An H-shaped fixing seat 12 is provided on the positive electrode welding ring 2, and both ends of the H-shaped fixing seat 12 are rotatably connected to opposite sides of the two connecting rods 11 respectively.

[0031] Furthermore, by flattening the copper wire into a V shape through the provided movable block tip 9 and the clamping and fixing block 4, the contact area between the copper wire and the clamping and fixing block 4 can be increased so that the connecting wire and the cylindrical sodium ion battery body 1 can be stably connected, and the elastic deformation generated by the provided limiting fixing ring 14 can enable the clamping and fixing block 4 to continuously have a force to press the copper wire on the clamping and fixing block 4, thereby further ensuring the connection stability of the positive and negative electrodes of the cylindrical sodium ion battery body 1.
[0032] Working principle: When in use, by pulling the pull ring 13 upward, the pull ring 13 will drive the H-shaped fixing seat 12 to move upward. When the H-shaped fixing seat 12 moves upward, the connecting rod 11 thereon will drive the two clamping movable blocks 8 to approach each other under the action of the slide bar 7. At this time, there will be a certain gap between the movable block tip 9 and the clamping fixed block 4. At this time, the connecting wire ends that need to be connected to the positive and negative electrodes of the cylindrical sodium ion battery body 1 will be peeled off. There is no need to twist the wire ends. Just insert them directly into the corresponding connecting holes 15 until the copper wire part of the connecting wire enters To the gap between the movable block tip 9 and the clamping and fixing block 4, at this time, by pressing down the pull ring 13, the pull ring 13 will drive the H-shaped fixing seat 12 to move downward, so that the two movable block tips 9 are pressed tightly in the corresponding clamping and fixing block 4 through the connecting rod 11 thereon, and at the same time, the limiting fixing ring 14 produces a certain degree of elastic deformation. At this time, the copper wire located in the gap between the movable block tip 9 and the clamping and fixing block 4 will be flattened into a V shape.
