Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved by the present application more clear, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

It will be understood that when an element is referred to as being "mounted" or "disposed" on another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

In the description of the present application, the meaning of "a plurality" is two or more, unless explicitly defined otherwise. The meaning of "a number" is one or more than one unless specifically defined otherwise.

In the description of the present application, it should be understood that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships that are based on the orientation or positional relationships shown in the drawings, merely to facilitate description of the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the present application.

In the description of the present application, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communicated with the inside of two elements or the interaction relationship of the two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be.

The utility model is further described below with reference to the accompanying drawings.

According to the illustration in fig. 1: the utility model provides a lithium battery shell structure, which comprises: including casing 1, casing 2 under the lithium cell on the lithium cell, casing 2 top is equipped with two slots 5 under the lithium cell, casing 1 bottom is equipped with slot 5 matched with inserted block 6 on the lithium cell, inserted block 6 one side is equipped with spacing groove 7, slot 5 one side is equipped with recess 8, recess 8 sliding connection has stopper 9, be equipped with guiding mechanism between stopper 9 and the recess 8, casing 2 both sides are equipped with the screw hole 10 with recess 8 intercommunication respectively under the lithium cell, screw hole 10 threaded connection has threaded rod 11, threaded rod 11 one end rotates with stopper 9 to be connected, and the other end wears to establish screw hole 10 and extends to casing 2 external connection has knob 12 under the lithium cell.
