The cylinder telescopic rod of the sealing cylinder is connected to the plugging mechanism, which is used to drive the plugging mechanism to block the side hole of the communication equipment cavity. The main problem with this airtightness test base plate tooling is that each model of communication equipment cavity needs to be configured with a corresponding airtightness test base plate tooling. When different communication equipment cavity products need to be tested for airtightness, the entire airtightness test base plate tooling needs to be replaced on the airtightness test equipment (the structure of the airtightness test equipment can be found in another patent application 202310758954.8 of the applicant), and the airtightness test base plate tooling needs to be adjusted and positioned before the airtightness can be tested.
