Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of correcting pen-holding posture, and more specifically, to a tool for correcting pen-holding posture. Background Art
[0002] Nowadays, many children always fail to achieve the standard pen holding posture when they first start learning to write. After forming the habit of irregular writing posture for a long time, not only will the handwriting be irregular and the strokes not smooth, but incorrect pen holding will also affect the sitting posture when writing, easily leading to hunchback, myopia, etc., seriously affecting the normal physical development of children.
[0003] In order to solve the above problems, many businesses have developed a variety of pen holders in the hope of helping to develop a correct pen holding posture, but the results are not ideal. The reason is that most businesses only pay attention to whether the static pen holding action formed between the index finger, middle finger and thumb (referred to as: three fingers holding the pen) and the pen shaft is correct, but ignore that writing itself is a dynamic activity rather than a static posture. Even if the pen holding action formed by the relative positions and angles of the three fingers holding the pen and the pen shaft are correct, it is impossible to guarantee the dynamic writing process. Whether there will be dynamic offset between the three fingers holding the pen and the pen shaft will cause the writing action to be deformed invisibly and cannot be detected. Utility Model Content

[0024] The following is combined with Figure 1-3 The utility model is described in further detail.
[0025] See also Figure 1-3 The utility model provides a technical solution: a tool for correcting pen holding posture, comprising an outer tube 1, two limit rods 2 are fixedly connected to the inner wall of the outer tube 1, an inner tube 3 is slidably connected to the inner wall of the outer tube 1, two limit grooves 4 are arranged on the surface of the inner tube 3, the inner tube 3 is slidably connected to the surfaces of the two limit rods 2 through the two limit grooves 4, the lower end of the outer tube 1 and the upper end of the inner tube 3 are respectively fixedly connected with a clamping assembly 5, the clamping assembly 5 comprises a clamping head 501, a plurality of notches 502, a tapered thread 503 and a threaded cap 504, and the inner wall of the outer tube 1 and the inner wall of the inner tube 3 are both plugged with a pen body 6. A plurality of indicating grooves 7 are provided on the surface of the outer tube 1, and indicating protrusions 8 are provided on the inner walls of the plurality of indicating grooves 7 respectively. By providing the indicating grooves 7 and indicating protrusions 8, dynamic offset between the three fingers holding the pen and the pen holder can be prevented to affect the correction process. By providing the clamping assembly 5, the threaded cap 504 drives the clamping head 501 to clamp the pen bodies 6 of different diameters. The inner tube 3 slides on the inner wall of the outer tube 1, so as to facilitate the clamping of notes of different lengths. By providing the limiting rod 2 and the limiting groove 4, the rotation of the inner tube 3 is limited.
[0026] Specifically, the clamping head 501 is fixedly connected to the lower end of the outer tube 1, and multiple notches 502 are opened on the surface of the clamping head 501. The surface of the clamping head 501 is provided with a tapered thread 503 and a tapered surface. The surface of the clamping head 501 is threadedly connected with a threaded cap 504 through the tapered thread 503.
[0027] By adopting the above technical solution, by rotating the threaded cap 504, the clamping head 501 is contracted under the action of the tapered thread 503 and the notch 502, so as to clamp the pen body 6 with different diameters.
[0028] Specifically, inner walls of the plurality of indicator grooves 7 are all provided with rubber pads.
[0029] By adopting the technical solution and arranging the rubber pad, the comfort of writing is improved.
[0030] Specifically, the surfaces of the two threaded caps 504 are respectively provided with anti-slip grooves 9, and the outer tube 1, the inner tube 3 and the clamping assembly 5 are all made of ABS plastic material.
[0031] By adopting the above technical solution and providing the anti-slip grooves 9, the friction force on the surface of the threaded cap 504 is increased.
[0032] The working principle of the utility model is as follows: when in use, the pen body 6 is inserted into the outer tube 1 and the inner tube 3, and according to the length of the pen body 6, the inner tube 3 is made to slide on the inner wall of the outer tube 1, and then the threaded cap 504 is rotated, and under the action of the tapered thread 503 and the notch 502, the clamping head 501 is contracted to clamp the pen body 6. When holding the pen, the user puts the finger into the corresponding indicating groove 7 to help the user to correctly grasp the pen holding posture. At the same time, the indicating groove 7 and the indicating protrusion 8 can prevent the dynamic offset between the three fingers holding the pen and the pen shaft, which affects the correction process.
