Description of the new type: [Technical field to which the new type belongs] This creation belongs to the technical field of structural improvement of the bridge posture mechanical pen with the design of the force-applied arch plate design, especially the use of a positioning force board to make the index finger free It can be positioned at the end and can avoid holding the pen too far away from the tip of the pen. ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, angles, and the index finger, and the correct curvature, and easier movement . [Previous technique] Pressing the correct posture of holding the pen is to provide correctness. Generally, everyone only notices the thumb, she, and knife. The correct grip of this part of the middle and second fingers, and its associated effects, must be combined with a good force to achieve easy reading and writing. Because the average person writes 4 as shown in the picture of holding a blade, five eyes, etc., common mistakes such as the fifth picture A, the second finger often extends forward, and includes Γ. After the middle finger end abuts against the pen side, the thumb pen shaft Written Japanese Shishi W set and press the index finger tightly, this position is used to fix the flat inch, the thumb is closed ^ Thumb Η-and 'have been very hard to cause fatigue, and this sweet bait Zhiguan Lang's prominent bending Wan Chou's vision _ also took the risk of directly covering his eyes and staring at the nib, ni, and quan. And the sound must be, you must tilt your head, lower your head, and squint to see the big pressure. At this time, thumb,:. Clamp the pen with a strong force, the middle finger will also be strongly restricted, so you can only do small Fan II * middle three fingers are subject to motion distortion due to the tight grip gesture, and Zhong Bu said the movement 'and each of the fingers will produce pain over time . -The common pre-school age W-end joints will also feel pain due to the stress. It is not developed yet. In order to enable the control = the first child, the forefinger is too close to the pen because of the small muscle control ability. It is common for the thumb and the inside to cause the above-mentioned obscuration and sitting posture M280921 when holding the pen. This long-term crooked writing posture will cause children with poor development of the neck, 3 shoulders, spine, etc. Lasting, slow, and ultimately affect the interest in writing. Another commonly held and misunderstood gesture is that when writing, the thumb and forefinger should hold the pen to move and write. This type of thumb and forefinger grasp the pen and use the flexion and extension of the thumb and forefinger to move. The wrong way of writing with force is a serious violation of the principle of using the wrist to control the horizontal drawing. It also shortens the length of the lever arm of the lever from the palm to the wrist, resulting in slow writing and horizontal strokes. The range of writing exercises will also result in only small fonts. In addition, because it is not ergonomic, the writer can use this two-finger telescoping method to write the day and day, and will automatically adjust to the posture of the wrist arch tightly bent inward, which also causes the pen to lean forward. Effect, also cause extreme long-term fatigue or injury of the wrist, causing the entire writing posture to be deformed, which is not conducive to the result of writing! However, looking at the above-mentioned incorrect pen-holding postures, it is nothing more than φ that the palm is not hollow when the pen is held, and the fist or thumb is tightly gripped, which restricts the movement and range of the finger, and grasps the pen with the thumb and index fingertips Movement, causing the wrist to be unable to relax, nor to use the wrist to apply improper force such as horizontal drawing, these incorrect pen-holding postures often cause slow writing when writing, unable to easily write What's more, the result of being unable to write beautiful fonts and causing physical burdens such as sore hands, finger pain, and physical fatigue! Especially for children, if they develop the above common wrong pen-holding postures from an early age, they will feel that writing homework is a laborious and time-consuming and difficult task, except when writing homework, they will not be able to master the ease of writing. ， M280921 ·. Creates a bad impression of writing homework. ◦ Once it develops a fixed error from childhood, it will be more difficult to correct it after the habit of holding the pen and posture. It will affect one of them in the future. For this reason, it can be seen from the above that the posture of holding the pen used in practice is indeed lacking. The reason for this creator is to accumulate years of research and development and manufacturing experience in the field of writing teaching. Therefore, the common problems faced by the existing grip gestures are discussed and researched, and solutions are actively sought after repeated testing. After the improvement, this kind of mechanical pen structure design that can really improve all of the above-mentioned missing points has been created. [New content] For this reason, the main purpose of this creation is to provide an improved structure of the orthopaedic mechanical pen with the design of the arch of the designated position of the food, which can make the thumb, food, and middle three designated, and make the hand tiger mouth when holding the pen It can form a round shape of palm space, so that each finger can easily move and write, and relax the wrist, and can have the correct posture and forceful way to hold the pen. • Also, the second purpose of this creation is to provide an improved structure of the posture-correcting mechanical pen with a design of a board with a specified force, which can be used to hold the pen to write, which can better contribute to the vertical movement, allowing users to The effect of this structure can be used to increase the range of finger movement for easier and labor-saving writing. In order to achieve the above-mentioned purpose, the present invention provides an improved structure of an orthopaedic mechanical pen with a design of a force-applied arch plate at a specified position. When the hand is held while writing, the orthographic mechanical pen abuts against the thumb. A thumb positioning point is provided at the position, and a designated position is set at the abutment position of the posture correcting mechanical pen with respect to the middle finger. In addition, the orthopaedic mechanical pen is positioned at the abutment position with respect to the index finger. 