[0009] In the above-mentioned oil saw chain transmission piece, the guide oil hole penetrates the transmission piece body from front to back, so that the blade arranged alternately on the left and right sides can be connected to the guide oil hole.

[0010] In the above-mentioned oil saw chain transmission piece, the transmission piece body is in the form of a triangular structure, one corner of which forms a transmission bayonet, and the two straight edges on both sides of the transmission bayonet have an outwardly protruding arc-shaped part between them.

[0011] In the above-mentioned oil saw chain transmission piece, a plurality of heat dissipation holes are arranged on the lower side of the transmission piece body.

[0012] In the above-mentioned oil saw chain transmission piece, two shaft holes for penetrating the chain shaft are further arranged on the transmission piece body.

[0013] Compared with the prior art, the oil saw chain transmission piece has the advantages that:

[0014] 1、The oil guide hole structure that extends to the blade and the chain piece at both ends of the transmission piece body and can be connected with the blade and the chain piece respectively can make the area through which the lubricating liquid flows larger, improve the lubricating liquid coverage, and make the lubricating liquid on both sides of the transmission piece more evenly distributed, thereby achieving the purpose of reducing wear.

[0015] 2、The oil guide hole is in a strip shape, and the two ends of the oil guide hole can be connected with the blade and the chain piece on both sides of the transmission piece body respectively, so that the diffusion effect of the lubricating liquid is improved, the coverage of the lubricating liquid is larger, and the wear of the chain saw during operation is reduced.

[0016] Other advantages, objects and features of the present application will be apparent from the following description, and will be understood by those skilled in the art through the study and practice of the present application. BRIEF DESCRIPTION OF DRAWINGS
