The outer ring wall of the second connecting tube 2 is provided with a mounting groove 208, and the mounting groove 208 is provided with an arc ring 209. The arc ring 209 is placed on the side of the top seat 207 away from the axis of the second connecting tube 2. A pressing plate is provided at the opening of the arc ring 209. The arc ring 209 is pinched to make the arc ring 209 squeeze the second connecting tube 2 and the multiple fixing plates 202, and the multiple fixing plates 202 are then closed to a certain extent, so that the subsequent fixing plates 202 enter the sliding windows 104 of the first connecting tube 1. When the multiple fixing plates 202 enter the multiple sliding windows 104 of the first connecting tube 1, the second connecting tube 2 will also be synchronously It contacts the first connecting pipe 1.
