The utility model relates to the technical field of telescopic rods, in particular to a telescopic rod
assembly, a selfie rod and an umbrella rod device, which comprises a driving rod, unit rods are sequentially connected to form telescopic matching, a telescopic
pipe fitting is sleeved outside the driving rod and is formed by sequentially connecting unit pipes, and linear limiting parts are arranged on the unit pipes. The adjacent unit pipes are in linear telescopic fit through linear limiting parts, the driving thread pieces are located on the unit rods correspondingly, holes are formed in the
pipe walls of the unit pipes and spirally extend in the
pipe length direction of the unit pipes, the driving thread pieces are matched with the unit pipes correspondingly, thread protrusions are arranged outside the driving thread pieces, and the driving thread pieces are matched with the unit pipes. According to the telescopic rod
assembly, the threaded protrusion is matched with the hole of the unit pipe, the driving rod rotates, telescopic driving of the telescopic
pipe fitting is implemented by driving the threaded piece, the telescopic rod
assembly can achieve telescopic rod design of more stages more easily, when a larger
shooting range and higher flexibility are pursued, the requirement can be met by reasonably increasing the telescopic stages, and better expansibility is achieved.
