In actual application, the movable heating plate 10 closest to the end fixed heating plate 8 is pushed inwards, and after the outermost aluminum plate contacts the battery cell, it continues to move to squeeze the battery cell onto the second aluminum plate. The two aluminum plates squeeze the battery cell to form a stable whole. The whole formed by the aluminum plate and the battery cell will continue to move inwards and contact with the next heating aluminum plate to squeeze the battery cell to form a new whole. And so on. After the last heating aluminum plate and the previous integrally squeezed battery cell form a complete whole, the clamp is in a clamped state.

[0029] In actual applications, the movable heating plate is tightened by the braided belt fixed by screws, and a preset fixed spacing is reached between two adjacent movable heating plates. The soft-pack battery cell or blade battery is placed between the heating aluminum plates, and the fixed nuts move inward to drive the conversion plate inward by synchronously rotating the T-shaped left and right screws on both sides, and then the first square column fixed on the conversion plate moves, and the end fixed heating plate moves inward synchronously, pushing the movable heating plate closest to the end fixed heating plate to move inward. After the outermost aluminum plate contacts the battery cell, it continues to move to squeeze the battery cell onto the second aluminum plate. The two aluminum plates squeeze the battery cell to form a stable whole. The whole formed by the aluminum plate and the battery cell will continue to move inward and contact with the next heating aluminum plate to extrude the battery cell to form a new whole. By analogy, after the last heating aluminum plate and the previous integral extruded battery cell form a complete whole, the clamp is in a clamped state.
