[0011] Preferably, one end of the T-shaped slide plate is welded to a limiting plate, the inside of the T-shaped slide groove is slidably connected to a push plate, an adjustment plate is rotatably connected between the push plate and the T-shaped slide groove via a hinge seat, an electric push rod welded to the push plate is installed inside the T-shaped slide groove, and two limiting plates are symmetrically arranged about the central axis of the electric push rod.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. When the existing lithium battery is in use, the sealing plate and the battery shell are connected by a number of small screws, which makes disassembly and assembly more cumbersome and inconvenient, making it more inconvenient to repair it later. The utility model is provided with a support groove, a support plate and a positioning mechanism. Since the sealing plate and the battery shell are clamped by the positioning plate and the positioning groove under the action of the support spring, and the positioning plate and the battery shell are slidably connected by the push-pull frame and the movable groove, the positioning plate can be separated from the positioning groove by moving the push-pull frame downward. Since the sealing plate and the battery shell are slidably connected by the support plate and the support groove, the support plate can be separated from the support groove by pushing the sealing plate to one side, thereby facilitating the rapid separation between the sealing plate and the battery shell, making it easy to take out the lithium battery body, thereby facilitating rapid maintenance and improving the convenience of use;

[0014] 2.
