Preferably, an L-shaped mounting rod is fixedly adhered to one side of the box body, which is far away from the oil filling hole.

Preferably, an oil discharge hole is formed in the inner wall of the bottom of the box body, and an oil discharge bolt is connected to the inner wall of the oil discharge hole in an internal thread mode.

Preferably, a bearing is arranged in the rotating hole, an outer ring of the bearing is fixedly adhered to the inner wall of the rotating hole, and an inner ring of the bearing is fixedly sleeved on the milling cutter body.

Preferably, an articulated block is fixedly adhered to the inner wall of one side of the box body, which is close to the oil filling hole, and the oil baffle plate is articulated with the articulated block.

Preferably, the one side that oil baffle is close to the oil filler point is pasted and is fixed with the rubber buffer, the diameter of rubber buffer equals with the diameter of oil filler point.

Compared with the prior art, the invention has the beneficial effects that: earlier pour into lubricating oil into in the box through the oil filler point before milling cutter body work, when lubricating gun injects in the oil filler point, the oil baffle uses articulated piece to do anticlockwise rotation as the centre of a circle, thereby alright pour into lubricating oil in the box in the past, when extracting lubricating gun, the spring just drives the oil baffle and uses articulated piece to do clockwise rotation as the centre of a circle, thereby the oil filler point has just been plugged up to the rubber buffer on the oil baffle, in milling cutter body work, lubricating oil in the box just can enter into the circular slot through six oil inlets, the lubricating oil of circular slot will be discharged through the multiunit oil outlet, thereby alright lubricate milling cutter body work in the time to it.

The invention has simple operation and convenient use, can lubricate the milling cutter while working, and improves the processing efficiency.
