Description

a kind of pen

technical field

The invention relates to the field of pens, in particular to a rotating pen.

Background technique

Pen spinning is a recreational activity of turning a pen with fingers using different methods and techniques. It can be composed of many different moves. Pen-twirling is sometimes classified as a training form of acrobatic sport. Students in many parts of the world love to spin their pens. Turning the pen can exercise the human cerebellum. The human cerebellum is responsible for body balance and sensory coordination. Often playing with the pen can train the hands, eyes and cerebellum. At the same time, the activity of the cerebellum will also stimulate the nerve cells of the brain. Long-term training can help improve concentration, memory and learning ability.

Ordinary writing pens generally include a pen holder, a pen core and a pen cap. During the pen turning process, due to uneven weight distribution, it is easy to lose the sense of balance, which will limit many pen turning methods. Some rotating pens in the prior art are long in size, although their structure is symmetrical, and their weight is evenly distributed on both ends of the pen. However, due to the movement of the pen during the rotation process, the position of the center of gravity of the pen cannot be accurately grasped, which also causes the continuous rotation of the pen. not long time.
