[0002] At present, a considerable number of students have the phenomenon of incorrect pen-holding posture, and long-term incorrect pen-holding posture is likely to cause problems such as finger deformation, myopia, strabismus, hunchback or spinal deformity. Therefore, how to guide and train children to use the correct pen-holding posture to write has become one of the issues that parents and teachers are very concerned about. At this time, pen holders used to correct children's pen-holding habits or assist children in accurately exerting force have gradually entered the stationery market. Among them, there is a type of pen holder that prompts the user to better position the thumb, index finger and middle finger by setting three adjacent concave surfaces, so that the user knows the correct placement of the three fingers when holding the pen. This type of pen holder has a certain guiding role, but it hardly plays a role in how to guide children to exert force accurately. Furthermore, the use of existing pen holders is to insert the pen into the through hole of the pen holder, and set a related structure to fix the pen body to prevent the relative sliding of the pen holder and the pen body, so that the user can better grasp the pen holder, but this type of structural design is more unfavorable for the user to master the degree of force exerted on the pen holder.
[0003] Based on the above problems, the present invention improves the relevant structure of the pen holder in terms of how to improve the user's control over the degree of force exerted by the pen holder. Summary of the invention
[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a pen grip corrector that can accurately control the pen grip force.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Furthermore, a surface of the third positioning protrusion in contact with the pencil body is a plane, and the plane is parallel to an inner wall of the concave surface of the pen-holding sleeve corresponding to the middle finger.
[0008] Furthermore, the width of the second positioning protrusion is smaller than the width of the first positioning protrusion.
[0009] Furthermore, the cross-sectional shape of the through hole is a rounded triangle.
[0010] Furthermore, the concave surface of the thumb and the concave surface of the index finger are both provided with friction and anti-slip patterns.
[0011] Furthermore, the distance from the middle finger concave surface to the index finger concave surface along the outer circumference of the pen-holding sleeve is smaller than the distance from the middle finger concave surface to the thumb concave surface along the outer circumference of the pen-holding sleeve.
[0012] Furthermore, the distance from the center of the first positioning protrusion to the center of the third positioning protrusion along the circumference of the inner wall of the pen holding sleeve is greater than the distance from the center of the second positioning protrusion to the center of the third positioning protrusion along the circumference of the inner wall of the pen holding sleeve.

DETAILED DESCRIPTION
[0022] In order to facilitate the understanding of those skilled in the art, the following embodiments and attached Figure 1-5 To further illustrate the present invention, the contents mentioned in the implementation modes are not intended to limit the present invention.
[0023] Example 1
[0024] like Figure 1-4 As shown, the present embodiment provides a pen grip corrector for accurately controlling the pen gripping force, comprising a pen grip sleeve 1, wherein the pen grip sleeve 1 is axially penetrated with a through hole 2 for inserting a pencil 11, and the outer wall of the pen grip sleeve 1 is circumferentially adjacently provided with a thumb concave surface 3, an index finger concave surface 4 and a middle finger concave surface 5, and the inner wall of the pen grip sleeve 1 is respectively provided with a first positioning protrusion 6, a second positioning protrusion 7 and a third positioning protrusion 8 corresponding to the positions of the thumb concave surface 3, the index finger concave surface 4 and the middle finger concave surface 5, wherein the first positioning protrusion 6 and the second positioning protrusion 7 are in contact with the body of the pencil 11 on a curved surface, and a gap is provided between the outer wall of the body of the pencil 11 and the inner wall of the pen grip sleeve 1.
