Referring to FIGS. 1 and 2, a driver head comprises: a body 10, a control member 20, a light emitting element 30, a power supply element 40 and a resilient element 50.
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 FIGS. 1 and 2, the light emitting element 30 is installed in the second groove 14 of the body 10 and then installed in the resilient element 50, and the power supply element 40 is installed in the third groove 141, and the conducting groove 201 of the control member 20 is installed in the electrically conducting plate 21, and then the control member 20 is contained in the transversal groove 13, and the plane 202 of the control member 20 presses at an end of the power supply element 40 and the light emitting element 30, and the resilient element 50 and the power supply element 40 will be aligned linearly, and the poking chunk 203 is protruded and exposed from the plane 101 of the body 10. After the assembling is completed, plane 101, the semi-sectional view of the driver head is shown in both FIGS. 3 and 4.
In FIGS. 5 and 6, when the poking chunk 203 of the control member 20 faces towards the plane 101, the control member 20 in the transversal groove 13 controls the plane 202 to press the power supply element 40, such that the control member 20 controls the plane 202 to be electrically disconnected, and the power supply element 40 cannot be in contact with the body 10, and the light emitting element 30 cannot have a light emitting effect.
In FIGS. 7 and 8, when the poking chunk 203 is turned, such that the control member 20 is rotated to an angle, and the poking chunk 203 faces the bottom of the plane 101, and the electrically conducting plate 21 of the control member 20 in the transversal groove 13 presses an end of the power supply element 40, such that the electrically conducting plate 21 and the body 10 are in contact with each other through an electrically conducting material, and the circuit allows the light emitting element 30 to have a light emitting effect.
In FIG. 9, the electrically conducting plate 21 includes a protruding chunk 211 protruded from the electrically conducting plate 21, and the control member 20 includes a conducting groove 201, and the electrically conducting plate 21 is contained in the conducting groove 201, and the protruding chunk 211 is protruded from the outer circumferential surface of the control member 20, and the control member 20 installs a poking chunk 203 protruded from the plane 101 of the body 10, and the control member 20 is installed in the transversal groove 13 of the body 10. If the control member 20 is rotated, the outer circumferential surface of the protruding chunk 211 of the control member 20 or the control member 20 itself is in contact with an end of the power supply element 40 to control an electric connection and determine whether or not the light emitting element 30 emits light. In FIGS. 10 and 11, if the poking chunk 203 of the control member 20 faces the top of the plane 101, the outer circumferential surface of the control member 20 will be in contact with an end of the power supply element 40, and thus will not be electrically conducted, and the light emitting element 30 will not emit light.
In FIGS. 12 and 13, if the poking chunk 203 faces the bottom of the plane 101, the poking chunk 203 will drive the control member 20 to rotate to an angle. After the protruding chunk 211 of the electrically conducting plate 21 is rotated to press an end of the power supply element 40, an electric connection is produced to allow the light emitting element 30 to emit light.
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.
