Interior lance hook 302, the angle in adjacent two first between lance hook 302 is 90 degree；Alternatively, 6 can be distributed with each circumference
Lance hook 302 in first, the angle in adjacent two first between lance hook 302 is 60 degree.On each circumference first in lance hook 302
Quantity can differ, can also be identical.On two neighboring circumference first in lance hook 302 can shift to install.
When one it is provided circumferentially about have lance hook 302 in more than one first when, the length of lance hook 302 can be with each first
It is identical, can not also be identical；When the length of lance hook 302 in first on same circumference differs, the length of lance hook 302 in first
Degree can successively decrease setting, or in first lance hook 302 according to length the alternate setting of length.
Certainly, the set-up mode of lance hook 302 is not limited to this in first, and the present embodiment is merely illustrative of herein, except this
Outside, those skilled in the art can also be configured according to actual needs, as long as can realize that it hooks rope or clamping
The function of fish fish head.
It is appreciated that：, can be according to tool string when the upper end of the first adapter 100 connects different tool strings
Connection requirement, the first adapter 100 of upper end of the selection with corresponding size；The namely upper end of the first adapter 100 can be with
It is selective with sizes.
But the region that lance 300 is mutually matched is dragged in the middle part and first of the first adapter 100, size is fixed, such as respectively
The outside diameter at the middle part of the first adapter 100 is identical, and the internal diameter that the upper end of lance 300 is dragged in each first is identical；First adapter 100
The region that lance 200 is mutually matched is dragged for outside lower end and first, size is fixed, such as the internal diameter phase of the lower end of each first adapter 100
Together, the outside diameter of each first upper end for dragging for lance 200 outside is identical.So set, salvaging work is carried out to different oil wells in operating personnel
During industry, lance 200 can be dragged for outside lance 300 or first according to being actually needed in selection corresponding first to drag for, it is whole without replacing
Fishing device.
Fishing device provided in this embodiment for oil well, is provided with the first adapter 100, in the first adapter 100
Lower end be connected with outside first and drag for lance 200, be connected with the middle part of the first adapter 100 in first and drag for lance 300, outside first
It is different from the diameter that lance 300 is dragged in first to drag for the diameter of lance 200, so that during single fishing, fishing device
Can be salvaged for various sizes of fish, improve the adaptability of fishing device, and can salvage more fish and
Rope, improves salvaging efficiency.
