Dropping-resisting pen with pen point capable of automatically retracting

Abstract

The invention discloses a dropping-resisting pen with a pen point capable of automatically retracting. The pen is composed of a pen rod, a cartridge, a spring, a positioning ring, a rotating switch, asliding block and a clamping base; a gap is formed in the side wall of the pen rod, the rotating switch is provided with a fixed shaft, a gear and a rotating handle, the cartridge penetrates a longitudinal through hole in the sliding block, the sliding block is limited by a chuck of the cartridge, a rack is arranged at one side of the sliding block, the rack is engaged with the gear, the other side end of the sliding block is guided and limited by the clamping base, during use, the rotating handle is held by the hand to be rotated towards the tail end of the pen rod, the rotating handle drives the gear to rotate around the fixed shaft, the sliding block is driven to move downwards, the chuck of the cartridge is pushed to move downwards, the cartridge is driven to move downwards, the pen point is exposed out of a pen point extending hole, and normal writing is carried out; when the pen is not used or drops down accidently, a compressed spring pushes the chuck of the cartridge to move upwards, the cartridge is driven to move upwards, the cartridge and the pen point retract, the pen point retract into the pen rod, the aim of preventing the pen point from being broken is achieved, andthe pen is convenient to use, economic, practical and high in reliability.

Description

technical field [0001] The invention relates to a writing pen, in particular to an anti-falling pen with a pen point retracting automatically. Background technique [0002] Now people mostly use ball-point pens for writing, ball-point pens include oil-based ball-point pens, neutral ball-point pens (that is, gel pens, and some are also called signature pens), water-based ball-point pens (water-based pens), medium-oil ball-point pens (medium-oil pens), erasable ball-point pens, etc. The advantage of these pens is that they are easy to use, easier to carry than fountain pens, and stronger and more durable than pencils. It is a writing stationery that people often carry. However, during the use of the pen (such as the use of an oil pen or a carbon pen), the situation of dropping often occurs, and the nib is easy to break, resulting in waste. In order to prevent the nib from being broken, several anti-fall pens have been developed. Some of these drop-resistant pens have comple...
