Description

Technical Field

[0001] The present invention relates to the technical field of razors, and specifically to a floating and fixed structure of a razor. Background Art

[0002] An electric razor consists of a stainless steel mesh cover, an inner blade, a micro motor and a housing. The mesh cover is the fixed outer blade with many holes through which the beard can extend. The micro motor is driven by electric energy to drive the inner blade to act. Using the shearing principle, the beard extending into the holes is cut off. Electric razors can be divided into two types, rotary and reciprocating, according to the action characteristics of the inner blade. The power sources used include dry batteries, storage batteries and AC charging, etc. At present, the structural mode of most razor head seats in the market is as follows: one razor head seat with three mounting holes on it. There is a triangular reinforcing rib with a square hole in the middle of the three forks of the razor head seat. Three knife grid frames are arranged on the mounting holes, and the knife net is placed inside the knife grid frames. A support frame assembly composed of three plastic cards, a spring piece and a knob with an inverted buckle is combined to form a razor head seat. The up and down floating of the knife net is achieved by the plastic card compressing the six-claw spring piece to move up and down and is fixed or released by the knob. In the prior art, the disadvantages of this structural mode are that there are many parts, the structure is complex, the assembly working hours are long, and the cost is high.
