摘要： The invention is directed to a foldable, portable workbench having a work table and a support structure for supporting the work table. The support structure includes a pair of mutually spaced leg assemblies and each of these leg assemblies, in turn, includes a pair of legs pivotally connected at one end thereof to the work table. Articulated linkages pivotally interconnect, respectively, the two legs of each pair of legs to each other and at least one of the legs to the work table. The articulating linkages are connected so that the work table and leg structures are stacked in juxtaposition to each other when the workbench is in its folded position and, so that the other ends of the leg structures are spread apart from each other with the work table substantially transverse to the leg structures when the workbench is in the erected position.

摘要： The invention is directed to a clamp for holding a workpiece to a work surface having an aperture formed therein. The clamp includes the main support arm having one end portion adapted for insertion into the aperture in the work surface. A clamping arm is pivotally connected to the main support arm above the above-mentioned end portion and the clamping arm defines a clamping surface for engaging the workpiece placed on the work surface. A first lever arm is pivotally connected to the main support arm and a second lever arm has one end pivotally connected to the first lever arm and another end pivotally connected to the clamping arm. Suitable structure is provided for applying a force to the pivot mutually connecting the first and second lever arms to cause the lever arms to transmit the respective forces to the main support arm and the clamping arm causing, in turn, the main support and the clamping arm to rotate with respect to each other so that the main support arm tightly engages the wall defining the aperture in the work surface and so that the clamping arm tightly engages the workpiece. The clamp also can be adapted to hold a workpiece to a workbench having no aperture therein. A clamping arrangement includes a member defining a work surface and having at least one aperture formed therein and the clamp. The clamp and member tightly hold the workpiece.
摘要翻译：本发明涉及用于将工件保持在其上形成有孔的工作表面的夹具。夹具包括主支撑臂，其具有适于插入工作表面中的孔中的一个端部。夹持臂在上述端部上方枢转地连接到主支撑臂，并且夹紧臂限定用于接合放置在工作表面上的工件的夹紧表面。第一杠杆臂枢转地连接到主支撑臂，并且第二杠杆臂的一端枢转地连接到第一杠杆臂，另一端枢转地连接到夹紧臂。提供合适的结构，用于向相互连接第一和第二杠杆臂的枢轴施加力，以使杠杆臂将相应的力传递到主支撑臂和夹紧臂，从而使主支撑件和夹紧臂以相对于彼此旋转，使得主支撑臂紧密地接合限定工作表面中的孔的壁，并且使得夹紧臂紧紧地接合工件。夹具还可以适于将工件保持在其中没有孔的工作台。夹紧装置包括限定工作表面并且具有形成在其中的至少一个孔和构件的构件。夹子和构件紧紧夹住工件。

摘要： A portable power tool or appliance, such as a cordless grass shear, may be slidably received within a unitary stirrup. A flexible flap on the stirrup carries a detent button that is automatically snapped into a screw-hole on the clam-shell power tool housing, as the power tool is fully seated within the stirrup. The flap may be flexed manually to release the detent button, thereby facilitating quick disengagement between the power tool and the stirrup. The stirrup carries ground-engaging wheels to facilitate manual movement and guidance of the power tool during its stand-up operation. An extension handle in the form of a tubular wand is secured to the stirrup and extends upwardly therefrom. A top handle with a switch is provided on the end of the wand. An electrical cable is connected to the switch, extends downwardly therefrom within the wand, and exits from the stirrup above the power tool. The end of the cable carries a plug adapted to be received within a receptacle on the power tool. The receptacle has spaced contacts formed as a continuation of the contacts of the tool switch. This provides a parallel connection, bypassing the tool switch and, at relatively low cost, facilitating manual control by the switch on the top handle.
摘要翻译：便携式电动工具或器具，例如无绳草剪，可以可滑动地接收在单一马镫内。马镫上的柔性翼片带有一个定位按钮，自动锁定在蛤壳式电动工具外壳上的螺孔中，因为电动工具完全固定在马镫内。可以手动弯曲翼片以释放制动按钮，从而有助于电动工具和马镫之间的快速分离。马镫带有接地轮，以便在其立式操作期间手动移动和引导电动工具。管状棒形式的延伸手柄固定在马镫上并从其向上延伸。在魔杖的末端提供带有开关的顶部手柄。一根电缆连接到开关上，从该杆向下延伸，并从电动工具上方的马镫上出来。电缆的端部承载适于容纳在电动工具上的插座内的插头。插座具有形成为工具开关的触点的延续部的隔开的触点。这提供了并联连接，绕过工具开关，并且以相对较低的成本，便于手柄上的手柄控制。

摘要： An improved shifter mechanism for the transmission of a power tool in which the operating lever can be located to either side of the transmission housing. The operating rod has a flat which operates one end of a pivoted shift member, the other end of which moves a clutch member to engage or disengage a rotation clutch. The shifter provides positive action, a long throw, and permits operation in either direction. The clutch itself includes an improved lubrication feature and improved mounting of the fixed clutch member to the armature shaft.

摘要： A dust cap particularly for use with an overhead rotary hammer. The dust collector is a cup-like member with a bellows side wall, integrally formed in one piece. It has a thickened neck to fit on the tool shank below the chuck, thereby encompassing the chuck and the lower end of the anchor. Dust is efficiently caught in that the bulk of the dust passes through the anchor and chuck, and then directly into the dust collector cup, plus most of the dust outside the anchor is also caught as it falls around the anchor. The bellows side wall facilitates changing tools and removing anchor ends.
摘要翻译：专门用于高架旋转锤的防尘盖。集尘器是具有波纹管侧壁的杯状构件，整体形成为一体。它具有加厚的颈部，以适合卡盘下方的工具柄，从而包围卡盘和锚的下端。灰尘被有效地捕获，因为大部分的灰尘通过锚和卡盘，然后直接进入集尘杯，加上主锚外部的大部分灰尘也会在锚固件周围被捕获。波纹管侧壁有助于更换工具并移除锚固端。
