Description

[0002] With the development of energy storage technology, batteries are increasingly used in many fields. Batteries store energy through chemical energy, and convert chemical energy into electrical energy when needed to power equipment. When using batteries, it is necessary to connect the battery connection line to the battery pole. In existing batteries, there are many types of battery poles, and the structures are quite different. Some poles are cylindrical, some are in the form of blocks with through holes, and some are in the form of sheets with round shapes. Due to the large differences, when connecting the power cord, it is often necessary to configure a dedicated connection line, otherwise it is difficult to fully match. In particular, for some flat sheet poles, since the distance between the pole and the top cover of the battery is relatively small, the power connection line of a general battery is not easy to connect. Even if it is connected, there is a risk of falling off, so it is not convenient to use. And when using batteries outdoors, sometimes it involves the need to replace the battery to extend the power supply time. When the replaced battery model is different, a new power connection line is required, which obviously brings inconvenience to the carrying of the power cord. Summary of the invention
