Oscillating motor and electric clippers

An electric clipper, comprising an oscillating motor and a cutter head;

• wherein the oscillating motor comprises:
• a U-shaped magnetic yoke having a first support leg and a second support leg, and the first support leg and the second support leg are wound with coils;
• a control circuit electrically connected to the coils and generating alternating pulses to generate alternating magnetic poles at end faces of the first support leg and the second support leg of the U-shaped magnetic yoke;
• a swing arm swingable around a fulcrum;
• wherein the first support leg and the second support leg respectively extend outward from a base portion of the U-shaped magnetic yoke so as to form a U-shaped structure;
• the swing arm is substantially arranged in an extending direction of the first support leg and the second support leg;
• the swing arm is bounded by the fulcrum, an end of the swing arm close to the U-shaped magnetic yoke is an inner arm and the other end of the swing arm remote from the U-shaped magnetic yoke is an outer arm;
• the inner arm levers the outer arm to swing around the fulcrum in a swinging plane where the swing arm locates under the action of electromagnetic force;
• a second magnetic yoke mounted at one end of the inner arm close to the U-shaped magnetic yoke for forming magnetic pathways;
• wherein the second magnetic yoke and the swing arm form a T-shaped structure;
• and
• a first permanent magnet, a second permanent magnet, a third permanent magnet, and a fourth permanent magnet being fixedly mounted on the second magnetic yoke;
• wherein the first permanent magnet, the second permanent magnet, the third permanent magnet, and the fourth permanent magnet are orderly spaced and distributed on a same circumference centered on the fulcrum;
• radial end faces of the first permanent magnet and the fourth permanent magnet have a same polarity;
• radial end faces of the second permanent magnet and the third permanent magnet have a same polarity;
• the radial end faces of the first permanent magnet and the second permanent magnet have opposite polarities and are provided corresponding to an end face of the first support leg;
• the radial end faces of the third permanent magnet and the fourth permanent magnet have opposite polarities and are provided corresponding to an end face of the second support leg;
• end faces of the first permanent magnet and the second permanent magnet correspondingly have an air gap with the end face of the first leg;
• end faces of the third permanent magnet and the fourth permanent magnet correspondingly have an air gap with the end face of the second leg;
• wherein the cutter head is connected to the outer arm of the swing arm;
• the force output portion is provided at the outer arm;
• the force output portion has an arc-shaped outer wall;
• a toggle connecting body is provided at the cutter head;
• a groove matching the force output portion is provided at the toggle connecting body;
• and the force output portion is mounted within the groove.
