[0023] Preferably: The fixing mechanism includes: a mounting hole 18, a butterfly bolt 19 and a limiting hole 20. A mounting hole 18 is opened on one end surface at the top end of the column 8, a butterfly bolt 19 is connected through the inside of the mounting hole 18, and one end of the butterfly bolt 19 extends into a limiting hole 20 opened on one end surface of the movable column 10.

[0024] During specific use, the movable column 10 can move in the movable groove 9 on the column 8. When the position of a limiting hole 20 moves to the position of the mounting hole 18, the butterfly bolt 19 is passed through the mounting hole 18 and screwed into the limiting hole 20, so that the position of the movable column 10 can be fixed on the column 8. In this way, by adjusting the limiting hole 20, the position of the movable column 10 on the column 8 can be changed, so that the movable column 10 changes the position height of the positioning block 11.

[0025] Preferably: The battery cell 4 is slidably connected between the supporting groove 3 and the supporting block 2, and the upper clamping plate 7 is slidably connected between the positioning hole 6 and the positioning column 5.

[0026] During actual use, the battery cell 4 can be slidably placed in the bracket 3, so that the supporting block 2 holds up the battery cell 4.

[0029] Preferably: The insertion rod 14 forms a sliding connection with the positioning block 11 through the insertion slot 13, and the connecting block 15 forms a threaded connection with the screw rod 16.

[0030] During actual use, when the screw rod 16 is rotated in the bearing 17, the position of the connecting block 15 on the screw rod 16 will change, thereby causing the connecting block 15 to drive the insertion rod 14 to move, so that one end of the insertion rod 14 can be slidably inserted into the insertion slot 13, fixing the position of the positioning block 11 in the positioning slot 12.

[0031] Preferably: The butterfly bolt 19 forms a threaded connection with the limiting hole 20 through the through mounting hole 18, and the limiting holes 20 are longitudinally arranged in an array on the surface of one end of the movable post 10.

[0032] During actual use, passing the butterfly bolt 19 through the mounting hole 18 and screwing it into the limiting hole 20 can fix the position of the movable post 10 in the upright post 8. Multiple groups of limiting holes 20 are provided on the movable post 10, enabling the position of the movable post 10 to be adjusted.

[0033] Working principle of implementation: When using the cell fixture with a firm structure, first adjust the position of the positioning block 11 according to the size of the processed cell 4, so that the distance between the lower clamping plate 1 and the upper clamping plate 7 after clamping can adapt to the currently processed cell 4. By turning the butterfly bolt 19, one end of the butterfly bolt 19 is separated from the limit hole 20. At this time, the movable column 10 can move in the movable groove 9. In this way, when the positioning block 11 on the movable column 10 moves to the specified position, the butterfly bolt 19 can be turned again, and one end of the butterfly bolt 19 is screwed into the limit hole 20, so as to fix the position of the movable column 10, and the position of the positioning block 11 will also be fixed. At this time, the cell 4 can be slid and placed into the receiving groove 3 on the supporting block 2, and the cell 4 is placed at the specified position of the lower clamping plate 1. Then, install the upper clamping plate 7, and align the positioning hole 6 on the upper clamping plate 7 with the positioning column 5, so that the upper clamping plate 7 slides on the positioning column 5 through the positioning hole 6. In this way, the positioning block 11 will slide into the positioning groove 12 on the upper clamping plate 7. Then, turn the screw rod 16 to rotate in the bearing 17, and the connecting block 15 on the screw rod 16 can drive the insertion rod 14 to slide, so that one end of the insertion rod 14 slides and is inserted into the insertion slot 13 on the positioning block 11, and the position of the positioning block 11 is fixed in the positioning groove 12. In this way, the upper clamping plate 7 can be firmly connected to the lower clamping plate 1, and the upper clamping plate 7 and the lower clamping plate 1 clamp the cell 4. Align the liquid injection nozzle on the upper clamping plate 7 with the liquid injection hole on the cell 4, and then the cell 4 can be injected with liquid through the liquid injection nozzle. After the injection is completed, the screw rod 16 can be turned again, so that the connecting block 15 drives the insertion rod 14 to separate from the insertion slot 13. At this time, the upper clamping plate 7 can be easily separated from the lower clamping plate 1 by lifting it upward, so that the operator can load and unload the cell 4, and then process the next batch of cells 4. Through such a setting, the structure of the cell fixture is firmly connected, and at the same time, it is convenient to operate, avoiding the operator using tools to disassemble the fixture, thus saving operation time and improving the overall processing efficiency.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
