AI Technical Summary
Technical Problem
In existing energy meter function testing devices, the fixation effect between the probe and the measuring instrument is poor, which easily leads to poor contact during the measurement process and affects the accuracy of the measured values.
Method used
A clamping mechanism was designed, including a support plate, a pressure plate, a rotating rod, and a fixed cylinder. By rotating the rotating rod and moving the fixed plate, the probe is tightly fitted between the support groove and the pressure plate. The extension and limiting mechanism of the spring is used to improve the fixing stability of the probe.
Benefits of technology
This improved the stability and accuracy of the electricity meter test, enhancing the device's practicality.

Abstract
This utility model relates to the technical field of electricity meter function testing, and in particular to an electricity meter function testing device. It improves the stability of the device when fixing the probe of the electricity meter to be tested, ensures the stability of the tester during the electricity meter testing process, improves the accuracy of the device's test values, and enhances practicality. The clamping mechanism includes a support plate with two symmetrical support grooves at its top. A pressure plate is fixedly installed at the bottom of the connecting groove via multiple first springs, and the pressure plate is slidably connected to the bottom of the connecting groove via a limiting mechanism. A fixing cylinder is fixedly installed at the top of the connecting groove via multiple brackets. A rotating rod is rotatably and slidably installed inside the fixing cylinder. A partition is fixedly installed on the outer wall of the connecting groove, and the rotating rod is rotatably and slidably connected to the partition. The rotating rod is fixedly connected to the partition via a fixing mechanism.
