1. An extending pole clamping device connecting an outer pole and an inner pole, comprising:
a main body mounted on one end of the outer pole that receives insertion of the inner pole;
a second body mounted on and surrounding the inner pole, wherein the second body is connected to the main body at a back portion and unconnected at a front portion, and the second body comprises dual ramps at a front side thereof; and
a clamping lever rotatably connected at a base thereof to the dual ramps of the second body to allow the clamping lever to rotate in a longitudinal direction of the outer pole and the inner pole;
wherein the base of the clamping lever and the dual ramps are configured such that, when the clamping lever is closed, the base of the clamping lever engages with the dual ramps to exert a clamping force on the inner pole; and when the clamping lever is open, the base of the clamping lever disengages with the dual ramps and the clamping force on the inner pole is released.
