Excuse me, what tool is used to punch and install the "three-in-one connector" screw of furniture? Be specific. I'm going to buy it, but I don't know what it is

Excuse me, are you a friend of carpenter DIY?

Hand-made tools include hand drill, cross screwdriver, wooden tenon, etc., which are used to locate holes and prevent deviation. Need to use 6mm, 8mm, 10mm, 12mm bit, 8mm is mostly used for wooden tenon holes. There is also an installation method without white three-in-one nylon nut, called two-in-one connector, which is directly installed on the substrate with two-in-one screws. In fact, the effect is the same

Please refer to the attached drawings for the installation method.
