摘要： The present invention relates an impact tool (10) with a twin lobed anvil (20), and the separate anvil, timing shaft (40) and mating dog hammer (60). The impact transmission is configured in such a way so as to maintain contact between the anvil (20) and dog hammer (40). As a result, the components of the present invention provide a harder blow to the anvil of an impact tool due to a larger strike surface area, provide greater torque due to increased mass at engagement, and increase the durability of the impact tool.
摘要翻译：本发明涉及一种具有双叶片砧座（20）的冲击工具（10）和分离的砧座，正时轴（40）和配合耙锤（60）。冲击传动装置以这样的方式配置，以便保持砧座（20）和槌锤（40）之间的接触。结果，本发明的部件由于较大的冲击表面面积而对冲击工具的砧座造成更大的冲击，由于在接合时的质量增加而提供更大的扭矩，并且增加了冲击工具的耐久性。

摘要： A throttle air inlet for a pneumatic tool which includes a swivel air inlet bushing for rotatably attaching the pneumatic tool to a pressurized air supply hose. The air inlet bushing includes a first groove, formed on an exterior surface of the bushing, which rotatably mates with a pin-roll inserted in the handle of the pneumatic tool. This configuration allows the air inlet bushing to rotate about its longitudinal axis within the handle of the pneumatic tool. When the air supply hose is attached to the exterior end of the air inlet bushing, the pneumatic tool can be swiveled independently of the air supply hose.
摘要翻译：一种用于气动工具的节流空气入口，其包括用于将气动工具可旋转地附接到加压空气供应软管的旋转空气入口衬套。空气入口衬套包括形成在衬套的外表面上的第一凹槽，其与插入气动工具的手柄中的销辊可旋转地配合。这种构造允许空气入口衬套围绕其纵向轴线在气动工具的手柄内旋转。当供气软管连接到进气套管的外端时，气动工具可独立于供气软管旋转。

摘要： An elastic ring for maintaining a pin (26) in a hole formed in a socket and work drive shaft (10) of a rotary tool. The ring has integral fingers (24) which project into the ends of the hole so that the pin (26) cannot dislodge the ring by centrifugal force when the tool is operating at high speed. Several variations of the ring include weighted areas at portions of the ring midway between the fingers (24), which areas counterbalance centrifugal force on the ring to supplement holding force of the fingers upon the pin (26).

摘要： A vibration-reduced impact tool (10) is disclosed wherein an elastomeric vibration isolator (23) is fixedly attached within the tool housing (11) and functions to absorb the vibration typically transmitted from the handle (13) to the operator. The isolator (23) is mounted between the cylinder assembly (12) and the handle (13). As the tool is operated, a piston (22) within the cylinder assembly (12) is driven forward where it impacts with a tool accessory. The impact causes the piston (22) and cylinder assembly (12) to slide rearward in the tool housing (11), toward the handle (13). The elastomeric isolator (23) absorbs the rearward movement of the cylinder assembly (12) and thereby eliminates much of the vibration normally transmitted from the cylinder assembly (12) to the handle (13) and in turn, to the operator.

摘要： The present invention relates generally to pneumatic ratcheting mechanisms (10) and in particular to a device to aid in shank spindle retainment during ratchet resetting. According to the present invention, at least one recess (66) is provided in the shank spindle (60) of a ratchet head to receive a spring (64) therein. The end of the spring is compressed against an interior surface of the ratchet head (30) to frictionally retain the shank spindle (60) and pawl (50) of the ratchet during the resetting stroke of the ratchet yoke.
