  • Patent number: 10926382
    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.

  • Patent number: 8359892
    Abstract: A rebar bending device for bending rebar. The device features a base plate and a rotator plate pivotally attached to the top of the base plate. A top plate is attached atop the rotator plate. A first pin extends from the base plate through the rotator plate and through the top plate. The rotator plate can rotate about the first pin with respect to the base plate and top plate. An arc-shaped slots are disposed in the top plate, which is adapted to receive a dial pin that is anchored to the rotator plate. A dial is marked atop the top plate (the second marker plate). A second pin is disposed on the top of the top plate near the first pin and a third pin is disposed on the top of the rotator plate.

  • Publication number: 20130014616
    Abstract: The invention relates to a combination (1) of control cabinet keys (2), individual keys being situated in the same plane but extending at a fixed angle (x) relative to one another and connected via a common center part (4, 5). Due to the fixed connection between the keys, during handling, a torque may be applied to a key (2) that is used.

  • Publication number: 20120318106
    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.

  • Publication number: 20120297932
    Abstract: A hand-held powered wrench includes a primary handle and a secondary handle. A motor is mounted on a primary handle. The secondary handle provides a second hand grip position which is significantly displaced from the primary handle axis, and includes a motor control for starting and stopping the motor. By having the significant displacement of the motor controlling second hand grip position, the operator naturally chooses a better stance and naturally dissociates the motor control hand from the torque sustaining hand in operation of the power wrench. The hand-held powered wrench can be used such as for safely exercising fire hydrant valves.

    Abstract: A socket extension and related methods of utilizing a socket extension that improves upon conventional designs through the use of a shaped body allowing the socket extension to be manipulated with an appropriate tool at any point along the shaped body. Through the use of the shaped body, a user is provided multiple engagement points such that interference due to the proximity of other structures or other accessibility issues can be overcome. In addition, the shaped body presents the opportunity to utilize a plurality of tools on the same socket extension when additional force/torque is necessary to loosen and/or tighten a bolt.

  • Patent number: 8297154
    Abstract: A combination wrench includes a shank, a first driving member mounted on a first end of the shank, and a second driving member mounted on a second end of the shank. The shank has different cross-sectional profiles and areas from the first driving member to the second driving member so that the shank has different thickness from the first driving member to the second driving member so as to correspond to different forces. Thus, the mediate portion of the shank has a uniform thickness and has greater strength and torque so as to withstand a larger force so that when a stress is concentrated on the mediate portion of the shank, the mediate portion of the shank can tolerate the stress, thereby preventing the shank from being deformed or broken due to an excessive force.
