The top cover 3 is also provided with a pole avoidance hole 11, the pole of the cylindrical battery can pass out from the pole avoidance hole 11, and the electrode exposure port 12 is provided on one side of the pole avoidance hole 11. The first support 1 and the second support are suitable for the poleless end and the pole end of the cylindrical battery respectively through the arrangement of the first support 1 and the second support, and the second support has the same side wall structure as the first support 1, which is convenient for the splicing combination of the first support 1 and the second support. In addition, the second support is spliced by the third support 2 and the top cover 3, and the pole avoidance hole 11 and the electrode exposure port 12 are respectively arranged on the top cover 3, which is suitable for the assembly of the electrode tab in the same direction cylindrical battery, and the pole avoidance hole 11 and the electrode exposure port 12 are arranged to shield other areas at the same time, which also plays an effective isolation protection when welding on the same plane.

[0025] In some embodiments, the top cover 3 is further provided with an isolation wall 13, which is located between the electrode clearance hole 11 and the electrode exposure opening 12. The isolation wall 13 is used to separate the electrode clearance hole 11 and the electrode exposure opening 12.

When welding the cylindrical battery, the welded current-carrying plate can extend from the first isolation channel to the outside of the first support 1.

[0027] In some embodiments, the maximum diameter of the first isolation channel is smaller than the diameter of the positioning through hole. When the electrodeless end of the cylindrical battery is fixed in the first bracket 1, the first isolation step 6 can play a limiting role.
