Screwdriver head mounting structure

A screwdriver head mounting structure, comprising:

• a mounting base comprising a main body and an assembly portion coaxially formed on one end of the main body;
• the assembly portion defining a mounting hole axially extending to the main body;
• the main body defining an eccentric latching hole through a peripheral wall thereof, along a direction perpendicular to and eccentric to an axis of the main body;
• the eccentric latching hole partially intersecting with the mounting hole;
• an elastic member;
• a latching member adjustably assembled into the eccentric latching hole of the mounting base, the latching member comprising a pin body, a head portion formed at one end of the pin body, and a fixing end formed at the opposite other end of the pin body, the pin body defining a latching slot;
• a fixing member detachably fixed to the fixing end of the latching member;
• and
• a screwdriver head having a latching end inserted into the mounting hole of the mounting base, and latched with the latching member, wherein the fixing end of the latching member passes through the eccentric latching hole, the pin body is received in the eccentric latching hole, the elastic member is sleeved on the fixing end, opposite ends of the elastic member resist the fixing member and the main body of the mounting base, respectively, such that the latching slot and the spring are located at a same side of the mounting hole adjacent to the fixing member, the head portion resists the main body, and the latching end of the screwdriver head is latched in the mounting hole;
• when the elastic member is compressed, the latching member moves toward the mounting hole, and the latching slot aligns with the mounting hole, and the latching end is detached from the mounting hole.
