Abstract

The invention discloses a handwriting pen with automatic nib protecting function. The rear end of a pen core is provided with a connecting head, and the connecting head is provided with a plurality of steps; a plurality of groups of support devices are uniformly distributed on the circumference on the inner wall of a penholder at the rear end of the connecting head, the support device comprises asupport step fixed on the penholder and a support rod capable of being rotationally connected on the support step on front and back, and the rear part of the support rod is provided with a support rod offsetting spring which is connected with the cavity wall of the penholder; and the rear part of the support rod is provided with a counterweight ball chamber, and a first counterweight ball and a second counterweight ball are arranged in the counterweight ball chamber backwards in turn. The pen is upright when writing so that the nib is extended out and pressed tightly for writing; and after the writing is finished, the penholder is placed horizontally, and the nib can be automatically retracted to the interior of the penholder. Automatic retraction of the nib can be realized without pressing a button or other operations, so the handwriting pen is very convenient to use and labor-saving, and the nib can be well protected.

Description

[0001] technical field [0002] The invention relates to a stylus, in particular to a stylus with a pen point automatic protection function. [0003] Background technique [0004] [0005] A pen is a tool used by people for writing, and the nib is the most important and also the most fragile part of a pen. Once the nib is damaged, the pen cannot be used. General pens all need to be provided with a pen cover to protect the nib. However, it is cumbersome to take and place the pen cover and is easy to lose. Therefore, there is another kind of reliable spring that retracts the pen holder so that the nib is retracted into the pen holder for protection. Generally, it is mostly a ballpoint pen or a signature pen. But when this pen is in use, when the nib needs to be extended or retracted, a button at the end of the pen holder needs to be pressed, which still has the disadvantage of being inconvenient to use. Simultaneously when forgetting to press the button to retract the nib...
