Power plant and it constructs to advance line knot thereof

The utility model relates to an advancing line knot and constructing, mountable in combustion engine main building, combustion engine main building include the frame roof beam and set up in the roof of frame back portion. It constructs including link unit and ground terminal unit to advance line knot. The link unit includes that the link built -in fitting reaches and link built -in fitting fixed connection's link board. The link built -in fitting can set up in the frame roof beam. The link board is kept away from the one end of link built -in fitting and is seted up the wire guide that runs through the link board. Ground terminal unit includes that the column base built -in fitting reaches and column base built -in fitting fixed connection's ground terminal. The column base built -in fitting can set up in the roof. The one end that the column base built -in fitting was kept away from to the ground terminal is provided with the ground wire orifice plate, offers the ground wire hole of running through the groun
