The utility model is different from other products in that two sensors are used for judging photoelectric signals, and the interference of other objects on a circuit is reduced through simple operation logic, so that false touch opening is prevented; the operating principle of the control switch circuit arrangement 20 is: as shown in fig. 8 and 9, when the trigger signal of the photoelectric sensor 43 is received within 1 second, the trigger signal of the photoelectric sensor 43 is received, and at the same time when the trigger signal is lost by the photoelectric sensor 43, the signal is received by the main control board 1 (including the main control MCU and the signal processing circuit) to determine whether the signal meets the requirement, if not, the signal is invalid or misoperated (the signal is generated singly or simultaneously to determine that the signal is invalid), if so, the main control board 1 drives the driving part (the micro motor) to start up (the micro motor is judged to start up) through the signal execution, and then the shearing mechanism in the machine body 10 is started, thereby realizing normal operation.

As shown in fig. 5, the switching on/off and locking/unlocking processes of the present utility model:

when the unlocking is needed for the first use: because the two photoelectric sensors 43 are vertically distributed in the machine body 10 in the implementation of the utility model, the photoelectric sensors 43 corresponding to the icons are arranged on the machine body 10 correspondingly, unlocking is completed when a finger stays at the lower icon (shown) for 3 seconds and slides upwards, namely the finger stays at the lower photoelectric sensor 43 for 3 seconds, then the lower photoelectric sensor 43 moves to the upper photoelectric sensor 43, so that the lower photoelectric sensor 43 senses signals of the finger, then the upper photoelectric sensor 43 senses signals of the sliding finger, and the unlocking is completed, and the normal state is entered at the moment;

for the two photosensors 43, it is assumed that the initial state two photocells are high: the finger generates low level through the first photoelectric tube (the photoelectric sensor 43 below) and sends the low level to the MCU controller (the MCU microcontroller stores a well-programmed control program, namely a singlechip); the second photoelectric tube (the photoelectric sensor 43 above) generates a low level within 1 second, and the first photoelectric tube (the photoelectric sensor 43 below) is reset, and the singlechip performs an action, namely a process of starting and stopping; the finger sliding is active for time 1S through both photosensors 43.

When in use, the machine needs to be shut down: when the finger slides upwards on the lower icon, unlocking is completed, and the corresponding indicator lamps (running icons) are displayed when the user starts up and runs; and when the finger slides downwards on the upper icon, the shutdown is completed;

automatic locking: and when the machine is not operated for 5 minutes after shutdown, the machine automatically enters a locking state.
