Abstract

The invention discloses a pen for preventing short sight and correcting postures. A sleeve is arranged at the front section of a penholder, a spring cavity is arranged between the penholder and the sleeve and internally provided with a compression spring, one end of the spring pushes the penholder, and the other end of the spring pushes the sleeve; finger holding points are arranged on the holding part of the sleeve and have elasticity; and a non-slip structure is arranged on the inner surface of each holding point of the sleeve, and a non-slip structure is also arranged at the corresponding position outside the front section of the penholder. The two non-slip structures are not articulated if people hold the pen incorrectly, and people cannot write because the sleeve slips downwards due to stress to cover a pen point. When the pen is correctly held, fingers press the holding points, the two non-slip structures are articulated and the condition of correct pen-holding is satisfied to ensure that the sleeve and the penholder do not slip and people can write normally. The structure is suitable for various rigid pen products.
