[0037] In this solution, the top of the crankshaft 24 is first connected to the power output source, and the bottom of the driving shaft 26 is assembled with the milling cutter. The power source drives the crankshaft 24, drives the sun gear 21 to rotate, and then drives the planetary gear 22 to rotate in the track inside the gear ring 23, thereby driving the planetary carrier 25, and finally drives the driving shaft 26 to drive the milling cutter. Through the cooperation of the sun gear 21, the planetary gear 22, the gear ring 23 and the planetary carrier 25, the torque of the driving shaft 26 is greatly increased by reducing the rotation speed of the crankshaft 24, so that various hard workpieces can be cut.
[0038] When the crankshaft 24 rotates, it drives the connecting arm 34 to transmit, and then drives the piston 32 to move inside the hollow tube 31, so as to suck and discharge the lubricating oil inside the outer box 1, thereby driving the lubricating oil to lubricate the entire milling group 2, thereby improving the overall working smoothness and service life of the milling group 2;

[0041] When in use, the additional milling group 2 sacrifices part of the rotation speed, thereby greatly increasing the torque of the driving shaft 26, so that various hard workpieces can be cut and processed, avoiding the problem of insufficient torque of the traditional electric spindle, which then makes it impossible to perform processing operations;
[0042] When the milling group 2 is working, the lubricating oil can flow inside the outer box 1 and filter the lubricating oil through the added hollow tube 31 and the filter plate 33, thereby lubricating the milling group 2, improving the smoothness of the milling group 2 when working, and improving the overall service life of the milling group 2;
[0043] When the two groups of hollow tubes 31 allow the lubricating oil to flow, the additional connecting arms 34 and pistons 32 are cross-operated inside the hollow tubes 31 to drive the lubricating oil to enter and discharge reciprocatingly, thereby greatly improving the fluidity of the lubricating oil, thereby improving the overall lubrication effect of the lubricating mechanism 3 on the milling group 2;
[0044] When the lubrication mechanism 3 is in operation as a whole, the anti-blocking mechanism 4 is driven to move by the internal pull rope 35. The added anti-blocking mechanism 4 can scrape the outside of the filter plate 33 to prevent the outside of the filter plate 33 from being blocked by impurities in the lubricating oil during use.
