Description of the Invention: [Technical Field] The present invention provides a hand tool, and more particularly to a wrench in which a handle can be pivoted relative to a tool head. [Prior Art] Regarding the locking or loosening of a fixing member such as a screw, it is generally operated by a hand tool such as a wrench. The hand tool generally includes a tool head and a handle that can be held by the user, and the end of the handle is coupled to the tool head such that the torque applied by the user to the handle can be transmitted to the tool head. Again, the handle is typically configured to be rotated relative to the tool head to allow the user to change the angle of the handle relative to the tool head as desired by the operating environment. Specifically, the handle can be 180 with respect to the tool head. Make the hand tool a straight shape or 90 in the tool head. Make the hand tool L-shaped. The handles that can form different angles relative to the tool head are advantageous for operation, however, when the hand tool is operated in a mode in which the handle is 90 with respect to the tool head. When the user holds the handle about the axial direction perpendicular to the tool head, the process is often uncomfortable due to the unsatisfactory position of the hand and the wrist, which adversely affects the operational flexibility. Therefore, for different angles of rotation operation, it is generally required to use different hand tools for performing β. SUMMARY OF THE INVENTION It is an object of the present invention to provide a hand tool that can improve the above problems, which allows a user to make a tool head relative to the handle. Hey. 18〇. Or in other angled modes of operation, the handle can be selectively adjusted to rotate about the axis of the handle or not to provide comfortable and labor-saving operation.
