If the user needs to change the screwdriver bit from time to time, that is, the limiting part that is detached from the screwdriver bit slot must be continuously put back into the screwdriver bit slot. When the operating environment is relatively narrow, it is not easy to pick up the screwdriver bit that has fallen to the ground. It can be seen that the convenience of use is limited and the work efficiency is reduced.
