One end of the bottom frame 12 is mounted to one side of the opening via the hinge pivot 6, and the latch lock 7 is mounted on the other side. The bottom frame 12 can rotate horizontally. After the battery enters the fixture, rotating the bottom frame 12 pushes the battery forward. When the bottom frame 12 contacts the other end of the opening, it is locked by the latch lock 7. To prevent the battery from springing back, under the force of the elastic element of the bottom frame 12 and the probe 1, the battery terminal is in close contact with the probe 1, and the test connection is completed. After the test, pressing the latch lock 7 release button causes the bottom frame 12 to spring back to its original position, and the battery can be directly removed.

[0028] Preferably, the opening is larger than the width of the battery with the clamp, and the hinge rotation angle is greater than 90° to ensure that the battery push-in will not block the path. The latch 7 has a self-locking device and will not spring back after being pressed.
