Description

Multi-gesture bedside writing pen

Technical Field

The utility model relates to the technical field of stationery, in particular to a multi-gesture bedside writing pen.

Background

The pen refill is widely applied to daily life, study and office as a writing tool, and comprises a pen refill tube and a pen refill head, wherein the pen refill tube and the pen refill head are connected through threads, writing liquid is filled in the pen refill tube, steel balls are filled in the pen refill head, and when writing, the liquid in the pen refill tube slowly flows out through the steel balls at the front end of the pen refill head, so that the aim of writing is fulfilled. At present, the common pens and ball-point pens mostly finish the ink discharge of the pen point by means of the gravity of liquid drops, so that the pen and the ball-point pen cannot be used under the gravity-free or anti-gravity condition. The bedside writing pen is a pen which is suitable for obliquely writing in a bedside lying posture, and can be used in an antigravity state, and ink is cleanly and leaklessly leaked, so that the traditional pen and the ball pen are not suitable for bedside lying writing, and the pencil can be used in the antigravity condition, but the broken pencil lead possibly falls into the respiratory tract due to the fact that the pencil lead is easy to break, and potential safety hazards exist. At present, space pens for space microgravity or gravity-free conditions are invented in the aviation field at home and abroad, for example, chinese patent CN106240194A discloses a novel space pen refill, which is provided with a movable inner plug, a first lubricating grease layer and a second lubricating grease layer, elastic pressure is provided for the inner plug by a spring, writing under gravity-free, microgravity or antigravity conditions is realized, leakage of ink is avoided, and the space pen is suitable for writing at a head of a bed, but the space pen is complex in structure and process, high in cost and price, and inconvenience is brought to a user.
