[0070] The nozzle body 11 presses the second elastic member under the abutting action of the third adjusting member 3, and when the third adjusting member 3 is operated to move outward, the elastic force of the second elastic member is released, which can push the nozzle body 11 to automatically move towards the third adjusting member 3, thereby saving the time for the operator to operate the fourth adjusting member 4 and further saving the time for maintaining the nozzle 100.

[0071] In an embodiment, the second elastic member is an elastic plunger. In other embodiments, the second elastic member can be a spring or an elastic rubber member.

[0072] In an embodiment, the second adjusting part further comprises a stopper 5, the stopper 5 is installed on the adjusting seat 12, and the third adjusting member 3 has a locked state and an unlocked state.
