Description

Functional safety nail clipper {Functional safety nail clipper}

The present invention relates to a functional safety nail clipper that allows a user to conveniently and safely cut nails.

In general, long protruding nails are periodically cut using nail clippers for the purpose of sanitary safety, maintenance of cleanliness, and prevention of injury.

These nail clippers are typically composed of a blade for performing a cutting operation, a handle extending from the blade for the user to hold by hand, and a lever connected to the blade for cutting the blade according to the user's pressing operation.

However, since the blade of a conventional nail clipper has a straight shape with the center and both sides of the same height on a frontal basis, it does not correspond to the shape of the nail, so the nail does not fit snugly when cutting the nail, which is very inconvenient.

In addition, since the length of the handle and the lever is very short for adults to use, it is very inconvenient to hold and press the handle and the lever with the hand.

In addition, since the lever freely rotates left and right at the top of the blade, when the lever is pressed, it is unintentionally rotated to the left or right, so that the cutting operation of the blade does not occur, which is inconvenient to use.

Furthermore, since the blade and the handle are integrally formed, there is an economically inefficient problem in that when the blade is worn out and cannot be used, it must be discarded and a new one purchased.

In addition, there is a problem in that the blade is not provided with a protective means for limiting the input length of the nail, which also causes the disadvantage of cutting the nail to a length longer than necessary.

In addition, since the lever and the handle are located in the opposite direction to the hand position when cutting the nail, it is not easy to press through the lever, which is inconvenient to use.

Therefore, in order to allow users to conveniently and safely cut nails, it is urgent to develop a nail clipper having a structure capable of solving the above problems.
