    • A power saw tool including a housing, a motor, and a reciprocating shaft. A blade clamp assembly is mounted to the reciprocating shaft and adapted for gripping a saw blade. The blade clamp assembly includes a main body defining a channel for engaging the saw blade. A latch arm is pivotally attached to the main body and rotatable about a pivot axis. A locking catch extends from the latch arm and retains the saw blade within the channel. A latch release extends from the latch arm. An actuator is provided to selectively engage the latch release and permit removal of the saw blade from the blade clamp assembly. The power saw tool may include a speed limiter housed within the handle grip to delimit rearward travel of the trigger switch, thereby restricting the speed of the motor. The power saw tool may also include a rotatable shoe assembly.
    • 一种电动锯工具,包括壳体,马达和往复轴。 刀片夹组件安装在往复轴上并适于夹紧锯片。 刀片夹具组件包括限定用于接合锯片的通道的主体。 闩锁臂可枢转地附接到主体并且可围绕枢转轴线旋转。 锁定钩从闩锁臂延伸并将锯片保持在通道内。 闩锁释放从闩锁臂延伸。 提供致动器以选择性地接合闩锁释放并且允许锯片从刀片夹具组件移除。 动力锯工具可以包括容纳在把手把手内的限速器,以限制触发开关的向后行进,从而限制电动机的速度。 动力锯工具还可以包括可旋转的鞋组件。

    • Apparatuses are provided for various tools that incorporate materials with a high coefficient of friction and a low coefficient of friction. The materials with a low coefficient of friction may be mounted on a tool and have a perpendicular movement to the tool. This perpendicular movement may be implemented with a spring mechanism. The materials with a high coefficient of friction may be mounted on the tool in a fixed position. The tool may be pressed against a surface, first engaging the materials with a low coefficient of friction. The tool may freely move across the surface while the materials with a low coefficient of friction maintain contact with the surface. As the tool is continually pressed to the surface, the materials with a high coefficient of friction subsequently make contact with the surface, thereby causing the lateral movement of the tool with respect to the surface to be restricted and stabilized. An example of the tool may be a spirit or carpenter level.
    • 为具有高摩擦系数和低摩擦系数的各种工具提供设备。 具有低摩擦系数的材料可以安装在工具上并且具有垂直于工具的运动。 该垂直运动可以用弹簧机构来实现。 具有高摩擦系数的材料可以以固定的位置安装在工具上。 工具可以被压靠在表面上,首先以低摩擦系数接合材料。 该工具可以自由地移动穿过表面,而具有低摩擦系数的材料保持与表面接触。 随着工具被不断地压向表面,具有高摩擦系数的材料随后与表面接触,从而导致工具相对于表面的横向移动被限制和稳定。 工具的一个例子可能是精神或木匠级别。
