FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry and can be used for research and development of reservoirs in wells. A device for installing an anchor suspension with a ball drive includes a housing with channels in which drive balls are installed, which engage when lifting the coupling clearance. The central rod with a spring is made with a shoulder located in its upper part for fixing the drive balls in the coupling gap. The tip is connected to the top of the stem for triggering the device using a cable, rope or wire. In the lower part of the stem, there is a glass connected to a spring in the upper part, and a cage with side holes. Additional balls are located in the holes of the cage and interact with a recess on the inner surface of the lower part of the glass. The armature head is located in the holder. Above the glass, an additional body with a spring placed in it and a sleeve with a groove are installed to accommodate the fixing balls interacting with the additional body and with a groove made on the stem.

EFFECT: increases the efficiency of the installation of the anchor suspension, by simplifying the design and increasing the reliability of the actuation of the drive balls.
