notice: There is a steel ball inside. First, apply grease in the hole, then put the steel ball in. The grease sticks the steel ball to the hole, and then install the spring. Otherwise, the steel ball will fall off, resulting in the steel ball not being installed in the exact center of the spring, and the spring will be damaged and deformed.
