The limiting convex ring 2 is close to the outward expansion section 21. A limiting ring groove is formed between the limiting convex ring 2 and the outward expansion section 21, and a reinforcement ring 3 is embedded in the limiting ring groove.

[0030] In order to limit the rotation of the reinforcement ring 3 in the limiting ring groove, a positioning structure 4 is provided on the tube body 1. The positioning structure 4 includes a convex strip 41 and a positioning groove 42. The positioning groove 42 is opened on the inner wall of the reinforcement ring 3, and a plurality of positioning grooves 42 are evenly distributed along the axis of the reinforcement ring 3. The convex strip 41 is fixed on the inner wall of the limiting ring groove, and a plurality of convex strips 41 are evenly distributed along the axis of the limiting ring groove. The length direction of the convex strip 41 is arranged along the axial direction of the tube body 1. One convex strip 41 is embedded in one positioning groove 42. The cross-sections of the convex strip 41 and the positioning groove 42 are both fan-shaped.

[0031] A placement groove 51 is opened on the inner wall of the reinforcement ring 3, and the placement groove 51 is filled with a thermal grease layer 52, so that the thermal grease layer 52 is in contact with the inner wall of the limiting ring groove to quickly transfer the heat of the tube body 1 to the reinforcement ring 3, thereby improving the heat dissipation and allowing the reinforcement ring 3 to be evenly heated.

[0032] The reinforcement ring 3 has a first extension section 61 at one end close to the expansion section 21 and a second extension section 62 at one end close to the stop convex ring 2. The outer diameter of the first extension section 61 is greater than the outer diameter of the second extension section 62. The inner wall of the first extension section 61 fits the outer wall of the expansion section 21.

[0033] A first guiding slope 611 is formed on the outer wall of the first extension section 61 , and the first guiding slope 611 faces the second extension section 62 . A second guiding slope 621 is formed on the outer wall of the second extension section 62 and is arranged opposite to the first guiding slope 611 .

[0034] Three reinforcement rings 7 are fixedly connected to the outer wall of the tube body 1, and the three reinforcement rings 7 are arranged along the axial direction of the tube body 1. A first groove 71 is formed between the reinforcement ring 7 and the limiting convex ring 2, and a second groove 72 is formed between two adjacent reinforcement rings 7, that is, there are two first grooves 71 and two second grooves 72 in total.
