WIPO Patent Application WO/2021/169346

A1

An adapter (100) of an electric tool and an electric tool system, relating to the field of electric tools. The adapter (100) of an electric tool comprises: a housing (1) having a first opening (11); a control module (2) used for controlling working parameters of a brushless motor of an electric tool (200); a first plug-in structure (3) provided in the housing (1) at the position corresponding to the first opening (11) and used for plug-in with the electric tool (200), the first plug-in structure (3) being electrically connected to the control module (2); and a shielding mechanism switching between a shielding state and an open state. When the adapter (100) is plugged into the electric tool (200), the shielding mechanism is in the open state, and the first opening (11) is open. When the adapter (100) is disconnected from the electric tool (200), the shielding mechanism is in the shielding state, and the first opening (11) is shielded. The shielding mechanism comprises a shielding member (4) and a reset member (5). The adapter (100) further comprises a switch unit (6) and an input wire (7). The adapter (100) can prevent dust, impurities and the like from entering a connecting socket, thereby effectively improving the safety factor.
