    • A power tool and a power cord. The power tool comprises a housing defining a housing thread, an electric motor, an electric circuit connected to the motor, a power cord removably connectable with the housing, the cord being connectable to a power source and to the circuit to connect the circuit to the power source, and a locking assembly for locking the power cord to the housing and to the circuit. The cord includes a cord electrical connector, and a mounting portion defining a cord thread, the cord thread being complementary to and engageable with the housing thread. The locking assembly includes a first locking member supported by one of the housing and the mounting portion, and a second locking member supported by one of the housing and the mounting portion, the first locking member being movable between a locking position, in which the first locking member engages the second locking member, and an unlocked position, in which the first locking member is disengaged from the second locking member. To connect the cord to the housing and to the circuit, the cord electrical connector is electrically connected to the circuit, the mounting portion is engaged with the housing to engage the cord thread and the housing thread, and the first locking member is moved to the locking position so that the first locking member engages the second locking member to prevent the cord thread and the housing thread from being disengaged.
    • 电动工具和电源线。 电动工具包括限定壳体螺纹的壳体,电动机,连接到电动机的电路,可拆卸地与壳体连接的电源线,所述电缆可连接到电源和电路以将电路连接到 电源和用于将电源线锁定到壳体和电路的锁定组件。 绳索包括绳索电连接器和限定绳索螺纹的安装部分,绳索与壳体螺纹互补并与壳体螺纹啮合。 所述锁定组件包括由所述壳体和所述安装部分中的一个支撑的第一锁定构件以及由所述壳体和所述安装部分中的一个支撑的第二锁定构件,所述第一锁定构件可在锁定位置之间移动,在所述锁定位置, 锁定构件接合第二锁定构件和解锁位置,其中第一锁定构件从第二锁定构件脱离。 为了将电线连接到壳体和电路,电缆电连接器电连接到电路,安装部分与壳体接合以接合线缆和壳体线,并且第一锁定构件被移动到 锁定位置使得第一锁定构件接合第二锁定构件以防止绳索线和壳体线脱离。
