Abstract
A ratchet wrench capable of rotating quickly and driving rotation includes a handle, a rotary head, a positioning mechanism, and a sleeve. The handle includes an arm and a bar body. The bar body includes an accommodating slot; the arm includes a through hole. The rotary head is connected to the arm and includes recess portions. The positioning mechanism includes a positioning element, a resilient body, and a block element. The resilient body receives the positioning element and is received in the through hole, the positioning element is correspondingly disposed in any of the recess portions, and the block element is connected to the positioning element. The sleeve receives the bar body and operably drives the block element to slide in the accommodating slot, so that the positioning element is positioned and selectively engaged with any recess portion.
