The embodiment of the invention provides a 10KV handcart switch simple electricity testing device. The device comprises an isolation baffle and a dead lock which is over against and parallel with the isolation baffle, wherein the surface of the isolation baffle is provided with at least one first electricity testing hole, the dead lock can slide relative to the isolation baffle, and at least one second electricity testing hole is arranged on the surface of the dead lock; one end of a resetting elastic device is fixed at one end of the dead lock, facing a sliding direction, the other end of the resetting elastic device is fixed at one end of the isolation baffle, a fixed end of a transformation mechanism is fixed on the dead lock, the transformation mechanism is used for pulling the dead lock to slide to an electricity testing operation position when the transformation mechanism is started, and the resetting elastic device is used for pushing the dead lock off from the electricity testing operation position when the transformation mechanism is closed; and only when the dead lock is located in the electricity testing operation position, the second electricity testing holes on the dead lock are respectively coincided with the first electricity testing holes on the isolation baffle one to one.
