For reaching above-mentioned purpose, this utility model have employed following technical proposal: the turning cutting tool of this processing universal joint internal and external threads, it is characterized in that, including the handle of a knife in column, described handle of a knife one end is provided with the knife rest taken the shape of the letter U, and described knife rest outer end is respectively provided on two sides with the first cutter head and the second cutter head arranged inwardly.
In the turning cutting tool of above-mentioned processing universal joint internal and external threads, the first described cutter head and the second cutter head are all in triangle column.
In the turning cutting tool of above-mentioned processing universal joint internal and external threads, the first described cutter head and the second misplaced cutter head are arranged.
In the turning cutting tool of above-mentioned processing universal joint internal and external threads, the first described cutter head and the second cutter head are connected as a single entity structure with knife rest respectively, and described knife rest and handle of a knife are connected as a single entity structure.
In the turning cutting tool of above-mentioned processing universal joint internal and external threads, the first described cutter head and the second cutter head are that any one in white steel, wolfram steel, diamond, ceramic metal is made.
In the turning cutting tool of above-mentioned processing universal joint internal and external threads, the first described cutter head and the second cutter head are all coated with abrasion-resistant coatings.
In the turning cutting tool of above-mentioned processing universal joint internal and external threads, the first described cutter head and the second cutter head are connected by the first removable structure with knife rest respectively, and described knife rest is connected by the second demountable structure with handle of a knife.
Compared with prior art, the advantage of the turning cutting tool of this processing universal joint internal and external threads is: 1, reasonable in design, simple in construction, it is possible to increase working (machining) efficiency and raising yield rate.2, sound construction, service life is long.3, installing simply, easy to use, it is simple to the processing of product, the internal and external screw thread after processing is on same concentric circular.

Detailed description of the invention
As Figure 1-4, the turning cutting tool of this processing universal joint internal and external threads, it is characterised in that include that the handle of a knife 1 in column, handle of a knife 1 one end are provided with the knife rest 2 taken the shape of the letter U, knife rest 2 outer end is respectively provided on two sides with the first cutter head 3 and the second cutter head 4 arranged inwardly.
First cutter head 3 and the second cutter head 4 are all in triangle column, first cutter head 3 and the second cutter head 4 shift to install, first cutter head 3 and the second cutter head 4 are connected as a single entity structure with knife rest 2 respectively, knife rest 2 and handle of a knife 1 are connected as a single entity structure, first cutter head 3 and the second cutter head 4 are made for any one in white steel, wolfram steel, diamond, ceramic metal, and the first cutter head 3 and the second cutter head 4 are all coated with abrasion-resistant coatings；First cutter head 3 is connected by the first removable structure 5 with knife rest 2 respectively with the second cutter head 4, and knife rest 2 is connected by the second demountable structure 6 with handle of a knife 1.
First demountable structure 5 includes the union joint 51 that can the first cutter head 3 or the second cutter head 4 be fixed on knife rest 2, union joint 51 the inner is plugged in the first polygonal hole 21 of knife rest 2, union joint 51 is inner and the first polygonal hole 21 adapts, and union joint 51 and knife rest 2 are fixed by the first screw 52；Second demountable structure 6 includes the second screw 61 of immovable support 2 and handle of a knife 1, and described handle of a knife 1 is plugged in the second polygonal hole 62 of knife rest 2.
The using method of the turning cutting tool of processing universal joint internal and external threads, comprises the steps:
