Patent number: 11541497Abstract: 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).Type: GrantFiled: November 18, 2015Date of Patent: January 3, 2023Assignee: SUZHOU CLEVA ELECTRIC APPLIANCE CO., LTDInventor: Fufei Wu
