[0033] As Figure 1 , Figure 2 shown, the fixing mechanism 3 includes a tongue 31 and a locking tongue component 32. A plurality of tongues 31 are fixedly arranged at intervals on the outer sides of the front and rear walls of the upper cover plate 2, and locking tongue components 32 are correspondingly fixedly arranged near the tongues 31 on the outer sides of the front and rear walls of the lower cover plate 1. The tongue 31 can be locked and disengaged from the locking tongue component 32; the locking tongue component 32 includes a fixing plate 321, a chamber 322, a return spring 323, an adjusting plate 324, a convex block 325, a limiting frame 326 and a slot 327; the fixing plate 321 is fixed on the lower cover plate 1, a chamber 322 is formed inside the fixing plate 321, a return spring 323 is fixed on the inner wall of the chamber 322, an adjusting plate 324 is fixed at the free end of the return spring 323 corresponding to the position inside the chamber 322, a convex block 325 is fixed at the free end of the adjusting plate 324, a limiting frame 326 is fixed on the fixing plate 321 near one side of the convex block 325, and a slot 327 is formed on the bottom of the tongue 31 near one side of the convex block 325 for inserting the convex block 325; both ends of the adjusting plate 324 extend out of the limiting frame 326, and pressing the extending ends of the adjusting plate 324 can adjust the position of the convex block 325 on the Y-axis; inclined surfaces are formed at the bottom ends of the tongue 31, the convex block 325 and the slot 327.

[0034] As Figure 2 , Figure 3As shown, the lateral limiting mechanism 4 includes a first positioning component 41 and a second positioning component 42. The first positioning component 41 and the second positioning component 42 are arranged at intervals and mirror images of each other. The spacer block 13 is located between the first positioning component 41 and the second positioning component 42. The first positioning component 41 includes a sleeve 412, a slide bar 413, an arc-shaped clamping plate 414, and a tension spring 415. The sleeve 412 is fixed on the side wall of the upper cover plate 2 or the side wall of the lower cover plate 1 or the first partition plate 111 or the second partition plate 211. A slide bar 413 is slidably connected inside the sleeve 412. An arc-shaped clamping plate 414 is fixed at the free end of the slide bar 413. A tension spring 415 is sleeved on the barrel wall of the sleeve 412. The top end of the arc-shaped clamping plate 414 is provided with an inclined surface.

[0035] As Figure 3 , Figure 4 shown, the vertical limiting mechanism 5 includes a stopper 51, a movable rod 52, a backing plate 53, and a support spring 54. Movable rods 52 are slidably connected between two relatively arc-shaped clamping plates 414 at the top of the upper cover plate 2. A stopper 51 is fixed at the top end of the movable rod 52 corresponding to the top position of the upper cover plate 2. A backing plate 53 is fixed at the bottom end of the movable rod 52. Support springs 54 are sleeved on the movable rod 52 between the backing plate 53 and the upper cover plate 2. To facilitate the support and fixation of the lithium battery, the outer diameter of the stopper 51 is greater than the outer diameter of the movable rod 52. In this embodiment, the backing plates 53 are integrally connected along the Y-axis, and gaskets 531 are fixed on one side of the bottom ends of the backing plates 53 close to the spacer block 13.

[0036] During use, first, place the lithium battery inside the lower cover plate 1, and then insert the tongues 31 at the front and rear ends of the upper cover plate 2 into the inside of the limiting frame 326. Due to the telescopic characteristic of the return spring 323, the adjusting plate 324 is pushed to move inside the chamber 322, so that the adjusting plate 324 drives the convex block 325 to be embedded inside the slot 327 to fix the tongue 31, forcing the lower cover plate 1 and the upper cover plate 2 to be spliced together, and then fixing the lithium battery inside the lower cover plate 1 and the upper cover plate 2, improving the convenience of splicing and fixing. In addition, press the adjusting plate 324 to make the adjusting plate 324 drive the convex block 325 to re-enter the inside of the chamber 322 to release the limit, facilitating the separation of the lower cover plate 1 and the upper cover plate 2 and facilitating the replacement of the internal lithium battery.

[0037] Next, when the lower cover plate 1 and the upper cover plate 2 are spliced, due to the telescopic characteristic of the support spring 54, the backing plate 53 and the movable rod 52 are driven to slide, changing the position of the backing plate 53, so that the backing plate 53 fits with the top of the lithium battery at different heights, facilitating the positioning of the lithium battery, increasing the stability of the lithium battery, and preventing the lithium battery from sliding up and down.

[0038] Finally, by virtue of the telescopic property of the tension spring 415, the arc-shaped clamping plate 414 is pushed, causing the arc-shaped clamping plate 414 to drive the sliding rod 413 to slide along the inner wall of the sleeve 412, changing the distance between the two opposite arc-shaped clamping plates 414, facilitating the clamping and fixing of lithium batteries with different outer diameters, further improving the stability of the lithium battery between the lower cover plate 1 and the upper cover plate 2, preventing the phenomenon of left and right shaking of the lithium battery. In addition, the lithium battery is supported by the cushion block 13, leaving a gap between the bottom end of the lithium battery and the lower cover plate 1, and cooperating with the heat dissipation holes 12 to ensure the fluidity of the gas and enhance the heat dissipation effect.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
