ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention pertains to a nail clipper.
A nail clipper commonly available in the marketplace (as illustrated in
FIG. 5
) usually comprises two steel spring pieces
1
,
3
, which have cutting edges, and a steel piece
2
, which serves as a lever. The ends of the two steel spring pieces
1
,
3
, which are located away from the cutting edges
4
,
5
, are connected together securely. The cutting edges
4
,
5
are kept away from each other in a certain distance. A hole is opened on each of the two steel spring pieces
1
,
3
near the cutting edges
4
,
5
. A nail
6
is driven into the holes. The nail
6
has a hollow at its end. The front end of the steel piece
2
bends upward and has a hole on it, thus making the front end of the steel piece
2
forming a crossrail. The said crossrail is rotary wedged in the hollow at the end of the nail
6
which passes through the two steel spring pieces
1
,
3
. While in use, the steel piece
2
is rotated and the bending part of the steel piece
2
leans against the steel spring piece
3
. By pressing the end of the steel piece
2
which functions as a lever, the cutting edges
4
,
5
of the two steel spring pieces
1
,
