Abstract
The utility model relates to a screwdriver with rotatable middle section, which comprises a handle, a middle section, a tail end and a bit. The bit is arranged at the front end of the handle, the middle section is sleeved at the middle and rear end of the handle and can rotate relative to the handle, and the tail end is installed at the rear end of the handle and can rotate relative to the handle. The middle section and the tail end of the screwdriver can rotate relative to the handle body. When in use, the little finger, ring finger and palm can hold the middle section and the tail end to control the direction, and the thumb, index finger and middle finger can be used to rotate the handle. The utility model can meet the requirements of direction control when disassembling and assembling screws, increase the rotating force, meet the requirements of disassembling and assembling screws, and disassemble and assemble tighter screws compared with conventional screwdrivers. Meanwhile, the tail end can rotate freely. When used in the usual way, the utility model is no different from conventional screwdrivers in the prior art.
