Description

Pressing pen

Technical Field

The utility model relates to a writing tools field especially relates to a pressing pen.

Background

At present, the structure of the pressing pen on the market usually comprises a pen shell, a pen core is arranged in the pen shell, the upper end of the pen core is connected with a pressing pen cap, the lower end of the pen shell is connected with a pen point, a spring externally sleeved on the pen core is arranged in the pen point, a user can stretch out the pen point of the pen core from the pen point by pressing the pen cap or retract the pen point into the pen point by pressing the pen cap again, and the pressing pen structure is very convenient to use and popular with users.

The knock pen is very easy to eject, which causes troubles to users in transportation and carrying. For example, if the cap is squeezed during transportation, the pen can be pushed out, the pen point is easily wiped on foreign objects (storage box), the storage box is dirty, and if the pen point is pressed against the storage box for a long time, ink leakage of the pen core may occur. In order to solve the problem, some technicians also think of a solution, namely before the knock pen leaves a factory, the pen point of the pen core is coated with wax (a wax sleeve) to protect the pen core and prevent the knock pen from being wiped everywhere or leaking ink in the transportation process.

However, the wax sleeve coated on the pen point is disposable, so that after the user unseals the pressing pen, the wax sleeve cannot be sleeved back to the pen point, when the pressing pen is carried on the body, if the user presses the pen cap by mistake, the pressing pen can be led out of the core, and therefore the pen point dirties clothes, and if ink leakage occurs in the pen point, the ink can seep into the clothes, and great inconvenience is brought to the user for cleaning the clothes.
