Threaded cutter used for oil exploitation and convenient to adjust

Abstract

The invention discloses a threaded cutter used for oil exploitation and convenient to use adjust. The threaded cutter comprises a threaded cutter head, a bearing and an extending rod. A connecting block is welded on and fixed to the top of the threaded cutter head, the connecting block and a fixed rod are fixed through a bolt, the bearing and the fixed rod are connected through penetration, each lateral side block is connected with one end of a corresponding supporting rod through a connecting shaft, a threaded tightening bush is installed on the connecting shaft, a built-in rod is arranged inside the other end of each supporting rod, one end of the extending rod is arranged inside the fixed rod, an installing block is fixed to the other end of the extending rod, a connecting groove is formed in the center of the upper surface of the connecting block, and installing holes are reserved symmetrically in the two sides of the exterior of the connecting block. By arranging the fixed rod andthe extending rod of telescopic structures, the using length of the threaded cutter can be adjusted; with the supporting rods and the built-in rods of telescopic structures, triangular supporting blocks realize supporting at different positions.

Description

technical field [0001] The invention relates to the technical field of thread cutters, in particular to an easy-to-adjust thread cutter for petroleum exploitation. Background technique [0002] Thread cutter is a kind of cutting tool. It is also widely used in oil exploitation, which brings a certain degree of convenience to oil exploitation. However, most of the thread cutter structures used in oil exploitation are relatively fixed. When it is installed After the equipment and devices are installed, the length cannot be adjusted according to the use requirements, which has certain limitations in use, and many thread cutters do not have a good fixed positioning function, so that the thread cutters are used during the process of use. The center cannot be well connected with the items that need to be processed, and it is prone to slippage and offset, which makes part of the oil extraction work inaccurate, which is not conducive to the oil extraction work. In view of the above...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an easy-to-adjust thread cutter for petroleum exploration, which solves the problem that most of the thread cutters used for petroleum exploration are relatively fixed in structure, and it is inconvenient to adjust the length according to the use requirements, and many The thread tool does not have a good fixed positioning function, so that the thread tool cannot be well connected with the items to be processed during use, and the problem of slipping and offset is prone to occur.
