There is a left through hole in the body, and the left through hole connects the left upper lying hole and the left lower lying hole. block and left locking nut, the left bottom fixing block is embedded in the lower left horizontal hole, and the left locking nut is embedded in the upper left horizontal hole; The arc inserting plate is connected with the right elevator, and the right slip body has a right through hole, which connects the right upper lying hole and the right lower lying hole, and the right arc inserting plate has a concentric right through hole, and the right through hole and the concentric right through hole Insert the right fixed rod, the right fixed rod connects the right bottom fixed block and the right locking nut, the right bottom fixed block is buried in the lower right lying hole, and the right locking nut is buried in the upper right lying hole. The invention is used for supporting slips of screw pumps in oil fields.

Description

Technical field: [0001] The invention relates to a novel oil field screw pump support slip. Background technique: [0002] The supporting slips used in the existing oil field screw pumps are of integral structure, and the inner side of the supporting slips has an elevator used in conjunction with the screw. Kava cannot be used as a whole, and it is wasteful to eliminate it as a whole. Invention content: [0003] The purpose of the present invention is to provide a novel oil field screw pump support slip that can replace the elevator, does not need to be eliminated as a whole, and has low use cost. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] A novel oil field screw pump supporting slip, which consists of: a left slip body and a right slip body, the inner side of the left slip body is a left semicircle, and a set of vertical arcs is formed on the left semicircle Arranged left arc slots, the left arc slots are inserted into the left ar...
