Abstract
The utility model relates to a screw driver head, and the structure comprises a screw handle part and a screw head part. The screw head part is provided with a plurality of edge angles. Edge angle standing faces are arranged among the edge angles. Antiskid teeth are arranged on the edge angle standing faces. Because a plurality of paths of antiskid teeth are arranged on the edge angle standing faces for the screw driver head of the utility model, skid can not easily occur in use and operation. Screws can be automatically and tightly geared, and skid and falling off can not easily occur. The density of the raw material can be improved after cold-forging. The utility model is firm and durable, and materials are saved.
