The support rim 3420 and the receiving arm 3460 are positioned opposite each other, with a gap between them. The motor, transmission unit, and tool unit are conventional structures and are not shown in the figure. The motor is preferably a DC motor, and the transmission unit is preferably a planetary gear set. The tool unit is preferably a rotating cutter head shielded by a blade net. The core module 3000 also includes a rechargeable battery to power the motor. The receiving arms 3460 are a pair of arms, and each arm has a U-shaped groove. A cutter unit is disposed inside the flange portion 3440.

It includes a head 5200 at one end, fixed by the U-shaped groove of the receiving arm 3460; a tail 5400 at the other end, which can be placed on the support edge 3420; and a toothed portion 5600 located between the head 5200 and the tail 5400. The tail 5400 can pass through the gap between the support edge 3420 and the stop hook 3480. The top of the tail 5400 is higher than the top of the toothed portion 5600, and the stop hook 3480 is above the top of the tail 5400. The bracket 6000 is generally U-shaped and comprises a bracket base positioned within the bracket fixing block, a pair of bracket arms 6200 extending upward from the bracket base and arranged in opposing relation, an arm hole 6220 located on each bracket arm 6200 and distal from the bracket base, a bracket gap 6400 located between the bracket arms 6200 to allow the transmission unit 5000 to pass through, a wheel axle 6600 passing through the arm holes 6220 and the wheel hole 4020, and a protrusion 6800 located on the bracket base and capable of contacting the bottom of the transmission unit 5000. The direction of movement of the elastic member is perpendicular to the direction of movement of the transmission unit 5000. To achieve the objectives of the present invention, in this embodiment, the elastic member is replaced with an elastically deformable member, one end of which is connected to the stop hook 3480 and the other end to the tail 5400. The elastically deformable member is preferably a rubber band or tension spring to enhance the resilience of the transmission unit 5000.

[0030] refer to Figure 3-6 As shown, initially, the tail portion 5400 is located between the support edge 3420 and the limiting hook 3480, and the flange portion 3440 is located in the receiving cavity of the outer shell and is not exposed to the outside, thereby achieving a stored state. During operation, the user's finger touches the contact portion 4200 and rotates counterclockwise, and the meshing teeth 4400 drives the toothed portion 5600 to move linearly until the tail portion 5400 contacts the second limiting column 2060. At this time, the user's finger needs to apply downward pressure on the contact portion 4200, as shown in FIG. Figure 4As shown, the tail portion 5400 then passes through the second limiting post 2060 and then the first limiting post 2040, exposing the cutter unit of the flange portion 3440. At this time, the tail portion 5400 abuts against the first limiting post 2040, preventing the core module 3000 from retreating, and shaving can begin, making it more convenient for the user. To store the shaving ...

[0031] The advantages of the utility model are: increased playability and a sense of technology, facilitating miniaturization, and a retractable structure for easy storage and carrying.
