Testing machine for simulating deep sea high-pressure torque

The utility model relates to a simulated deep sea high pressure torque testing machine which comprises a bottom plate, two ends of the top of the bottom plate are respectively provided with a first workbench and a second workbench through two height adjusting mechanisms, one end of the top of the first workbench is fixedly provided with a servo motor, and the output end of the servo motor is fixedly provided with a planetary reducer. Through a servo motor, a planetary reducer, a dynamic torque sensor and an adjusting rod, a valve rod to be tested is placed between a valve rod butt joint and two valve rod clamping blocks, the servo motor is started to drive the planetary reducer to rotate, then the dynamic torque sensor is driven to rotate, the torsion test of the valve rod is achieved, a first fixing bolt is loosened, and the valve rod is clamped. The adjusting rod slides in the vertical direction, then the first workbench and the second workbench are driven to move in the vertical direction, the overall heig
