ABSTRACT:
The structure of the shears with a tongs is that a shears overlaps a tongs. There are rivets at the end of the two handles of the two objects. The center hole of the shears cooperates with the round hole of the pivot. The hole of the overlapped parts of the tongs plates is elongated. That makes the tongs plates have more elastic space and move forward and backward in a slanting direction. The noses of the tongs propped by a tension spring can open outwards. When opening, the tongs using the ends of the handles as the axle center makes the shears open as well. Then, the noses of the tongs is a little smaller than that of the shears. When the handles of the shears are forced to clip inwards, the tongs also clips inwards. But when the noses clip the work piece, the noses stop and the edges of the shears keep cutting inwards. The tongs clips the work piece by the force of the tension spring. That the work piece does not fall down when being cut is its feature.
