[0011] The connecting part is located on the center line of the crossbeam.

[0012] The fixed beam is detachably connected to the handle housing.

[0013] The inner wall of the handle housing is provided with several locking platforms, and the fixed beam is provided with slots that engage with the locking platforms.

[0014] Both the bottom of the cutter head housing and the bracket are provided with fixing seats for positioning one end of the spring.

[0015] The crossbeam is made of plastic.

[0016] The beneficial effects of the present invention are: the present invention provides a hair cutting device, wherein the blade housing is mounted on a crossbeam inside the handle housing, the crossbeam can deform to meet the floating requirements of the blade housing, the structure is simple and the performance is better.

[0024] The invention will be further described below with reference to the accompanying drawings: As shown in the figures, the hair cutting device includes a blade housing 1 and a handle housing 2. The blade housing is equipped with a power source 11 and a blade assembly 3 driven by the power source for cutting hair. The handle housing includes an open end 21, and a fixed beam 4 is provided inside the handle housing. The fixed beam is equipped with a crossbeam 41 that can deform under force and return to its original position after pressure is released. A connecting part 42 is provided on the crossbeam 41. One end of the blade housing extends into the open end and connects to the connecting part. The connecting part is used to rise, fall, or swing as the crossbeam is subjected to different forces. How the blade assembly achieves shaving is existing technology and will not be described in detail. It is worth noting that the blade housing includes a motor housing 101, and the motor is installed inside the motor housing. The fixed beam and the crossbeam are connected and can be integrally manufactured. The crossbeam can be made of rubber, plastic, or metal, and it has a certain deformation capacity under force. When the blade housing is subjected to force, the crossbeam can deform, making the blade assembly easier to fit the face and providing a better shaving effect.

[0025] In this embodiment, as shown in the figure, elastic members 43 are also provided on both sides of the connecting portion. One end of the elastic member presses against the bottom of the cutter head housing, and the other end presses against the fixed beam. This provides a certain floating support effect, giving the cutter head housing a better ability to conform to the face.

[0026] In this embodiment, as shown in the figure, the connecting part is a support plate provided on the crossbeam. The support plate is provided with a connecting groove 421, and the cutter head housing is provided with a protrusion 13 that engages with the connecting groove. The connection groove and the protrusion facilitate installation.

[0027] In this embodiment, as shown in the figure, there are two crossbeams, which are arranged correspondingly front and rear and each has a connecting part. This makes the installation more stable.

[0028] In this embodiment, as shown in the figure, the connecting part is located on the center line of the crossbeam. This ensures that the forces at both ends are more balanced during deformation, resulting in better performance.

[0029] In this embodiment, as shown in the figure, the fixing beam is detachably connected to the handle housing. The fixing beam can be removed as a whole, so that the fixing beam can be connected to the cutter head housing first and then installed into the handle housing as a whole.

[0030] In this embodiment, as shown in the figure, the connecting groove includes a first connecting groove 4211 and a second connecting groove 4212. The first connecting groove is a circular groove, and the second connecting groove is a square groove. This facilitates insertion and prevents easy detachment.

[0031] In this embodiment, as shown in the figure, the inner wall of the handle housing is provided with several locking platforms 22, and the fixed beam is provided with slots 44 that engage with the locking platforms. Installation is relatively convenient. It should be noted that the slots are located on the fixed beam and will not affect the deformation of the beam.

[0032] In this embodiment, as shown in the figure, the elastic element is a spring, and both the bottom of the cutter head housing and the bracket are provided with fixing seats 5 for positioning one end of the spring to prevent the spring from dislodging.

[0033] In this embodiment, as shown in the figure, the crossbeam is made of plastic.
