Connection combination structure with free-rotating waterproof lamp conductive module

A connection combination structure with free-rotating waterproof lamp conductive module, comprising a first light pole, a second light pole, and a lamp arranged on said first light pole and/or said second light pole, wherein:

• said first light pole comprises opposing first end and second end, an axially protruding plug-in post at the first end thereof, a terminal hole recessed at a terminal end of said plug-in post, a first conductive terminal set in said terminal hole, and an external thread portion and at least a first positioning portion provided on an outer circumferential wall of said plug-in post, said plug-in post being a cylinder made of an insulating material;
• said second light pole comprises opposing first end and second end, a plug hole axially recessed on the second end thereof, a second conductive terminal set in said plug hole, and a second positioning portion, an internal thread portion and an optical hole portion provided on an inner hole wall of said plug hole sequentially, said plug hole being a round hole made of an insulating material, the diameter of said optical hole portion being larger than the diameter of said internal thread portion and the diameter of said external thread portion;
• and
• wherein said plug-in post of said first light pole is inserted into said plug hole of said second light pole, and said first light pole and said second light pole are then rotated to cause said external thread portion to lock into said internal thread portion, and continue the rotation to let said external thread portion pass through said internal thread portion and then enter said optical hole portion, forming that said first light pole and said second light pole are rotatable in the circumferential direction to adjust the illumination direction of said lamp, and said first light pole and said second light pole are prohibited from being pulled apart directly, and thus said first positioning portion and said second positioning portion are locked with each other to form axial positioning, and said first conductive terminal and said second conductive terminal are connected to each other for supplying power to said lamp.
