The rotary jet device further comprises a rotary sleeve body, the rotary sleeve body is movably arranged outside the middle barrel body in a sleeving mode and can rotate around the axis of the middle barrel body, jet flow holes are formed in the inner wall of the rotary sleeve body, and a certain included angle is formed between the jet direction of the jet flow holes and the radial direction of the rotary sleeve body so that the rotary sleeve body can be reversely pushed to rotate when liquid is jetted. A communicating channel for communicating an inner cavity of the middle barrel with the jet hole is formed in the middle barrel; the uppe
