When the connecting male head 3 and the protective tube 2 are inserted into the sleeve 2 5, the clamping piece 4 outside the protective tube 2 slides in the clamping groove 7 of the sleeve 2 5 and the clamping ring 8 for positioning and fixing. At this time, the clamping strip 10 at the right end of the sliding sleeve 2 5 slides in the sliding groove 9 of the clamping ring 8, and the left side of the clamping strip 10 slides to block the opening on the left side of the clamping groove 7, so that the clamping piece 4 of the protective tube 2 is engaged in the clamping groove 7, so as to realize the positioning and quick connection between the connecting male head 3 and the connecting female head 11, which is convenient for the operator to operate.

[0039] When the operator needs to rotate one end of the connector to better cope with water flow impact or flow direction change, the protective block 17 can be pressed to drive the connecting pipe 15 fixedly connected to the protective block 17, so that the connecting pipe 15 drives the toothed ring 14 to slide and then rotates after squeezing the spring 13 on the inner wall of the sleeve 1. When it is rotated to a suitable angle, the protective block 17 is released, and the elastic force of the spring 13 in the sleeve 1 drives the toothed ring 14 to slide and then engage with the toothed ring 2 16 fixed on the right side of the sleeve 1 in the sleeve 1, so as to automatically lock the angle of the connector after rotating one end, thereby preventing accidental loosening after turning.
