A torque structure includes a first body, a second body, a first elastic member, a third body, and a limit unit. The second body is provided with a second receiving chamber, a first pivot portion, at least one first positioning portion and at least one second positioning portion. The first elastic member is received in the second receiving chamber. The third body is provided with a drive portion, a pivot seat, a second pivot portion, and a first limit portion. The limit unit is assembled with the second body and the third body and rotated between a disengaging position where the third body is unlocked from the second body and has a torque slip function relative to the second body, and a engaging position where the third body is locked by the second body and does not have a torque slip function.

A toggler structure for a ratchet wrench includes an elongated toggler arranged between a locking member and a direction switch member of the ratchet wrench. The rear side of the toggler includes at least two connecting portions. At least two elastic elements are arranged between the connecting portions of the direction switch member and the toggler in order to provide an elastic force to push the toggler to abut against the locking member. The elongated toggler can be applied to a ratchet structure of a greater thickness in order to increase the structural strength and operational torque of the ratchet wrench. Furthermore, the elastic elements can provide a uniform elastic force in the length direction of the toggler, thereby allowing the locking member to engage with the ratchet structure properly.

An electronic torque wrench with a battery receptacle adapted to receive either a unitary battery pack or a battery tray containing separate batteries inside. The battery tray can receive conventional batteries such as AA, AAA, C, D or 9-volt sized batteries, and the battery tray and unitary battery can be constructed of a similar geometry to fit within the battery receptacle. The battery tray and unitary pack can include an outwardly-extending protrusion that is received within a groove of the battery receptacle. In this manner, only the specially-designed battery tray and pack are capable of coupling with the receptacle.

A torque wrench (100, 400) may include a body (410), a force detector (420) operably coupled to the body and configured to detect a bending force applied to the body, and a user interface (140) operably coupled to the body and the force detector. The user interface may be configured to include a setting mode in which a variable feature of the torque wrench is adjustable. The user interface may be further configured to, when in the setting mode, adjust the variable feature based on the bending force applied to the body and detected by the force detector.

A tool with a drive lug having groove formed on the drive lug to promote failure of the drive lug before internal component failure. The groove has a predetermined diameter and is formed on the drive lug or ratchet square to cause failure of the drive lug, due to a torsional ductile fracture, before any internal component failure of the tool, such as, for example, gear and/or pawl failure in a ratchet wrench.

A ratchet tool provided, including: a driver body, including a handle and a working rod connected with the handle, at least one of the handle and the working rod being integrally formed with a first blocking structure; at least one sleeve member, being disposed around and unidirectionally rotatable about the driver body, integrally formed with a second blocking structure, at least one of the first and second blocking structures being configured as a ratcheting structure, the second blocking structure being releasably stuck with the first blocking structure in a rotation direction; wherein when there is a relative torque greater than a predetermined torque between the at least one sleeve member and the driver body, at least one of the first blocking structure and second the blocking structures deforms and the second blocking structure is slidable over the first blocking structure in the rotation direction.

A powered ratchet tool includes a housing, an output member having a toothed surface, and a drive mechanism for driving the output member. The drive mechanism includes a yoke in which the output member is arranged. A first pawl is in the yoke and is biased toward the toothed surface of the output member and a second pawl is in the yoke and is biased toward the toothed surface of the output member. A selection ring having a circumferential wall is arranged between the yoke and the toothed surface of the output member. The circumferential wall has a first window and a second window and the selection ring is moveable between a first position and a second position.

A structure for mounting a cover plate in a head portion of a wrench is disclosed. An end surface of the head portion is concavely provided with a receiving chamber. The head portion is also concavely provided with a recess at the opening of the receiving chamber. The cover plate is mounted in the recess to close the receiving chamber, and the cover plate is fixed in the recess by the peripheral wall of the recess itself In other words, the cover plate is mounted in the head portion of the wrench without using any connecting element and is fixed by the head portion of the wrench itself. The cover plate, once fixed, is kept from coming off so that the components mounted in the receiving chamber of the head portion will not fall out.

A torque structure includes a first body, a second body, a first elastic member, a third body, and a limit unit. The second body is provided with a second receiving chamber, a first pivot portion, at least one first positioning portion and at least one second positioning portion. The first elastic member is received in the second receiving chamber. The third body is provided with a drive portion, a pivot seat, a second pivot portion, and a first limit portion. The limit unit is assembled with the second body and the third body and rotated between a disengaging position where the third body is unlocked from the second body and has a torque slip function relative to the second body, and a engaging position where the third body is locked by the second body and does not have a torque slip function.

A first base station receives from a second base station, a handover request message comprising traffic pattern parameters of a wireless device. The traffic pattern parameters comprise a first traffic periodicity, a first timing offset, and a first message size. A handover request acknowledge message indicating at least one periodic resource configuration parameter determined based on the first traffic periodicity is sent to the second base station. A random access preamble associated with a handover of the wireless device is received from the wireless device. The first base station determines a resource block assignment based on the first message size. A control command is transmitted to the wireless device. The control command indicates: activation of radio resources associated with the at least one periodic resource configuration parameter; and the resource block assignment.
