Description

CROSS-REFERENCE TO RELATED APPLICATION This application International Application is a continuation of No. PCT/CN2023/101901, filed on Jun. 21, 2023, the entire content of which is incorporated herein by reference. TECHNICAL FIELD This application relates to the field of battery technologies and specifically to a battery test apparatus. BACKGROUND Currently, the insulativity, voltage resistance, and the like of a battery are primarily tested using a battery test apparatus. A battery test apparatus includes a lifting mechanism and a probe mechanism. The probe mechanism is fixedly connected to the lifting mechanism. The probe mechanism includes a plurality of probes. Distance between the probes matches distance between electrode terminals of battery cells in the battery. The distance between the electrode terminals is determined based on the size of the battery cells. The lifting mechanism can push the probe mechanism to a position close to the battery, allowing the probes to contact with the electrode terminals of the battery cells for testing the battery. To ensure accurate and reliable contact between the probes and the electrode terminals, the plurality of probes are typically fixedly mounted to the lifting mechanism, allowing for a fixed distance between the probes. When the size of the battery cells changes, there is a need to adjust the distance between the probes, such that the distance between the probes can match the distance between the electrode terminals. During adjustment of the distance between the probes, since there are a large number of probes that are all fixedly mounted to the lifting mechanism, it may take a long time to adjust the distance between the probes, making the battery test apparatus possibly unable to quickly adapt to batteries formed by battery cells of different sizes, thereby reducing the test efficiency of the battery test apparatus. SUMMARY Embodiments of this application are intended to provide a battery test apparatus, so as to resolve problems including but not limited to low test efficiency of battery test apparatuses in the related art because the battery test apparatuses cannot quickly adapt to batteries formed by battery cells of different sizes. An embodiment of this application provides a battery test apparatus including a lifting mechanism and a probe mechanism. The lifting mechanism is configured to drive the probe mechanism to move. The probe mechanism includes an adapting rack and a plurality of first connecting members disposed on the adapting rack. The adapting rack is detachably connected to the lifting mechanism. The probe mechanism is detachably connected to the lifting mechanism via the adapting rack. When the size of a battery cell changes and distance between probes needs to be adjusted, the adapting rack and the lifting mechanism can be separated first, and the probe mechanism is taken out of the battery test apparatus so that the distance between the probes is adjusted outside the battery test apparatus, reducing operation difficulty and improving adjustment efficiency, thereby shortening the time for adjusting the distance between the probes. As a result, the battery test apparatus can quickly adapt to batteries formed by battery cells of different sizes, thereby improving the test efficiency of the battery test apparatus. Alternatively, a standby probe mechanism may be provided. When the size of the battery cells changes, the adapting rack and the lifting mechanism can be separated, and the entire probe mechanism is directly replaced to implement quick model replacement so as to adapt to battery cells of different models, thereby improving the test efficiency. In some embodiments, the adapting rack is detachably connected to the lifting mechanism on one side and provided with two opposite first connecting portions on another side. The plurality of first connecting members are mounted between the two first connecting portions. In these embodiments of this application, the adapting rack is provided with the two opposite first connecting portions, and a plurality of first probes may be mounted between the two first connecting portions, so that the entire probe mechanism has a simple structure and a large operation space, allowing an operator to conveniently adjust or maintain the first probes between the two first connecting portions. In some embodiments, the probe mechanism includes a first guide rail; two ends of the first guide rail are connected to the two first connecting portions respectively; and the plurality of first probes are mounted to the first guide rail. In these embodiments of this application, the plurality of first probes being mounted to the first guide rail between the two first connecting portions can simplify the structure of the probe mechanism and reduce the weight of the probe mechanism, allowing an operator to conveniently dismount the probe mechanism. In some embodiments, the probe mechanism includes a plurality of first gui
