Problems solved by technology

[0002] A screwdriver is a hardware tool commonly used in people's work and life. The general screwdriver is mostly a single working head, which can only be used for one kind of screw. If there are many screws with different specifications and different installation methods on an item that needs to be disassembled, then It is necessary to carry or be equipped with multiple screwdrivers of different specifications, so it is very easy to miss one or two screwdrivers, which brings inconvenience to on-site use, and it is also troublesome to carry, and it is easy to cause loss; at present, there are some screwdrivers on the market. A combination tool composed of different types and specifications of screwdrivers, but there are still some shortcomings in applicability, some cannot meet the needs of night use, some cannot realize the force control function, some have fixed lengths and cannot be used in small spaces, and some cannot monitor whether the operating object is Electricity, what kind of potential, etc., so in actual use, carrying a combined tool can not solve the problem, or need to use another tool together, sometimes it is more troublesome
