Combination of power supply and detachable electric implement

1. A combination of a power supply and a detachable electric implement,

a housing, said housing defining a receiving chamber, and including a body shell and a circular cover shell, wherein the body shell has an elliptical body portion and a circular head portion dimensioned correspondingly to and for mounting the circular cover shell so as to close the receiving chamber, and wherein the circular head portion has a greater sectional dimension than that of the elliptical body portion;

a power pack mounted in said receiving chamber inside said housing, said power pack having power terminal means exposed outside said housing;

an electric implement, said electric implement having power terminal means connectable to the power terminal means of said power pack to obtain the necessary working electric power from said power pack; and

an open and replaceable coupling pair including a first coupling means implemented on said housing and a second coupling means implemented on said electric implement and detachably coupled to the first coupling means for fastening to said first coupling means to secure said electric implement to said housing and for keeping the power terminal means of said electric implement in contact with the power terminal means of said power pack.

2. The combination of a power supply and a detachable electric implement as claimed in claim 1 , wherein said power pack is a battery case.

3. The combination of a power supply and a detachable electric implement as claimed in claim 1 , further comprising a handle having two pivot pins bilaterally disposed at one end and respectively pivoted to a respective pivot hole on the circular cover shell of said housing when said electric implement is an electric sealing apparatus.

4. The combination of a power supply and a detachable electric implement as claimed in claim 3 , wherein said first coupling means is comprised of at least one hook formed at an external front side of the elliptical body portion of the body shell, and said second coupling means is comprised of at least one hook hole adapted to receive the at least one hook of said first coupling means when said electric implement is the electric sealing apparatus.

5. The combination of a power supply and a detachable electric implement as claimed in claim 1 , wherein said electric implement is a cellular telephone, said cellular telephone having an adapter, said adapter having a part forming said second coupling means.

6. The combination of a power supply and a detachable electric implement as claimed in claim 5 , wherein, when said electric implement is the cellular telephone, said first coupling means is a dovetail tongue, and said second coupling means is a dovetail groove adapted to receive said dovetail tongue.

7. The combination of a power supply and a detachable electric implement as claimed in claim 1 , wherein said power pack is a transformer connected to an external power source.

8. The combination of a power supply and a detachable electric implement as claimed in claim 7 , wherein said external power source is an AC power supply.

9. The combination of a power supply and a detachable electric implement as claimed in claim 1 , wherein, when said electric implement is an electric fan, said first coupling means is a dovetail tongue, and said second coupling means is a dovetail groove adapted to receive said dovetail tongue.

10. The combination of a power supply and a detachable electric implement as claimed in claim 1 , wherein, when said electric implement is a flash light, said first coupling means is a coupling hole, and said second coupling means is a coupling neck adapted to insert into said coupling hole.
