[0025] Specifically, the inclined surfaces and right-angled grooves on the two moving seats are respectively used to meet the positioning and placement of cylindrical and cubic batteries, thereby increasing the versatility of the positioning fixture; that is, the cylindrical battery can be positioned and placed horizontally between the two inclined surfaces. While realizing the positioning and placement of the battery through the guiding and limiting of the two inclined surfaces, at this time, one end tab of the battery is positioned and placed in the tab positioning groove, and the adjusting pressing block limits and abuts against the other end of the battery, thereby forming the limiting and positioning of the battery; when it is necessary to assist in welding the tab of the cubic battery, the cubic battery can be positioned and placed in the right-angled grooves on the two moving seats.

[0026] And the first driving member is used to drive the two moving seats to move relatively closer or farther away, so as to meet the positioning and placement of batteries of different specifications;

The two moving seats 5 are respectively threadedly connected to the first thread section and the second thread section in a one-to-one correspondence, and the two moving seats are movably sleeved on the first guide shaft 72 through linear bearings. Specifically, by screwing the first screw rod, the moving seat can be driven to move along the axial direction of the first guide shaft through the first screw rod. Also, because the thread rotation directions of the first thread section and the second thread section on the first screw rod are opposite, the two moving seats can be driven to move relatively closer or farther away.

[0030] Further, a threaded hole 11 is provided on the base 1, and the adjusting pressing block 6 is provided with an elongated slot hole 12 corresponding to the threaded hole 11.
