Abstract
A fast rotation structure of wrench and wrench thereof are provided. The rotation structure includes a seat connected with the ratchet head of the wrench. The seat has a first pivot connection portion which is pivotally connected with a second pivot connection portion of a rocker arm, such that the rocker arm sways between a folding position and a driving position. At the folding position, the rocker arm is combined with the seat. At the driving position, the rocker arm protrudes from one side of the seat, so as to drive the seat to rotate from an outer side of the seat. Therefore, the ratchet head is able to efficiently rotate.
