The beneficial effect of this scheme is: the impeller rotates to enable the crank to do circular motion so as to drive the rocker to do reciprocating motion, at the moment, the transition gear drives the driven wheel to rotate, because the driven wheel is connected with the two pawl mechanisms through the rotating shaft, and pawl directions of the two pawl mechanisms are opposite, when the driven wheel rotates intermittently, the driven wheel only rotates in one direction, so that only one side of the pawl mechanism is driven to rotate, and the pawl mechanisms drive the driven wheels to rotate respectively, so that the driven wheels charge the generator. The kinetic energy is converted into electric energy through the crank rocker mechanism and the characteristic of the reverse pawl, and the electric energy is stored in the storage battery for the small-sized sanding machine to move.

Further, the length relation of the crank, the rocker and the connecting rod is as follows: the crank is smaller than the connecting rod, and the connecting rod and the crank are made of harder and more wear-resistant materials.

The beneficial effect of this scheme is: the length setting makes the amplitude of the reciprocating motion of the rocker larger, the rotating amplitude of the pawl mechanism is also larger, and the efficiency of converting kinetic energy into electric energy is higher.

Further, the crank, the rocker and the connecting rod are made of medium carbon alloy steel.

The beneficial effect of this scheme is: because the sanding machine is characterized by self, stones needing sanding can impact the crank, the rocker and the connecting rod, so that the materials are hard and wear-resistant, and the medium carbon alloy steel is characterized by high strength, high toughness, wear resistance and corrosion resistance, so that the service lives of the crank, the rocker and the connecting rod are longer.

Further, the size of the upper hole of the outer groove just meets the swinging of the connecting rod.

The beneficial effect of this scheme is: the flying stones which are impacted by the impeller are reduced to the greatest extent and enter the outer groove, and equipment in the outer groove is damaged.

Further, the lower hole of the outer groove is positioned at the bottom of the outer groove.

The beneficial effect of this scheme is: the flyrock entering the outer groove can fall from the impeller to be sanded again, so that part of flyrock is prevented from being sanded because of entering the outer groove, and the sanding effect is poor.
