Specific embodiment
The utility model is described in further detail with attached drawing combined with specific embodiments below, but the utility model
Protection scope be not limited to these examples, it is all without departing substantially from the utility model design change or equivalent substitute be included in
Within the protection scope of the utility model.
As shown in Figure 1, a kind of downhole cable rapid presser thread device of the utility model, including crimping nut 1 and card line device
2, the card line device 2 is polyhedron shape, and the card line device 2 is internally provided with a cavity, the 2 front and back phase of card line device
The corresponding square hole 3 of size and location there are two being provided opposite to, there are two size and positions for about 2 opposite face of the card line device setting
Set corresponding internal thread circular hole 4；The crimping nut 1 is hollow cylindrical structure, and inside hollow portion is circle, and inside is provided with interior spiral shell
Line 5, outside are provided with external screw thread 6, and the internal thread of the external screw thread 6 and the internal thread circular hole 4 is mating setting；The crimping nut
