The fixed claw part 3 is used to clamp the differential housing 4 through the claw rod 32, the limit bracket 35, the limit screw 33 and the locking nut 34. Then, the pull screw 21 is pulled upward, and the pull screw 21 drives the fixed claw part 3 to move upward, and then the differential housing 4 is pulled upward. During this process, the data collector 7 collects the interference force data and draws the curve through the sensor 6. In this way, the differential housing 4 can be disassembled without damaging the differential housing 4, and the interference force of the differential housing 4 can be measured and collected.
