Therefore, in actual operation, there is no need to replace corresponding test components, thereby reducing the test difficulty and test cost;

[0023] The translation assembly 7 includes a ball screw 701, both ends of which are rotatably mounted on the inner walls of the concave plate 5, one end of the ball screw 701 passes through the concave plate 5 and is connected to a drive motor 702, a moving block 703 is threadedly connected to the outer wall of the ball screw 701, and the drive motor 702 is set as a forward and reverse stepping motor;

[0024] Specifically, the drive motor 702 is started, and the output shaft of the drive motor 702 drives the ball screw 701 to rotate in a forward or reverse direction, thereby driving the moving block 703 to reciprocate along the axial direction of the ball screw 701;

[0025] It is worth noting that a limiting groove 11 is provided at the inner top of the concave plate 5, and a limiting block 12 adapted to the limiting groove 11 is fixedly connected to the top of the moving block 703, and the top of the limiting block 12 is slidably connected to the inside of the limiting groove 11.
