End face has the locating piece of the arc set along spiro rod section periphery, and the lower surface of the spiro rod section is provided with the positioning with its upper surface
The card base that block is interlocked；The lower surface of the screw terminal is provided with the card base matched with the locating piece of spiro rod section upper surface；It is described
The upper surface of tail point section is provided with the locating piece coordinated with the card base gap of spiro rod section lower surface.
Further, the card base is in " L " shape, and the locating piece is provided with locating slot to the side at spiro rod section center, described
Locating slot include horizontally disposed and one end be the first locating slot do not closed and be vertically arranged and upper end connection first determine
The vertically oriented groove of the blind end of position groove.
Further, the lower surface of the screw terminal and spiro rod section is equipped with lug boss, the spiro rod section and tail point section
Upper surface is equipped with the groove coordinated with the lug boss gap.
Further, the screw terminal, spiro rod section and tail point end can use the metal of unlike material.
The beneficial effects of the utility model are：, can be first by screw terminal, a screw rod when station borehole length is deep
Section and tail point section are assembled, and card base is entered by the not blind end of the first locating slot, is then pressed downward by vertically oriented groove
Close so that lug boss is embedded among groove, complete to drill to station after fixing, screw terminal is removed after finishing, then
Increase a spiro rod section, the card base of spiro rod section lower end and the locating piece of spiro rod section upper surface pierced in station match installation,
Then install screw terminal continue station is drilled, efficiently avoid because self-tapping screw it is oversize caused by location difficulty,
The problems such as drilling deviates, and self assembly work is more laborsaving.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is radial section schematic diagram of the present utility model；
Fig. 3 is the structural representation of the locating slot of locating piece.
Embodiment
The utility model is further described below in conjunction with accompanying drawing：
A kind of segmented self-tapping screw as shown in Figure 1 to Figure 3, including be sequentially connected screw terminal 1, some spiro rod sections 2,
And tail point section 3, the periphery of spiro rod section 2 and tail point section 3 is equipped with screw thread 31, and the diameter of the screw thread 31 is along spiral upward direction
Gradually increase；The upper surface of the spiro rod section 2 has the locating piece 4 of the arc set along the periphery of spiro rod section 2, the spiro rod section 2
Lower surface be provided with the card base 5 being interlocked with the locating piece 4 of its upper surface；The lower surface of the screw terminal 1 is provided with and spiro rod section 2
The card base 5 that the locating piece 4 of upper surface matches；The upper surface of the tail point section 3 is provided with and determining that the lower surface of spiro rod section 2 matches
Position block 4；Any spiro rod section 2 can be added according to required length；The lower surface of the screw terminal 1 and spiro rod section 2 is all provided with
Have a lug boss 6, the upper surface of the spiro rod section 2 and tail point section 3 is equipped with the groove 7 coordinated with the gap of lug boss 6, be from
The torsion of radial direction is provided when tapping drills.
Further, the card base 5 is in " L " shape, and the locating piece 4 is provided with locating slot, institute to the side at the center of spiro rod section 2
State locating slot include horizontally disposed and one end be the first locating slot 41 do not closed and be vertically arranged and upper end connection the
The vertically oriented groove 42 of the blind end of one locating slot 41；In order to allow card base 5 to be easier to enter in locating slot, the first locating slot 41
Blind end is not additionally provided with a limiting section 44；The use of this buckle structure is in order to which screw terminal 1, spiro rod section 2 and tail point end 3 exist
Mutually fastening while, not only can be mutually radially fixed, and can also be axially secured to each other, in other articles of precession
