Electric Stapler and Control Method Therefor

An electric stapler, comprising:

• an operating handle;
• a shaft assembly, extending from the operating handle;
• a cutting knife assembly, provided at one end, away from the operating handle, of the shaft assembly and comprising a knife pushing member;
• a motor, provided in the operating handle and configured to drive the knife pushing member to move;
• a trigger, comprising:
• a firing unit for a user to trigger, the firing unit being configured to send a firing signal representing a knife feeding action and a firing stopping signal representing stopping of the knife feeding action;
• and a knife returning unit for the user to trigger, the knife returning unit being configured to send a knife returning signal representing a knife returning action and a knife returning stopping signal representing stopping of the knife returning action;
• and
• a control module, electrically connected to the motor and the trigger, where the control module controls, when detecting the firing signal, the motor to drive the knife pushing member to perform the knife feeding action towards a final firing position, and the control module controls, when detecting the firing stopping signal, the knife pushing member to stop the knife feeding action;
• and
• the knife pushing member has, during the knife feeding action, a first state of stopping between an initial position and the final firing position, when in the first state, the control module controls, when detecting the knife returning signal, the knife pushing member to perform the knife returning action towards the initial position, and during the knife returning action, the control module controls, when detecting the knife returning stopping signal, the knife pushing member to stop the knife returning action.
