[0025] In the embodiment, the specific working principle is as follows: when used, water enters into left main spray pipe 4 and right main spray pipe 5 through main connecting pipe 1, and then the water is in a jet shape and contacts with the inclined surface formed on the surface of rocker arm 7 under the action of water pressure, at this time, rocker arm 7 is rotated under the impact force, one side of the rotating rocker arm 7 contacts with semisphere 15, at this time, semisphere 15 moves in the direction opposite to the impact force, and the semisphere 15 moves reversely under the action of telescopic spring 13, and then when rocker arm 7 contacts with semisphere 15, rocker arm 7 can be bounced away, and then the above process is repeated, so that the elastic stress of telescopic spring 13 can be effectively reduced, and when the elastic force of telescopic spring 13 is reduced, the telescopic spring 13 can be replaced by disassembling mounting body 10 from baffle 17, then releasing the clamping state of mounting tube 11 and mounting body 10, and then pulling out plug shaft 12, and then replacing telescopic spring 13, the above-mentioned method can prevent the problem that the elastic effect of spring is reduced due to high frequency of use in the prior art, and the problem that the spring is not convenient to replace and affects subsequent use.
