For the battery 13 in this embodiment, 18500 lithium batteries were used.

Charging input is 5V 1A, the battery 13 is 18500/1200mAh, the charging time is 2 hours, and a 3.7V motor 280 is loaded; the main control board 1 (circuit board) stops working after the load current 3A continues for 3 seconds; after locking, the sliding can not be started, a key locking indicator lamp 16 (key locking icon) flashes 3 to prompt that the key is locked, and after unlocking, the sliding can be started; the plug and play function is provided, and the static power consumption is less than 50uA; the main control panel 1 (circuit board) has a charging voltage detection function, and when the charging voltage is larger than 6.5V, the circuit is protected from charging.

Example five: as shown in fig. 5, two icons may be provided on one side of the body 10 of the two photosensors 43 on the basis of the third or fourth embodiment, and each icon corresponds to one photosensor 43, which is convenient for the user to use. It is also to be noted that the two photoelectric sensors 43 are made of transparent material corresponding to the outer surface of the body 10, which is beneficial to mastering the internal conditions and better sensing human body signals.

The invention 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 the 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 photo sensor 43 receives the trigger signal, the photo sensor 43 receives the trigger signal within 1 second, and the photo sensor 43 loses the trigger signal, and the photo sensor 43 loses the signal within 1 second, the main control board 1 (including the main control MCU and the signal processing circuit) receives the signal to determine whether the signal meets the requirement, if not, the signal is invalid or misoperated (the signal is generated singly or simultaneously and determined to be invalid), if so, the main control board 1 drives the driving part (the micro motor) to start (the micro motor is determined to be started) through signal execution, and then the shearing mechanism in the machine body 10 is started, so that the normal operation is realized. As shown in fig. 9, the main body 10 of the present invention includes a display portion (display screen) connected to the control switch circuit structure 20, the display portion (display screen) is also connected to the main control board 1, which is favorable for displaying electric quantity, and the main control board 1 can perform charging management on the battery 13.

As shown in fig. 5, the MCU can be programmed to automatically lock the two photosensors 43 when the MCU is idle for 5 minutes, which is beneficial to preventing false triggering. The two photoelectric sensors 43 are preferably distributed vertically (or distributed horizontally), when unlocking is needed, only a finger needs to stay on the photoelectric sensors 43, the corresponding indicator light is turned on, when the finger is turned off after flickering for 3 times, unlocking and starting can be completed by sliding upwards, the photoelectric sensors 43 receive trigger signals, the trigger signals of the photoelectric sensors 43 are received within 1 second, the photoelectric sensors 43 lose the trigger signals, the photoelectric sensors 43 lose signals within 1 second, and then starting is judged, and signals are generated independently or simultaneously to judge that the signals are invalid. As shown in fig. 5, the red LED lamp is turned on when charging, and turned to green when fully charged, and if 20% (3.2V) of electricity is left for operation, the red LED lamp continuously flickers to prompt charging, and when the battery voltage is lower than 3V, the red LED lamp does not operate when starting, and flickers 5 to prompt charging.

As shown in fig. 5, the processes of power on/off and locking/unlocking of the present invention:

when the device is used for the first time, unlocking is required: in the implementation of the present invention, two photoelectric sensors 43 are vertically distributed in the machine body 10, and correspondingly, the machine body 10 is provided with the photoelectric sensors 43 corresponding to the icons, and the unlocking is completed when the fingers stay at the lower icon (shown) for 3 seconds and slide upwards, that is, the fingers stay at the lower photoelectric sensor 43 for 3 seconds, and then move from the lower photoelectric sensor 43 to the upper photoelectric sensor 43, so that the lower photoelectric sensor 43 senses the signals of the fingers, and then the upper photoelectric sensor 43 senses the signals of the slid fingers, and thus the unlocking is completed, and then the normal state is entered;

for two photosensors 43, it is assumed that the initial state is high for both photodiodes: the finger generates a low level through a first photoelectric tube (a photoelectric sensor 43 below) and sends the low level to an MCU (the MCU is internally stored with a programmed control program, namely a singlechip); the second photoelectric tube (the upper photoelectric sensor 43) generates a low level within 1 second, the first photoelectric tube (the lower photoelectric sensor 43) is reset, and the singlechip executes the action, which is the process of switching on and off; the finger sliding through the two photosensors 43 is effective for the time 1S.

When the use needs to be shut down: when the finger slides upwards on the lower icon, unlocking is completed, and the corresponding indicator lamp (operation icon) is displayed when the computer is started to operate; when the finger slides downwards on the upper icon, the shutdown is finished;

automatic locking: when no operation is performed for 5 minutes after shutdown, the lock state is automatically entered.

Standard parts used in the application file can be purchased from the market, the photoelectric sensing plate and the internal parts of the photoelectric sensor are all conventional models in the prior art, the internal structure of the photoelectric sensing plate and the internal parts of the photoelectric sensor belongs to the structure in the prior art, a worker can complete normal operation of the photoelectric sensing plate and the photoelectric sensor according to a prior art manual, and the circuit connection adopts a conventional connection mode in the prior art, so that specific description is not given.
