The test piece can be installed horizontally after the test piece frame is laid down to a certain angle, which reduces the operational risk. At the same time, the opening of the test piece frame can be adjusted automatically, which reduces the labor intensity. In addition, the opening angle of the test piece can also be set on the computer, which can effectively control the opening angle of the test piece and realize failure and risk alarms.
