With reference to fig. 2, the following describes the movement principle of the transmission: the water flow impacts the blades in the accommodating cavity, the blades drive the rotating shaft 31 to move around the axial direction (the direction perpendicular to the paper surface in fig. 3) and along the extending direction (the left and right direction in fig. 3) of the first through hole 23, in the rotating process of the rotating shaft 31, the rotating shaft 31 drives the sliding block 41 to rotate, one end of the first extending portion 434 is connected with the sliding block 41 so as to rotate along with the sliding block 41, the sliding of the rotating shaft 31 in the first direction also drives the sliding block 41 and the first extending portion 434 to slide in the first direction, and the first extending portion 434 moves in the first direction under the joint drive of the two movements. Taking the example that the end of the first extending portion 434 connected to the slider 41 moves leftwards along the first direction, in the above process, the included angle θ between the first extending portion 434 and the second extending portion 435 increases, the torsion portion 433 can store and release energy, and the torsion portion 433 can drive the end of the first extending portion 434 connected to the slider 41 to move rightwards along the first direction under the action of torque, so that the included angle θ between the first extending portion 434 and the second extending portion 435 decreases, and the slider 41 reciprocates back and forth along the extending direction of the first through hole 23.

According to the embodiment of the invention, the connecting piece is set to be the torsion spring, so that the impeller generates relative motion under the impact of water, and the impeller generates recovery motion under the action of the torsion spring, the automatic reciprocating motion of the impeller in the extending direction of the first through hole is realized, other external power sources are not needed, the driving direction is simple, the structure expansibility is stronger, and the cost is low.
