Because - the 2-prong socket is NOT connected to earth !.. Any fault in the appliance - could result in electrocution.
If you are just sticking a piece of pipe on the handle so you (as the user) can apply more force to the tool, no, it won't change the ability to get a desired torque on a fastner. And adding an extension between the socket and the drive head of the wrench (a so-called socket extension) to extend the reach of the tool won't negatively affect the performance of the tool, either. The tool must be used properly in either case to get accurate results, but the torque wrench's ability to deliver correct results in accordance with the settings on it won't be diminished. If the tool is the so-called beam-type torque wrench, again, no, you shouldn't have a problem as long as you work carefully.

Each port can have a single passive socket, awaiting incoming connections, and multiple active sockets, each corresponding to an open connection on the port. Port identifies a service no. e.g.25 port no is for smtp
