AI Technical Summary

Problems solved by technology

[0003] Existing screwdrivers are all in the shape of a straight rod. A cross torx blade is added to the top of the screwdriver and inserted into the groove of the screw. When the screwdriver is rotating the screw, the user pinches the handle of the knife tightly with his fingers, and uses the fingers and the knife to tighten the screwdriver. The friction between the handles makes it rotate, driving the screw to rotate together, but this straight rod-shaped screwdriver is effortless when turning a screw with a small torque, but if it encounters a screw with a large torque, it is usually used. Hold the knife handle to increase the force arm to reduce the rotation force, but because the vise is not integrated with the knife handle, the knife handle often slips from the jaw of the vise when rotating, causing the screwdriver blade to be in the groove of the screw Slip deviation, damage the groove structure on the screw surface, and affect the efficiency of disassembly and assembly
