Abstract
An open-end wrench structure comprises a body having a handle portion and a driving portion, with the driving portion located at one end of the handle portion and including a driving slot. The bottom of the driving slot is provided with a first abutting surface and a second abutting surface connected to each other, forming a predetermined angle. A movable member is pivotally disposed within the driving slot and is rotatable between a first angle and a second angle. When the movable member rotates to the first angle, it abuts against the first abutting surface, and when it rotates to the second angle, it abuts against the second abutting surface.
