Description

Technical Field

[0001] The utility model relates to the field of stationery, in particular to an extendable right-hand pen holder. Background Art

[0002] As an indispensable writing tool, the correct pen holding posture is very important, especially for children who have not yet formed the habit of holding a pen. The wrong pen holding posture will not only make children feel tired, affect the speed and standardization of writing, but also cause myopia, pain and even deformation of the middle and index fingers, affect the development of the wrist and spine, and cause irreversible damage. In order to solve the above problems, a pen holder for correcting the pen holding posture has been developed.

[0003] At present, most of the pen holders on the market are made of soft rubber materials such as rubber and silicone with high elasticity. The outer periphery of the pen holder is provided with grooves corresponding to the thumb, index finger and middle finger, as shown in Chinese utility model patents CN202986460U and CN201693890U. However, the diameter of the through hole in the middle of this type of pen holder is usually smaller than the outer diameter of the pen. The pen holder relies on its own elastic deformation to be tightly mounted on the outside of the pen. When the user's three fingers are not correctly placed in the corresponding grooves, the pen can still write normally, making it difficult to ensure that the user's three fingers are placed in the correct position, and the pen holding posture correction effect is not good.

[0004] Moreover, when the pencil is sharpened halfway, it is often not long enough to easily fall out of the thumb and cannot be used anymore, which shortens the service life of the pencil and causes certain waste.

[0005] Therefore, the present invention provides an extendable right-hand pen holder to solve the above-mentioned problems. Utility Model Content

[0006] The utility model aims to solve the technical problems of poor pen-holding posture correction effect and short pencil service life of the prior art pen-holding devices, and proposes an extendable right-hand pen-holding device.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A right-hand extendable pen holder comprises a gripping portion and an extension portion detachably connected to the upper end of the gripping portion, wherein the gripping portion and the extension portion are both provided with a through hole for inserting an external pencil in the middle, and a gap is provided between the inner wall of the through hole and the outer wall of the external pencil; the outer wall of the gripping portion is provided with a thumb recess, an index finger recess and a middle finger recess in sequence along the circumferential direction, and a clamping piece is detachably provided in the gripping portion, and the clamping piece comprises a thumb spring piece, an index finger spring piece and a middle finger spring piece arranged in sequence along the circumferential direction; a first through hole is provided in the thumb recess for the thumb spring piece to protrude outward, a second through hole is provided in the index finger recess for the index finger spring piece to protrude outward, and a third through hole is provided in the middle finger recess for the middle finger spring piece to protrude outward; the thumb spring piece, the index finger spring piece and the middle finger spring piece can clamp the external pencil under the action of an external force.

[0009] Furthermore, the length of the thumb recess and the length of the index finger recess are both greater than the length of the middle finger recess; the length of the thumb spring piece and the length of the index finger spring piece are both greater than the length of the middle finger spring piece.

[0010] Furthermore, the clamping member also includes a fixing ring, and the thumb spring piece, the index finger spring piece and the middle finger spring piece are sequentially arranged on the upper end of the fixing ring along the circumferential direction.

[0011] Furthermore, the inner and outer surfaces of the thumb spring piece, the index finger spring piece and the middle finger spring piece are all provided with anti-slip grooves.

[0012] A hollow baffle is provided at the lower end of the gripping portion, and protrusions are respectively provided at the positions of the thumb recess, the index finger recess and the middle finger recess on the inner wall of the gripping portion; a receiving groove is formed between the lower ends of the three protrusions and the hollow baffle, and the fixing ring is installed in the receiving groove.

[0013] Furthermore, the upper ends and lower ends of the three protrusions are respectively provided with guiding inclined surfaces.

[0014] Furthermore, the upper end of the gripping portion is provided with an internal thread, and the lower end of the extension portion is provided with an external thread matching the internal thread.

[0015] Furthermore, the inner diameter of the extension portion increases gradually from top to bottom.

[0016] Furthermore, a plurality of clamping protrusions are provided on the inner wall of the upper end portion of the extension portion along the circumferential direction.

[0017] Furthermore, the gripping portion and the extending portion are both made of hard plastic.

