Specific implementation mode
It is new below in conjunction with this practicality to keep the purpose, technical scheme and advantage of the utility model embodiment clearer
The technical solution in embodiment is clearly and completely described in attached drawing in type embodiment, and following embodiment is for illustrating this
Utility model, but be not intended to limit the scope of the present invention.
Embodiment 1
Referring to shown in Fig. 1-4, the utility model provides a kind of minor diameter bar type horizontal well auxiliary tool, including shell, sets
Set wet joint female assembly and wet joint male connector assembly in the shell, wherein the wet joint male connector as shown in Fig. 2, by
Wet joint male connector front, interconnecting piece, converter section composition, wet joint male connector front is connected through a screw thread with the interconnecting piece；
The wet joint female includes at least wet joint female front, female bar, several weighted levers as shown in Figure 3, before the connector female
Portion is connected through a screw thread with female bar, and mother's bar is connect with the weighted lever by crossover sub；It is provided with and helps in the shell
For positive cylinder as shown in figure 4, uniform ring is set there are three fixed module at the top of the righting cylinder, the fixed module is provided with screw thread up and down
Hole, the righting cylinder are connect with the shell by the upper screwed hole screw, and the righting cylinder inner wall corresponds to the stent
