摘要： A method of making a wear and fatigue resistant component of a power tool (e.g., a clutch) includes providing a quantity of base steel and a quantity of alloying elements to be added to the base steel to form a desired alloyed grade of steel. The base steel and alloying elements are combined and melted to produce a molten alloyed steel (e.g., SAE 9310 or AISI M2). The molten alloyed steel is cast using a near-net-shape investment casting process to form a component of a power tool. An edge of the component is pre-radiused. and the component is case hardened after the edge of the component has been pre-radiused. In one implementation, the component is a clutch that has a lifespan of at least twice a lifespan of a second clutch that has not been pre-radiused prior to case hardening.

摘要： A portable pocket cutter employs a shaping assembly and a boring assembly, connected via a frame and coupling assembly, for constructing a pocket joint in a workpiece. The frame is at least partially supported upon a workpiece. The shaping assembly is pivotally connected with the frame and further connects with a first bit for shaping a recess in a planar surface of the workpiece. The boring assembly is also connected with the frame and further connects with a second bit for boring a through aperture into an edge of the workpiece, the edge being generally perpendicular to the planar surface.

摘要： A surgical instrument for assembling a spinal rod to a plurality of anchoring members includes first and second levers that are pivotally, and optionally removably, connected for rotation about a pivot axis. The first lever has a hollow guide tube forming a first handle section and a first distal end section, with a first longitudinal bore extending therethrough. The second lever has a second handle section, a second distal end section, and an intervening second intermediate section that interconnects the two in offset fashion. The second distal end section has a second longitudinal bore. The longitudinal bores accept bone anchor heads. Pivoting of the levers relative to each other about the pivot axis causes the bone anchors to move toward or away from each other. The first and second bores may be configured to mate with bone screw assemblies having extended tabs.

摘要： A power tool includes a motor assembly, a base assembly, and a clamp assembly coupled to the motor assembly or the base assembly to selectively provide a retention force to the other to removably couple the motor assembly and the base assembly. The clamp assembly includes a handle member, a fulcrum member, and a biasing lever member. The lever member includes a first portion and a second portion disposed on opposite sides of the fulcrum member. The handle member is coupled to the first portion, and the handle member is movable between an open and closed position. The handle member rotates the first and second portions of the biasing lever member about the fulcrum member when moving from the open to the closed position, causing the second portion of the lever member to provide the retention force.

摘要： The present invention provides a head valve assembly for a pneumatic fastener including a piston assembly reciprocated within a cylinder assembly for driving a fastener and a housing having an end cap for at least partially enclosing the head valve assembly. The head valve assembly includes a valve piston for causing supply pressure to be ported to the piston assembly for moving the piston assembly within the cylinder assembly from a non-actuated position to an actuated position for driving the fastener. Further, an inner cap is disposed within the end cap around the valve piston. The inner cap includes an inlet port for porting pressure to the valve piston. In addition, a main seal is coupled to the valve piston for sealing the cylinder assembly from supply pressure while pressure is ported to the valve piston by the inner cap for holding the piston assembly in the non-actuated position. The main seal seals pressure ported to the valve piston by the inner cap from supply pressure ported to the piston assembly.
