Description

Nail clipper

The invention relates to a nail clipper, in particular to a nail trimming scissors which can be carried around as a small box-shaped body, belonging to the field of hand nails and toenail tools.

Background technique

Most of the nail clippers on the market are opened when the collection is opened. Not only is it easy to wear clothing or handbags, but it can also scratch the user's body, which is very dangerous. In addition, the cutting edge becomes dull due to constant friction with foreign objects, and dust is also easily trapped in the gap between the cutting edges, shortening the life of the nail clipper. Since the edge of the nail clipper is opened, its thickness is increased and it has an irregular shape, which is not only inconvenient to collect, but also difficult to combine with other tools to make a multi-purpose tool, narrowing the scope of application.

In order to ensure safety, some nail clippers are provided with a box. After the user uses the nail clippers, the nail clippers are placed in the box. Although this can prevent the nail clipper from wearing the clothing or the body during storage, and can protect the cutting edge, the box body is easy to be lost, and the box body needs to be opened before the use to take out the nail clipper, and then the pressure bar of the nail clipper is adjusted to the use state. , inconvenient to use.

There are also nail clippers available on the market that can be folded into a sheet after use. The nail clipper is snapped during collection, which is safe and reliable, and protects the cutting edge. However, although the cutting edge has been bitten, the left and right ends are generally angular, failing to form a smooth surface, so there is still the danger of scratching the user's body, and there are gaps between the cutting edges to easily hide dust.
