In this embodiment, the locking ring 2 is an integrally formed structure and is made of an elastic material. The locking ring 2 is in a long strip-shaped structure when not mounted in the positioning sleeve 1 (refer to fig. 3), and before mounting, the locking ring 2 is curled into a circular ring structure and then is mounted in the positioning groove 11. Because the locking ring 2 is made of elastic material, when the locking ring 2 is installed in the positioning groove 11, the locking ring 2 is to be restored and expanded outwards, and the positioning ring 22 and the positioning claw 23 are elastically and tightly matched with the groove side wall 113 of the positioning groove 11, so that the locking ring 2 is clamped into the positioning groove 11, and further the locking ring 2 is prevented from easily falling out of the positioning groove 11. Further, the locking ring 2 is made of a spring steel material. In the process of installing the locking ring 2, the locking ring 2 can be wound into an annular structure with smaller volume in a winding mode, then the annular structure is plugged into the positioning groove 11, and when the acting force on the locking ring 2 is relieved by a user, the locking ring 2 can be automatically opened, so that the positioning groove 11 is tightly attached, and the installation process is simple and efficient. Meanwhile, the length of the unfolded locking ring 2 is determined by the circumference of the positioning groove 11, and can be set by a user according to the installation requirement. The user can also change the strength of inserting and pulling the wind nozzle 3 by adjusting the number of the elastic claws 21 and the elastic strength, and the adjustment of the elastic strength can be realized by changing the thickness, the bending angle and the material of the elastic claws 21.
In addition, as for the machining of the locking ring 2, the locking ring can be formed by only two simple machining processes of stamping and bending in sequence, the machining cost is low, and the control of the production cost of enterprises is facilitated.
Referring to fig. 5, the height sum h1 of the retainer ring 22 and the positioning pawl 23 (i.e., the vertical distance from the lower surface of the retainer ring 22 to the upper surface of the positioning pawl 23) is smaller than the height h2 of the positioning groove 11 (i.e., the vertical distance from the lower groove wall 111 to the upper groove wall 112 of the positioning groove 11), so that the locking ring 2 is in clearance fit with the positioning groove 11 to facilitate the loading of the locking ring 2 into the positioning groove 11. In this embodiment, h2—h1=0.1 mm. In practice, the difference in height between the two can be adjusted as required, and is not limited herein.
It should be noted that, the positioning ring 22 and the positioning claw 23 together form a positioning component, and in the actual use process, the positioning component only needs to be matched with the positioning groove 11 on the positioning sleeve 1, so that the locking ring 2 cannot be separated from the positioning sleeve 1 after the positioning component is mounted to the positioning groove 11, and the specific structure of the positioning component is not limited. For example, the positioning member only includes a positioning ring 22, and the positioning ring 22 is clamped in the positioning groove 11.

During the process of installing the wind nozzle 3, the stop edge 31 is gradually inserted into the locking ring 2, the elastic claw 21 gradually expands outwards under the pushing and resisting action of the stop edge 31, when the stop edge 31 passes through the elastic claw 21 along the inserting direction, the elastic claw 21 can reset under the elastic action so as to be elastically clamped on the outer circumferential surface of the connecting end of the wind nozzle 3, at this time, since the stop edge 31 protrudes out of the outer wall of the wind nozzle 3, the stop edge 31 can block the free end of the elastic claw 21 (namely, the end of the elastic claw 21 far away from the positioning ring 22) to prevent the wind nozzle 3 from being easily pulled out of the locking ring 2. In addition, during the process of inserting the wind nozzle 3 into the locking ring 2, the upper groove wall 112 of the positioning groove 11 can abut against the upper end surface of the stop edge 31, so as to limit the insertion stroke of the wind nozzle 3, and when the upper groove wall 112 abuts against the stop edge 31, the stop edge 31 passes through the elastic claw 21 along the insertion direction, and the elastic claw 21 at this time elastically abuts against the outer circumferential surface of the connecting end of the wind nozzle 3.
Further, the outer wall of the connecting end of the wind nozzle 3 is in transitional connection with the stop edge 31 through the cambered surface 311, the cambered surface 311 can prop against the free end of the elastic claw 21, when the wind nozzle 3 is pulled out by a user, the stop edge 31 can cause the elastic claw 21 to expand outwards under the action of the cambered surface 311, so that the stop edge 31 smoothly passes through the elastic claw 21 along the pulling-out direction, and the wind nozzle 3 can be pulled out from the locking ring 2 conveniently.
