Abstract
Description
Technical Field
[0001] This utility model relates to the field of pen technology, and in particular to a posture correction pen. Background Technology
[0002] Incorrect writing posture not only causes fatigue and unsightly handwriting in children, but can also lead to nearsightedness, pain and even deformity of the middle and index fingers, and affect the development of the wrist and spine, causing irreversible damage. The correct pen-holding posture should be as follows: the distal interphalangeal joint of the index finger should be straight; the thumb and index finger should lightly touch or slightly separate, with the thumb slightly higher than the index finger; the fingertips should be about 3 centimeters from the pen tip; the angle between the pen and the paper should be 45°–60°; the pen should rest diagonally against the base of the index finger, not against the web of the thumb and forefinger.
[0003] Currently, pen grip devices for correcting students' pen-holding posture have appeared on the market. However, these devices have complex structures, cannot conform to the standard pen-holding posture during use, and often require excessive force when writing, causing the pen to slide down continuously, making it difficult to ensure a correct pen-holding posture. Furthermore, there are currently no pen tools that guarantee a conformity to the standard pen-holding posture. Therefore, it is necessary to research a solution to address these problems. Summary of the Invention
[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a posture correction pen that can effectively solve the problem that existing pen grips cannot conform to the standard pen grip posture.

The pen core is located at the front end of the middle section, the pen tube is located at the rear end of the middle section, and the button cap is located at the rear end of the pen tube. The protective sleeve is fitted over the middle section and clamped between the middle section and the pen tube. The protective sleeve has a triangular cross-section, and its outer surface is recessed with a thumb recess, an index finger recess, and a middle finger recess. The thumb recess, index finger recess, and middle finger recess are located on the three outer surfaces of the protective sleeve. The drop h1 between the lowest points of the thumb recess and the index finger recess is 1.5–2 mm, and the drop h1 between the lowest points of the middle finger recess and the index finger recess is 5.5–6 mm.
[0007] Preferably, the thumb recess is formed by a first contact surface and a first limiting surface.
[0008] Preferably, the index finger recess is formed by a second contact surface and a second limiting surface.
[0009] Preferably, the middle finger recess is an elliptical recess.
[0010] Preferably, the middle section has an outer wall surface, and the sheath has an inner wall surface, which is in contact with the outer wall surface.
[0011] Preferably, the outer wall surface is provided with an anti-rotation rib, and correspondingly, the inner wall surface is provided with an anti-rotation groove, and the anti-rotation rib is embedded in the anti-rotation groove.
[0012] Preferably, the lower end of the middle section has a blocking surface, and the lower end surface of the sheath is an abutting surface, which is in contact with the blocking surface.
[0013] Preferably, the upper end of the middle section has an external thread section, and the lower end of the pen tube has an internal thread section, which are screwed together and fixed to the external thread section.
[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:
[0015] By placing the protective sleeve over the middle section and clamping it between the middle section and the pen barrel, and by providing thumb, index finger, and middle finger recesses on the outer surface of the sleeve, the thumb, index finger, and middle finger are positioned to effectively limit the child's grip position. Furthermore, the drop h1 between the lowest points of the thumb and index finger recesses is 1.5–2 mm, and the drop h1 between the lowest points of the middle and index finger recesses is 5.5–6 mm, which better conforms to the standard pen grip posture and can better correct the pen grip posture.
