What is claimed is: 1. An electric shaving device, comprising: a shaving body having a shaving head; a power supply received in said shaving body; a motor supported in said shaving body to electrically connect with said power supply, wherein said motor has a motor shaft rotatably extended at said shaving head; a shaving assembly comprising at least a first shaving blade rotatably supported at said shaving head and at least a second shaving blade rotatably supported at said shaving head at a position parallel to said first shaving blade; and a gear arrangement comprising a motor gear coaxially mounted at said motor shaft, a first gear supported underneath said first shaving blade to rotatably engage with said motor gear, a driving gear coaxially mounted to said first gear, and a second gear supported underneath said second shaving blade to rotatably engage with said driving gear, wherein when said motor gear is driven to rotate via said motor through said motor shaft, said first and second gears are driven to rotate in opposite direction, such that said first and second shaving blades are synchronically rotated in a bidirectional manner. 2. The electric shaving device, as recited in claim 1, wherein said shaving assembly further comprises an additional first shaving blade and an additional second shaving blade, wherein said two first shaving blades and said two second shaving blades are positioned at said shaving head in a diagonal manner, wherein said gear arrangement further comprises an additional first gear supported underneath said additional first shaving blade to rotatably engage with said motor gear and an additional second gear supported underneath said additional second shaving blade to rotatably engage with said driving gear, wherein when said motor gear is rotated, said two first gears and said second gears are driven to rotate in opposite direction such that said first shaving blades are synchronically rotated in one direction while said second shaving blades are synchronically in an opposed direction. 3. The electric shaving device, as recited in claim 1, wherein said first and second shaving blades are positioned at said shaving head at a same planar direction. 4. The electric shaving device, as recited in claim 1, wherein a diameter of said second gear is larger than a diameter of said first gear. 5. The electric shaving device, as recited in claim 2, wherein a diameter of each said second gear is larger than a diameter of said each first gear. 6. The electric shaving device, as recited in claim 3, wherein a diameter of said driving gear is larger than a diameter of said first gear. 7. The electric shaving device, as recited in claim 1, wherein said second gear has the same diameter as said driving gear. 8. The electric shaving device, as recited in claim 2, wherein each said second gear has the same diameter as said driving gear. 9. The electric shaving device, as recited in claim 3, wherein said second gear has the same diameter as said driving gear. 10. The electric shaving device, as recited in claim 6, wherein said second gear has the same diameter as said driving gear. 11. The electric shaving device, as recited in claim 1, wherein said power supply comprises a rechargeable battery disposed in said shaving body to electrically connect to said motor. 12. The electric shaving device, as recited in claim 2, wherein said power supply comprises a rechargeable battery disposed in said shaving body to electrically connect to said motor. 13. The electric shaving device, as recited in claim 3, wherein said power supply comprises a rechargeable battery disposed in said shaving body to electrically connect to said motor. 14. The electric shaving device, as recited in claim 6, wherein said power supply comprises a rechargeable battery disposed in said shaving body to electrically connect to said motor. 15. The electric shaving device, as recited in claim 10, wherein said power supply comprises a rechargeable battery disposed in said shaving body to electrically connect to said motor. 16. The electric shaving device, as recited in claim 1, further comprising a blade guider mounted on said shaving head to protect said shaving assembly, wherein said blade guider has a plurality of shaving slots formed thereon to communicate said first and second shaving blades with outside. 17. The electric shaving device, as recited in claim 2, further comprising a blade guider mounted on said shaving head to protect said shaving assembly, wherein said blade guider has a plurality of shaving slots formed thereon to communicate said first and second shaving blades with outside. 18. The electric shaving device, as recited in claim 3, further comprising a blade guider mounted on said shaving head to protect said shaving assembly, wherein said blade guider has a plurality of shaving slots formed thereon to communicate said first and second shaving blades with outside. 19. The electric shaving device, as recited in claim 10, further comprising a blade guider mounted on said shaving head to protect said shaving assembly, wherein said blade guider has a plurality of shaving slots formed thereon to communicate said first and second shaving blades with outside. 20. The electric shaving device, as recited in claim 15, further comprising a blade guider mounted on said shaving head to protect said shaving assembly, wherein said blade guider has a plurality of shaving slots formed thereon to communicate said first and second shaving blades with outside.
