[0033] The centers of the multiple transverse grooves 4 are interconnected with the tops of the vertical grooves 5. The heat on the rear surface of the driving device 16 will be transferred to the inside of the vertical grooves 5 through the multiple transverse grooves 4, and the vertical grooves 5 will transfer the heat to the left side of the heat conductive block 3 for heat dissipation.

[0034] There are four groups of the mounting grooves 6 , the adjusting grooves 7 and the limiting grooves 8 , and the mounting grooves 6 , the adjusting grooves 7 and the limiting grooves 8 of each group are adapted to each other.