[0018] The beneficial effects of the utility model are as follows:

[0019] (1) There is a gap between the inner wall of the avoidance through hole in the gripping part and the extension part and the outer wall of the external pencil, and the gripping part and the extension part do not generate a clamping force on the external pencil. When the user holds the pen incorrectly or uses the left hand to hold the pen, at this time, the thumb, index finger, and middle finger of the user's right hand are at least partially not placed on the outer surface of the thumb spring sheet, the index finger spring sheet, and the middle finger spring sheet, and the thumb spring sheet, the index finger spring sheet, and the middle finger spring sheet cannot be pressed at the same time, and the clamping force on the external pencil is weak. At this time, if writing is performed, the external pencil will retract into the inside of the pen holder due to the force on the pen tip, so that the user cannot write when the pen holding posture is incorrect or the left hand is used to hold the pen, thereby forcing the user to use the right hand and the correct pen holding posture to write, thereby cultivating the user's correct pen holding posture and achieving the technical effect of correcting the user's pen holding posture;

[0020] (2) The upper end of the gripping portion is detachably connected to an extension portion. When the external pencil is short and easily slips out of the base of the thumb, the extension portion can be installed. Since the extension portion is made of hard plastic and has a certain hardness, the extension portion can be placed against the base of the thumb of the user. With this arrangement, even if the external pencil is short, the pencil holder in this embodiment can still be used normally, thereby extending the service life of the external pencil and saving resources.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0034] like Figures 1 to 10 As shown, the utility model provides an extendable right-hand pen holder, comprising a grip portion 1, and an extension portion 3 detachably connected to the upper end of the grip portion 1, wherein the grip portion 1 and the extension portion 3 are both provided with an escape hole 9 for inserting an external pencil 4, and a gap is provided between the inner wall of the escape hole 9 and the outer wall of the external pencil 4; the outer wall of the grip portion 1 is sequentially provided with a thumb recess 5, an index finger recess 6 and a middle finger recess 7 along the circumferential direction, and a clamping member 2 is also detachably provided in the grip portion 1, so that The clamping member 2 comprises a thumb spring piece 21, an index finger spring piece 22 and a middle finger spring piece 23 which are sequentially arranged along the circumferential direction; a first through hole 51 is provided in the thumb recess 5 for the thumb spring piece 21 to protrude outward, a second through hole 61 is provided in the index finger recess 6 for the index finger spring piece 22 to protrude outward, and a third through hole 71 is provided in the middle finger recess 7 for the middle finger spring piece 23 to protrude outward; the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 can clamp the external pencil 4 under the action of external force.

[0035] In actual use, preferably, the gripping portion 1 and the extension portion 3 are both made of hard plastic. Since the gripping portion 1 and the extension portion 3 are not elastic, the avoidance through hole 9 in the gripping portion 1 and the extension portion 3 is set to be larger than the size of the external pencil 4, that is, there is a gap between the inner wall of the avoidance through hole 9 and the outer wall of the external pencil 4, so that the external pencil 4 is easily inserted into the avoidance through hole 9; and a clamping member 2 is provided in the gripping portion 1, and the clamping member 2 is provided with a thumb spring piece 21, an index finger spring piece 22 and a middle finger spring piece 23 along the circumferential direction. Specifically, the outer surfaces of the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 extend from the first through hole 51, the second through hole 61 and the third through hole 71 to the outside. The thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 are convex outward, and the setting positions of the thumb, index finger and middle finger are the placement positions of the thumb, index finger and middle finger when the right hand holds the pen, so that the thumb, index finger and middle finger of the user's right hand can contact the outer surfaces of the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 respectively; when the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 are not subjected to external force, the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 just contact the outer wall of the external pencil 4, that is, at this time, the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 have a weak clamping force on the external pencil 4 so that the external pencil 4 will not fall off from the pen holder without the action of external force. When in use, when the user holds the pen correctly, the thumb, index finger and middle finger of the user's right hand contact the outer surfaces of the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 respectively and exert force to increase the clamping force of the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 on the external pencil 4, thereby preventing the external pencil 4 from retracting into the pen holder due to the force when writing; when the user holds the pen incorrectly or uses the left hand to hold the pen, at this time, the thumb, index finger and middle finger of the user's right hand are at least partially not placed on the outer surfaces of the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23. The thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 cannot be pressed at the same time. At this time, the clamping force on the external pencil 4 is weak, and the gripping portion 1 and the extension portion 3 do not generate clamping force on the external pencil 4. If writing is performed at this time, the external pencil will retract into the inside of the pen holder due to the force on the pen tip, so that the user cannot write when holding the pen with the wrong posture or holding the pen with the left hand, thereby forcing the user to use the right hand and adopt the correct pen holding posture to write, thereby cultivating the user's correct pen holding posture and achieving the technical effect of correcting the user's pen holding posture.

