Description

Self-adaptive pen holder device for correcting pen holding posture Technical Field The invention relates to the technical field of pen holder devices, in particular to a self-adaptive pen holder device for correcting pen holding posture. Background The pen holder device for correcting pen holding posture is an auxiliary tool specially designed for incorrect pen holding habit (such as fist holding, thumb, index finger, improper finger distance and the like), and helps users (especially children, beginners or hand functional rehabilitation people) to develop scientific pen holding posture through physical constraint, tactile feedback or guidance so as to solve the problems of writing fatigue, handwriting skew and the like caused by incorrect posture. The existing self-adaptive pen holder device for correcting the pen holding posture has the technical problems that 1, the clamping is unstable, the existing self-adaptive pen holder device for correcting the pen holding posture is complex in design of the clamping structure of the pen holder, and the clamping is easy to slip, misplacement and the like, so that the pen holder is unstable in use. 2. The correction effect is poor, the existing part self-adaptive pen holder cannot effectively adjust the placement position and the kneading force of fingers of a user on the pen holder, cannot effectively correct the pen holding posture of the user, and is easy to cause the solidification risk of the pen holding posture. Disclosure of Invention In view of the above-mentioned drawbacks of the prior art, the present invention is to provide an adaptive pen holder device for correcting a pen holding posture, which solves the problems of unstable clamping and poor correction effect of the adaptive pen holder device for correcting a pen holding posture in the prior art.
