The two structures of the tool bit (1) swing, the movable tool (12) and the cutter mesh (13) float are arranged, so that a user can not feel too hard in the shaving process, and the shaving comfort level is increased.

In addition, the utility model discloses a tool bit of razor can be for 1 to 5 arbitrary numbers. When the number of the cutting heads is 2, 3, 4 or 5, a person skilled in the art can easily modify the above embodiments to realize the desired cutting effect. Referring to fig. 9 and 10, when the number of the tool bits (1) is 3, the number of the second fixing thin walls (23), the second elastic members (22) and the transmission mechanisms (21) is respectively and correspondingly increased, then a rotary gear is fixedly sleeved on the first rod body (211) of each transmission mechanism (21), and linkage is sequentially formed between each rotary gear, and the rotary gears are placed on the lower end face of the connecting portion (2). At the moment, the lower end part of the first rod body (211) of the middle transmission mechanism (21) is connected with a connecting rod (311) on the motor, so that the function that the motor (31) drives the three movable blades (12) to rotate simultaneously can be realized.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
