Extend to form connecting shaft along central shaft in the middle part of the one end in blade portion, one end that the first blade portion connects the second blade portion is provided with
The axial hole corresponding with connecting shaft, the connecting shaft is interference fitted with the axial hole.
Further, described connecting shaft and described axial hole side wall are in the radial direction provided with the through hole run through, bolt
The first blade portion and the second blade portion are reinforced through the through hole combination nut in connecting shaft and axial hole side wall.
Further, the second described blade portion is provided with several, the first blade portion and some second blade portions it
Between deflector chute where helical orbit mutually coincide.
Further, cooling duct, institute are provided with along the spiral guide cell wall in the first blade portion and the second blade portion
Stating circulation in cooling duct has coolant.
Further, the initiating terminal and terminal of described cooling duct are arranged at handle portion, the cooling in the blade portion
Passage is in the shape of a spiral.
Further, described handle of a knife includes handle of a knife body and handle of a knife extending sleeve, and described handle of a knife body one end is nested in institute
State in handle of a knife extending sleeve.
Further, between some second blade portions between connected mode and the first blade portion and the second blade portion
Connected mode it is identical.
Further, the connection side between the connected mode of the handle of a knife and blade and the first blade portion and the second blade portion
Formula is identical.
Beneficial effect produced by the present invention includes 1, the quantity in the second blade portion can be adjusted according to actual borehole depth, when
After a certain section of blade portion is damaged, it is continuing with after the replaceable end blade, strong adaptability；2nd, the blade portion in the present invention is provided with cold
But passage, the temperature of hole wall and cutter can be cooled down in time in boring procedure, a series of problems caused by preventing temperature too high；3、
Handle of a knife is provided with handle of a knife extending sleeve, and the length of handle of a knife can be adjusted as needed, further increases adaptability.
