Patent ID: 7434952

Claim:
A driver head, comprising: a body, a control member, a light emitting element and a power supply element, wherein an end of said body is a connecting end, and said body sequentially includes a first groove, a third groove and a second groove, and said second groove is disposed in said connecting end, and said first groove, said third groove and said second groove are interconnected, and said first groove of said body has a plane at an outer circumferential surface, and the transversal position of said body includes a transversal groove interconnected with said first groove and said plane; a control member is pivotally installed in said transversal groove of said body and has a conducting groove corresponding to said first groove and a poking chunk disposed at an end and protruded from said plane of said body plane; an electrically conducting plate is contained in said conducting groove of said control member, and the length of said electrically conducting plate is greater than the width of said first groove, and structurally said control member includes an electrically conducting plate and a control plane; the outer circumferential surface of a light emitting element is in contact with said body; a plurality of power supply elements are installed in said third groove and slightly in contact with said light emitting element, such that said power supply element supplies an electric power and said light emitting element has a light emitting effect, and if said control member poking chunk is turned, said electrically conducting plate or said control plane in said conducting groove will be connect or disconnect said power supply element to form a circuit; a resilient element is installed in said third groove, and an end of said resilient element presses on said light emitting element and another end of said resilient element presses on said power supply element; said control member has a conducting groove, such that said electrically conducting plate can be installed in said conducting groove, and said control member can be turned to drive said electrically conducting plate or said control plane to contact said power supply element, for controlling an electric connection.
