Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-Fig. 6 is please referred to, the utility model provides a kind of technical solution：A kind of Magnetomotive generator being easily installed turn Clamp mechanism, including main body 3 and arc spoiler 5, the inside of main body 3 are fixedly connected with fixing axle 2, and one end of main body 3 is fixed to be connected It is connected to commutator 6, is provided with ten copper wire 4 between commutator 6 and arc spoiler 5, and the outer surface of commutator 6 equidistant is consolidated Surely ten arc spoilers 5 are connected with, the both ends of fixing axle 2 are fixedly connected with that there are two bearings 1, and one end of bearing 1 is fixedly connected There is limited block 13, and limited block 13 is an integral structure with fixing axle 2, the other end of bearing 1 is fixedly connected with Fixing shrink ring 8, One side surface of Fixing shrink ring 8 is equidistant to be opened up there are four metal ball groove 9, and metal ball groove 9 is internally provided with metal ball 7, gold The inside center line position for belonging to ball 7 is provided with metal ball fixing axle 10, and the inside of metal ball fixing axle 10 is fixedly connected with spring 11, the both ends of spring 11 be fixedly connected there are two protrusion 12.
