A left gear block and a right gear block are spliced, the spliced part of the left gear block and the right gear block is fixed through a fixing screw, oil storage grooves are formed in the two gear blocks, oil outlet grooves are formed in the edges of upper end openings of the oil storage grooves, groove covers are arranged on groove openings of the oil storage grooves, and the left gear block and the right gear block are fixed through fixing screws. The groove cover is spliced and fixed with the gear blocks through screws, an oil guide groove is formed in the outer side of a groove opening of the oil storage groove, the oil guide groove is communicated with the oil storage groove through an oil outlet groove, the oil guide groove is communicated with all tooth seams in the gear block, and a boss is arranged on the inner wall of any gear block; the device has the advantages that the left gear block and the right gear block are spliced, the installation mode that the end of the rotating shaft must be sleeved
