Abstract: A wrench with a quick rotatable driving head includes a handle, a driving head and a quick-disengaging unit. The quick-disengaging unit is composed of a fixing member secured with the driving head, an operating member inserted through the handle and fitted around the fixing member, and a restraining element transversely provided between the fixing member and the operating member and the handle. The handle and the driving head can be separated by the quick-disengaging unit so that the driving head, with the quick-disengaging unit acting as a pivot, can quickly screw or unscrew a thread locking member, and the operating member can be restrictedly positioned on the fixing member by the restraining element, able to prevent the handle and the driving head from separating.

Abstract: An adjustable torque limiter that can be coupled between a high speed driver and the socket that rotates a mechanical fastener. When a preset torque level is reached, the torque limiter disengages the rotational drive force from the bit. The adjustability of the torque limitation is accomplished by varying the amount of spring force by which a thrust plate (coupled to the high speed driver) is forced against a set of steel balls residing in slots of a radial torque plate and in a set of paths formed in a concavity of an upper torque body (coupled to the driven socket engaging stud). When a certain preset torque is transmitted from the driver to the socket, the steel balls traverse outward along the separate arced ramp radial paths therein the upper torque body until the balls enter an annular race that allows the thrust plate to go into a disengaged or free wheel mode from the upper torque body.

Abstract: A tightening tool for tightening a fastener is disclosed which comprises a motor and a main shaft that engages with the fastener. A clutch is disposed between the motor and the main shaft so that the clutch rotates the main shaft by transmitting torque from the motor to the main shaft when a load acting on the main shaft is less than a predetermined value. The clutch shuts off torque transmission from the motor to the main shaft when the load acting on the main shaft reaches or exceeds the predetermined value. When in use, the current flowing to the motor and rotation angle of the main shaft of the motor are detected. The detected current and rotation angle are used to determine whether the tightening torque of the fastener is normal.
