At the rotary table center line of the rotary table metal block and the axial line of the body of rod coincide, and rotary table bottom center is fixed on adjacent rotary table
End face center position, rotary table top surface and adjacent rotary table junction form the back-off tooth for being used for the big part of the small inner hole of snapping collar extension,
The connection-peg is fixed on the end face of the body of rod by straight grain bar.
As a further solution of the present invention: the maximum outside diameter of the straight grain bar is equal to the maximum outside diameter of connection-peg.
It is opened up on the side wall of the straight grain bar along the axis direction of the body of rod as a further solution of the present invention,
There is a plurality of straight grain slot.
Knife-edge is arranged in the corner of the straight grain slot and back-off tooth as a further solution of the present invention,.
The body of rod, rolling tooth head, connection-peg, straight grain bar integrally use as a further solution of the present invention,
1022 steel be integrally formed, the body of rod, rolling tooth head, connection-peg, straight grain bar surface be all made of trivalent indigo plant zinc Passivation Treatment.
Compared with prior art, the utility model has the beneficial effects that the body of rod of the utility model setting passes through both ends not
The rolling tooth head and connection-peg of same connection type can be sequentially connected to the part of two kinds of different connection types, structure letter
Change, greatly reduce the bindiny mechanism of different parts, reduce connection space, integrated connect enhances the firm of connection
Property, it ensure that the stablizing effect of connection transmission.

Specific embodiment
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
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1
Please refer to Fig. 1~5, in the utility model embodiment, a kind of stock drive screw, including the body of rod 1, rolling tooth head 2, insert
Connector 3 and straight grain bar 4, the both ends of the body of rod 1 distinguish the fixed rolling tooth head 2 for being connected with screw hole part spiral and
Enter the connection-peg 3 of the big part of the small inner hole of collar extension for beer, the rolling tooth head 2 is the metal column that surface offers thread groove, institute
It states connection-peg 3 to be made of the fixed truncated cone-shaped metal block of multiple stackings, rotary table center line and the body of rod 1 of the rotary table metal block
Axial line coincides, and rotary table bottom center is fixed on the end face center position of adjacent rotary table, and rotary table top surface is connect with adjacent rotary table
Place forms the back-off tooth for being used for the big part of the small inner hole of snapping collar extension, and the connection-peg 3 is fixed on the end of the body of rod 1 by straight grain bar 4
On face.
The maximum outside diameter of the straight grain bar 4 is equal to the maximum outside diameter of connection-peg 3, and the main purpose of setting is when connection-peg 3
When beer is entered in the big part of the small inner hole of collar extension, straight grain bar 4 can be stuck in beer entrance inner wall, the big bottom surface of 3 truncated cone-shaped of connection-peg
It can be stuck in the biggish inner hole of part, guarantee the compactness that connection-peg 3 connects.
A plurality of straight grain slot, the straight grain slot master of setting are offered along the axis direction of the body of rod 1 on the side wall of the straight grain bar 4
After entering convenient for 3 beer of connection-peg, the beer entrance of straight grain slot enhancing 4 ontology of straight grain bar and part that straight grain bar 4 is arranged directly rubs
