Specific implementation mode
1-5 and specific embodiment make into one the structure, principle and the course of work of the utility model below in conjunction with the accompanying drawings
Step ground explanation, but protection scope of the utility model is not limited thereto.
It should be noted that embodiment provided by the utility model merely to this to the technical characteristic of utility model into
The effective explanation of row, the left side, right side, upper end, lower end etc. position word merely to being carried out to the utility model embodiment
Preferably description, is not to be regarded as being the limitation to technical solutions of the utility model.
A kind of gear hobbing tube-in-tube structure of connection vehicle body, including gear hobbing sleeve assembly and bolt 4, the gear hobbing sleeve assembly packet
Gear hobbing sleeve 1 and transition bracket 2 are included, internal thread is carried in the gear hobbing sleeve 1,4 surface of the bolt carries external screw thread, described
Gear hobbing sleeve 1 can be matched with the bolt 4 and is spirally connected, and the transition bracket 2 is the inverted ladder-shaped body knot of upper end opening, boring
