[0027] In the telescopic conduction connector described in this embodiment, relative telescoping can occur between the first pipe body 110 and the second pipe body 120, and positioning can be achieved through the locking assembly 200 when the predetermined length is reached. During this process, the pressing plate 220 drives the positioning pin 240 to cooperate with the positioning strip 130 through the reset member 230, so that it can be accurately and stably embedded in the corresponding positioning hole 132 when fixation is required, thereby realizing the adjustment of the length of the telescopic assembly 100.
