Shell extraction resistance simulation device

The invention discloses a shelling resistance simulation device, and the device comprises a clamping mechanism which comprises a right clamping claw and a left clamping claw, and the two clamping claws are oppositely provided with a first clamping arm and a second clamping arm which are respectively used for holding a cartridge case for a test and a bullet head for the test; the power mechanism is used for driving the right clamping claw and the left clamping claw to move in the same direction or opposite directions to realize clamping or separation of the clamping mechanism; the position identification mechanism comprises a first position detection unit and a second position detection unit; the first position detection unit is used for detecting the initial position of the clamping mechanism when the clamping mechanism is loosened; and the second position detection unit is connected with the firearm and is used for accommodating one part of the cartridge case for the test so as to detect whether the bullet e
