The utility model relates to a self-adaptive reset socket spanner. A needed replaceable socket head is selected, a cylindrical pin is connected with an attachment joint, a cold coiled compression spring is installed and compressed to the maximum compression amount, then the cylindrical pin is used for connecting the attachment joint with a handle, and the cold coiled compression spring is loosened; according to different working conditions, the cold coiled compression spring can be compressed to the maximum compression amount at the bottom of the replaceable socket head, the cylindrical pin is taken out, the original replaceable socket head is replaced with an appropriate replaceable socket head, the cylindrical pin is inserted again, the cold coiled compression spring is loosened, and the self-adaptive reset socket spanner is achieved. According to the self-adaptive reset socket spanner, the bending angle is large, the torque is large, the rotation direction is not limited, and practicability is high.
