The generator body 200 is fixedly connected with the mounting plate 100, and a rotation shaft of the generator body 200 passes through the mounting plate 100. When the miniature asynchronous generator is used, since the first gear 300 and the second gear 400 are already installed on the installation plate 100 in advance, the miniature asynchronous generator is not required to be installed in the space for installing the miniature asynchronous generator, namely, the situation that a worker is required to match the first gear 300 with the second gear 400 in the installation space is reduced, and the difficulty of installing the miniature asynchronous generator by the worker is further reduced.

When the second gear 400 rotates, the second gear 400 rotates relative to the rotating shaft 500, and the second gear 400 drives the first gear 300 to rotate. In the rotation process of the second gear 400, the rotation shaft 500 limits the movement of the second gear 400, so as to increase the stability of the second gear 400 during rotation.

In order to increase the stability of the first adjustment plate 610, a first locking assembly is provided on the first adjustment plate 610, and the first locking assembly is used for locking the first adjustment plate 610. When the distance from the rotating shaft 500 to the rotating shaft of the generator body 200 is adjusted, the first locking component is unlocked, the first locking component unlocks the first adjusting plate 610, then the first adjusting plate 610 slides, the first adjusting plate 610 and the mounting plate 100 slide relatively, and the first adjusting plate 610 drives the rotating shaft 500 to move; when the distance from the rotating shaft 500 to the rotating shaft on the generator body 200 is the desired distance, the sliding of the first adjusting plate 610 is stopped, and the first adjusting plate 610 is locked by using the first locking assembly, so that on one hand, the stability of the first adjusting plate 610 is increased, and on the other hand, the effect of conveniently adjusting the distance from the rotating shaft 500 to the rotating shaft of the generator body 200 by a worker is achieved.
