Description

Technical Field

[0001] The invention relates to the field of writing tools, in particular to a click pen. Background Art

[0002] At present, the structure of the click pen on the market usually includes a pen case, a pen core is installed in the pen case, a clickable pen cap is connected to the upper end of the pen core, a pen head is connected to the lower end of the pen case, and a spring is arranged inside the pen head and is jacketed around the pen core. The user can extend the tip of the pen core from the pen head by pressing the pen cap, or retract the tip of the pen into the pen head by pressing the pen cap again. It is very convenient to use and is very popular among users.

[0003] Because the core of the click pen is very easy to come out, it causes trouble for users during transportation and carrying. For example, in the click pen with the above structure, if the pen cap is squeezed during transportation, the core of the click pen will come out, and the pen tip will easily rub against foreign objects (storage box), causing the storage box to become dirty. If the pen tip is against the storage box for a long time, the core may leak ink. In response to this phenomenon, some technicians have come up with a solution, which is to apply wax (wax sleeve) to the tip of the core before the click pen leaves the factory to protect the core and prevent the click pen from being rubbed everywhere or leaking ink during transportation.

[0004] However, since the wax cover applied to the pen tip is disposable, the wax cover cannot be put back on the pen tip after the user unpacks and uses the click pen. When carrying the click pen on the person, if the pen cap is accidentally pressed, the click pen may be ejected, causing the pen tip to scratch clothes. If the pen tip leaks ink, the ink will seep into clothes, causing great inconvenience for the user to wash clothes. Summary of the invention
