[0053] The use process of the present application is as follows: when the lithium battery body 3 needs to be cooled due to heat generation, the motor 31 is controlled to work, the motor 31 drives the second shaft 32 to rotate, the second shaft 32 drives the bevel gear 33 to rotate, the bevel gear 33 drives the bevel gear 34 to rotate, the bevel gear 34 drives the front shaft 8 to rotate, then under the action of the chain wheel 35 and the chain 36, the two shafts 8 can be rotated at the same time, the rotation of the two shafts 8 can make the four fan blades 9 on the outside rotate, then under the action of the mesh plate 5, the air outside can be sucked into the shell 4, then through the corrugated hose 11 into the air casing 10, and finally under the action of the multiple air outlets, the air can be blown on the lithium battery body 3, and under the action of the breathable mesh 12, the air in the plate frame 1 can flow when blowing, so that the heat dissipation can be realized;

[0054] The rotation of the second shaft 32 can also drive the worm 41 to rotate, the worm 41 drives the worm gear 42 and the front worm 37 to rotate, then under the action of the chain wheel 38 and the chain 39, the two worms 37 can be rotated at the same time, the rotation of the two worms 37 drives the four worm gears 40 to rotate, the rotation of the four worm gears 40 drives the four shafts 47 to rotate, the rotation of the four shafts 47 drives the four rotating discs 44 and the four protruding rods 45 to rotate, since the protruding rods 45 are movably arranged in the outer frame 46, the rotation of the four rotating discs 44 driven by the four protruding rods 45 can make the four outer frames 46 move up and down constantly, thereby making the air casing 10 move up and down constantly, so that the air can be blown evenly on the lithium battery body 3, so that the dead angle of heat dissipation can be avoided, and the quality of heat dissipation can be ensured;

[0055] When the efficiency of heat dissipation needs to be increased, the knob 30 is rotated to rotate the moving rod 26, so that the two clamping rods 27 change from vertical to horizontal. Then the knob 30 is pushed to move the moving rod 26, the protrusion 25 and the piston two 24 to the right, so that the two clamping rods 27 move into the box two 23 through the through slot two, and the spring 28 changes from stretched to compressed. Then the knob 30 is rotated to make the two clamping rods 27 vertical, and the left clamping rod 27 can abut against the inner wall of the box two 23. When the piston two 24 moves to the right, the air in the box two 23 can enter the two boxes one 15 through the two pipes one 22 under the action of the three-way pipe 29, so as to push the two pistons one 16, the two square rods 17, the two moving blocks 19 and the eight tooth plates 21 to move to the right. The moving block 19 can contact the right inner wall of the rotating shaft one 8. The movement of the eight tooth plates 21 can make the eight first gears 20 rotate, and then make the eight rotating rods 14 rotate, so that the plurality of fan blades 9 rotate, so as to adjust the inclination angle of the fan blades 9. Since the left clamping rod 27 abuts against the inner wall of the box two 23, even if the spring 28 is always in a compressed state, the piston two 24 cannot move to the left to reset, so that the movement of the piston one 16, the square rod 17, the moving block 19 and the tooth plate 21 can be avoided. When the angle is adjusted, the angle of the fan blades 9 can be prevented from changing randomly, so that the inclination angle of the fan blades 9 does not change when the fan blades 9 rotate. After the inclination angle is adjusted, greater wind force can be obtained at the same speed, so that the heat dissipation effect can be increased, and the lithium battery body 3 can be prevented from overheating.

[0056] The above is only the preferred embodiment of the present application, and any skilled person in the art can modify the above-described technical solutions or modify them into equivalent technical solutions. Therefore, any simple modification or equivalent replacement of the technical solutions according to the present application is within the scope of protection of the present application.
