The outer wall of the arc block 7 contacts the outer wall of the slider 8. The swivel 6 is rotated, and the slider 8 is squeezed by the arc block 7 to push the guide rod 18 to squeeze the return spring a9 to drive the clamping block 10 to fix the sleeve, so as to spray. The inner wall of the swivel 6 is elastically connected with a buckle assembly through a return spring b11. The buckle assembly includes a clamping block 12, one end of the return spring b11 is fixedly connected to the bottom end of the clamping block 12, and the other end of the return spring b11 is fixedly connected to the inner wall of the swivel 6. Pressing the clamping block 12 inwards can squeeze the return spring b11 to retract it. At the same time, the elastic force generated by the deformation of the return spring b11 gives the clamping block 12 an outward thrust to reset it. A clamping groove 13 is provided on the inner wall of the ring 5, and the outer wall of the clamping block 12 is clamped with the inner wall of the clamping groove 13. After the clamping block 12 is pressed inwards until it is released from the clamping groove 13, the swivel 6 can be rotated.

After fixation, release the clamping block 12, and the return spring b11 pushes it into the clamping slot 13 to fix the state of the clamping block 10. When the spraying angle needs to be adjusted, pull the pull rod 15 outward until the limit block 16 is disengaged from the limit groove 17, and rotate the pull rod 15 to drive the rotating shaft 3 and the fixed block 4 to rotate, and drive the entire circular ring 5 to change the angle of the clamped sleeve, so as to facilitate the spraying of the sleeve. After the adjustment is completed, release the pull rod 15, and the return spring c14 pulls the pull rod 15 to reset, and the limit block 16 is clamped into the limit groove 17 to fix the changed angle.
