Lower advantage:
1 compared with traditional vertebral body structure the utility model annular board width it is short, turn construction when substantially reduce
Turning radius shortens construction length, improves construction efficiency；
2, the setting of pick box has evaded tradition time expansion device due to failure caused by bearing and gear wheel damage, extends and uses the longevity
While life, when reparation, only needs replacing pick box, has saved maintenance cost；
3, it is welded between the upper surface and wing plate or annular slab of the trapezoidal connector of pick box, during using, with mandrel
Rotation, the rotating path self-assembling formation of the drill bit of the pick box helix axially extending along mandrel, reduce drill bit abrasion and
Vibration when work, greatly improves cutting hardness；
4, sprinkling seat and pick box are correspondingly arranged, and guarantee cutting coolant being uniformly distributed between pick box, reduction is cut
Resistance is cut, in a certain range by cutting temperature control；
5, the setting of vertical plate plays positioning and supporting role to wing plate, keeps total more stable.

Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As depicted in figs. 1 and 2, the pick formula of the present embodiment returns expansion device, including mandrel 1, and 1 outer ring of mandrel passes through multiple wing plates
2 are connected with the annular slab 6 coaxial with mandrel 1, and multiple wing plates 2 are uniformly arranged along mandrel 1 is circumferentially-spaced, and each wing plate 2 is at fan
Shape structure；It is radially spaced on each wing plate 2 to be evenly equipped with a column pick box 4 and a column sprinkling seat 3；Along 6 upper surface one of annular slab
Circle interval is equipped on multiple pick boxs 4；The structure of pick box 4 are as follows: including axis 41,41 upper end of axis, which is extended axially by, to be cut
The drill bit 44 of dentation, 41 lower end outer cover of axis are equipped with cylindrical shell 42, and extending radially outwardly along cylindrical shell 42 has trapezoidal company
