Abstract
A telescopic tube assembly includes a first tube and a second tube penetrated in the first tube. A handle is pivoted to a base sleeved on the first tube and pressed against the second tube when the handle is locked. Further, a pin is provided between the base and a cover mounted to the base, and a button is horizontally disposed in the base. When the button is pressed, the pin is pushed by the button to be disengaged from the second tube, such that the length of the second tube can be adjusted. When the button is released, the pin is pushed by an elastic member to be engaged with the second tube for locking the second tube in a desired length. By means of the dual lock design, the telescopic tube assembly of the present invention provides good positioning effect to reduce operational risk.
