[0035] In an optional embodiment, four support columns are disposed on the support base 100 , and the four support columns are disposed at four corners of the support base 100 .

[0036] Generally, four support columns are arranged on the support base 100 , and other numbers of support columns may also be arranged, such as two or three. The support columns on the support base 100 are used to support the upper support plate 200 so that a fixed distance is maintained between the upper support plate 200 and the support base 100 .

[0037] Reference Figure 1 In an optional embodiment, a hydraulic rod 400 is provided on one side of the support base 100, and the hydraulic lifting column 600 is raised and lowered by the hydraulic rod 400.

[0038] The hydraulic lifting column 600 is a prior art.

In order to separate the positive electrode case 170 from the extrusion head 160 .

[0051] An annular plate 140 is provided on the peripheral side of the extrusion head 160. When the positive electrode shell 170 is deformed, the second return spring 150 on the annular plate 140 is in a compressed state; when the positive electrode shell 170 cannot be separated from the extrusion head 160 on its own, the annular plate 140 applies a force to the positive electrode shell 170 to separate the positive electrode shell 170 from the extrusion head 160.

[0052] In an optional embodiment, the upper disassembly mold 130 is detachably connected to the lower support column 500 , and the upper disassembly mold 130 is detachably connected to the hydraulic lifting column 600 .
