Description
Technical Field
[0001] The utility model relates to the technical field related to signing pens, in particular to a signing pen with a pen head and eraser conversion. Background Art
[0002] A signature pen refers to a pen specially used for signing or signing samples. There are water-based signature pens and oil-based signature pens. In the past, fountain pens were used, but they were gradually replaced by gel pens, so these pens are collectively referred to as: signature pens. Water-based signature pens are generally used on paper, and if used on a whiteboard or sample, they are easily wiped off; oil-based signature pens are generally used for signing samples or other permanent marks. Oil-based signature pens are difficult to wipe off, but can be cleaned with alcohol and other substances. When we use pencils to write, we often make typos or copy the wrong content. If you want to modify the content of an ordinary pencil, you need to be equipped with an eraser or install an eraser on the end of the pen to make corrections. However, you have to take out the eraser or turn the pen head every time you make corrections, or the eraser is used up, etc. These will make it inconvenient for us to modify the content. Therefore, we especially need a signature pen with a pen tip and eraser conversion.
[0003] Because most of the existing eraser-convertible signing pens do not have the conversion function, it is necessary to combine the refill and eraser at the pen compartment and add a pressure button at the pen barrel, so that the button can be used to adjust the refill at the pen tip to switch to an eraser, reducing the need to hold the pen at the back end to use the eraser or look for the eraser to make corrections, thereby improving efficiency. At the same time, the size of the eraser is also larger than the eraser at the end of the traditional pen barrel, which can extend the service life. Utility Model Content
