[0007] An adjustable drill and milling cutter for processing special-shaped holes includes a connecting rod, a mounting piece is installed at the bottom of the connecting rod, a drill bit is installed at the bottom of the mounting piece, a plurality of connecting pieces are installed on the surface of the mounting piece, a milling blade is installed on the surface of the connecting piece, and a mechanism for adjusting the milling blade is installed on the surface of the connecting piece.

[0008] Furthermore, the mechanism for adjusting the milling blade includes a slide groove opened on the surface of the connecting part, a slider is installed in the slide groove, and the slider is connected to the milling blade. It also includes a straight groove opened on the surface of the milling blade and a first thread groove opened on the surface of the connecting part, a first bolt is installed in the first thread groove, and the first bolt is located in the straight groove.

[0009] Furthermore, the drill bit is connected to the mounting piece via a detachable mechanism.

[0010] Furthermore, the detachable mechanism includes a plurality of connecting plates installed on the surface of the drill bit, the connecting plates and the connecting pieces correspond one to one, the surfaces of the connecting pieces and the connecting plates are both provided with second thread grooves, and second bolts are installed in the second thread grooves.

[0011] Furthermore, a positioning mechanism is installed on the surface of the drill bit.

[0012] Furthermore, the positioning mechanism includes a square block mounted on the surface of the drill bit, and a square groove matching the square block is formed at the bottom of the mounting member.

[0013] Furthermore, the connecting rod is fixedly connected to the mounting piece.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model cooperates with the connecting rod, the mounting piece, the drill bit, the connecting piece, the milling blade, the slide groove, the slider, the straight groove, the first threaded groove and the first bolt. When in use, the connecting rod is first installed on the main shaft. When the size of the special-shaped hole needs to be adjusted, it is only necessary to loosen the first bolt so that the milling blade is free from restraint. Then the milling blade is moved, and a suitable gasket is placed on one side of the milling blade and the other side contacts the mounting piece. Then, the first bolt is tightened and the gasket is removed. The gasket can make the adjustment distance of each milling blade consistent. The slide groove and the slider limit the milling blade. When the milling blade needs to be replaced, the first bolt can be completely unscrewed, and then a new milling blade is replaced, and then the first bolt can be installed.

[0016] By using the connecting plate, the second thread groove and the second bolt, the drill bit can be quickly replaced;
