the outer side of the lower surface of the upper shell is fixedly connected with a butt plate, and a plurality of second threaded holes are formed in the butt plate;

a plurality of grooves are formed in the upper shell, and threaded rods are movably arranged in the grooves.

Optionally, the lower shell and the upper shell are matched with each other, and the upper surface of the lower shell is attached to the lower surface of the upper shell.

Optionally, the butt joint groove and the butt joint plate are matched with each other, and the butt joint groove and the butt joint plate correspond to each other.

Optionally, the plurality of first threaded holes correspond to the plurality of second threaded holes one to one, and the plurality of grooves correspond to the plurality of second threaded holes one to one and are communicated with each other.

Optionally, internal threads are formed in the second threaded hole and the first threaded hole, and the second threaded hole and the first threaded hole are matched with the screw rod.

Optionally, the number of the first threaded holes is three, and the number of the second threaded holes is equal to the number of the first threaded holes.

The utility model discloses a technological effect and advantage:

1. the utility model discloses an internal-combustion engine housing comprises casing and last casing down, and when casing and last casing butt joint down, through the butt joint of butt joint board and butt joint groove, the connection leakproofness of casing and last casing under the improvement prevents that the heat in the internal-combustion engine housing from outwards letting out through the joint gap of casing and last casing down, and causes the damage to other equipment.
