Problems solved by technology

[0002] During the assembly operation, the screwdriver is often used to load and unload the screw. The contact area between the screwdriver head and the screw of the traditional screwdriver is small. Although some screwdriver heads are magnetic, the magnetic force is relatively small. The adsorption force is relatively small. When loading and unloading the screws at a horizontal or inclined angle, the screws are easy to fall off. Sometimes you have to hold the screws by hand. The assembly is cumbersome and time-consuming.
