The present invention relates to hand tools, especially to a driving tool.

Generally, driving tools such as wrenches are used to turn fasteners (such as screws, nuts), and it is understood that the torque is proportional to the force arm or force. Therefore, to obtain a larger torque is nothing more than increasing the length of the wrench. Or use a hammer to increase the force.

However, an excessive increase in the length of the wrench will also increase the demand for the rotating range, which is very easy to collide with other objects in the surrounding environment and get stuck, resulting in unsmooth rotating operation and cannot be used in a small space. However, the way of increasing the force through the hammer hit, the wrench is prone to sliding with the fastener due to the improper hit angle, causing friction loss or falling.

Therefore, it is necessary to provide a novel and progressive driving tool to solve the above-mentioned problems.
