And as the prior art, the technical content of some embodiments of the airtightness dry detection test bench is also in a public state. For example, the patent document with the application number 200420012063.0 discloses a "muffler airtightness test bench, which consists of a special flow-type detector, a workbench, a support frame, and a workpiece fixture part; among them, the special flow-type detector is fixed on the workbench, and the V-shaped adjustable support frame is connected to the support and fixedly connected to the workbench; one end of the support is fixed with a sealing block, the other end is fixed with a cylinder fixing seat, the positioning head is arranged on the sealing block, and the workpiece fixture is fixedly connected to the V-shaped adjustable support frame."

[0003] However, the above-mentioned prior art only proposes the technical concept of a workpiece fixture in the detection device for the workpiece to be detected. In reality, the specifications of the workpieces to be detected are diverse. How to adapt and clamp within a relatively large range is still a problem that needs to be solved by the airtightness dry detection test bench. Therefore, this application will propose an airtightness dry detection test bench to further solve the defects existing in the prior art. Content of the Utility Model

An electromagnetic chuck is magnetically connected to the bottom surface of the iron limit disk. The electromagnetic chuck is installed on the surface of the fixed clamping arc plate aligned with the other movable clamping arc plate. The combined magnetic connection effect of the iron limit disk and the electromagnetic chuck can stably guarantee the adjusted movable clamping arc plate.
