摘要： A wrench includes a rod, a retainer, and a casing for accommodating the retainer and allowing relative rotational movement between the casing and the retainer. The rod includes a driving portion on an end thereof for engaging with a fastener. The retainer has a central portion securely mounted to the rod to turn therewith. At least one engaging member is mounted in the casing and biased to selectively engage with one of plural retaining sections of the retainer, thereby exerting an engaging force between the engaging member and an associated retaining section of the retainer. When a rotational force applied to the casing is smaller than the engaging force, the retainer and the rod are turned to thereby turn the fastener. When the rotational force applied to the casing is greater than the engaging force, the casing slides while the retainer and the rod are not turned.

摘要： A screwdriver is disclosed, comprising a removable depth stop which selectably either, when equipped with the depth stop, allows noiseless shutoff or, with the depth stop removed, allows torque-dependent shutoff, without any chattering occurring when the machine continues to run. To this end, an adjustable torque-dependent release clutch is combined with an entrainment clutch of known type, which is additionally preceded by a disconnect clutch, a locking means being provided in order to hold a throwout ring, which forms one of the two elements of the disconnect clutch, in a predetermined position under load. In this way, noiseless operation is ensured after release, both when working with the depth stop and in the case of torque-dependent shutoff, with the depth stop removed.

摘要： A screwdriver of the type having a variable torque-limiting in-line drive with a handle having a cavity and a drive bit disposed in the cavity. Over-ride drive members are disposed in the cavity and a spring exerts a force on the drive members for transmitting only a maximum force to a bit in the screwdriver. Two adjustable controls are at a back end of the tool and they are used to apply a varying force to the spring and thus limit the amount of maximum torque to be transmitted.

摘要： A tappet screw adjuster having an outer sleeve, an inner shaft, a bearing block, a handle, and a rotary coupling disposed between the bearing block and the inner shaft. The rotary coupling is designed such that the bearing block and inner shaft rotate together when a load on the inner shaft is below a predetermined level and such that the bearing block and inner shaft do not rotate together when the load on the inner shaft exceeds the predetermined level. The rotary coupling includes a tension setting device, which is threadably secured to the bearing block, and a friction plate. The friction plate includes an annular projection that is received within a groove provided on the tension setting device.

摘要： A torque-limiting screwdriver includes a shank disposed within a handgrip. A rear end of the shank engages the handgrip to enable an axial force to be transmitted from the handgrip to the shank. A release mechanism is provided to transmit rotation from the handgrip to the shank. The release mechanism is axially movable relative to both the handgrip and the shank and is spring biased into rotation transmitting relationship with the shank, whereby the rotation transmitting force applied to the shank is substantially independent of the axial force applied from the handgrip to the shank.
