    • A female coupler suitable for use with a high pressure fluid is provided. The female coupler has locking members or balls adapted to be forced into engagement with a male coupler inserted into the female coupler by a sleeve or outer movable member. The sleeve is held by holding members or balls until the male coupler is inserted into the female coupler and a locking ball receiving recess formed in the exterior surface thereof is brought into a position for receiving the locking balls therein. Accordingly, the sleeve is prevented from moving to a position for forcing the locking ball into the locking ball receiving recess even if the male coupler is suddenly moved out from the female coupler, which is a problem that can occur in prior art female couplers. Further, the sleeve is provided with handle. An operator can grip the handle to hold the female coupler and align it with the male coupler, and advance the former towards the latter so that male coupler is inserted into the female coupler and, then, the sleeve is moved to the locking position.
    • 提供适合与高压流体一起使用的母连接器。 阴联接器具有锁定构件或球,其适于被套筒或外部可移动构件强制与插入阴联接器的阳联接器接合。 套筒由保持构件或球保持,直到阳联接器插入阴连接器中,并且形成在其外表面中的锁定球容纳凹槽被带入其中接收锁定球的位置。 因此,即使公母耦合器从母耦合器突然移出,也阻止了套筒移动到用于迫使锁定球进入锁定球接收凹部的位置,这是现有技术的母耦合器中可能出现的问题。 此外,套筒设置有把手。 操作者可以握住手柄以保持阴联接器并将其与阳联接件对准,并使前者向后推进,使得阳联接器插入阴连接器中,然后将套筒移动到锁定位置。

    • An electric drill apparatus having a low profile is provided which comprises an annular cutter, a motor for rotating the annular cutter, a rotary shaft assembly for rotating the annular cutter attached to its leading end about a rotating, a rotation reduction mechanism disposed between the motor and rotary shaft assembly for transmitting a driving force of the motor to the annular cutter through the rotary shaft assembly, a feed mechanism responsive to an operation of a manual handle, for moving the rotary shaft assembly along with a straight line to advance or retract the annular cutter attached to the rotary shaft assembly with respect to a workpiece, and an adhesion base for securing the electric drill apparatus to the workpiece. The annular cutter has a plurality of cutting blades comprised of cemented carbide tips fixed on its lower end, thereby it is capable of rotating at a high speed. The rotary shaft assembly has a rotating shaft which rotates in a direction different from that of a rotating shaft of the motor, thereby the drill apparatus has a low profile.
    • 提供一种具有低轮廓的电钻装置,其包括环形切割器,用于旋转环形切割器的马达,用于旋转安装在其前端周围的旋转的环形切割器的旋转轴组件,设置在马达 以及用于通过旋转轴组件将电动机的驱动力传递到环形切割器的旋转轴组件,响应于手动手柄的操作的进给机构,用于沿着直线移动旋转轴组件以推进或缩回 环形切割器相对于工件附接到旋转轴组件,以及用于将电钻装置固定到工件的粘合基座。 环形切割器具有多个切割刀片,其由固定在其下端上的硬质合金刀头组成,从而能够高速旋转。 旋转轴组件具有沿与电动机的旋转轴不同的方向旋转的旋转轴,从而钻具具有低轮廓。
