A combined electric tool coordination system includes a main tool (4) and an auxiliary tool (1). The main tool (4) and the auxiliary tool (1) coordinate for working. A load detection module (E1) is used to detect a load parameter that is generated when the main tool (4) operates, and send the load parameter to a central control module (E2). The central control module (E2) adjusts output power of the auxiliary tool (1). The central control module (E2) controls power of the auxiliary tool (1) to increase as the load parameter of the main tool (4) increases and decrease as the load parameter decreases. An automatic adjustment function of the auxiliary tool (1) is applied to a dust collector (1). When power of the main tool (4) increases, more dust and scraps are generated, suction of the dust collector (1) is automatically adjusted to be higher, and the demand of a large quantity of dust is satisfied; and when the power of the main tool (4) decreases, less dust and scraps are generated, power of the dust collector (1) automatically decreases, the suction is reduced, and the demand of a small quantity of dust is satisfied.
