1. Field of the Invention
The present invention relates to a driver head with a lamplight for providing an illumination and screwing other components.
2. Description of the Related Art
Referring to FIGS. 3 to 5 and U.S. Pat. No. 6,183,103, a body 22 includes a transverse passageway 44, and a switch element 42 made of an electrically conducting material and contained in a passageway 44 of the body 22 and movable to left and right sides, and the switch element 42 includes two dispositions 6068 for connecting an insulator ring 7072. However, the structure of such patented invention has the following drawback:
1. If there is a screw component on a hole, the body 22 may not be put into a smaller hole diameter and connected to a bushing to rotate the screw component.
2. Both ends of the switch element 42 are protruded and exposed from the outer circumferential surface of the body 22, such that when the body 22 is rotated, the body 22 will hit other components easily, and the switch element 42 will be collided easily and shifted to another position automatically.
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; a control member is pivotally installed in said transversal groove of said body; an electrically conducting plate is contained in said conducting groove of said control member; 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; a resilient element is installed in said third groove; 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.
Referring to
The body 10 is a general driver head made of an electrically conducting metal, and an end of the body 10 is a connecting end 11 and sequentially includes a first groove 12, a third groove 141 and a second groove 14, and the second groove 14 is disposed in the connecting end 11, and the first groove 12, third groove 141 and second groove 14 are interconnected, and the outer circumferential surface of the first groove 12 of the body 10 has a plane 101, a transversal groove 13 disposed transversally and interconnected to the first groove 12 and the plane.
The control member 20 is made of an insulating material and the control member 20 is pivotally coupled into the transversal groove 13 of the body 10, and a narrow groove shaped conducting groove 201 is disposed at a corresponding position of the first groove 12, and a plane 202 is disposed on an outer circumferential surface, and an end has a poking chunk 203 protruded and exposed from the plane 101 of the body 10 for facilitate a user to poke the poking chunk 203 by a hand, so that the control member 20 can rotate to an appropriate angle.
The electrically conducting plate 21 is disposed in the conducting groove 201 of the control member 20 and the length of the electrically conducting plate 21 is greater than the width of the first groove 12, such that two rear sides can touch the body 10 after the electrically conducting plate 21 is turned, and can be aligned with the outer circumferential surface of the control member 20 after the electrically conducting plate 21 is put in.
The light emitting element 30 is a light emitting diode (LED) or other light emitting component, and the light emitting element 30 is installed in the second groove 14 of the body 10, and the outer circumferential surface of the light emitting element 30 is in contact with the body 10.
The power supply elements 40 come with a plurality and are installed in the third groove 141, and the power supply element 40 is slightly in contact with the light emitting element 30, such that the power supply element 40 can supply an electric power. When the poking chunk 203 of the control member 20 is turned, the electrically conducting plate 21 or the control plane 202 of the conducting groove 201 can be contacted or disconnected with the power supply element 40 to form a circuit.
The resilient element 50 is an electrically conducting metal spring installed in the third groove 141, and an end of the resilient element 50 pressed on the light emitting element 30, and the other end of the resilient element 50 presses on the power supply element 40.

In another embodiment of the present invention, the body 10 has a third groove 141 with the same diameter of the second groove 14, and the power supply element 40 is contained therein in compliance with the diameter of the third groove 141.
The advantages of the present inventions are listed below:
1. The light emitting effect is adopted to facilitate users to use the driver head in a dark place, and allow users to know and recognize the driver head easily for the screw operation.
2. The control member 20 has a control plane 202, for providing a positioning effect for the structure.
3. During the operation of the driver head, the body 10 will not be hit by other object and thus shifted to other position automatically.
