[0033] Description PN286327 HWYWLN

[0034] When the vertical extrusion test is performed, the extrusion part of the vertical extrusion mechanism is movably arranged above the clamping member 20. After the clamping member 20 fixes the battery, the extrusion part moves to the top of the battery and extrudes the top of the battery downward, so as to perform the vertical extrusion on the battery.

[0035] In the embodiment, the plurality of first positioning holes 11 are divided into multiple groups. The multiple groups of first positioning holes 11 are arranged at intervals along the arrangement direction of the clamping member 20.
