The positioning plate is that rectangle positions plate, and the jack on the positioning socket is rectangle jack, and the rectangle is fixed
The junction of position plate side and side is equipped with arc joint face.
Jack on the positioning socket runs through positioning socket.
It is provided with left connector above the left crankcase, right connector, the left connection are provided with above right crankcase
Mouth and right connector surround round connector, and the lower section of the cylinder block is equipped with the cylindricality being cooperatively connected with the round connector
Interconnecting piece.
The upper surface of the left crankcase is provided with third threaded connection hole, is provided in the cylinder block and the third screw thread
4th threaded connection hole of connecting hole cooperation.
The left crankcase is provided with the crankshaft hole passed through for crankshaft.
The utility model existing effect compared with background technique is:
Since the utility model uses above-mentioned scheme, which is provided with mutually matched positioning mechanism,
The specifically setting positioning plate at left crankcase bottom outer-edge, is arranged positioning socket at right crankcase bottom outer-edge, and positioning is inserted
The jack connecting with positioning plate is provided on seat can make left crankcase and right crankcase by positioning the connection of plate and jack
It fixes, and corresponds the threaded connection hole of left crankcase and right crankcase, conveniently serve as installation, accelerate installation effectiveness.
