Abstract
The utility model provides an electrical apparatus head swing structure. A base seat of the electrical apparatus head swing structure is provided with a staddle. The staddle is provided with an action part. The staddle is capable of swinging from left side to right side on the base seat through a driving assemble which is composed of a gear, a fluted disc and a driving motor. A control circuit controls the driving motor to rotate and reverse. The control circuit receives sensing signals of two sensing elements to control the staddle to return to an original position. A timing unit in the control circuit controls rotating time and reversing time of the driving motor to control a swinging angle of the staddle. Therefore the electrical apparatus head swing structure is formed. By using the electrical apparatus head swing structure, a user can easily adjust the swinging angle of the staddle according to demands of the user, and the electrical apparatus head swing structure is convenient to use.
