[0083] In summary, when testing the insertion and extraction force of the electric meter and the electric meter connector, the electric meter connector is first installed in the placement slot of the fixed plate 800, and the electric meter is installed in the first movable seat 200. Then, the baffle 720 of the abutment member 700 is rotated so that the baffle 720 abuts against the bottom of the groove of the yielding groove, and the baffle 720 is partially placed inside the placement slot, and the baffle 720 abuts against the electric meter connector on the fixed plate 800 to prevent the electric meter from pushing the electric meter connector out of the fixed plate 800 when the electric meter and the electric meter connector are plugged in. When performing the insertion force test, the push rod 432 is pushed toward one side of the fixed plate 800, and the push rod 432 drives the hinged position of the hinge 431 and the connecting rod 420 to move, and is guided by the guide cylinder 440, and the connecting rod 420 moves in the horizontal direction. And because the connecting rod 420 is fixedly connected to the second moving seat 300, the connecting rod 420 will drive the second moving seat 300 to slide on the sliding rail, and the dynamometer 500 will move. And because the dynamometer 500 on the second moving seat 300 is detachably connected to the first moving seat 200, the movement of the dynamometer 500 will drive the second moving seat 300 to slide on the sliding rail, so that the electric meter on the second moving seat 300 gradually approaches the electric meter connector, until the electric meter and the electric meter connector are fully plugged in, the display screen on the dynamometer 500 will display the insertion force of the electric meter and the electric meter connector at the moment of plugging. Similarly, when performing a pull-out force test, the push rod 432 is pushed in the reverse direction, the second movable seat 300 moves in the reverse direction, and the force gauge 500 on the second movable seat 300 will pull the first movable seat 200 to move in the reverse direction, which will drive the electric meter on the first movable seat 200 and the electric meter connector on the fixed plate 800 to separate, and the setting of the placement slot can limit the movement of the electric meter connector, so that the electric meter connector has a maximum sliding distance, and when the electric meter connector abuts against the side wall of the placement slot, the electric meter is pulled out from the electric meter connector, and the display screen on the force gauge 500 will display the pull-out force of the electric meter and the electric meter connector at the moment of being pulled out.

[0084] In a possible implementation, the mounting base 100 is in the shape of a rectangular plate, and a plurality of support columns are disposed at the bottom of the mounting base 100 for supporting the mounting base 100 .
