Abstract: A servo includes a motor, an output shaft used to drive an external component and having an external lateral surface, a gear set arranged between the motor and the output shaft and used to transmit power from the motor to the output shaft. The gear set includes an output gear arranged around the output shaft. The output gear defines a through hole that allows the output shaft to pass therethrough. The through hole has an internal lateral surface facing the external lateral surface. The servo further includes a connection ring arranged around the output shaft between the external lateral surface and the internal lateral surface. The connection ring is used to connect the output gear to the output shaft when a load placed on the output shaft is less than a preset value, and disconnect the output gear from the output shaft when the load exceeds the preset value.
