Rotary Screwdriver / Tool

Rotary Screwdriver
Rotary Screwdriver

Rotary Screwdriver uses a new type of turntable structure, similar to a revolver. And one turntable can hold up to 9 screwdriver heads of different specification, models and sizes. Only rotate the required screwdriver to 180 degrees when using. The turntable can accommodate both the screwdriver head and the handle of the screwdriver handle, increasing the arm for turning and providing more comfortable and labor-saving. This method greatly saves the tedious procedure of replacing the screwdriver head and is not easy to lose. The special keyhole is convenient for the screwdriver to hang around the waist.
