Embodiment
To be illustrated to the purpose, technical scheme and advantage of the embodiment of the present invention, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described.Described embodiment is the present invention
Part of the embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not having
There is the every other embodiment obtained on the premise of making creative work, belong to the scope of protection of the invention.
Embodiment 1
As shown in figure 1, a kind of spindle-less reaming bit instrument, including spindle-less reaming bit 1, drive rod 2, bearing pin 3, open
Mouth pin 4, wherein, spindle-less reaming bit 1 is made up of blade 5, cutter head 6, stick harness 7, tailstock 8；
Wherein,
Drive rod 2, it is cylindrical structure as shown in Fig. 7,8,9, left end is the face of cylinder, there is boss, the face of cylinder behind the face of cylinder
