摘要

The present invention discloses an energy-saving electric circuit power source on/off device. An apparatus main body and a power-off device installed in the apparatus main body, wherein the power-off device includes a telescopic cavity installed in the apparatus main body. A power-off component is installed, and the power-off component includes a lifting block installed in the telescopic cavity, and powers off the electric circuit when the lifting block slides up and down in the telescopic cavity. Alternatively, a power-on operation can be performed, a locking device is installed in the left inner wall of the telescopic cavity, and the locking device locks the elevating block when the elevating block is descending in the telescopic cavity.
