In this embodiment, a convex ring 35 is integrally formed at one end of the outer wall of the connecting tube, and an external thread 36 is provided on the outer wall of the connecting tube close to the convex ring. During installation, the end of the connecting tube away from the convex ring is inserted into the telescopic tube body, and the threaded clamp is threadedly connected to the external threads of the telescopic tube body and the connecting tube for positioning. Since the threaded clamp is threadedly connected to the telescopic tube body and the connecting tube respectively, the reliability of the connection between the two can be ensured to prevent loosening or falling off.

[0049] In actual application, an annular groove 5 is provided on the outer wall of the convex ring; an insertion cavity 6 is provided at one end of the snap connector, and a locking slot 7 is provided on the side wall of the insertion cavity; during installation, the convex ring is inserted into the insertion cavity of the snap connector, and the locking piece passes through the locking slot and is locked into the annular groove for positioning. In this embodiment, the outer diameter of the convex ring matches the inner diameter of the insertion cavity. After installation, the locking piece is used to lock the position, which can ensure the stability of the connection. Moreover, since it is an annular groove, the locking position can be rotated in the annular groove, so that the snap connector can also be rotated on the connecting pipe, which improves the convenience and stability of installation.

[0050] In actual application, the locking piece 31 includes a sheet body 311 and an elastic piece 312 integrally formed with symmetrical edges of the sheet body; the locking piece is inserted into the annular slot and is limited by the elastic piece. The elastic piece can be abutted after installation to prevent the locking piece from falling off the locking slot of the insertion cavity, thereby improving the stability and reliability of installation.
