摘要： 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.

摘要： 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.

摘要： 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.

摘要： A unidirectional ratchet wrench structure has a wrench member, a pawl and a ratchet. The wrench member has an accepting space for accommodating the ratchet and an accepting space for accommodating the pawl. A toothed section of the pawl has a plurality of equiangular teeth and an irregular tooth. Since the irregular tooth is lower than the height of the equiangular teeth, the irregular teeth irregular tooth is capable of quickly disengaging from the equiangular teeth of the ratchet. The arc section and the toothed section have different arc measures and not push against the outer periphery of the ratchet at the same time, through the abutment of the pivoting point and the change of the center of gravity of the pawl when the wrench is rotated, the pawl is capable of producing a seesaw yaw movement to achieves the effect of quick engagement and disengagement.

摘要： A ratchet wrench comprising a housing, at least one gear supported within the housing, one of the at least one gear comprising a drive hole, a stationary handle extending from the housing, a dynamic handle hingedly extending from the housing such that, the dynamic handle is rotatable between at least one handle open position and a handle closed position, and at least one pawl, each of the at least one pawl adapted to slide between a pawl open position and a pawl closed position, one of the at least one pawl adapted to be in engagement with one of the at least one gear at a time. The dynamic handle disposed in operative communication with the at least one pawl such that, rotating the dynamic handle towards the handle closed position causes the at least one gear rotate in one direction and releasing the dynamic handle causes pawl to return to the pawl open position without causing the at least one gear to rotate in the opposite direction.

摘要： A socket includes two opposite ends and an axis extending between the ends. The socket further includes a small-diameter section in the vicinity of the first end, a large-diameter section in the vicinity of the second end, and a polygonal section between the small-diameter section and the large-diameter section. A circular bore extends in the small-diameter section along the axis. A non-circular bore extends in the polygonal section and the large-diameter section along the axis. Thus, an entire length of the socket and a length of the large-diameter section measured along the axis are rendered relatively small without reducing a depth of the non-circular bore.

摘要： A socket wrench with a reversible structure includes a rod, a sleeve, a first ratchet block and a second ratchet block. The rod has a columnar surface, and includes a first slot and a second slot. The first slot and the second slot are disposed on different positions along an axis direction of the rod. The sleeve is slidably sleeved on the rod, and includes an accommodating end and a driving end. The accommodating end includes a toothed segment which is protruded radially inward from an inner wall of the accommodating end. The first ratchet block is movably disposed in the first slot and includes a first ratchet portion. The second ratchet block is movably disposed in the second slot and includes a second ratchet portion. The toothed segment of the sleeve is selectively engaged with one of the first ratchet block and the second ratchet block.

摘要： A ratcheting driver comprises a driving mechanism combined between a handle and a working end for translating rotary motion from the handle to the working end. A switch engages the driving mechanism to switch the rotational direction of the working end between clockwise rotation and counter-clockwise rotation with an optional locked position that locks the working end. Two pairs of cooperating pawls are provided that are selectively engaged by the switch with one pawl in each of the two pairs of cooperating pawls selectively engaging one of a first ratchet gear and a second ratchet gear. Each pawl in the pair of cooperating pawls are positioned axially apart from each other in alignment with one of the first ratchet gear and the second ratchet gear.

摘要： A ratchet wrench may include a main body and a quick release member. The main body has a driving end, and a tool hole vertically penetrates therethrough. A housing concavely formed on an inner wall of the tool hole, and a teeth section is installed in the housing. A ratchet wheel is installed into the tool hole, and an outer periphery of the ratchet wheel is adapted to engage with the teeth section so as to enable the ratchet wheel and the tool hole to have synchronous rotation. A driving hole axially penetrates through the ratchet wheel. The quick release member has a magnetic ring, a pressing member, and a cover. The pressing member is adapted to move relative to the driving hole and the magnetic ring, such that a sleeve can be easily coupled in or detected from the driving hole so as to achieve the quick release effect.
