The first connecting member 403 is arranged in a cylindrical tube shape. In other embodiments, the first connecting member 403 can also be arranged in a tubular shape, and the end of the first connecting member 403 does not protrude from the bottom surface of the placement table 3. A plurality of elastic electrical connecting members 404 are arranged on the inner wall of the first connecting member 403. In the embodiment of the present application, the elastic electrical connecting member 404 is an elastic spring sheet, which has conductive ability and is electrically connected to the connecting wire 402.

[0032] Corresponding, refer to Figure 4A second mounting groove 6 is provided on the side of the detection table 1 facing the sliding track 2, and the second mounting groove 6 is arranged on the sliding path of the placement table 3, and when the placement table 3 slides to the position of the second mounting groove 6, the first mounting groove 5 is arranged corresponding to the second mounting groove 6, and a second connecting member 7 is embedded in the top of the side wall of the second mounting groove 6, and the second connecting member 7 is arranged in a tubular shape. An elastic electrical connecting member 404 is also arranged on the inner wall of the second connecting member 7, and a driving member 8 is also arranged at the bottom of the second mounting groove 6.

[0040] The principle of the embodiment of the present application is that, during the battery detection process, the position where the movable electrical connection structure is electrically connected can be set as the detection station; any position at other positions of the slide rail is selected as the installation station. During the detection, the staff must connect the battery to be tested with the battery clamp 401 at the installation station, so that the battery to be tested forms a local circuit with the first connecting member 403, and then slide the placement table 3, the placement table 3 slides until it contacts the connecting rod 9, and applies a force to the protruding end of the connecting rod 9, the connecting rod 9 slides toward the bottom of the second installation groove 6, and abuts against the bottom surface of the placement table 3, when the placement table 3 moves to the corresponding arrangement of the first connecting member 403 and the second connecting member 7, the auxiliary blocking plate 13 rises to block the placement table 3, and at the same time, the connecting rod 9 moves toward the first connecting member 403 under the action of the driving member 8, and is electrically connected to the first connecting member 403, after the detection is completed, the auxiliary blocking plate 13 moves down, the placement table 3 slides away from the detection station, and slides in the rear placement table 3, which is convenient for the separation of battery installation and detection, and effectively improves the detection efficiency.
