  • Publication number: 20190099865
    Abstract: The ratchet wrench has a switching button including a switching portion outside and a control portion in the wrench. The top face of the control portion is formed with an insertion groove, and a T-shaped restriction element is inserted into the insertion groove with an end. The restriction element prevents the switching button from falling. When the switching button is rotated, two sides of the restriction element selectively abut against the inner wall of the wrench to restrict the rotation range of the switching button.
