Description

[Detailed description of the invention] The present invention relates to an electric razor with a trimmer mechanism.

In this type of electric razor with a trimmer mechanism, the trimmer mechanism is rotatably protruded to perform the function of shaving the edges, and the trimmer mechanism is movable toward the net blade, so that the trimmer mechanism can cut curly and long hair. Preferably, the hair is shaved with an X-net blade while the hair is shaved.

In this case, the trimmer mechanism is usually prevented from protruding by a rotation stopper, and is configured to release the rotation stopper by pushing in a switch plate that slides the trimmer mechanism.

However, the conventional razor mechanism is provided in such a way that the rotation stopper is released by pushing in the switch plate, so it has the disadvantage that the outside of the push-in space of the switch plate is shaped like a dog. Ta.

Furthermore, when ensuring smooth pushing operation of the switch plate, a gap is created between the body and the switch plate, which impairs the appearance.
