Technical Field

[0001] The utility model relates to the technical field of power lines, in particular to a linkage control power line and a linkage control structure of an electric tool and its auxiliary equipment. Background Art

[0002] In the prior art, power cords, especially power cords for electric tools, generally only have the functions of power supply access and single on / off control of a machine device.

[0003] However, many power tools require external auxiliary equipment when in use. For example, power tools such as slotters, angle grinders, and water drills sometimes require external auxiliary equipment such as blowers or water pumps. To use them, you typically need to first turn the power tool on using the switch on the power tool, then use the switches on the blower or water pump to turn them on and off. Similarly, to turn them off, you also need to use the switches on their respective bodies to control them off. This makes operation very inconvenient, and it's even easy to forget to turn off the auxiliary equipment after turning off the power tool, resulting in a waste of power.

[0004] Therefore, it is necessary to develop a power cord with a linkage control function to be applied to a power tool with an auxiliary device, so that the power tool and its auxiliary device can be controlled on and off at the same time by turning on and off a switch. Utility Model Content
