I have 30 sheets 157 grams of coated paper in plastic, which is easy to fall off after loading, so I hit a straight nail, but the nail can't get in. What should I do if I keep falling when I hit

Straight nails are actually not good and easy to scratch people. Preferably a nail like a stapler. There are heavy staplers. If it's too thick, you can't get in. You can only make a hole with a fine drill, then nail it and smash it. It all depends on your binding quantity and the quality required by customers. You should operate according to the actual situation.
