[0025] The utility model is connected to the bottom of the carrier device of the sinking equipment through a buckle 31. Specifically, the bottom of the carrier device of the sinking equipment has a mounting plate, and the mounting plate has a mounting hole. The utility model is inserted into the mounting hole, and the buckle 31 is supported on the edge of the mounting hole. Then, the electric-controlled magnet 40 is magnetically fixed to the suction cylinder foundation, so that the carrier device can drive the utility model to rise and fall. The electric-controlled magnet 40 of the utility model is coated with rubber and placed inside the device. The electric-controlled magnet 40 is controlled by the electric control module 20 at the top of the device to realize the adsorption and detachment of the sinking equipment to the suction cylinder foundation.
