In the implementation of the present invention, the metal fixing block 2 and the heat sink 3 are respectively disposed on both sides of the worktable, and the metal fixing block 2 and the heat sink 3 are operated to the machining point in the middle by the conveying mechanism, and the metal fixing block 2 is first moved to the predetermined position. Position, and then the heat sink 3 is moved to the upper side of the metal fixing block 2, since the heat sink 3 is provided with the through groove 21, when the connecting post 11 is combined, it can be smoothly inserted into the connecting post 11, and the heat sink 3 is attached to the heat sink 3 The surface of the metal fixing block 2; then the second metal fixing block 2 moves toward the processing point, the first metal fixing block 2 moves downward by a certain distance, and when the second metal fixing block 2 moves to the processing place, the second metal fixing block The connecting hole 15 of the rear side of the second side is opposite to the connecting post 11 of the first metal fixing block 2, the second metal fixing block 2 is pressed down to the connecting column 11, the upper end of the connecting post 11 is thickened, and the connecting post 11 The heat sink 3 is riveted to the connecting post 11 at the same time as the interference fit or fit with the connecting hole 15 and is repeated. The heat sink of the structure is riveted to the corresponding connecting post 11 by the metal fixing block 2, and the connection is stabilized, and the adjacent metal fixing block 2 is connected by the interference fit of the connecting post 11 and the connecting hole 15 Together, the entire heat sink 3 does not require a connector, but is compactly connected. Of course, if the machining accuracy is high, as the equivalent deformation, a through hole may be employed instead of the through groove 21.

The connecting post 11 can select its shape according to the processing conditions, such as a circle, a triangle, a polygon, and the like.
