forefinger and the middle finger respectively without contacting each other to knead the pen holder 1, the arc-shaped transition groove 4 is close to the lateral wall of the root of the forefinger finger, although the gravity center moves backwards, the gravity center of the pen holder 1 with the old pen holding habit of the user can be simulated, and therefore the effect of transition of the new and old pen holding habits of the user is achieved.

In particular, according to example 2, the applicant advocated a scientific and healthy writing posture: 1. the penholder 1 is close to the side wall of the forefinger instead of the tiger mouth; 2. the thumb, the forefinger and the middle finger are adopted to respectively press the three arc-shaped surfaces of the penholder 1 and are not contacted with each other so as to knead the penholder 1; 3. the thumb, the index finger and the middle finger are naturally bent, and the penholder 1 is lightly held; 4. the ring finger and little finger are naturally bent and contracted.
