Abstract
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.
