Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 7, it is a preferred embodiment of the present invention.

The pen capable of emitting light in the embodiment comprises an upper pen holder 1, a lower pen holder 2 which is sleeved at one end of the upper pen holder 1 and can rotate relative to the upper pen holder 1, a pen core 3 arranged in the lower pen holder 2, a light-emitting component 4 arranged in the upper pen holder 1 and a light-transmitting ornament 7 arranged at the rear end of the upper pen holder 1.

An ejector rod 5 sleeved at the upper end of the refill 3 is arranged in the upper penholder 1, an inclined groove 11 which can move up and down when the lower penholder 2 rotates back and forth relative to the upper penholder 1 and drives the ejector rod 5 to rotate back and forth is formed in the inner wall of the upper penholder 1, and the spring switch 44 is determined to be opened or closed when the ejector rod 5 moves up and down.

The outer wall of the mandril 5 is provided with a convex rib 51 which is matched with the inclined groove 11 to realize the reciprocating rotation of the mandril 5 and can move up and down at the same time. The outer wall of the push rod 5 extends outwards to form a flange 52, and a clamping groove 52a is arranged on the flange 52.
