The extended connection part 2 includes a connecting tube 201, a positioning ring 202, and an insertion connecting tube 203. The positioning ring 202 is arranged between the connecting tube 201 and the insertion connecting tube 203. A limiting ring 204 nested inside the bottom of the connecting tube 201 is provided at the upper end of the positioning ring 202. At least one elastic snap ring 205 is provided on the outer wall of the limiting ring 204. An annular clamping groove 206 engaged with the elastic snap ring 205 is provided on the inner wall of the bottom of the connecting tube 201.
