Startup control circuit, power tool, and startup control method thereof

A power tool, comprising:

• an action part;
• a battery pack, wherein the battery pack supplies power to the action part;
• a startup control circuit, comprising a first switch circuit, a DC conversion circuit, a main control unit, a second switch circuit, and a drive unit;
• wherein the first switch circuit is connected to the battery pack and the DC conversion circuit, wherein the first switch circuit is configured to activate the DC conversion circuit to supply power to the second switch circuit, the main control unit, and the drive unit after the first switch circuit is triggered, wherein the second switch circuit is connected to the battery pack and the main control unit, wherein the second switch circuit outputs different voltage waveforms based on different timing sequences of the first switch circuit being triggered, wherein the main control unit is configured to output a first drive command to the drive unit when receiving a first voltage waveform, wherein the first voltage waveform is a voltage waveform outputted by the second switch circuit when the second switch circuit first receives a current flowing from the DC conversion circuit, wherein the drive unit controls the action part to not work based on the first drive command.
