M3 weight level interface insulation heat conduction material compression tester and test method thereof

The invention discloses an M3 weight level interface insulation heat conduction material compression tester. The M3 weight level interface insulation heat conduction material compression tester comprises a horizontal foot margin, a suspended foot margin, a positioning base plate, a sample positioning sleeve, a sample withdrawing piston, a dished weight, a spirit bubble, a dial indicator and a height gauge, the horizontal foot margin and the suspended foot margin are connected with the bottom surface of the positioning base plate and are used for supporting the total weight of the instrument, adjusting the levelness and locking the elevation; at least three island-shaped platforms are arranged on the top surface of the positioning base plate, and the top surfaces of the island-shaped platforms are positioned in the same geometric plane; the inner diameter of the sample positioning sleeve is larger than the diameter of the island-shaped platform, so that the island-shaped platform can be sleeved or separated; t
