    摘要： The mechanism, used in a ratchet wrench, includes a body carrying an integral stud. A bore extends axially into both and a formed-spring actuator is reciprocally mounted therein. A transverse bore in the stud slidably holds a pin which is connected to the actuator. A socket is applied to the mechanism by pushing the socket against a camming surface on the pin to enable the socket to be snapped onto the pin without operating the actuator. The socket is removed by depressing the actuator. A ramp-like structure in the bore engages an offset part of the formed-spring actuator causing it to divert and move the pin to its release position. An elastomer push button is preferably attached to the actuator to sealingly protect the mechanism and also to provide a nice appearance.

    摘要翻译： 在棘轮扳手中使用的机构包括承载整体螺柱的主体。 孔被轴向延伸到两个中，并且成形弹簧致动器往复安装在其中。 螺柱中的横向孔可滑动地保持连接到致动器的销。 通过将插座压靠在销的凸轮表面上来将插座施加到机构，以使插座能够卡扣在销上而不操作致动器。 通过按下执行器来移除插座。 孔中的斜坡状结构接合成形弹簧致动器的偏移部分，使得其将销转移并移动到其释放位置。 弹性体按钮优选地附接到致动器以密封地保护机构并且还提供漂亮的外观。

    摘要： An electronic torque wrench has a hollow handle portion in which are disposed a DC motor mechanically coupled to the handle portion with a mass eccentrically mounted on its shaft, a control circuit for the motor and a battery for powering the motor and the control circuit. A strain sensor on the wrench produces an output signal when the torque applied to a workpiece equals or exceeds a predetermined torque level for causing the control circuit to actuate the motor to vibrate the handle portion and provide a tactile indication to the user.

    摘要： A self-locking pliers provides automatic jaw adjustment for gripping objects of different sizes. First and second pinsers-defining members each have a body portion, a jaw-defining portion and a handle portion, being joined by a bolt extending through a slot in one of the members in pivotal, mutually moveable relationship. The slot permits pivoting as well as sliding movement of the first member relative to the second member, and has along a jaw-proximate side teeth to be engaged by corresponding teeth of a locking pawl carried rotatably within the slot by a shank of the bolt. A jaw-remote side of the slotted opening provides a smooth surface for sliding engagement of a smooth reaction surface of the locking pawl opposite from its teeth. The locking pawl has on its jaw-proximate side a camming surface proximate to the locking teeth. A control arm is pivotally engaged at one end to the body portion of the second member. The body portion of the first member receives the other end of the control arm in slidably captive relationship, while a spring carried by the second member resiliently biases the control arm for movement about its pivoted end toward the jaws. The control arm initially causes the locking pawl reaction surface to bear against the jaw-remote side of the slot, so that squeezing the handles causes jaw-closing movement of the jaws until they close upon an object until contacted by the jaws. Such jaw contact the jaws causes the pawl to rotate within the slot for forcing its teeth into locking engagement with the rack for maintaining the jaws in locked, object-contacting relationship while handle pressure is maintained by the user. An interference-providing arrangement including a detent for the control arm provides controlled pawl engagement of the toothed rack and avoids "hanging up" the pawl or its inadvertent engagement.

    摘要翻译： 自锁钳为夹持不同尺寸的物件提供自动钳口调节。 第一和第二销子限定构件各自具有主体部分，夹爪限定部分和手柄部分，其以枢转的，可相互移动的关系通过延伸穿过其中一个构件中的狭槽的螺栓连接。 狭槽允许第一构件相对于第二构件的枢转以及滑动运动，并且沿着钳口邻近的侧齿啮合，以通过螺栓的柄部可旋转地承载在槽内的锁定爪的相应齿接合。 开槽开口的颚远侧提供了一个光滑的表面，用于与锁定棘爪的与其齿相对的光滑反应表面滑动接合。 锁定爪在其下颚附近具有靠近锁定齿的凸轮表面。 控制臂在一端枢转地接合到第二构件的主体部分。 第一构件的主体部分以可滑动的关系接收控制臂的另一端，而由第二构件承载的弹簧弹性地偏压控制臂以使其围绕其枢转端朝向夹爪移动。 控制臂最初使得锁定棘爪反作用表面抵靠槽的偏心的一侧，从而挤压手柄使夹爪闭合运动，直到它们靠近物体，直到被夹爪接触。 这样的夹爪接触夹爪使得棘爪在槽内旋转，以迫使其齿与齿条锁定接合，以将钳口保持在锁定的物体接触关系中，同时使用者保持手柄压力。 包括用于控制臂的制动器的干涉提供装置提供齿形齿条的受控棘爪接合，并避免“挂起”棘爪或其不经意的啮合。
