A wrench includes a main body with a fixed jaw and a sliding slot, a jaw portion, and a handle with a toggle element. The jaw portion has a movable jaw wherein a bottom of the movable jaw forms a sliding portion forming a restricting recess. A contact surface between a bottom of the sliding portion and a bottom of the sliding slot defines an interface wherein an extension of the interface traverses the restricting recess. When the handle is at a driving position, the toggle element abuts against the sliding portion, and the extension of the interface traverses the toggle element. When the handle is at a release position, the movable jaw is able to move away from the fixed jaw. Thereby, the pulling force from a user can be fully transmitted to the movable jaw and the fixed jaw. |
