[0029] In specific use, first, the lithium batteries needed to be welded are arranged on the top center of the base plate 20, and one corner of the lithium battery is attached to the inner corner wall surface of the fixed rod 21, then the handle 37 is lifted upwards, when the handle 37 is lifted upwards, the spring column 34 and the clamping ring 35 are synchronously moved upwards, the clamping ring 35 can drive the spring 36 to compress when moving, and the bottom of the spring column 34 no longer contacts with the wall surface of the base plate 20 in the sliding groove 30, at this time, the flap 32 is slid to contact with the wall surface of the lithium battery, and after the contact, the handle 37 is released, at this time, the spring 36 is released to drive the clamping ring 35 to move downwards to contact with the wall surface of the connecting block 33, and the spring column 34 contacts with the wall surface of the base plate 20 in the sliding groove 30 at this time to fix the position of the flap 32, when the flap 32 moves, the side rod 42 also synchronously moves to contact with the wall surface of the lithium battery, after the welding of the lithium battery is completed, the flap 32 is controlled in the same way to no longer contact with the wall surface of the lithium battery, finally, the welded lithium battery can be taken off from the top of the base plate 20;

[0031] As Figure 1 and Figure 4As shown, the wall surface of the side rod 42 is provided with an adjusting structure, which comprises an adjusting block 40, a bolt 41, a clearance slot 43 and a limiting plate 38. The adjusting block 40 is slidingly connected to the top of the movable plate 32. The bolt 41 is threadedly connected to the top of the adjusting block 40.

[0036] Working principle: first, arrange the lithium batteries needed for welding on the top center of the base plate 20, and make one corner of the lithium battery fit the inner corner wall surface of the fixed rod 21. Then, lift the handle 37 upwards. When the handle 37 is lifted upwards, the elastic column 34 and the clasp ring 35 are driven to move upwards synchronously. When the clasp ring 35 moves, it drives the spring 36 to compress. At this time, the bottom of the elastic column 34 no longer contacts the wall surface of the base plate 20 in the sliding groove 30. Then, slide the movable plate 32 to contact the wall surface of the lithium battery, and then release the handle 37. At this time, the spring 36 is released, driving the clasp ring 35 to move downwards to contact the wall surface of the connecting block 33. At this time, the elastic column 34 contacts the wall surface of the base plate 20 in the sliding groove 30, thereby fixing the position of the movable plate 32. When the movable plate 32 moves, the side rod 42 also moves synchronously to contact the wall surface of the lithium battery. After the welding of the lithium battery is completed, control the movable plate 32 in the same way to no longer contact the wall surface of the lithium battery. Finally, take the welded lithium battery from the top of the base plate 20.
