[0032] In this embodiment, when in use, the collecting bottle 13 can be rotated to complete the installation and removal with the hollow tube 12, that is, the dripping oil is collected during operation and the collected oil is centrally processed after the collecting bottle 13 is removed.

[0041] Working principle: When in use, connect the external power supply and switch to the electrical equipment in this device, insert one end of the rotor to be processed into the circular cavity 501, and overlap the other end on the semicircular groove 1401, then rotate the screw 7, the screw 7 rotates and descends to make the connecting plate 8 descend, the connecting plate 8 descends to make the connecting rod 9 descend, the connecting rod 9 descends to make the arc pressure plate 10 descend to position the rotating end in the circular cavity 501, and then turn on the switch of the motor 4 to drive the connecting tube 5 to rotate and drive the rotor to be processed to rotate, and at the same time, perform oil spraying through the spray assembly 16. The specific process is the same as the prior art and will not be elaborated here.

[0042] During the oil injection process, as the rotor rotates, a small amount of oil will drip into the collection tank 301 under the action of gravity, and flow into the conical funnel 11 through the collection tank 301, and then flow into the collection bottle 13 through the hollow tube 12 for collection. When cleaning regularly, the collection bottle 13 can be removed from the hollow tube 12 by rotating it counterclockwise.
