For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings. Example 1

[0039] See also Figure 1-7 As shown, the present embodiment provides a swing motor for a hair clipper, comprising a housing 1 and a silicon steel lamination 2 and an insulating wire frame 3 arranged inside the housing 1;

[0040] The silicon steel lamination 2 is an "E" shaped structure;

[0041] The insulating wire frame 3 is an "I"-shaped structure, and a through hole is opened along the center line of the insulating wire frame 3 in the length direction, and the insulating wire frame 3 is sleeved on the middle end of the silicon steel laminate 2 through the through hole;

[0042] A coil 4 is wound on the insulating wire frame 3, and both ends of the coil 4 are electrically connected to a variable frequency power supply;

[0043] A left magnetic sheet 5 and a right magnetic sheet 6 are arranged above the insulating wire frame 3. The left magnetic sheet 5 and the right magnetic sheet 6 are arranged correspondingly, and the polarities of the left magnetic sheet 5 and the right magnetic sheet 6 are opposite.

[0044] There is a gap between the bottom ends of the left magnetic sheet 5 and the right magnetic sheet 6 and the silicon steel laminate 2;

[0045] Two magnetic guide plates 7 are correspondingly arranged at the tops of the left magnetic plate 5 and the right magnetic plate 6. A guide rod 8 is arranged within the interval between the two magnetic guide plates 7. Two ends of the guide rod 8 are respectively connected to two opposite side walls of the housing 1;

[0046] A swing seat 9 is arranged at the top of the two magnetic guide plates 7. A swing shaft 10 is connected to the top of the swing seat 9;

[0047] The axis line of the swing shaft 10 is perpendicular to the axis line of the guide rod 8;

[0048] A notch is formed at the top end of the housing 1. One end of the swing shaft 10 far from the swing seat 9 passes through the notch and is located outside the housing 1.

[0049] Specifically, the magnetic field generated by the coil 4 interacts with the magnetic fields of the left magnetic plate 5 and the right magnetic plate 6. By changing the output direction of the power supply, the direction of the magnetic field generated by the coil 4 is further changed, thereby realizing the reciprocating linear motion of the left magnetic plate 5 and the right magnetic plate 6. When the left magnetic plate 5 and the right magnetic plate 6 perform reciprocating linear motion, the two magnetic guide plates 7 will be driven to move. Since the guide rod 8 is arranged between the two magnetic guide plates 7, the guide rod 8 forms a guiding limit for the movement of the two magnetic guide plates 7. When the two magnetic guide plates 7 move, the swing seat 9 will be driven to move, and finally the swing shaft 10 is driven to perform reciprocating linear motion. By setting the output frequency of the power supply, the swing shaft 10 can reciprocate swing at a set frequency. When the swing shaft 10 is connected to the moving blade of the hair clipper, the moving blade works at a certain frequency.

[0050] It should be noted that the required swing amplitude and shearing force can be obtained by changing the winding parameters of the coil 4 and the magnetic properties of the left magnetic plate 5 and the right magnetic plate 6.

[0051] It should be noted that referring to Figure 7 As shown, the swing seat 9 includes a swing seat transverse member 901 and a swing seat longitudinal member 902. The swing seat longitudinal member 902 is connected to the upper end of the swing seat transverse member 901. The swing seat transverse member 901 and the swing seat longitudinal member 902 form a "丄"-shaped structure. The top of the swing seat longitudinal member 902 is connected to the swing shaft 10, and the bottom end of the swing seat transverse member 901 is connected to the magnetic guide plate 7; the bottom end of the swing shaft 10 can be inserted inside the swing seat longitudinal member 902. Embodiment 2

[0052] Referring to Figure 1-7 As shown, the difference between this embodiment and the first embodiment is that guide seats 11 are respectively penetrated and arranged on two opposite side walls of the housing 1 of this embodiment, and two ends of the guide rod 8 are respectively inserted inside the two guide seats 11.

[0053] Specifically, the guide seat 11 is a “C”-shaped structure, and the end of the guide rod 8 is passed through the center of the guide seat 11 and clamped by the guide seat 11, so as to facilitate the installation and removal of the guide rod 8.

[0054] In addition, a connecting member 13 is provided on the top of the swing seat transverse member 901, and the connecting member 13 is a "door" shaped structure; the opening of the connecting member 13 faces downward and sequentially sets the swing seat transverse member 901, the two magnetic conductive sheets 7, the left magnetic sheet 5 and the right magnetic sheet 6 into an integrated structure;

[0055] Two ends of the guide rod 8 pass through two side walls of the connecting member 13 and are connected to two opposite side walls of the housing 1 .

[0056] Specifically, springs 12 are connected to the opposite side walls of the swing seat 9, one end of the spring 12 is connected to the side wall of the swing seat 9, and the other end of the spring 12 is connected to the inner wall of the shell 1. The extension direction of the spring 12 is parallel to the axial direction of the guide rod 8.

[0057] It should be noted that the spring 12 is connected to the longitudinal member 902 of the swing seat. The spring 12 can provide an elastic force with a certain resonance frequency and has a buffering effect. It plays a key role in the swing force and swing amplitude of the swing shaft 10. Accordingly, the swing force and swing amplitude of the swing shaft 10 can be adjusted by changing the physical properties (i.e. elasticity) of the two springs 12.

[0058] Specifically, a connecting member 13 is provided on the top of the swing seat transverse member 901, and the connecting member 13 is a "door" shaped structure; the opening of the connecting member 13 faces downward and sequentially sets the swing seat transverse member 901, the two magnetic conductive sheets 7, the left magnetic sheet 5 and the right magnetic sheet 6 as an integrated structure, ensuring that the swing seat transverse member 901, the two magnetic conductive sheets 7, the left magnetic sheet 5 and the right magnetic sheet 6 can move together;

[0059] Two ends of the guide rod 8 pass through two side walls of the connecting member 13 respectively and are connected to two opposite side walls of the housing 1 . The guide rod 8 and the two side walls of the connecting member 13 are in sliding connection.

[0060] Specifically, a swing head sleeve 14 is provided at the notch opened at the top of the shell 1 . The swing head sleeve 14 is an annular structure. One end of the swing shaft 10 away from the swing seat 9 passes through the swing head sleeve 14 and is located outside the shell 1 .

[0061] It should be noted that the swing head sleeve 14 is made of wear-resistant material.

The above examples are only used to help understand the method and core ideas of the utility model. At the same time, for those skilled in the art, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
