The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, a first embodiment of the present invention provides a welding fixture for a side surface of a lithium battery, for welding the lithium battery, the welding fixture includes a base 10 and a supporting plate 20 disposed on an upper side of the base 10, a receiving notch 11 is disposed in a middle portion of the base 10, the supporting plate 20 includes a connecting portion 21 connected to the base 10 and a supporting portion 22 disposed on an upper end of the connecting portion 21, and the supporting portion 22 is perpendicularly connected to the connecting portion 21.
