摘要： A quick reciprocating wrench includes a main body, a claw, and an elastic device therebetween. The main body includes a first jaw opening having a pivot end and a block portion. The claw includes a second jaw opening having a pivotal combination portion and a retaining portion. The pivotal combination portion is pivotally connected with the pivot end, so the claw and the main body pivotally move against each other. The fastener is engaged in the first and the second jaw openings. Distance between the block portion and the neighboring force bearing face of the fastener decreases along a direction in opposite to the expansion direction of the claw and the block portion. The largest width of the distal end of the retaining portion is greater than the smallest distance between the block portion and the first force bearing face of the fastener.

摘要： An electric ratchet wrench includes a body receiving a driving device for driving a fastener. A first transmission device is connected to the driving device. A second transmission device is connected to a power device. A clutch device is mounted between the first and second transmission devices and is normally in a coupling state for driving the fastener. When the clutch device switches to the disengagement state due to a resistance larger than a torque outputted by the power device, the body can be manually driven to overcome the resistance, forcibly driving the fastener through the large-resistance position. The clutch device returns to the coupling state after the fastener passes the large-resistance position.

摘要： An electric socket ratchet wrench includes a body, a driving device rotatably mounted in the body, a pawl device coupled with the driving device, a power device providing a torque, a transmission device between the driving device and the power device, and a clutch device. The driving device includes a driving member having a non-circular hole for coupling with a fastener. The driving member includes an annular toothed portion coupled with the pawl device and an end toothed portion coupled with the transmission device. When a resistance smaller than the torque is encountered while the driving member is driving the fastener, the driving member continuously drives the fastener. When a large resistance larger than the torque is encountered at a position, the body is manually rotatable by a torque larger than the large resistance to forcibly drive the fastener through the position via the driving member.

摘要： A multifunctional torque wrench includes a main body, an operation member, and an indication device. The main body has a driving portion, a combination portion, and a twisting portion. The driving portion pivotally drives a fastener to rotate about an axis passing through the main body. The operation member is switchable between a first position and a second position with respect to the main body. The extension portion extends along a second axis. When the operation member is at the first position, the second axis is vertical to the first axis, allowing a user to turn the main body to generate the torque for driving a fastener. The indication device is disposed between the main body and the operation member for displaying the torque value. When the operation member is at the second position, the second axis is parallel to the first axis for storage.

摘要： A quick detachable and adjustable magnetic seat for sleeve includes a magnetic device and a detachable positioning device. The magnetic device includes a first end and a second end. The first end is magnetic. The detachable positioning device includes a connecting end slidably disposed on the second end of the magnetic device, such that the magnetic device axially slides against the detachable positioning device. The detachable positioning device further includes a resilient quick detach device disposed on one end of the detachable positioning device away from the connecting end, whereby the detachable positioning device is removably disposed in a sleeve. Therefore, when the sleeve is damaged or broken, the adjustable magnetic seat is efficiently removed from the sleeve and re-installed in a new sleeve replacement.

摘要： A ratchet wrench with tooth breakage resistance includes a body having a driving hole and a transmission hole intersecting with the driving hole. An inner periphery of the driving hole includes two adjoining portions on opposite sides of the transmission hole. An arcuate portion extends between the two adjoining portions. A tooth breakage preventing device is mounted in the arcuate portion and is configured to be in contact with one of first and second outer toothed sections of either of two first pawls to prevent tooth breakage between a toothed portion of the driving hole and the one of the first and second outer toothed sections of either of the two first pawls when the body is rotated to provide a ratcheting function for driving the fastener.

摘要： A torque wrench includes a driving device having a connecting rod pivotably connected to a body. The connecting rod is pivotably connected to a head of the driving device and is pivotable between first and second positions. The torque wrench has first and second lever arms corresponding to the first and second positions, respectively. A torque device is mounted to the body and presses against an abutting end of the connecting rod. An adjusting device is movably mounted to the body and is operatively connected to the torque device for setting an initial torque value. A measuring unit measures the initial torque value. An operating unit multiplies the initial torque value by a first or second correction coefficient corresponding to the first or second lever arm to obtain a corrected torque value. A display unit displays the corrected torque value.
