based on the above, when the power line 21 moves under the action of wind force, the power line 21 inside the device main body 1 also moves, and the arc piece 42 and the fuse piece 43 are designed so that the power line 21 moves without pulling the connection part of the power line 21 and the electronic component inside the device main body 1, thereby avoiding the loose fracture of the connection part of the power line 21 and the electronic component inside the device main body 1 caused by the movement of the power line 21 under the action of wind force, and facilitating the long-term use of the device;
based on the above, when the electronic component inside the device is shorted or the external device is shorted with the device through the power line 21, a large amount of current is generated along the power line 21, so as to generate a large amount of heat, and the fuse piece 43 is fused by the large amount of heat, at this time, the arc piece 42 loses the limit of the fuse piece 43, the arc piece 42 is fixedly connected with the T-shaped arc rod 52 and is extruded by the reset spring, the T-shaped arc rod 52 is made of insulating high temperature resistant material, and extends between the two groups of metal sheets 51, so as to cut off the power, thereby being capable of timely reducing the damage of the device caused by the short circuit and the fire hazard caused by the damage, and being more economical and safe.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
