Problems solved by technology
The cutter head of the existing screwdriver is fixedly connected with the cutter bar as a whole, which is inconvenient to replace
In addition, there is currently a dual-purpose screwdriver on the market, which needs to be replaced at both ends, but it is laborious to replace. It is generally a direct plug-in type. Frequent replacement of the blade leads to loose connection of the plug-in interface, which affects the service life of the screwdriver. Therefore, this Invention Offers a New Way to Replace Bits in Screwdrivers
