[0036] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0037] Example 1

[0038] Reference Figure 1 , Figure 2 , Figure 3A purge tube telescopic adjustment structure 100 includes a first tube body 10, a second tube body 20 having one end extending into the first tube body 10 and capable of telescoping relative to the first tube body 10, a tightening ring 30 mounted on the first tube body 10 and having an opening, and a tightening adjustment assembly 40 mounted on the tightening ring 30 and used to control the tightening degree of the tightening ring 30;

[0039] Furthermore, the tightening adjustment assembly 40 includes a first connecting part 301 and a second connecting part 302 arranged at the opening of the tightening ring 30, a connecting rod 401 connected to the first connecting part 301 and the second connecting part 302, and a locking handle 402 connected to one end of the connecting rod 401, wherein a rotating shaft 403 is hinged on the locking handle 402, and the rotating shaft 403 is fixedly connected to the end of the connecting rod 401, and the end of the connecting rod 401 away from the locking handle 402 is provided with a limiting cover 404, and the limiting cover 404 is in conflict with the second connecting part 302. When the locking handle 402 rotates around the rotating shaft 403, the rotating shaft 403 of the locking handle 402 will pull the connecting rod 401, thereby relatively pulling the first connecting part 301 and the second connecting part 302, thereby narrowing the opening of the tightening ring 30, thereby reducing the diameter of the tightening ring 30.

[0040] Reference Figure 4 , Figure 5 One end of the locking handle 402 is a movable end 402a, and the other end is a connecting end 402b. The connecting end 402b is hinged to the rotating shaft 403. An extrusion portion 402c and a release portion 402d are provided at the connecting end 402b. The distance between the extrusion portion 402c and the central axis of the rotating shaft 403 is greater than the distance between the release portion 402d and the central axis of the rotating shaft 403.

[0041] Furthermore, when the tightening adjustment assembly 40 controls the tightening ring 30 to loosen, the release portion 402d of the locking handle 402 contacts the first connecting portion 301 or the second connecting portion 302. In this embodiment, the release portion 402d of the locking handle 402 contacts the first connecting portion 301.

[0042] When the tightening adjustment component 40 controls the tightening of the tightening ring 30, the extrusion portion 402c of the locking handle 402 conflicts with the first connection portion 301 or the second connection portion 302. In this embodiment, the extrusion portion 402c of the locking handle 402 conflicts with the first connection portion 301, and the opening gap of the tightening ring 30 is reduced. The tightening ring 30 is in a locked state, thereby holding and fixing the second tube body 20, so that the position of the second tube body 20 is fixed.

[0043] The purge tube telescopic adjustment structure 100 is arranged at the connection position of the first tube body 10 and the second tube body 20. When the tightening adjustment component 40 controls the tightening ring 30 to loosen, the release part 402d of the locking handle 402 conflicts with the first connection part 301 or the second connection part 302, and the second tube body 20 can be telescopically adjusted relative to the first tube body 10. When the tightening adjustment component 40 controls the tightening of the tightening ring 30, the extrusion part 402c of the locking handle 402 conflicts with the first connection part 301 or the second connection part 302, and the opening gap of the tightening ring 30 is reduced, thereby playing the role of clamping and fixing the first tube body 10 and the second tube body 20, ensuring that the position of the second tube body 20 is in a fixed state, and the second tube body 20 is easy to adjust in telescopic manner.

[0044] Furthermore, in some embodiments, a guide portion 50 is provided on one of the second tube body 20 and the tightening ring 30, and a guide groove 60 corresponding to the guide portion 50 is provided on the other of the second tube body 20 and the tightening ring 30; the guide portion 50 and the guide groove 60 are slidably matched. Specifically, in this embodiment, the guide portion 50 is installed on the inner wall of the tightening ring 30, and the guide groove 60 is provided on the outer surface of the second tube body 20. The guide groove 60 extends in the length direction of the second tube body 20. The guide portion 50 circumferentially limits the telescopic direction of the second tube body 20. When the second tube body 20 is telescopically adjusted relative to the first tube body 10, the second tube body 20 is prevented from rotating, thereby ensuring its telescopic stability.
