[0034] The detection pipeline also includes multiple branch pipes. The intake solenoid valve 43 and the exhaust solenoid valve 44 of the control component 40 can be set on the intake pipe and the exhaust pipe respectively.

The air intake switch and the pressure relief switch are each fixed to the test platform 10. To facilitate connection to an external air supply device, the test platform 10 may be provided with an air intake opening 10a and an air relief opening 10b for allowing pipelines to pass through, respectively, at positions corresponding to the air intake solenoid valve 43 and the air relief solenoid valve 44.
