The invention discloses an oil smearing tool for a buffer block. The oil smearing tool comprises an oil nozzle fixing seat, a first oil nozzle and a second oil nozzle. A cavity containing oil is formed in the oil nozzle fixing seat. The first oil nozzle is detachably connected with the oil nozzle fixing seat and used for spitting out the oil. The second oil nozzle is detachably connected with the oil nozzle fixing seat and used for spitting out the oil. According to the oil smearing tool for the buffer block, the oil is evenly smeared onto the two ends of the buffer block, and the oil smearing effect is good. In addition, the amount of the smeared oil is easy to control, so that waste is avoided, and the smearing efficiency is improved.
