Above-mentioned, anchor clamps 1000 still includes base 1300, when electric core 100 carries out the clamping, places on base 1300, receives the bearing of base 1300. Since the clamping directions of the first clamping assembly 1110 and the second clamping assembly 1120 are perpendicular and parallel to the bearing surface of the base 1300, the first clamping assembly 1110 and the second clamping assembly 1120 form a planar clamping on the battery cell 100, which is parallel to the base 1300.

In the exemplary embodiment, first clamp assembly 1110 includes a first movable clamp arm 1111 and a first drive 1112, with first drive 1112 driving two first movable clamp arms 1111 toward and away from each other. The battery cell 100 is rectangular, two first movable clamping arms 1111 are disposed opposite to two wide sides of the battery cell 100, and when the first driving part 1112 drives the two first movable clamping arms 1111 to approach, the battery cell 100 is positioned in the length direction.
