Abstract:
A hollow pipe joint structure for a sewing machine includes a first hollow pipe, a second hollow pipe and an elastic member. The elastic member is sleeved onto the first hollow pipe and the second hollow pipe, and elastically squeezes against the first outer surface and the second outer surface of the first and second hollow pipes, respectively, to pull the first and second hollow pipes against each other, which makes assembly of the hollow pipes easier, quicker and no frequent maintenance is required.
