Trouble in use

Mechanical pencils :Why no lead coming out

Check that the lead tank has a spare lead. Next, check the thickness of the lead. It does not come out even if I put a 0.7 mm lead to 0.5 mm sharp. Please check the lead diameter. Or, is the pipe of the tip bent or collapsed? Please be careful because the tip pipe may deform when you drop it or it is punched. If the broken lead is clogged, remove the tip cone by turning it to the left, removing the wick of the gold and chunk.
