摘要： An expansion dowel consists of a sleeve, a tie rod extending through the sleeve with an end support on one end of the tie rod and an expanding body on the other end. The end support can be a bolt head or a nut. By applying torque to the end support the expanding body can be pulled into the sleeve causing it to expand. A jacket laterally encloses the end support in form-locking engagement. The jacket is formed of a destructible material, such as a plastic, which is demolished when a predetermined torque is applied through the jacket to the end support signalling that a certain anchoring force has been achieved.
摘要翻译：膨胀销由套筒，延伸穿过套筒的拉杆和拉杆的一端上的端部支撑件和另一端的膨胀体构成。端部支撑件可以是螺栓头或螺母。通过向端部支撑件施加扭矩，膨胀体可以被拉入套筒中，使其膨胀。护套横向围绕端部支撑件以形状锁定接合方式包围。护套由诸如塑料的可破坏材料形成，当通过护套将预定扭矩施加到端部支撑件时，该塑料被拆除，表明已经实现了一定的锚定力。

摘要： In a drill chuck for securing the shank of a tool in a hand-held device, clamping jaws are mounted in a chuck member and bear radially outwardly against the conically shaped surface in a first sleeve into which the tool shank is inserted. A second sleeve is connected to the first sleeve and is threaded engagement with the chuck member. A locking or third sleeve is located about the first and second sleeves. The third sleeve is axially displaceable between a first position and a second position. In the first position the third sleeve engages the first and second sleeves so that the second sleeve cannot be rotated relative to the first sleeve or the chuck member and the tool shank can be locked by the clamping jaws. When the third sleeve is displaced into the second position, the second sleeve is released and can be rotated relative to the chuck member for axially displacing the first sleeve relative to the chuck member and adjusting the radial position of the clamping jaws.
摘要翻译：在用于将工具的柄固定在手持装置中的钻夹头中，夹爪被安装在卡盘构件中，并且在工具柄插入其中的第一套筒中径向向外抵靠锥形表面承受。第二套筒连接到第一套筒并且与卡盘构件螺纹接合。锁定或第三套筒围绕第一和第二套筒定位。第三套筒可在第一位置和第二位置之间轴向移动。在第一位置中，第三套筒接合第一和第二套筒，使得第二套筒不能相对于第一套筒或卡盘构件旋转，并且工具柄可被夹爪锁住。当第三套筒移动到第二位置时，第二套筒被释放并且可以相对于卡盘构件旋转，用于相对于卡盘构件轴向移动第一套筒并调节夹爪的径向位置。

摘要： A drilling tool consists of a drill and a tubular shaped receiving part fitted onto the trailing end of the drill. The outer surface of the receiving part is shaped to fit into the chuck or retainer of a drilling device which rotates the drill. The inner surface of the receiving part and the juxtaposed surface on the trailing end of the drill are in locking engagement, however, under certain torque conditions the locking engagement will be released so that the receiving part can rotate relative to the drill. Preferably, the locking engagement is established by deflectable projections formed on at least one of the receiving part and the drill which seat into recesses formed on the juxtaposed surface of the other. Passageways are provided between the trailing end of the drill and the receiving part.
摘要翻译：钻具由钻头和安装在钻头尾端上的管状接收部件组成。接收部分的外表面被成形为装配在旋转钻头的钻孔装置的卡盘或保持器中。接收部分的内表面和钻头后端的并置表面处于锁定接合状态，然而，在某些扭矩条件下，锁定接合将被释放，使得接收部件可相对于钻头旋转。优选地，锁定接合由形成在接收部分和钻头中的至少一个上的可偏转突起形成，所述可弯曲突起位于形成在另一个的并置表面上的凹部中。通道设置在钻头的后端和接收部分之间。
