Separating device suitable for safe hoisting of tight fit direct insertion module

The invention provides a separating device suitable for safe hoisting of a tight fit direct insertion module. The separating device comprises an upper separating device body, a screw assembly, a nut 6 and a lower separating device body. The lower separating device comprises a first supporting arm 2 and a lower separating seat 5, the upper separating device comprises a second supporting arm 10 and an upper separating seat 1, and the middle of the first supporting arm 2 is rotatably connected with the middle of the second supporting arm 10; during separation operation, the screw assembly drives the nut 6 to move downwards, so that the connecting end of the second supporting arm 10 and the nut 6 is driven to move downwards, the included angle between the first supporting arm 2 and the second supporting arm 10 is increased, the upper separation seat 1 is driven to move upwards, and the lower separation seat 5 is driven to move downwards; under the condition that the total height is small, the stretching operation
