Abstract

The present invention relates to a pairing method and structure of dual-head ratchet wrench with special D-head locking, in which the ratchets of the two ends of a ratchet wrench are respectively provided with a driving head having the dimension in compliance with a special D-head having the dimension of 10, 13, or 19 mm in metric system, or 3/8, 1/2, or 3/4 inch in imperial system, and the driving end at the bottom part of the driving head can be 3/8, 1/2, or 3/4 inch respectively. The pairing method is that the driving heads of the two ends of the wrench can be any two sets of dimensions aforementioned matching up with the dimension of the square column or hexagonal column of the D-head, that is, two ends of the same wrench respectively have a driving head with different dimension. Even the two ends of each wrench can be different in dimension, the ratchet wrench of special dimension can form a D-head wrench or a H-stem wrench when matching up with D-head of different dimensions, and has two or above dimensions, so as to facilitate the dual head ratchet wrench to be the driver for workpiece with different dimensions by matching up with socket of relative dimension or extension bar structure of other dimension.
