    • A dust collection nozzle (12) is provided through the upper blade guard 7 of a circular saw (1). The dust collection nozzle (12) includes a flared, horn-shaped dust capturing section (13) having a rectangular opening at the front end thereof, and a cylindrical dust outlet tube (14) connected to the rear end of the dust capturing section (13). Throughout cutting operations, the opening (16) remains directed toward the lower portion of the saw blade (8) so as to collect dust and other debris generated from a saw blade (8) rotatable attached to the upper blade guard. The dust collection nozzle (12) also includes a pair of dust guide plates (17, 18) formed on and extended from the opening (16). The dust guide plates (17, 18) extend in parallel to each other so as to interpose the saw blade (8) therebetween. Furthermore, provided to the right of the dust guide plate (18) is a flow straightening plate (19) extending in parallel to plates (17) and (18) from the upper to lower edges of the opening (16). Also, the flow straightening plate (19) extends into the dust capturing section (13), thus partitioning the dust collection passage into two sections, and terminates at the boundary between the capturing section (13) and the dust outlet tube (14). The plates (17) and (19), and the dust capturing section (13) jointly define an air flow cavity (20). The flow straightening plate (19) divides the opening closer to the right side edge of the opening (16) than the left side edge in order to widen the air flow cavity (20).
    • 通过圆锯(1)的上刀片护罩7设置集尘喷嘴(12)。 集尘喷嘴(12)包括在其前端具有矩形开口的喇叭形的喇叭形灰尘捕获部分(13)和连接到灰尘捕获部分的后端的圆柱形灰尘出口管(14) 13)。 在切割操作期间,开口(16)保持指向锯片(8)的下部,以便收集从可旋转地附接到上刀片护罩的锯片(8)产生的灰尘和其它碎屑。 集尘喷嘴(12)还包括形成在开口(16)上并从开口延伸的一对灰尘引导板(17,18)。 灰尘引导板(17,18)彼此平行延伸,以将锯片(8)插入其间。 此外,设置在尘埃导向板(18)的右侧的是从开口(16)的上边缘到下边缘平行延伸到板(17)和(18)的流动矫直板(19)。 此外,流动矫直板(19)延伸到灰尘捕获部分(13)中,从而将灰尘收集通道分成两部分,并且终止在捕获部分(13)和灰尘出口管(14)之间的边界处。 板(17)和(19)和灰尘捕获部分(13)共同限定了气流腔(20)。 为了加宽气流腔(20),流动整流板(19)将开口部分比开口部(16)的右侧边缘分割为左侧边缘。

    • The present invention provides an improved biscuit jointer which allows a ruler guide to be kept completely level during fine adjustment of the vertical position and angular orientation of the ruler guide with respect to a ruler and accurately abuts against a workpiece. The biscuit jointer of the invention includes: a circular cutter blade; a base accommodating the cutter blade; a housing containing a motor for driving the cutter blade and being slidable relative to the base; a ruler disposed on one end of the base to abut against an end face of a workpiece; and a ruler guide vertically slidable along the ruler. The ruler has a vertically extending slide edge plane on a predetermined end thereof, and the ruler guide has a linear guide on the predetermined end thereof, which slides against the slide edge plane. The ruler grade further includes a spur gear engaging with a toothed rack formed on the ruler, which allows vertical movement of the ruler guide along the ruler. A leaf spring applies pressure against the contact of the linear guide with the slide edge plane to secure the attachment of the ruler guide to the ruler. The biscuit jointer is further provided with a clamp to restrain the movement of the ruler guide relative to the ruler.
    • 本发明提供了一种改进的饼干接合器,其允许标尺引导件在垂直位置的精细调节和标尺引导件相对于尺的角度定向精确调节期间保持完全水平并且精确地抵靠工件。 本发明的饼干接头包括:圆形切割刀片; 容纳切割刀片的基座; 壳体,其包含用于驱动所述切割刀片的马达,并且能够相对于所述基座滑动; 设置在所述基座的一端上以与工件的端面抵接的标尺; 以及沿尺子垂直滑动的尺子指南。 标尺在其预定的端部上具有垂直延伸的滑动边缘平面,并且标尺引导件在其预定端部上具有线性引导件,该引导件抵靠滑动边缘平面滑动。 标尺等级还包括与形成在尺上的齿形齿条接合的正齿轮,其允许标尺引导件沿着标尺的垂直运动。 板簧对直线导轨与滑动边缘平面的接触施加压力,以固定标尺导轨与尺子的连接。 饼干连接器还设置有夹具以限制尺尺导轨相对于尺子的移动。

    • An electrical power tool may include a base capable of contacting the work-piece, a tool main body detachably attached to the base, and an elevating mechanism that is capable of changing a relative position of the tool main body to the base. The elevating mechanism includes a male elevating member that is releasably integrated with the tool main body, a female elevating member that is attached to the base and is capable of relatively raising and lowering the male elevating member, and an integrating mechanism that is capable of releasably integrating the male elevating member with the tool main body. The tool main body is capable of being removed from the base while the male elevating member is left in the base when the male elevating member is released from the tool main body by operating the integrating mechanism.
