摘要： Provided is a system and method for a hand tool with a plurality of quick release work heads. The hand tool includes a handle having a socket having a first longitudinal axis and an inner cavity extending rearward from an open distal end, the inner cavity having a first non-circular cross section transverse to the first longitudinal axis, the socket further having a quick release transverse to the first longitudinal axis, the quick release releasably disposing a locker transversely across a portion of the inner cavity. The hand tool also includes at least one work head having a second longitudinal axis and a shaft having a second non-circular cross section concentrically conforming to the first non-circular cross section of the inner cavity, the shaft further having a locking groove transverse to the second longitudinal axis and disposed to engage with the quick release locker when the shaft is disposed within the socket of the handle. An associated method of use is also provided.

摘要： The pneumatic hammer includes a hollow housing with handles for the user. A pneumatic driver is mounted inside the housing with an air tank for pressurized air. A reciprocating hammer assembly is slidably mounted inside the pneumatic driver and includes a hammer with a sharp hammer tip. The hammer is substantially hollow to efficiently capture released air from the air tank and drive the same. An alignment collar extends out of the housing and couples to the hammer assembly to set alignment of the hammer against an object to be impacted. The collar is normally locked in place. A control assembly is coupled to the housing, the pneumatic driver, and the collar to selectively release air driving the hammer out of the housing and unlock the collar for slidable movement into the housing.
摘要翻译：气动锤包括具有用于使用者的手柄的中空壳体。气动驱动器安装在壳体内部，带有用于加压空气的空气罐。往复锤组件可滑动地安装在气动驱动器的内部，并且包括具有尖锐的锤尖的锤。锤子基本上是中空的，以有效地从空气罐捕获释放的空气并驱动它们。对齐轴环延伸出壳体并且连接到锤组件以将锤对准待撞击的物体。衣领通常被锁定在适当位置。控制组件联接到壳体，气动驱动器和套环以选择性地释放将壳体驱动出壳体的空气，并且解锁套环以便可滑动地移动到壳体中。

摘要： A multifunctional tool with interchangeable tips includes a handle, a cover, at least one interchangeable tip and at least one removable securing means. The interchangeable tip is clamped at various points between the cover and the handle because the cavities of the handle and of the cover are not surfaces of revolution, whereas the diametrical recess of the interchangeable tip is a surface of revolution. The teeth of the handle engage the teeth of the cover, the parallel faces of said teeth meshing axially with respect to the tips preventing the cover from sliding off the handle. At least one removable securing means firmly secures the interchangeable tips and the cover to the handle.
摘要翻译：具有可互换尖端的多功能工具包括手柄，盖，至少一个可互换的尖端和至少一个可移除的固定装置。可互换的尖端被夹在盖和手柄之间的各个点处，因为手柄和盖的空腔不是旋转表面，而可互换尖端的直径凹槽是旋转表面。手柄的齿与盖的齿接合，所述齿的平行面相对于尖端轴向啮合，防止盖从手柄滑出。至少一个可拆卸的固定装置将可互换的尖端和盖子牢固地固定到手柄上。

摘要： An improved, versatile, lever bar which may be used as a crowbar, prybar, sledge hammer, pickaxe, wedge, etc. The lever bar has a long handle with a thick base plate chamfered at one end and secured perpendicular to the axis of the handle at one end thereof. A thick foot plate has a sharp end from which diverge edges defining an acute angle for entering under or behind boards to be pried. A massive, flat, triangular or trapezoidal anvil plate is secured to the base plate and handle. The base plate and anvil plate can serve as hammer heads while the tool is used as sledge hammer. The base plate and foot plate can serve as splitting wedges and as heads of a pickaxe.
