    • A power-driven hammer drill 1 includes a rotary lever 8 for transmitting and disabling the transmission of the rotation of a motor 5 to a tool bit 4 and a slide lever 9 for transmitting and disabling the transmission of hammer blows to the tool bit 4. The rotary lever 8 is formed with a chamfer 52, whereas the slide lever 9 is formed with a straight portion 54 and a cut-out 53 which conforms to the circular edge of the rotary lever 8. When the slide lever 9 is in the lowermost position with the rotary lever 8 fitted in the cut-out 53, the rotary lever 8 is in the position to disconnect the rotation of the motor 5 to the tool bit 4, and while in this position, the slide lever 9 cannot be slid to its uppermost position, in which hammer blows cannot be transmitted to the tool bit 4. When the slide lever 9 is located in the uppermost position and the chamfer 52 of the rotary lever 8 is in the rearmost position, in which hammer blows cannot be transmitted to the tool bit 4 but rotation can be transmitted to the tool bit 4, the straight portion 54 opposes the chamfer 52 across a narrow gap so that the rotary lever 8 cannot be rotated to the rotation disabling position.
    • 电动锤钻1包括用于传送和禁止马达5的旋转传递到工具钻头4的旋转杆8和用于传递和禁止锤击锤击向工具钻头4的滑动杆9。 旋转杆8形成有倒角52,而滑动杆9形成有与旋转杆8的圆形边缘一致的直线部分54和切口53.当滑动杆9处于最下方时 旋转杆8安装在切口53中的位置,旋转杆8处于将马达5的旋转与工具4断开的位置,而在该位置,滑动杆9不能滑动到 其最高位置,其中锤击不能传递到工具钻头4.当滑动杆9位于最高位置并且旋转杆8的倒角52处于不能传递锤击的最后位置时 到工具位4但旋转可以 传递到工具位4,直线部分54跨过窄间隙与倒角52相对,使得旋转杆8不能旋转到旋转禁止位置。

    • The heat source apparatus is positioned at an outer peripheral portion of a rotative drum and an upper portion of an inhale port member of a drum supporting member for supporting the rotative drum. The heater of the heat source apparatus is positioned at an axial direction of a rotational axis of the rotative drum within a heater case. The heat source apparatus is installed at an upper corner portion of an outer frame with a heater case supporting member. The heat source apparatus and the inhale port of the drum supporting member are communicated with a C-shaped form duct. The apparatus offers the advantage that the back flow and the accumulation of the lint etc. generated from the clothes in the rotative drum to the heat source apparatus can be prevented.
    • 热源装置位于旋转鼓的外周部分和鼓支撑构件的吸入口构件的上部,用于支撑旋转滚筒。 热源装置的加热器位于加热器壳体内的旋转滚筒的旋转轴线的轴向方向。 热源装置安装在具有加热器壳体支撑构件的外框架的上角部。 鼓支承构件的热源装置和吸入口与C形导管连通。 该装置具有以下优点:可以防止从旋转滚筒中的衣服到热源装置产生的绒毛等的回流和积聚。
