[0004] However, in reality, the old-style oil spray pipe 9 in this oil spraying mechanism is arranged between the push rod 2 and the transmission gear 6. Due to limited space, the distance between the old-style oil spray pipe 9 and the transmission gear 6 is often close, and thus it is easy to cause damage to the old-style oil spray pipe 9 during the operation of the transmission gear 6. In addition, the oil outlet hole has a fixed oil output for the lubricating oil, and the oil output cannot be freely adjusted. It is very easy for the front oil outlet holes to have a large amount of oil while the rear oil outlet holes have very little oil or even no oil, thereby reducing the oil spraying effect.

Due to limited space, the distance between the old-style oil spraying pipe and the transmission gear is often close, which can easily cause damage to the old-style oil spraying pipe during the operation of the transmission gear. In addition, the oil outlet hole has a fixed oil output for the lubricating oil, and the oil output cannot be freely adjusted. It is very easy for the front oil outlet holes to have a large amount of oil while the rear oil outlet holes have very little oil or even no oil, thereby reducing the problem of oil spraying effect.
