Electric scissors are hand-held electric tools that are powered by a motor and drive the working head through a transmission organization to perform cutting operations. The electric scissors are composed of a motor, a gearbox, an eccentric shaft-link organization, a switch, a non-reconnectable plug and a knife.
Working principle of electric scissors:

The motor drives the eccentric shaft-connecting rod organization through the gearbox, so that the cutter bar drives the upper cutter head to make reciprocating branches, and the lower cutter head is fixed on the cutter holder. The power cord is a double-core sheathed flexible cable, which can not be reconnected with a double-post rubber plug.
  
Electric scissors operation method
  
1. Charge the battery for 5 hours first (12 hours for the first charge)
 
2. Before using the device, unplug the charger and disconnect the device from the charger (the device will not work when it is connected to the charger)
 
3. Remove the blade guard
 
4. Turn on the power manually. 5. Before starting cutting, let the cutting blade work for a few seconds without load, and listen to whether the sound is noisy, too slow or too fast.
