[0017] The present application will be further described in detail below with reference to the drawings and examples. It can be understood that the specific examples described herein are only used to explain the related invention, and not to limit the invention. In addition, it should be noted that, for the convenience of description, only the parts related to the invention are shown in the drawings.

[0018] It should be noted that the examples in the present application and the features in the examples can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and examples.

[0019] Cylindrical buckle key battery, such as Figure 1 As shown, the arc-shaped telescopic fixed plate 2 is fixed on the front end face of the battery body 1;

[0020] As shown in Figure 1 and Figure 2 The plate B 22 on the telescopic fixed plate 2 is inserted into the plate A 21 by a plurality of compression springs 3, and the plate B 22 can move in the plate A 21 to realize telescoping;

[0021] As shown in Figure 2 andFigure 4 As shown, a through hole 211 is provided on the plate A21, and a buckling protrusion is provided on the inner end surface of the through hole 211. The buckling protrusion is a circular ring located on the inner wall of the through hole 211;

[0022] like Figure 2 、 Figure 3 As shown, the upper end face of the snap-fit ​​column 4 is provided with a snap-off plate 41, the lower end face of the snap-off plate 41 is fixedly connected to the snap-fit ​​column 4 through a connecting column, and the snap-fit ​​column 4 is snapped into the through hole 211 through the snap-fit ​​protrusion, and the lower end face of the snap-fit ​​column 4 passes through the through hole 211 and abuts against the plate B22.

[0023] The buckling post 4 is made of plastic material and is convenient for buckling into the through hole 211 .

[0024] When in use, the battery body 1 is turned over to the side where the telescopic fixing plate 2 is not provided and pressed into the battery placement slot, and then the battery is manually flipped over so that the snap-fitting column 4 on the telescopic fixing plate 2 faces upward, and then the snap-off plate 41 is manually pulled to make the snap-fitting column 4 leave the through hole 211. At this time, under the action of the compression spring 3, plate B22 pushes plate B22 out of plate A21 until the end face of the suspended end of plate B22 abuts the inner wall of the battery placement slot. At this time, the snap-fitting column 4 is directly snapped into the through hole 211, and the snap-fitting column 4 is fixed by the snap-fitting protrusion in the through hole 211. At this time, the lower end face of the snap-fitting column 4 abuts the upper end face of plate B22, which increases the friction force of the relative movement of plate B22 and plate A21, that is, the end face of the telescopic fixing plate 2 abuts against the battery body placement slot, that is, the passive clamping and fixation of the battery body is achieved.

[0025] The above description is merely an illustration of the preferred embodiments of the present application and the technical principles employed. The scope of the invention herein is not limited to the technical solutions formed by the specific combination of the aforementioned technical features, but also encompasses other technical solutions formed by any combination of the aforementioned technical features or their equivalents without departing from the inventive concept.
