AI Technical Summary
Technical Problem
During the oil mining process, the shaft of the reamer is difficult to effectively limit the shaft in the drilling hole, which makes the shaft vibration difficult to control and affects the stability of the drilling hole size.
Method used
The auxiliary limit structure is designed with an oil mining micro -expansion, including semi -circular block A and semi -circular block B. There is a regulatory mechanism installed at the wall of the blocks. The composition of the board combines the cooperation of the threaded pole and the arc limitation board to achieve a limit on the shaft of the eye expansion.
Benefits of technology
Through the limit structure, the vibration of the eye expansion shaft is effectively avoided, and the drilling size is achieved.

Abstract
The utility model relates to the technical field of oil exploitation hole opener, in particular to an auxiliary limiting structure for an oil exploitation micro hole opener, which comprises a semicircular block A and a semicircular block B. Adjusting mechanisms are arranged on the block wall of the semicircular block A and the block wall of the semicircular block B. Each adjusting mechanism is formed by combining a threaded rod, a handle, an L-shaped plate and an arc limiting plate. L-shaped plates are welded to the block wall of the semicircular block A and the block wall of the semicircular block B correspondingly, threaded rods are connected to the plate walls of the L-shaped plates in a threaded mode, handles are installed at one ends of the threaded rods, arc limiting plates are connected to the other ends of the threaded rods through bearings, and a rotating shaft of the reamer is located between the arc limiting plates, so that the rotating shaft of the reamer is limited. And the drilling size is prevented from being influenced by vibration of the reamer rotating shaft.
