[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1 to 3 As shown, this embodiment includes a nozzle body 1, which is installed inside the guide tube 2 to form a core assembly structure. The guide tube 2 has a fixing hole 21 on its wall, and a long strip-shaped limiting window 11 is provided at the corresponding position of the nozzle body 1. The fixing pin 7 passes through the limiting window 11 and is fixedly connected to the fixing hole 21 at both ends. Through the cooperation of the fixing pin 7 and the limiting window 11, the axial movement stroke of the nozzle body 1 is restricted, and its coaxiality is ensured during the adjustment process.

[0016] like Figures 1 to 3 As shown, the adjustment assembly 3 includes an outer adjustment gear ring 31, an inner adjustment gear ring 32, and an adjustment gear 33. An external thread structure 12 is machined on the outer side of the middle section of the nozzle body 1. The inner adjustment gear ring 32 is sleeved on the outer side of the nozzle body 1 and meshes with the external thread structure 12 to achieve threaded transmission. The adjustment gear 33 meshes with the outer tooth surface of the inner adjustment gear ring 32, and an adjustment window 22 is correspondingly opened on the guide tube 2. The axle of the adjustment gear 33 passes through the adjustment window 22 and extends out partially. The outer adjustment gear ring 31 is sleeved on the outer side of the guide tube 2, and its inner tooth surface meshes with the outer tooth surface of the adjustment gear 33 to form a two-stage transmission structure. By rotating the outer adjustment gear ring 31, the inner adjustment gear ring 32 can be driven to rotate, thereby driving the nozzle body 1 to move axially.

[0017] like Figures 1 to 3 As shown, one end of the guide tube 2 narrows to form a guide nozzle 23, and the other end extends outward to form a threaded connector 24, providing a structural basis for fluid injection and adapter 6 connection. One end of the adapter 6 is sleeved on the outer end of the threaded connector 24 and fixedly connected to the guide tube 2. An annular sealing groove 61 is provided inside the adapter 61, and a third sealing ring 10 is installed in the sealing groove 61. The third sealing ring 10 is sleeved on the outside of the nozzle body 1 to further block the gap leakage between the nozzle body 1 and the adapter 6.

[0018] To elaborate further, such as Figures 2 to 3 As shown, a keyway 25 is provided on the outer side of the flow guide tube 2 along the axial direction, and a connecting key 41 is integrally formed on the inner side of the gripping sleeve 4. When the gripping sleeve 4 is sleeved on the outer side of the flow guide tube 2, the connecting key 41 and the keyway 25 are fitted together, which not only realizes the circumferential fixation of the gripping sleeve 4 and the flow guide tube 2, but also provides a stable gripping position for the user, and does not affect the rotation adjustment of the outer adjusting gear ring 31.

[0019] To elaborate further, such as Figure 1 and Figure 3As shown, from left to right, a first bushing 8 and a second bushing 9 are sequentially fitted and connected to the outer side of the nozzle body 1. A first sealing ring 81 is embedded in the inner ring of the first bushing 8, and a second sealing ring 91 is embedded in the inner ring of the second bushing 9. Both the first sealing ring 81 and the second sealing ring 91 are tightly fitted to the outer side of the nozzle body 1. The positioning effect of the bushing on the sealing ring enhances the sealing performance between the nozzle body 1 and the guide tube 2, preventing fluid leakage.

[0020] To elaborate further, such as Figures 2 to 3 As shown, the locking nut 5 is threadedly engaged with the threaded connector 24, and a split ring 51 is embedded inside it. The inner side of the split ring 51 is tightly fitted with the outer side of the guide tube 2. During the tightening process of the locking nut 5, the split ring 51 can disperse stress, enhance the connection stability, and facilitate subsequent disassembly and maintenance.