[0036] In addition, the upper end of the gripping portion 1 is detachably connected with an extension portion 3. When the external pencil 4 is short and easily slips out of the base of the thumb, the extension portion 3 can be installed. Since the extension portion 3 is made of hard plastic and has a certain hardness, the extension portion can be placed on the base of the thumb of the user. With this arrangement, even if the external pencil 4 is short, it can still be used normally through the pen holder in this embodiment, thereby extending the service life of the external pencil 4 and saving resources.

[0037] Furthermore, the length of the thumb recess 5 and the length of the index finger recess 6 are both greater than the length of the middle finger recess 7; the length of the thumb spring piece 21 and the length of the index finger spring piece 22 are both greater than the length of the middle finger spring piece 23. In this embodiment, since the contact area between the thumb and index finger and the pen holder is larger when holding a pen, and the contact area between the middle finger and the pen holder is smaller, the length of the thumb recess 5 and the index finger recess 6 are both set to be greater than the length of the middle finger recess 7, and the length of the thumb spring piece 21 and the index finger spring piece 22 are both set to be greater than the length of the middle finger spring piece 23, so that the thumb or index finger cannot be placed at the position of the middle finger recess 7, further ensuring that the three fingers of the user are placed in the correct position when using, thereby achieving a better correction effect.

[0038] Furthermore, the clamping member 2 further comprises a fixing ring 24, and the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 are sequentially arranged along the circumferential direction at the upper end of the fixing ring 24. In this embodiment, by providing the fixing ring 24, on the one hand, the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 can be fixed, and on the other hand, the middle part of the fixing ring 24 can facilitate the passage of the external pencil 4.

[0039] Furthermore, the inner and outer surfaces of the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23 are all provided with anti-skid patterns 25. In this embodiment, by providing the anti-skid patterns 25 on the inner surfaces of the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23, the friction between the inner surfaces of the three spring pieces and the outer wall of the external pencil 4 is increased. When in use, as long as the pen is held in the correct position, the user does not need to use much strength, and the three spring pieces can clamp the external pencil 4; by providing the anti-skid patterns 25 on the outer surfaces of the thumb spring piece 21, the index finger spring piece 22 and the middle finger spring piece 23, the friction between the outer surfaces of the three spring pieces and the three fingers is increased, preventing the fingers from slipping between the pen holder during writing.

[0040] Furthermore, a hollow baffle plate 11 is provided at the lower end of the gripping portion 1, and protrusions 8 are provided at the positions of the inner wall of the gripping portion 1 corresponding to the thumb recess 5, the index finger recess 6 and the middle finger recess 7; a receiving groove 12 is formed between the lower ends of the three protrusions 8 and the hollow baffle plate 11, and the fixing ring 24 is installed in the receiving groove 12. In this embodiment, the protrusions 8 are provided to enhance the strength of the thumb recess 5, the index finger recess 6 and the middle finger recess 7, so that they are not easily damaged under the action of external forces, and the receiving groove 12 is provided so that the fixing ring 24 in the clamping member 2 can be installed in the receiving groove 12, thereby effectively preventing the clamping member 2 from falling off from the gripping portion 1.

[0041] Furthermore, the upper and lower ends of the three protrusions 8 are respectively provided with guide slopes 81. In this embodiment, by providing the guide slopes 81, it is convenient for the clamping member 2 to smoothly enter the interior of the gripping portion 1 during installation.

[0042] Furthermore, the upper end of the gripping portion 1 is provided with an internal thread 13, and the lower end of the extension portion 3 is provided with an external thread 31 matching the internal thread 13. In this embodiment, the gripping portion 1 and the extension portion 3 are connected by threads, which facilitates the disassembly and assembly of the extension portion 3.

[0043] Furthermore, the inner diameter of the extension part 3 increases from top to bottom; preferably, the inner wall of the upper end of the extension part 3 is provided with a plurality of clamping protrusions 32 along the circumferential direction. Specifically, there are three clamping protrusions 32 and they are evenly arranged along the circumferential direction, and the clamping protrusions just contact the outer wall of the external pencil 4. When the thumb spring piece 21, the index finger spring piece 22, and the middle finger spring piece 23 are not subjected to force, in addition to the thumb spring piece 21, the index finger spring piece 22, and the middle finger spring piece 23 having a weak clamping force on the external pencil 4, the clamping protrusions 32 also have a weak clamping force on the external pencil 4, further ensuring that the external pencil 4 will not fall off from the pencil holder without the action of external force.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
