Pen

Abstract

The invention provides a pen. A light emitting diode (LED) is arranged on a pothook of the pen, the LED is communicated with a battery case which is arranged above the pothook and is provided with a screw cap, the pothook is connected on a pen cap through a shaft pin, and the shaft pin enables the pothook to be stretched and retracted and serves as a power source switch controlling the power on and power off of a power supply. When the pen is used, the light emission and power on and off of the LED can be achieved through the stretching-out and retraction of the pothook. Therefore, when the pen is used at night, the LED can be directly used for lighting, and the pen is particularly suitable for being used outdoors and in the field operation.

Description

technical field [0001] The invention relates to a pen, specifically a pen equipped with a light emitting diode. Background technique [0002] All kinds of pens are used in work and study. Ordinary pens can only be used for writing, but they cannot be used normally when there is no light at night. and unable to use a pen. Contents of the invention [0003] The present invention is to provide a pen, which can directly use the light on the pen to illuminate and write, and is very convenient. [0004] The present invention includes a pen hook, and the adopted technical scheme is that: the pen is equipped with a light-emitting diode on the hook, and the light-emitting diode communicates with a battery box with a screw cap above the hook. [0005] Described hook adopts pivot pin to be connected on the pen cap, and pivot pin is double as the power switch that hook stretches out and draws in and can carry out power supply on-off. [0006] The beneficial effect of the present in...
