Gravity loading hot-pressing furnace

The invention belongs to a pressure test device and relates to a gravity loading hot-pressing furnace tester. A test sample is placed in a furnace chamber of a provided gravity loading hot-pressing furnace; a lower support rod and a high-temperature press rod are arranged corresponding to the test sample; the upper end of the high-temperature press rod extends out of the furnace chamber and is connected with a high-temperature press rod fixation base on the top surface of the furnace chamber; the upper portion of the high-temperature press rod fixation base is connected with a ball head self-correcting mechanism through a pressure sensor; the ball head self-correcting mechanism is connected with a vertical gravity loading mechanism; the vertical gravity loading mechanism has a first-stagelever; the first-stage lever is hinged to one end of a connecting rod II; the other end of the connecting rod II is connected with the ball head self-correcting mechanism; one end of the first-stage lever is fixedly connected
