The more you use the scissors, the tighter. What do you do?
Attention, 1, the purpose of the pad iron is to put a rivet on the head, if the iron is not thick enough to pad 2, must be empty, or the more knock more tight; 2, can not knock too heavy. Knock on it and try it on. OK, if it doesn't work, knock again.
Methods: to find a more formal hole of a middle iron (e.g., nut) requirements of the middle hole of two pieces of iron scissors connecting parts rivets slightly larger, scissors connected with the rivet iron ring on the ground (or hard place) and knock on the head rivet without trapping with a hammer, it the problem can be solved.
Relatively simple way: with one chopstick, banana, a little vegetable oil, point a few vegetable oil at the joint of the two scissors, and open and close scissors back and forth, it will become easier after a few.
