[0046] The working principle is that when drilling, the driving motor 2 is started to drive the base body 41 to rotate, and then drive the bottom transmission rod 42 to rotate, the transmission rod 42 drives the first docking ring 45 to rotate through the lower cross rod 44, so as to drive the transmission assembly 6 to rotate through the first docking ring 45, and the transmission assembly 6 drives the drilling assembly 9 to rotate to drill the valve fitting, and at the same time, the internal synchronous rotation transmission is realized through the meshing of the tooth block 115 and the bottom cylinder 7, and then the internal core assembly 8 rotates synchronously, and the closed plug 13 extends from the discharge groove during the drilling process, and then the discharge groove channel is opened, so that the cooling oil in the storage barrel 12 can enter the discharge groove through the groove 83 and the flow channel 84, so that the cooling oil can be automatically discharged for lubrication and cooling during the drilling process, and the wear and thermal decay of the cutting end block 93 are reduced, when the cooling oil in the storage barrel 12 is gradually reduced to a certain extent, the storage barrel 12 is lifted by the first spring 105, and then the top rod 47 is lifted by the top rod 47, and the top end of the top rod 47 is opened, and then the cooling oil in the base shell 51 flows downward and flows into the storage barrel 12 along the ring at the top of the storage barrel 12 to supplement, and after the supplement is completed, 48 is automatically closed under the self-weight of the cooling oil, and the automatic and continuous operation of the whole equipment is realized.
