[0003] In the prior art, during the production process of products, if rivets are used to connect the tooling on the products, it is often necessary to detect the push-out force of the rivets on the riveted parts. Among them, the pressure testing machine includes a test bench body, and the test bench body is provided with a handle for the user to lift up or press down.

[0033] The signal output end of the pressure sensor in the pressure testing machine 1 is signal-connected to a pressure alarm module, and the pressure alarm module automatically alarms when the pressure borne by the rivet reaches the set pressure.

[0034] During the actual detection process, the user can place the tooling to be detected on the bearing platform 2, and then drive the pressing end 11 on the pressure testing machine 1 to press down to apply pressure to the rivet; when the pressure borne by the rivet reaches the set pressure, the alarm module issues an alarm to prompt the user that the pressure on the rivet reaches the set pressure value.

At this time, the user can observe the state of the rivet to judge whether the rivet is qualified.

[0037] It should be noted that in some other embodiments, the buzzer 3 can be replaced with an LED indicator light, which is not limited here.
