    • A power tool has a motor housing that comprises housing halves arranged in the circumferential direction of a motor. A brush holder is disposed within the motor housing and serves to support brushes. The brush holder comprises holder halves that are arranged in the circumferential direction of the motor. In order to assemble the brush holder into the housing, one of the holder halves is set onto one of the housing halves. Thereafter, the rotor and the stator are set onto the one of the housing halves. Then, the other holder half is set onto the one of the holder halves and is joined thereto so as to form the brush holder. Finally, the other housing half is set onto the one of the housing halves and are joined thereto so as to form the motor housing.
    • 电动工具具有电动机壳体,其包括沿电动机的圆周方向布置的壳体半部。 电刷架设置在电动机壳体内并用于支撑电刷。 电刷架包括沿电动机的圆周方向布置的保持器半部。 为了将电刷架组装到壳体中,其中一个保持器半部被设置在其中一个外壳半部中。 此后,将转子和定子安装在外壳半部之一上。 然后,将另一个保持器一半设置在保持器半部中的一个上并连接到其上以形成电刷架。 最后,将另一个壳体半部设置在壳体半部中的一个上,并且连接到壳体半部以形成电动机壳体。

    • A pair of brush assemblies 1 for use in an electric power tool each includes a brush holder 2 in which a carbon brush is inserted, a pair of elastic strips 7 protruding from the outside lower edges of the brush holder 2. The elastic strips 7 are folded back inward of the brush holder 2 such that each of the strips has a tapering, V-shaped cross-section and has elasticity in the widthwise direction of the brush holder 2. A pair of brush holder mounts 14 are provided on a motor housing of the electric power too, on which the brush assemblies 1 are installed. Each brush holder mount 14 includes a pair of positioning slots 16 for receiving the elastic strips 7 of the brush holder 2. When fitted in the positioning slots 16, the elastic strips 7 securely engage the side walls of the slots so as to prevent unintended removal of the brush holders 2 from the brush holder mounts 14.
    • 用于电动工具的一对电刷组件1包括:电刷架2,其中插有碳刷,一对从电刷架2的外侧下缘突出的弹性带7.弹性带7 折叠到电刷架2的内侧,使得每个条具有锥形的V形横截面,并且在电刷架2的宽度方向上具有弹性。一对电刷架安装件14设置在电动机壳体 的电力,其上安装有刷组件1。 每个电刷架安装件14包括一对定位槽16,用于容纳电刷架2的弹性带7.当安装在定位槽16中时,弹性带7牢固地接合槽的侧壁,以防止意外的移除 的电刷架2从电刷架座14上移动。

    • A piping leakage detecting apparatus includes a high pressure gas supply source, a gas implement connected to the high pressure gas supply source via a pipeline, and a switching device mounted on the pipeline for selectively opening and closing the pipeline. A pressure detecting device is mounted between the gas implement and the switching device for detecting the gas pressure inside the pipeline. A leakage judging device is provided to judge that gas leaks when no gas is being used and when a pressure drop is detected based on an output from the pressure detecting device, while the pipeline is being opened and closed by the switching device.
