Problems solved by technology

Existing screwdrivers that can replace screwdriver bits have the problem that multiple screwdriver bits are loosely arranged and easily lost when carrying
In some occasions that require a large torque to unscrew the screw, it is necessary to use an extra booster rod at the end of the screwdriver to open the screw. However, it is difficult to find a suitable booster rod in a short time on some occasions. It brings inconvenience to the work of screwing
This use situation requires the operator to carry a variety of screwdrivers to work on site, which increases the number of tools carried by the staff
