[0037] Reference Figure 1 , Figure 5 The moving component 6 includes a connecting plate 61, which is fixedly connected to the outside of the baffle 5. A motor 62 is fixedly connected inside the connecting plate 61, serving as the power source for the horizontal movement of the moving component 6.

[0039] Working principle: When a pressure test is required on a workpiece, the workpiece is first placed on top of the mounting plate 21.
