    • A reciprocating saw blade for use with a reciprocating saw includes a body defining a longitudinal axis, an attachment portion configured to couple to the reciprocating saw, and a cutting portion formed on the body. The cutting portion includes a plurality of cutting teeth. Each cutting tooth includes a tip, a rake face extending from the tip generally toward the longitudinal axis and defining a gullet, and a relief surface extending from the tip. The blade also includes a plunge point formed on the body for initiating a plunge cut. The plunge point includes a leading tooth and a second tooth. The leading tooth includes a tip and a rake face extending from the tip generally toward the longitudinal axis and defining a leading gullet. The second tooth is positioned in the leading gullet adjacent the leading tooth and is generally smaller than the leading tooth and each cutting tooth.
    • 与往复锯一起使用的往复式锯片包括限定纵向轴线的主体,配置成耦合到往复锯的附接部分和形成在主体上的切割部分。 切割部分包括多个切割齿。 每个切割齿包括尖端,从尖端大致朝向纵向轴线延伸并限定齿槽的前刀面和从尖端延伸的浮雕表面。 刀片还包括形成在身体上用于引发切入的切入点。 插入点包括前牙和第二牙。 引导齿包括尖端和前刀面,前刀面从尖端大致向纵向轴线延伸,并且限定了前缘齿槽。 第二齿定位在与前牙相邻的前排槽中,并且通常小于前牙和每个切齿。

    • An impact device includes a housing, a motor supported by the housing, a stationary shaft, and a rotating transmission member supported on the stationary shaft for rotation. The rotating transmission member includes a hub having a first cam surface. The impact device also includes a rotating impact member carried by the transmission member and rotatable relative to the transmission member. The rotating impact member includes a lug protruding from an outer periphery of the rotating impact member and a second cam surface. The impact device further includes a spherical element engaged with the first and second cam surfaces on the hub of the rotating transmission member and the rotating impact member, respectively, an energy-absorbing member exerting a biasing force against the rotating impact member, and a reciprocating impact member oriented substantially normal to the stationary shaft and impacted by the lug of the rotating impact member.
    • 冲击装置包括壳体,由壳体支撑的马达,固定轴和支撑在固定轴上用于旋转的旋转传动构件。 旋转传递构件包括具有第一凸轮表面的轮毂。 冲击装置还包括由传动构件承载并可相对于传动构件旋转的旋转冲击构件。 旋转冲击构件包括从旋转的冲击构件的外周突出的凸耳和第二凸轮表面。 冲击装置还包括与旋转传动构件的轮毂和转动的冲击构件上的第一和第二凸轮表面接合的球形元件,对能够旋转的冲击构件施加偏置力的能量吸收构件, 撞击构件基本上垂直于固定轴定向并且被旋转的冲击构件的凸耳撞击。

    • A power tool having a paddle switch is configured to allow easier actuation of a switch mechanism. The power tool comprises a housing, a support surface disposed within the housing, a switch mechanism having a first position and a second position, a paddle member including an input surface and a hinge pin positioned a distance from the support surface, and a multiplier member pivotally connected to the hinge pin and having a first arm and a second arm. The first arm of the multiplier member extends from the hinge pin along a first longitudinal axis, and the second arm of the multiplier member extends from the hinge pin along a second longitudinal axis that is not parallel to the first longitudinal axis. The second arm is disposed to contact the support surface when force is applied to the input surface, causing rotation of the multiplier member about the hinge pin. The rotation of the hinge pin causes the first arm to contact the switch mechanism and move it from the first position to the second position.
    • 具有桨式开关的电动工具被配置为允许更容易地致动开关机构。 电动工具包括壳体,设置在壳体内的支撑表面,具有第一位置和第二位置的开关机构,包括输入表面和与支撑表面一定距离的铰链销的桨构件,以及乘法器构件 枢转地连接到铰链销并且具有第一臂和第二臂。 乘法器构件的第一臂沿着第一纵向轴线从铰链销延伸,并且乘法器构件的第二臂沿着不平行于第一纵向轴线的第二纵向轴线从铰链销延伸。 当力施加到输入表面时,第二臂设置成接触支撑表面,从而使乘法器构件围绕铰链销旋转。 铰链销的旋转使得第一臂接触开关机构并将其从第一位置移动到第二位置。
