Patent ID: 8901873

Claim:
A mechanical equipment comprising: a control device having a signal counter and a signal amplifier; a power device having: an output mechanism; and a power mechanism having: a power unit; and a rotary unit; wherein, the power unit connects with the rotary unit to provide the power to the rotary unit, and the rotary unit connects to the output mechanism for driving the output mechanism to move periodically; a positioning device fixed on the power device and having a sensing member and at least one sensed member, and one of the sensing member and the sensed member is fixed on the rotary unit, and the other of the sensing member and the sensed member is fixed on the output mechanism to move periodically as the output mechanism moving periodically; wherein, when each time the sensing member and the sensed member are located relatively at a predetermined position, the signal amplifier receives and processes a sensing signal generated when the sensing member senses the sensed member and forms a processed sensing signal, and the signal amplifier transmits the processed sensing signal to the signal counter, and the signal counter accumulates the number of the processed sensing signals and sends a predetermined control signal to the power mechanism when the number of the processed sensing signals received by the signal counter reaches a threshold value.
