| 188 | Control method for motor-driven shears | US12799347 | 2010-04-22 | US20100269355A1 | 2010-10-28 | Dezhong Yang; Junya Duan |
| The present invention relates to a control method for motor-driven shears. The control method for the motor-driven shears of the present invention requires that both the power supply module and the control system used to drive the motor be active simultaneously for the shears to operate. The power supply module requires a switch be pressed to activate the power supply module and to provide the resultant power to the MCU. Further, upon releasing the switch, the MCU is be able to maintain the power supply module in a discharging state long enough to allow the control system controlling the motor to rotate the movable blade to an open position. Finally, when the movable blade is opened to a maximum position, the MCU may direct the motor to stop rotation and shut off the power supply module. | ||||||

| To allow for starting and/or stopping an automatic scissor drive (6) during the cutting process according to the needs of the user, a push-button (19) is provided on one handle (4b) of a pair of scissors (1). When the cutting blades (3a,b) are closed by the user, such that an angle y is reached, the rubber block (14) pushes the push-button (19), thus starting a drive unit (6). In preferred embodiments, the drive unit (6) includes a motor (9) with an unbalance element (10) inducing vibrations in one of the blades (2a). The blades (2a,b) are coupled by the elastic rubber block (14), such that the scissors (1) act as an oscillating system.
