Specific implementation mode

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work The every other embodiment obtained, shall fall within the protection scope of the present invention.

- 3 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of perforation processing carbide drill knot Structure, including top drill bit 1, the first connecting pole 2, middle part drill bit 3, end drill bit 5, rear end deck 6, shelves item 14 and the second connecting pole 15, the lower section of the top drill bit 1 is fixed with the first connecting pole 2, and first connecting pole 2 is fixed on the company of middle part drill bit 3 It connects in plane 4, the lower section of the middle part drill bit 3 is fixed with the second connecting pole 15, and second connecting pole 15 is fixed on end In the connection plane 4 of the top of drill bit 5, the lower section of the end drill bit 5 is welded on the rotation inner wall 13 of the bearing on rear end deck 6 On, the end drill bit 5 is made of gripping outer wall 9 and bearing rotation inner wall 13, and the gripping outer wall 9 and bearing rotate inner wall 13 Between be fixed with bearing 10, the side of the bearing rotation inner wall 13 is fixed with grade item 14.

Internal motivation being formd between the bearing rotation inner wall 13, space 11 being provided, the bearing rotates inner wall 13 and holds It holds and forms bearing rotation space 12 between outer wall 9, the bearing rotation inner wall 13 and the distance between hold outer wall 9 and be equal to axis 10 diameter is held, the outside of the top drill bit 1, middle part drill bit 3 and end drill bit 5, which is dug, thread groove 8, and thread groove 8 has Conducive to drilling, the end of the rear end deck 6 is fixed with port 7, and port 7 is used to enter pivot link.

Operation principle：Pivot link is inserted into internal motivation from port 7 to provide in space 11, when pivot link rotates When, it drives shelves item 14 and bearing rotation inner wall 13 to rotate, will not be rotated since the effect of bearing holds outer wall 9, people can pick up Outer wall 9 is held, middle (center) bearing 10 rotates inner wall 13 and drives end drill bit 5, middle part drill bit 3 and top drill bit 1 brill in front dynamic, It is middle bore it is dynamic during, the middle part drill bit 3 that small-sized drill mouth that top drill bit 1 drills out is conducive to rear bore the hole of bigger, equally The hole that drills out of middle part drill bit 3 be conducive to the end drill bit 5 at rear and drill out the dynamic of bigger.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is appreciated that can these embodiments be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
