Electric jar opener

An electric jar opener, comprising:

• a housing;
• a first clamping jaw group extending from the housing;
• a second clamping jaw group extending from the housing;
• a movement mechanism disposed inside the housing;
• wherein,
• the first clamping jaw group comprises two oppositely-disposed mutually facing first clamping jaws for clamping a jar body, and the second clamping jaw group comprises two oppositely-disposed mutually facing second clamping jaws for clamping and screwing a lid;
• the movement mechanism comprises a motor and a differential with two outputs driven by the motor, the movement mechanism is capable of driving the first clamping jaws and the second clamping jaws to move;
• a first output of the differential is in transmission connection to the first clamping jaws and a second output thereof is in transmission connection to the second clamping jaws;
• the differential comprises one or more planetary gears, a transmission shaft, a rotatable shell, an intermediate gear, a first driven gear and a second driven gear;
• an annular gear is connected to the rotatable shell, and a driving gear attached to the motor is connected to the annular gear;
• wherein the rotatable shell is driven by the motor to rotate about an axis of the transmission shaft;
• each planetary gear is disposed inside the shell, when the shell is driven by the motor each planetary gear is capable of rotating about the axis of the transmission shaft and is also capable of rotating relative to the shell, the transmission shaft rotates together with the shell;
• each planetary gear engages with the intermediate gear, the first driven gear rotates together with the intermediate gear, the second driven gear rotates together with the transmission shaft;
• the first driven gear defined as the first output end of the differential is in transmission connection to the first clamping jaws, and the second driven gear defined as the second output of the differential is in transmission connection to the second clamping jaws.
