Abstract: A torque rod includes a main body; a transmission rod inserted to the main body and having a surrounding first groove exposed from the main body; an anti-release sleeve member mounted around the main body and having a second groove on an inner edge, with a setting space formed by the second groove and the first groove; a low-friction device in the setting space; a clutch device connected with the transmission rod and switchable between a transmission and a declutched statuses; a torque device providing a predetermined torque abutting against the clutch device, so the clutch device is in the transmission status, whereby the transmission rod transmits a torque through the clutch device to the main body. When the transmission rod bears a torque greater than the predetermined torque, the clutch device enters the declutched status, preventing the torque from being transmitted to the main body.

Abstract: A digitally displaying torque wrench with mechanical torque adjustment includes a main body, a wrenching device, a torque releasing device, a shaped elastic member, a torque adjusting device, and a torque sensing device. The torque adjusting device efficiently slides along a direction in parallel to an axis of the main body, so as to be operable by the user to adjust an axial position of a resting member of the torque adjusting device with respect to the shaped elastic member, thereby quickly adjusting the torque setting value of the wrench. Also, when the force transmission is stopped by the torque releasing device, the wrenching device provides a mechanical torque disengagement to notify the user of the force reaching the torque setting value.

Abstract: A digital-display torque wrench with mechanically adjustable torque includes a main body, a wrenching device, a torque-breaking device, a specially-shaped elastic member, a torque-adjusting device, a locking device, and a torque-sensing device. The torque-adjusting device has a sliding member, which changes a set torque value of the digital-display torque wrench when sliding along a direction parallel to an axis of the main body. The locking device assembled between the sliding member and the main body can be switched between a releasing position and a locking position. At the releasing position, a bearing portion of the sliding member can move with respect to the specially-shaped elastic member, and the torque-sensing device senses a locational change of the sliding member and displays the set torque value. At the locking position, the locking device exerts a force on the sliding member to increase frictional resistance between the sliding member and the main body.

Abstract: An electric quick action wrench with settable torque, which is operated in an electric mode or a manual mode, includes: a main body, a controller, a motor, a driving device, and a clutch device. The driving device is driven by the motor and combined with a fastener. The controller sets a threshold torque value. In the electric mode, when the fastener confronts a resistance larger than a clutch torque of the clutch device, the user is notified to switch to the manual mode through the notification of the clutch device. In the manual mode, when a manually output torque reaches the threshold torque value, the user is notified that the screwing operation has been finished by the notification of the clutch device. Thus, the safety of usage is achieved.

The torque shaft gradually bends form the first end toward the second end in accordance with an increase of the torque, so as to correspondingly display a corresponding torque value with different length positions of the torque shaft along the window.

Abstract: 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.
