摘要： The present disclosure provides a screwdriver tool assembly including a screwdriver tool and plural screwdriver bits. The screwdriver tool includes a main body, a cover, a working member, and an anti-detachment unit. The main body has a shaft member and a first axial hole penetrating the shaft member. The cover is arranged at a rear end of the main body and has a second axial hole. The working member is arranged at a front end of the main body and has a third axial hole. The first, the second, and the third axial holes communicate each other. The anti-detachment unit is adapted for preventing the screwdriver bit from moving backward to leave the screwdriver tool. Thus, the screwdriver tool assembly is able to receive plural screwdriver bits to be easy to carry. In addition, the process of changing the screwdriver bits becomes simpler.
