[0015] The present invention has the following beneficial effects:

[0016] (1) In the present invention, four sodium ion batteries are placed on the top of the carrying shell through the discharge holes, and the sodium ion batteries are pressed. The sodium ion batteries press the carrying shell downward, so that the sodium ion batteries enter the interior of the carrying shell. Multiple sodium ion batteries are arranged separately to prevent the sodium ion batteries from piling up together, which affects the heat dissipation effect of the sodium ion batteries during operation. The carrying shell drives the rotating plate to press downward, and the rotating plate drives the first slider to move along the outer wall of the first slider. The first slider drives the rotating rod to move, and the rotating rod drives the diamond plate along the outer wall of the first slider. The outer wall of the vertical rod moves upward, the diamond plate drives the connecting rod to move upward, the connecting rod drives the square shell to move upward, the square shell drives the moving plate to move upward, the moving plate drives the inclined block frame to move upward, and the inclined block frame will contact the bottom of the descending bearing shell during the upward movement of the inclined block frame, and the reaction force of the bearing shell will cause the inclined block frame to drive the moving plate to move toward the inside of the square shell. During the movement of the moving plate, the coolant inside the square shell enters the inside of the bent pipe, and the coolant enters the inside of the discharge shell through the bent pipe. The coolant is sprayed on the outer wall of the bottom end of the sodium ion battery through the discharge shell, thereby improving the heat dissipation effect of the sodium ion battery.

[0017] (2) In the present invention, the first return spring is elastically deformed, and the first return spring drives the movable plate to move, and the movable plate drives the inclined block frame to move. During the movement of the inclined block frame, the inclined block frame will come into contact with the outer wall of the sodium ion battery, and the coolant accumulated at the bottom of the sodium ion battery will be scraped off, so that the coolant is completely coated on the outer wall of the sodium ion battery, thereby improving the heat dissipation effect of the sodium ion battery during operation. When the inclined block frame moves to the top of the sodium ion battery, it is elastically deformed by the first return spring, and the two inclined block frames approach each other. At this time, because the bottom of the inclined block frame is provided with multiple protrusions, the sodium ion battery is stuck at the bottom of the inclined block frame, which can prevent the sodium ion battery from popping outward, thereby improving the stability of the sodium ion battery after installation.

[0018] (3) According to the present invention, when the first slider moves, the first slider drives the first rotating bar to move, and is limited by the second slide groove. The first rotating bar drives the second slider to move along the outer wall of the second slide groove. The second slider drives the fixed rod to move, the fixed rod drives the special-shaped shell to move, the special-shaped shell drives the sliding plate to move, the sliding plate drives the clamping frame to move, and the two clamping frames move closer to each other, thereby clamping the outer wall of the sodium ion battery to prevent the sodium ion battery from shaking during operation, thereby improving the stability of the sodium ion battery. When subjected to the reaction force of the sodium ion battery, the sodium ion battery drives the clamping frame to move in the opposite direction, the clamping frame drives the sliding plate to move, the sliding plate drives the second rotating bar to move, and is limited by the inner wall of the special-shaped shell. The second rotating bar drives the concave block to move upward along the inner wall of the special-shaped shell, the concave block drives the connecting plate to move upward, and the connecting plate drives the special-shaped clamping plate to move upward. During the process of moving upward, the special-shaped clamping plate will contact the bottom of the carrying shell, and press the bottom of the carrying shell upward, so that the process of the carrying shell carrying the sodium ion battery is more stable, thereby improving the stability of the sodium ion battery.
