An alerting structure of an electronic torque tool includes a tool body and an electronic module. The electronic module includes a sensing unit, a processing unit, and at least one display unit. The sensing unit senses an operational value of the tool body. The processing unit sends the operational value sensed by the sensing unit to the display unit. The display unit has at least one display block. When the operational value sensed by the sensing unit reaches a predetermined value, the processing unit generates a rotation signal in order for the contents displayed by the display block of the display unit to rotate back and forth through a predetermined angle and thereby produce a conspicuous alerting effect.

A ratchet wrench is provided, including a main body, a ratchet mechanism and a switch mechanism. The ratchet mechanism includes a ratchet and a pawl unit. The switch mechanism includes a pushing member and a moving member, the pushing member is disposed on the moving member, the pushing member is optionally connected to the pawl unit, and the moving member is movably disposed on the main body.

A reversible ratchet wrench includes a moveable pawl connected to a handle via a linkage such that the pawl cannot become disengaged from the hand during operation of the wrench. The handle is pivotally attached to housing forming a portion of a head of the wrench, where pivoting of the handle between a first position and a second position switches a position of a pawl between a first position and a second position to thereby change an operating direction of the wrench. A distance of movement of a proximal end of the handle, opposite a head of the wrench, during switching is confined to a limited range by elongating the wrench head and extending a distance between a connection point of the handle to the pawl and the pivotal connection of the handle to the housing.

The combined battery jumper cable with wrench is configured for use with a vehicle. The combined battery jumper cable with wrench forms an electric termination that attaches a cable to a terminal post of the vehicle battery. The combined battery jumper cable with wrench forms a ratchet that is used to attach an electrical terminal of the vehicle to the terminal post of the vehicle battery. The combined battery jumper cable with wrench includes a working head, a transfer mount, and a motive structure. The transfer mount attaches the motive structure to the working head. The working head is the working element of the tool. The motive structure transfer externally provided energy to the working head through the transfer mount. The motive structure removably attaches to the transfer mount.

A tie-down apparatus includes a frame, a reel, a coils spring and a strap-replacing tool. The reel is supported on the frame. The coil spring includes an end connected to the frame and another end connected to the reel. The strap-replacing tool for gear includes a gear and a pawl. The gear is connected to the reel at an end and formed with teeth on a periphery. The is pawl engaged with the teeth of the gear so that the pawl prevents the gear from rotation in a first sense of direction and that the pawl allows the gear to spin in a second sense of direction opposite to the first sense of direction. The pawl keeps the gear in position against torque provided from the coil spring via the reel that tends to rotate the gear in the first sense of direction.

The present specification relates to a bolt tensioning tool adapted to tension a bolt protruding from a workpiece, and comprising a bolt receiving element (5) adapted to be screwed onto the bolt, a nut socket (10) adapted to receive a nut, an axle (3) adapted to exert an axial force on the bolt receiving element, a threaded sleeve (6) arranged to engage the axle and having an internal thread (6a) adapted to cooperate with an external thread (3a) of the axle (3) such that a relative rotational movement there between results in a relative axial displacement between the axle and the threaded sleeve, a supporting sleeve (2) coupled to the threaded sleeve and adapted to selectively bear against the workpiece and a coupling (9) adapted to connect the nut socket and the supporting sleeve, the coupling is a coupling allowing a limited relative movement between the socket and the sleeve.

A rapid ratchet wrench capable of being used in one hand comprises a handle, a wrench head, pawls, and a tensioner head, wherein the wrench head is arranged at the top end of the handle, and a left pawl and a right pawl are arranged at positions close to the handle in a sleeve hole. The tensioner head is mounted at the top end of a control mechanism, and a propelling head is arranged at the tail end of the control mechanism; and the adjacent sides of the left pawl and the right pawl are respectively provided with a touch head in a staggered manner, the tensioner head can respectively touch one of the touch heads and ejects the corresponding pawl to make same open outwards, and the other touch head is in the working position.

A flex-head tool includes a first portion pivotally coupled to a second portion. A pivot mechanism is engaged with the first and the second portions. The pivot mechanism is movable between a first position in which the first portion is fixedly positioned with respect to the second portion, and a second position in which the first portion is pivotal with relative to the second portion. The pivot mechanism includes a toothed first engaging portion engageable with teeth of pivot holes of the first and the second portions simultaneously and not simultaneously selectively and a second engaging portion connected with a pivot hole and in surface-to-surface contact.

A ratchet tool having a head having a first cavity is adapted to receive a cover plate and a second cavity. An aperture extends between the first cavity and the second cavity. Disposed in the first cavity is a ratchet gear and a pawl. A selector switch disposed in the second cavity and moves the pawl between a first position and a second position. A retaining clip retains the selector switch in the second cavity. The retaining clip extends into the first cavity. The pawl includes a first extended portion and a second extended portion extending from a lower end of the pawl. At least a portion of the retaining clip is disposed between the first extended portion and the second extended portion. The first extended portion and the second extended portion contact the lower surface of the first cavity. An upper end of the pawl contacts the cover plate.

A screw driving tool including a torque output element which defines an axis and is mounted in a housing, a torque transmission section with a plurality of depressions, and a torque transmission element, which is pretensioned by the force of a force accumulator and engages into at least one of the depressions, for coupling the torque transmission section to the housing so as to transmit a torque, the torque-transmitting coupling being released when the torque transmission element leaves the depression in an edge-controlled manner against the force of the force accumulator, which can be adjusted by an adjustment device, when a limit torque is exceeded. In order to develop the tool in an advantageous manner in terms of application, a switchover element is proposed which can be moved from a release position into a blocking position and which allows the torque transmission element to leave the depression in the release position but blocks the torque transmission element in the blocking position.
