Detailed Description

The following description will be made in conjunction with the accompanying drawings.

As a specific embodiment, the multi-head razor of the embodiment of the present invention includes a main body 1 and a blade carrier assembly 3.

The main machine 1 is provided with at least three transmission members 21, and the transmission members 21 can output rotary power.

The cutter frame component 3 comprises a bearing component 4 and a shaving component 5 provided with a movable cutter 51; the transmission members 21 and the movable knife 51 are correspondingly connected, that is, the first transmission member 21 is connected with the first movable knife 51, the second transmission member 21 is connected with the second movable knife 51, and so on. The driving member 21 drives the movable blade 51 to rotate, and the cutting edge 519 of the movable blade 51 cuts off hairs such as beard of a human body, thereby shaving.

The cross section of the tool rest component 3 is in a shape formed by intersecting at least three circles; the magnetic suction pieces 6 are fixedly arranged at the sunken parts (not marked in the attached drawing) of the section of the tool rest component 3; host computer 1 is provided with magnetism correspondingly and inhales piece 6, and the piece 6 is inhaled with magnetism of host computer 1 to magnetism of knife rest assembly 3 for knife rest assembly 3 and host computer 1 releasable connection. The magnetic material 6 is a magnet, iron, or the like, and includes a device that is magnetic or can be attracted by magnetic force. Of course, it should be easily understood by those skilled in the art that at least one of the magnetic attraction piece 6 of the tool rest assembly 3 and the magnetic attraction piece 6 of the main body 1 has magnetism, so that the magnetic attraction piece 6 of the tool rest assembly 3 and the magnetic attraction piece 6 of the main body 1 can be attracted.

The cross section of the tool rest component 3 is a shape formed by intersecting at least three mutually rotationally symmetrical circles. When the tool rest component 3 is arranged on the main machine 1, the rotating angle does not need to be distinguished, and the operation is more convenient.
