In the present invention, a limit switch is assembled with and accommodated in a protective enclosure so as to supply or block the electric power of an operating motor that rotates a rotating millstone of a pulverizing device. A top lid is assembled with the pulverizing device and is attached thereto by means of rotation. At the same time, top and bottom press bars formed on the top lid are inserted in and introduced to top and bottom guide slots of the protective enclosure so as to operate the limit switch so that the electric power is supplied. When the top and bottom press bars are dislodged from the top and bottom guide slots of the protective enclosure through the reverse rotation of the top lid, the electric power of the limit switch is blocked. To achieve these objectives, the present invention provides a device for connecting electric power in a pulverizing device, the device comprising: top and bottom press bars protruding at one side of a top lid that is assembled with a pulverizing container by means of rotation in order not to be dislodged; a protective enclosure that is assembled with one side of a bottom body having a drive motor accommodated therein and is equipped with top and bottom guide slots connected with the top and bottom press bars, respectively, by means of rotation; and a limit switch that is assembled with the inside of the protective enclosure and is equipped with a limit exposed to the top and bottom guide slots. The electric power of the drive motor is connected when the top and bottom press bars are attached to the top and bottom guide slots of the protective enclosure and the limit of the limit switch is decreased. |
