A reciprocating wrench for quick combining fastener includes a main body, a claw, and an elastic positioning device therebetween. The main body includes a concavely-shaped first jaw opening, which has a pivot end at an end thereof. The claw includes a concavely-shaped second jaw opening, which has a pivotal combination portion at an end thereof. The pivotal combination portion is pivotally connected with the pivot end, such that the claw and the main body pivotally move with respect to each other. The elastic positioning device allows the claw to optionally rotate toward a closing direction or remain in the opening status. Therefore, the claw is able to remain in the opening status for combining the fastener.

A quick reciprocating wrench includes a main body, a claw, and an elastic device therebetween. The main body includes a first jaw opening having a pivot end and a block portion. The claw includes a second jaw opening having a pivotal combination portion and a retaining portion. The pivotal combination portion is pivotally connected with the pivot end, so the claw and the main body pivotally move against each other. The fastener is engaged in the first and the second jaw openings. Distance between the block portion and the neighboring force bearing face of the fastener decreases along a direction in opposite to the expansion direction of the claw and the block portion. The largest width of the distal end of the retaining portion is greater than the smallest distance between the block portion and the first force bearing face of the fastener.

A faucet actuator torque increasing system and method for increasing torque applied to an actuator includes a grip. The grip has a perimeter wall with a continuous convexly arcuate shape. A coupler is removably mounted on the perimeter wall of the grip. The coupler includes a first segment and a second segment which are pivotably coupled to each other via a connector. The first and second segments move between a closed condition engaging the grip and an open condition for disengaging the grip. Each of the first and second segments has an interior surface. The interior surfaces abut the grip in the closed condition. A locking member releasably locks the coupler in the closed condition. A handle is integrally attached to and extends away from the coupler. A stop is attached to the coupler to abut against the grip when in the closed condition.

A pipe wrench includes a fixed jaw with alternatively located first recesses and first driving faces defined in the inner side thereof. A pivotal member is pivotably connected to the fixed jaw and a resilient member is biased between the fixed jaw and the pivotal member. The pivotal member has alternatively located third recesses and second driving faces. A hexagonal space is defined between the first and second driving faces. The end portion of the pivotal member is inserted into a second recess defined in the inner side of the fixed jaw. The object is clamped in the hexagonal space, and the pivotal member can be pivoted away from the fixed jaw. The pipe wrench is able to quickly clamp and dismounted from the object.
