Abstract

The present disclosure relates to a power tool combination and a synchronization control device thereof including a first power tool, a second power tool, a signal receiving device electrically connected to the first power tool and a signal transmitting device electrically connected to the second power tool. The signal receiving device has a power switch for controlling the first power tool. The first aid second power tool are synchronously powered-on or powered-off via signal transmission and the signal transmitting device and the signal receiving device form independent circuits with the first and second power tools respectively. This makes the power of the power tool combination unlimited by the current capacity of the inlet wires of the power tools and lowers manufacturing costs.