[0025] In this embodiment, there is a gap between the inner wall of the pen-holding sleeve 1 and the outer wall of the pencil 11 body, that is, the pen-holding corrector and the pencil 11 are in a gap fit, which is different from the tight fit structure between most existing pen-holding devices and pencils 11. The pen-holding corrector of the utility model mainly contacts the pencil 11 body through the first positioning protrusion 6, the second positioning protrusion 7 and the third positioning protrusion 8 arranged inside, so as to prevent the pencil from sliding freely or disengaging relative to the pen-holding sleeve 1 when not in the writing state. When in use, the user needs to pinch the thumb concave surface 3 and the index finger concave surface 4 with the thumb and index finger respectively, and the first joint of the middle finger naturally abuts against the middle finger concave surface 5, thereby determining the correct pen holding position. Since the pen-holding sleeve 1 and the pencil 11 are in a gap fit, the user needs to hold the pen-holding sleeve 1 with a little force to ensure that the pencil 11 will not slide or disengage relative to the pen-holding sleeve 1. At this time, the first positioning protrusion 6, the second positioning protrusion 7 and the third positioning protrusion 8 are in close contact with the three sides of the pencil 11 body respectively to fix the pencil 11. When the user's finger force is too small, the pen-holding sleeve 1 cannot stably hold the pencil 11; when the user's thumb, index finger or middle finger exerts too much force, the contact surface between the first positioning protrusion 6 or the second positioning protrusion 7 and the pencil 11 body will be offset due to excessive squeezing of the pen-holding sleeve 1 and the first positioning protrusion 6 or the second positioning protrusion 7, and the pencil 11 cannot be stably held at this time. Therefore, only when the user's thumb, index finger and middle finger form a suitable angle with each other and exert force accurately can the pen be stably held for writing. In addition, the middle finger also plays the role of triangular support and stable support. When the pen-holding corrector is in the correct pen-holding posture, the rear end of the pencil 11 body naturally rests on the base of the user's index finger, restoring the pen-holding feeling to the greatest extent.
[0026] Furthermore, the surface of the third positioning protrusion 8 in contact with the pencil 11 body is a plane, and the plane is parallel to the inner wall of the middle finger concave surface 5 corresponding to the pen-holding sleeve 1. The plane of the third positioning protrusion 8 can better fit the pencil 11 body.
[0027] Furthermore, the width of the second positioning protrusion 7 is smaller than the width of the first positioning protrusion 6 .
[0028] Specifically, the width refers to the circumferential distance from one end of the first positioning protrusion 6 or the second positioning protrusion along the inner wall of the pen-holding sleeve 1 to the other end. In this embodiment, the ratio of the width of the second positioning protrusion 7 to the width of the first positioning protrusion 6 is about 1:2. Since the contact surface between the thumb and the pen-holding sleeve 1 is large, increasing the width of the first positioning protrusion 6 can make the contact between the first positioning protrusion 6 and the pencil 11 body more stable, which helps to improve the stability of pen holding.
[0029] Furthermore, the cross-sectional shape of the through hole 2 is a rounded triangle.
[0030] Furthermore, the thumb concave surface 3 and the index finger concave surface 4 are both provided with friction anti-skid patterns 9. The provision of the friction anti-skid patterns 9 can increase the contact friction between the thumb and the thumb concave surface 3, and between the index finger and the index finger concave surface 4, so that the thumb and the index finger can stably grasp the pen holder 1.
[0031] Furthermore, the distance from the middle finger concave surface 5 to the index finger concave surface 4 along the outer circumference of the pen holding sleeve 1 is smaller than the distance from the middle finger concave surface 5 to the thumb concave surface 3 along the outer circumference of the pen holding sleeve 1 .
[0032] Furthermore, the distance from the center of the first positioning protrusion 6 to the center of the third positioning protrusion 8 along the circumference of the inner wall of the pen holding sleeve 1 is greater than the distance from the center of the second positioning protrusion 7 to the center of the third positioning protrusion 8 along the circumference of the inner wall of the pen holding sleeve 1.
[0033] In this embodiment, when the pen grip corrector is in use, the relative positions of the thumb concave surface 3, the index finger concave surface 4 and the middle finger concave surface 5 are set so that the thumb and the middle finger of the user are naturally separated when holding the pen, so as to better grasp and exert force; and the contact between the first positioning protrusion 6 and the second positioning protrusion 7 and the body of the pencil 11 can prevent the deviation of the pen grip sleeve 1, thereby ensuring that the user's pen holding posture is correct and maintains a suitable pen holding force. When the user can hold the pen correctly, his line of sight can clearly see the tip of the pencil 11, which can correct bad sitting postures such as sitting sideways, tilting the head, squinting or hunching formed by the incorrect pen holding posture blocking the tip.
[0034] Furthermore, a decorative piece 10 is provided at one end of the pen-holding sleeve 1 away from the writing end. In this embodiment, the pen-holding sleeve 1 is designed in the shape of a dolphin, which increases the appearance interest of the pen-holding corrector.
[0035] Furthermore, the pen grip sleeve 1, the first positioning protrusion 6, the second positioning protrusion 7 and the third positioning protrusion 8 are all made of elastic material by integrally processing and molding. Specifically, the elastic material can be a rubber material or a silicone material in the prior art, and the rubber material or the silicone material is integrally molded in a specific mold through a glue injection process. The pen grip corrector made of elastic material can improve the user's pen grip comfort.
[0036] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
