Specific embodiment
Here is that the present invention is further described in conjunction with the accompanying drawings and embodiments.
Referring to Figures 1 and 2, downhole tool installation friction grip, including friction block, multiple attachment devices and compression
Handle.
Wherein, friction block can be three, such as: friction block includes the first friction block 1, the second friction block 2 and third friction
Block 3, the first friction block 1, the second friction block 2 and third friction block 3 are the third cutting structure of full circle, and the first friction block 1, second rub
The internal diameter of cleaning block 2 and third friction block 3 is rounded, the outer round surface of the first friction block 1, the second friction block 2 and third friction block 3
Two parallel annular grooves 4 are respectively equipped with, the both ends of the first friction block 1, the second friction block 2 and third friction block 3 are respectively equipped with pin
Hole 5.The connecting pin of first friction block 1 and the second friction block 2 is linked together by the first connection board group 6, pin shaft 7 and pin hole 5.
The connecting pin of second friction block 2 and third friction block 3 links together also by the second connection board group 8, pin shaft 7 and pin hole 5.The
One connection board group 6 and the second connection board group 8 are separately mounted in annular groove 4, and the first connection board group 6 and the second connection board group 8 are divided
Not Bao Kuo two connecting plates, two connecting plates are separately mounted in two parallel annular grooves 4, are also machined at the both ends of connecting plate
Pin hole connects the first friction block 1, the second friction block 2 and third friction block 3 for wearing pin shaft 7, and thickness is slightly less than friction block
The 1 annular groove width of periphery two, so as to flexible rotating.Pin shaft 7 and friction block, connecting plate are interference fitted.In use not
Cause loose or dislocation.Similarly, friction block may be two, i.e. two semi-circular structures.
The end of first friction block 1, the second friction block 2 and third friction block 3 sequentially passes through the pin shaft of pin hole and connecting plate
It is rotatably connected to form turning end, another connecting pin of the first friction block 1 and third friction block 3 forms open end.
In addition, pressing handle includes handle body 9, one end of handle body is free end, and the other end is the U-shaped U in cross section
