Plug adapter

Adapter from a europlug (CEE 7/16 2.5 A/250 V) to a cylindrical plug with grounding.
Increases the reliability of the connection, reduces the likelihood of the plug falling out of the socket, reduces the mobility of the connection.
It has a conical shape of both a cylinder and a recess for a socket.

I recommend using double-sided adhesive tape to fasten the adapter and plug.
