For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] The working principle of the above embodiment is:

[0032] (1) When the shell needs to be subjected to a pressure test, the shell is placed between two movable plates 207, and then the two electric push rods 201 are started to make the movable plates 207 on the left and right sides move relative to each other, and then the movable plates 207 on the left and right sides are made to contact the left and right sides of the shell.

At this time, the first gears 403 on the left and right sides start to rotate and drive the two second gears 404 to rotate. At this time, the third gears 405 on the left and right sides start to rotate, causing the shell to flip over, thereby achieving the purpose of adjustable angle. After flipping, the shell can be subjected to shell compression tests at multiple angles.
