Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy as the negative electrode material, and a non-aqueous electrolyte solution.

At this time, the two round rods 68 are manually moved so that the two round rods 68 move toward each other along the inside of the two first circular holes 62, so that the two round rods 68 drive the two arc plates 69 to move toward each other. When the two arc plates 69 move toward each other to fit or be close to the surface of the lithium battery, the inner wall of the second circular hole 63 coincides with the inner wall of any circular groove 610. At this time, the two latches 611 are manually moved so that the two latches 611 move to the first circular holes 62 inserted on both sides and the corresponding circular groove 610 to limit the two round rods 68, and then the two arc plates 69 are limited by adjusting to a position close to or fitting the surface of the lithium battery, so that personnel can limit lithium batteries of different sizes by adjusting the two arc plates 69, reduce the sliding or shaking of the lithium battery during the electrolyte filling process, and improve the convenience and stability of personnel fixing lithium batteries of different sizes.
[0029] Reference Figure 2 and Figure 3 As shown, this embodiment discloses that the adjacent sides of the two arc plates 69 are fixedly connected with a plurality of rubber strips 612, and the plurality of rubber strips 612 are arranged at equal distances.
