The pressing plate has first and second holes of a predetermined size formed on both side surfaces thereof and a slot formed on one side surface thereof. A lever shaft is inserted into the first and second holes. A lever plate is fixed to an end of the lever shaft and has a third hole formed on a side surface thereof and a fourth hole formed below the third hole. A first spring is wound around the lever shaft and has one end inserted into the third hole and the other end inserted into the slot of the pressing plate. A second spring has one end inserted into the fourth hole and the other end connected to a side surface of the body frame for returning the lever shaft to an original position.
