Disclosed is a telescopic tube assembly comprising: an inner tube (1) and a sliding module (2) fixedly connected to an end of the inner tube (1); the inner tube (1) being peripherally sleeved by an outer tube (3) capable of sliding on the sliding module (2); and the sliding module (2) comprising rolling elements (201) for the outer tube (3) to slide to realize tube extension. This product has at an end of the inner tube (1) the sliding module (2), which also can be used for connecting each inner tube (1). The inner tube (1) is peripherally sleeved by the outer tube (3) capable of sliding on the sliding module (2). The sliding module (2) is provided with multiple rolling elements (201), by means of which the outer tube (3) can slide. The rolling of the rolling elements can realize tube extension, reducing the sliding friction of the outer tube, and making tube extension easier and more convenient.
