[0035] Before using the hair clipper driving structure of this embodiment, the driving structure is installed on the hair clipper, and the cutter head is installed on the other end of the swinging member 1. When in use, the driving device 6 starts to drive the driving shaft 61 to drive the driving sleeve 5 to rotate, and the rotation of the driving sleeve 5 drives the eccentric shaft 51 to rotate synchronously, and the rotation of the eccentric shaft 51 drives the swing wheel 52 to rotate in the cam driving groove 11, and transmits power to the cam driving groove 11, so that the swinging member 1 can swing left and right, and can drive the cutter head to reciprocate according to a preset trajectory; while the swinging member 1 swings, the first mounting plate 2 swings synchronously, and drives one end of the elastic steel sheet 3 to swing relative to the other end; during the swinging process, the elastic steel sheet 3 will generate a rebound force due to its own inertia, and this force is transmitted to the first mounting plate 2 and then to the swinging member 1, and the swinging member 1 can swing with the help of the rebound force generated when the elastic steel sheet 3 swings. The hair clipper driving structure of the present embodiment abandons the design of multiple driving components of the traditional driving structure and adopts a streamlined driving component layout, so that the overall structure is simpler; and the swinging member 1, the first mounting plate 2 and the second mounting plate 4 can all be formed by one-time injection molding, which simplifies the production process and improves production efficiency; in addition, the swinging member 1 can swing with the help of the rebound force generated by the elastic steel sheet 3 when it swings, reducing the motor load, thereby improving the battery life and reducing the loss of the driving device 6, thereby improving the service life of the hair clipper.

[0036] The thickness of the elastic steel sheet 3 is at least 0.06 mm; at least 10 elastic steel sheets 3 are respectively installed on both sides of the first mounting plate 2 and the second mounting plate 4; after testing by the inventor, when at least 10 elastic steel sheets 3 are installed and the thickness is at least 0.06 mm, the service life can reach more than 200 hours, which can meet the general requirements of the service life of the hair clipper.

[0037] In addition, it can also be designed that the thickness of the elastic steel sheet 3 is at least 0.09 mm, and at least three elastic steel sheets 3 are respectively installed on both sides of the first mounting plate 2 and the second mounting plate 4. The inventor has tested that when at least three elastic steel sheets 3 are installed and the thickness is at least 0.09 mm, the service life can reach more than 200 hours, thereby meeting the general requirements for the service life of the hair clipper.

[0038] One end of the elastic steel sheet 3 is fixedly mounted on the first mounting plate 2 through a first mounting structure; the first mounting structure includes a first connecting plate 21, a first riveting column 32 and a first connecting through hole 31; wherein, there are two first connecting plates 21, which are integrally formed on both sides of the first mounting plate 2; there are at least two first riveting columns 32, which are respectively formed on the outer side walls of the two first connecting plates 21; the first connecting through hole 31 is opened on one end of the elastic steel sheet 3 opposite to the first riveting column 32; the first riveting column 32 is fixedly connected to the first connecting through hole 31 by riveting, so that one end of the elastic steel sheet 3 is fixedly mounted on the first mounting plate 2; The other end of the elastic steel sheet 3 is fixedly mounted on the second mounting plate 4 through a second mounting structure; the second mounting structure includes a second connecting plate 41, a second riveting column 34 and a second connecting through hole 33; wherein, there are two second connecting plates 41, which are integrally formed on both sides of the second mounting plate 4; there are at least two second riveting columns 34, which are formed on the outer side walls of the two second connecting plates 41; the second connecting through hole 33 is opened on the other end of the elastic steel sheet 3 opposite to the second riveting column 34; the second riveting column 34 is fixedly connected to the second connecting through hole 33 by riveting, so that the other end of the elastic steel sheet 3 is fixedly mounted on the second mounting plate 4. The specific riveting fixing method is that the riveting column is made of plastic material, and the riveting column is passed through the connecting through hole during assembly, and then the free end of the riveting column extending out of the connecting through hole is subjected to hot pressing by hot pressing equipment, and the high temperature causes the riveting column made of plastic material to be softened by heat and evenly flattened under pressure, and finally the elastic steel sheet 3 is fixedly mounted.

[0039] Two first internally threaded blind holes 12 are provided at the bottom of the swinging member 1, and two first mounting through holes 23 are provided on the first mounting plate 2 opposite to the first internally threaded blind holes 12.

[0044] When in use, the driving device 6 is activated to drive the movable blade 9 to swing left and right relative to the stationary blade 91, thereby realizing the haircutting function. The hair clipper of this embodiment can reduce the motor load, improve the battery life, reduce the loss of the driving device 6, and thus improve the service life of the hair clipper.
