Abstract

The invention provides a ratchet spanner comprising a grip handle, a head portion, a movable jaw and a bias pressing device. The head portion is formed on one end of the grip handle and comprises at least one fixed jaw, a sliding chute and a containing hole, wherein the sliding chute is communicated with the containing hole. The movable jaw comprises a clamping portion, a connecting portion and a containing groove. The connecting portion is arranged on one end of the clamping portion far away from the fixed jaw and is slidingly arranged inside the sliding chute. The containing groove is arranged in the connecting portion and is communicated with the containing hole. The bias pressing device comprises a limiting element and a bias pressing element. The limiting element is connected with the containing hole. The bias pressing element is contained in the containing hole and the containing groove. Two opposite ends of the bias pressing element respectively press against the limiting element and the containing groove.

Description

technical field [0001] The invention relates to a wrench, especially a wrench with ratcheting function. Background technique [0002] A wrench is a hand tool that uses the principle of leverage to turn bolts, nuts, and other fasteners that are difficult to turn by hand. The wrench is usually provided with openings at either end or both ends of the handle to hold the fastener, and the user can turn the fastener by applying an external force on the other end of the handle along the direction of rotation. There are quite a lot of types of wrenches, one of which is adjustable wrench, and the frequency of use of adjustable wrench is quite high, because it can freely adjust the size of the opening to be suitable for clamping fasteners of various sizes, without the need Various types of open-end wrenches are used for fasteners. For users, only an adjustable wrench can replace multiple open-end wrenches of a single size, which brings great convenience and applicability. [0003] G...
