How can I rest if I can't press the pencil?

1 First, you need to see if the pen tube is blocked. You can tap it by hand, or you can take a piece of lead from the bottom of the pen tip to the top.

2. Secondly, unscrew the nib and put it down, and push the screw back.

3. Finally, screw on the nib to solve the problem that the stylus can't be pressed out.
