The stapler won't press down. What happened?

It may be that the nail outlet is too wide, or the blade of the nail pressing blade is uneven. After separating the stapler from the top and bottom, try knocking down the blade.

Stapler:

Stapler (d not ng sh ū j:), each office has at least one stapler, which provides us with an ideal means to bind many pages together and save them. I believe many students also have staplers at home. In fact, the earliest stapler was not an office product at all, it was developed for the printing industry.