7 M280921 ·· There is an index-position force arch plate with an appropriately increased thickness and an arc-shaped position. "The free end of the index finger is positioned and pressed against its angle, and The index finger forms a writing curve, which can form a round tiger's mouth, holding the pen in the palm of the hand, and avoiding the thumb and finger to be too close to the pen tip to achieve the correct posture of the pen. And by designing with an appropriately increased thickness, the index finger can be better Make a force and make a larger vertical movement. ◦ You can also avoid using the thumb and index finger to hold the pen to apply force. The height of the index finger will be slightly lower than that of the thumb. • The orthopedic mechanical pen may include a tube body and a pen body penetrating the tube, and the tube body is provided with a true and appropriate thickness arc-shaped force-designated arch plate at an abutting position relative to the index finger. With the free end of the forefinger, you can avoid holding the pen too close to the pen tip and leaning against it at an angle, which can make the indexer write a correct curvature, and feel that the index finger is more forceful, and the index finger is lower than the thumb, allowing the index finger Do better The force in the pressing direction of the vertical drawing means that the tube body can be a positioning member, and the positioning member is provided with an appropriately-designed eclipse application plate with an appropriately increased thickness at a position relative to the Φ for the free end of the index finger Positioning can avoid holding the pen too close to the pen tip and leaning against its angle, which can make the index finger form a correct writing curve, and the index finger will exert better force, and the index finger height will be slightly lower than the thumb, which will make the index better. In the daytime pressing direction, the thumb and middle fingers can be held at the positioning point when the pen is held, and the index finger is used to position the force arch, and the index finger is used to form a curvature of the index finger grip to allow use. It can form a palm-hole posture with a tiger's mouth in a round shape, and the thickness of the force chess board is 9 and can make the index finger easier to lighten by the principle of the crossbar for the correct consumption of the two arch boards. Fingers are arched, and the index finger loosens M280921 when the finger is held against the finger. It feels more comfortable when holding the pen and the book. The finger is firmly held at ^-Mingli, which can also prevent the user.

The indexing force arch (1 3) of the index finger is used for positioning the free end of the index finger and can avoid holding the pen too close to the pen tip and leaning against it at an angle, so that the index finger can form a correct writing curve, and the index finger can be more effective when writing. Good output, and the index finger's height is lower than the thumb, so that the index finger can perform better repairing force operation in the vertical pressing direction. Among them, please refer to the fourth figure, the tube body (20) can be a positioning member ( 30), the positioning member (30) is provided with a forefinger position force arch plate (13) with an appropriately increased thickness in an arc shape relative to the top position of the index finger for positioning the free end of the index finger and avoiding the distance of holding the pen The pen tip is too close and leans against its angle, which can make the index finger form a correct writing curve, and feel that the index finger exerts more force, and the index finger is lower than the thumb, so that the index finger can make a better vertical drawing. Press the direction For the practical application of this creation, please cooperate As shown in the first and second figures, when using the orthotics pen (1 0), the thumb is first pressed against the thumb positioning point (11), the middle finger is pressed against the designated position (1 2), and the index finger is pressed. Lean on the indexing force arch (1 3), and then press the third joint of the index finger at the tiger's mouth against the orthotics pen (1 0). At this time, the arc of the indexing force arch (1 3) gives With the forefinger resting on the back, it will naturally form a correct writing curve, and can avoid holding the pen too close to the pen tip, while making the tiger's mouth round, forming a palm-empty state, and guiding the gripping posture mechanical pen (1 〇) pen body according to this bevel angle The homeopath relies on the tiger's mouth 10 M280921 • The third index finger abuts, and the height of the index finger will be lower than the thumb at this time. Reach the correct grip. As a result, the index plate (1 3) has a proper fox degree due to the index position, which can form a correct writing curve when the index finger is held, and can avoid holding the pen too close to the pen tip and forming a palm-free state, and the hand The correct posture of the pen can be achieved by holding the orthopaedic mechanical pen (1 0) in place, which prevents the user's thumb from being forced and held tight, causing the thumb joint to protrude and obscure writing ® sight , Thereby preventing users from squinting and squinting their heads. It can also prevent muscle fatigue, sore fingers, etc. caused by each finger being squeezed, or the result of poor movement of finger writing, and it can make the index finger work better.
