The working principle is as follows: when the electric grinding machine works, firstly, the electric grinding machine is arranged at a proper position through the fixed frame 1, then, a power supply is switched on, the control switch is switched on, the motor in the shell 2 can drive the rotating shaft 6 to rotate along the inner side of the bearing 7, further, the grinding wheel 5 is driven to rotate, and a worker can finish the derusting of the mechanical parts by enabling the rusted mechanical parts to be close to the grinding wheel 5;

when the electric grinder is used and the bearing 7 is damaged, the rotation of the rotating shaft 6 can shake to cause the bearing 7 to generate internal stress to further impact the heat generating mechanism 9, at the moment, the vibrating block 95 can move along the groove 94 under the impact action of the internal stress, and further the vibrating block 95 can impact the metal sheet 92 to enable the metal sheet 92 to vibrate;

when the metal sheet 92 generates bending vibration, the vibration energy of the metal sheet is rapidly transmitted to the silicone rubber sheet 93 tightly attached to the outer side of the metal sheet 92, so that friction and mutual dislocation in the silicone rubber sheet 93 are caused, due to internal loss and large internal friction of the silicone rubber sheet 93, a considerable part of the vibration energy of the metal sheet 92 is lost and becomes heat energy to be dissipated to the inner side of the heat generating groove 91, so that the temperature in the heat generating groove 91 is increased, based on the characteristic of nitrogen gas filled in the heat generating groove 91, the volume of the nitrogen gas in the heat generating groove 91 is rapidly expanded along with the increase of the temperature in the heat generating groove 91, the pressure in the heat generating groove 91 is increased, and the electric contact 82 in the trigger mechanism 8 is acted by the extrusion force to be in contact with the conductive rail 83 along the inner wall of the connecting groove 81, so that a circuit where the conductive rail 83 is located is in a state of a passage;

at this moment, the electrode column 12 connected in series with the conductor rail 83 in the brake mechanism 10 can have current to pass through, and then the heating wire 13 on the inner side of the electrode column 12 can generate a large amount of heat, based on the characteristics of sodium azide, after the sodium azide receives the temperature stimulation higher than the melting point of the sodium azide, the sodium azide can explode, a large amount of nitrogen is generated, and then the brake block 14 pops up along the inner wall of the brake groove 11, and then the rotating shaft 6 is braked, meanwhile, the worker is reminded to turn off the power supply, and the electric grinder is overhauled.
