Bendable tool shank with light means

A bendable tool shank comprising:

• a bendable rod member, said bendable rod member comprising a first metal connector at a first end thereof and a second metal connector at a second end thereof;
• a power source assembly rotatably coupled to first end of said bendable rod member, said power source assembly comprising an electrically insulative housing, a metal axle bearing mounted on said first metal connector of said bendable rod member inside the housing of said power source assembly to support said power source assembly on said bendable rod member for allowing rotation of said power source assembly on the first connector of said bendable rod member, at least one battery cell mounted inside the housing of said power source assembly, a power switch, and a circuit board mounted in the housing of said power source assembly, said circuit board having a positive terminal and a negative terminal respectively electrically connected to positive and negative terminals of said at least one battery cell through said power switch;
• and
• a light source assembly rotatably coupled to the second end of said bendable rod member, said light source assembly comprising an electrically insulative housing, a metal axle bearing mounted on the second metal connector of said bendable rod member inside the housing of said light source assembly to support said light source assembly on said bendable rod member for allowing rotation of said light source assembly on the second connector of said bendable rod member, and a light emitting element mounted in the housing of said light source assembly, said light emitting element having a first terminal electrically connected to said circuit board through an electric wire and a second terminal electrically connected to the metal axle bearing of said light source assembly such that said light emitting element is turned on/off when the user switched on/off said power switch.
