Specific embodiment
In the description of the present invention, it should be understood that term " on ", "lower", "top", "bottom", "inner", "outside" etc.
The orientation or positional relationship of instruction be based on the orientation or positional relationship shown in the drawings or the utility model product use when
The orientation or positional relationship that the orientation or positional relationship or those skilled in the art usually put usually understand, be only for
Convenient for description the utility model and simplify description, rather than the equipment of indication or suggestion meaning or element must have specifically
Orientation is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
The utility model is further described with specific embodiment with reference to the accompanying drawing；
This gives a kind of automotive door hinge tail portion cutting edge fixing bolts comprising body part 01, car door part
02, one end of pin shaft 03, body part is fixed on vehicle body, and one end of car door part is fixed on car door, and pin shaft passes through body part
The other end formation of the other end, car door part is hinged, and car door part can be rotated around pin shaft；
It further include fixing bolt 04, fixing bolt includes twisting head 040, interconnecting piece 041, embedded division 042, interconnecting piece
One end is connected with twisting head, and the other end of interconnecting piece is connected with embedded division.
At hexagonal flower-shape, the twisting head of hexagonal flower-shape is more firm in the section on twisting head, and special spanner is needed to fasten
And disassembly, external screw thread is offered on the outer surface of interconnecting piece, internal thread hole is offered on body part, and interconnecting piece screws in internal thread hole
Interior formation is threadedly coupled, and bores 0400 transition connection, transition cone by transition between the bottom surface on twisting head and externally threaded top surface
