High-pressure movable elbow

The invention provides a high-pressure movable elbow. The high-pressure movable elbow comprises an inner movable elbow body and an outer movable elbow body, wherein an inner semi-ring rolling groove is formed in the outer movable elbow body, an outer semi-ring rolling groove is formed outside the inner movable elbow body, and the inner semi-ring rolling groove and the outer semi-ring rolling groove are correspondingly matched to form an annular containing groove. An annular rotating body comprises multiple groups of rotating body units combined in an annular distribution. Each rotating body unit comprises a first half rotating body, a second half rotating body, a first adjusting block and a second adjusting block, wherein the first adjusting block and the second adjusting block are located between the first half rotating body and the second half rotating body. A first tangent plane matched with the inner wall of the inner semi-ring rolling groove and a second tangent plane matched with the inner wall of the o
