The rotary fixed blade 20, the rotary movable blade 22, the movable blade support 24, the floating support 26, the motor shaft connecting block 8 and the motor 9 are all on the same straight line, when the shaver is in a working state, a convex key at the end part of the motor shaft connecting block 8 is inserted into a linkage groove at the bottom of the floating support 26, the rotation output of the motor 9 drives the floating support 26 to rotate through the motor shaft connecting block 8, the floating support 26 drives the movable blade support 24 connected with the movable blade support through a claw to rotate, and then the rotary movable blade 22 is driven to rotate. The connection between the motor shaft connecting block 8 and the floating support 26 can be disconnected by pushing the supporting rod 14 to drive the cutter head, so that the motor shaft connecting block 8 and the floating support 26 are separated from each other, and the effect that the cutter head in a non-working state loses power is achieved. The PCB 10 is connected with the switch button 3 through an electric connection structure, the switch button 3 is arranged on the surface of the head support 6, starting is realized through pressing down, and another necessary condition for the operation of the shaver is that the floating support 26 of the shaver head is connected with the motor shaft connecting block 8, so that the rotating output of the motor 9 can reach the rotating blade 22 of the shaver head to drive the rotating blade 22 to rotate. The switch button 3 is made of soft materials, a tact switch of the PCB 10 is arranged below the surface of the switch button 3, and the soft materials of the switch button 3 are pressed to enable the tact switch to be started, so that the effect of conducting a working circuit of the PCB 10 is achieved.

In another embodiment, the shaver is not provided with the switch button 3, and when the shaver head reaches the working state by manual pushing, the support rod 14 drives the switch magnet assembled on the fixed block 7 to move together, so that the switch magnet reaches the induction area of the hall switch arranged in the shaver body, thereby triggering the hall switch on the PCB 10 to realize the starting operation of the shaver, and similarly, the floating support 26 of the shaver head is connected with the motor shaft connecting block 8.

In this embodiment, the convex key at the end of the motor shaft connecting block 8 is in a triangular structure, the vertex angle part adopts smooth curved surface transition, so that the connection stability between the motor shaft connecting block 8 and the floating bracket 26 is improved, and the three convex triangular structures can apply forces on the same circumference to the floating bracket 26 when rotating, thereby being beneficial to pushing the floating bracket 26 to rotate.

In this embodiment two micro motors are used, reducing the volume by reducing the power of a single drive.

In order to fill the gap in the middle of the rotary fixed blade 20, a decorative sheet 19 is arranged for installation, a platform structure is formed in the middle of the rotary fixed blade 20, the decorative sheet 19 is fixed in the center of the rotary fixed blade 20 through gluing or clamping connection, and the top height of the decorative sheet 19 is lower than the upper surface height of the rotary fixed blade 20. The decorative sheet 19 fills the gap to play a role in decoration, also shields the entrance to the interior of the cutter head to play a role in ash blocking, internal structure protection and the like.

In other embodiments, movement of the support pole 14 may be configured to operate semi-automatically or fully automatically. Miniature mobile motors are additionally arranged on two sides in the inner machine body, the operation of the mobile motors is started through the button 3, the mobile motors work to drive the supporting rods 14 to slide on the sliding grooves, and when sudden resistance caused by limitation of the steel balls 13, the bottoms of the sliding grooves and the like is received, the mobile motors stop working, or the running time of the mobile motors is limited according to the moving speed, so that the supporting rods 14 move to the required height position. The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
