The left end of the reducer body 300 is provided with a first rotating shaft 310, and the right end of the reducer body 300 is provided with a second rotating shaft. The outer side of the reducer body 300 is provided with a plurality of first heat dissipation fins. The first protective shell 100 is arranged at both ends of the reducer body 300. The inner side of the first protective shell 100 is provided with a plurality of second heat dissipation fins 160. The first heat dissipation fins and the second heat dissipation fins 160 are evenly spaced in sequence. The second protective shell 200 is arranged at the upper end of the reducer body 300. The inner side of the second protective shell 200 is provided with a plurality of third heat dissipation fins 230. The third heat dissipation fins 230 and the first heat dissipation fins are evenly spaced in sequence.

[0021] Furthermore, the first protective shell 100 is provided with several first blowing pipes, the left end of the first blowing pipe is provided with a first connecting port 110, the left end of the first protective shell 100 is provided with a first wind cover 130, the first connecting port 110 is matched with the first wind cover 130, the first wind cover 130 is provided with a first air inlet 131, the right end of the first blowing pipe is provided with a second connecting port, the right end of the first protective shell 100 is provided with a second wind cover 140, the second connecting port is matched with the second wind cover 140, and the second wind cover 140 has a first air outlet 141.

[0022] Furthermore, a first cooling pipe 210 is provided at the upper end of the second protective shell 200. The first cooling pipe 210 is arranged in an S shape. One end of the first cooling pipe 210 is provided with a first water inlet 211, and the other end of the first cooling pipe 210 is provided with a first water outlet 212.

[0023] Furthermore, a first screw 320 is provided at both ends of the reducer body 300, and a first mounting hole 150 is provided at both ends of the first protective shell 100, the first mounting hole 150 corresponds one-to-one to the first screw 320, and a first nut 340 is provided on the first screw 320, and the first nut 340 matches the first screw 320. A first spring 360 is sleeved on the first screw 320, and the first spring 360 corresponds between the reducer body 300 and the first protective shell 100.

[0024] Furthermore, a second screw 330 is provided at the upper end of the reducer body 300, and second mounting holes 220 are provided at both ends of the second protective shell 200. The second mounting holes 220 correspond one-to-one to the second screw 330. The second screw 330 is provided with a second nut 350, and the second nut 350 matches the second screw 330.

[0025] Working principle: The first spring 360 is mounted on the first screw 320, and the first protective shell 100 is then set at both ends of the reducer body 300, with the first mounting hole 150 mounted on the first screw 320. The first protective shell 100 is then fixed with the first nut 340. The second heat dissipation fins 160 are inserted one by one between the first heat dissipation fins. The reducer body 300 dissipates heat through the first heat dissipation fins, and the second heat dissipation fins 160 absorb the heat from the first heat dissipation fins. The first air inlet 131 is connected to a hair dryer that blows air toward the first blowpipe, taking away the heat absorbed by the second heat sink and dissipating it through the first air outlet 141. At the same time, the first protective shell 100 can prevent the reducer body 300 from being hit, and the first spring 360 provides the first protective shell 100 with a buffering capacity to reduce damage caused by collisions.

[0026] The second protective housing 200 is positioned at the upper end of the reducer body 300, with the second mounting opening positioned over the second screw 330. The second protective housing 200 is then secured using the second nut 350. The third heat sink fins 230 are inserted one by one between the first heat sink fins at the upper end. The reducer body 300 dissipates heat through the first heat sink fins, and the third heat sink fins 230 absorb heat from the first heat sink fins. Cooling circulating water is introduced into the first water inlet 211, flows in an S-shaped pattern within the first cooling pipe 210, and flows out through the first water outlet 212, quickly removing heat. Since heat tends to flow upward, the second protective shell 200 uses cooling circulating water to reduce the temperature of the reducer body 300 more quickly. In addition, there is a risk of collision at both ends of the reducer body 300. The first spring 360 provides a buffer and provides air cooling to ensure that even if a slight collision occurs, water will not get wet on the reducer body 300, that is, the reducer body 300 will not be damaged.

[0027] It is worth mentioning that the technical features such as the reducer body 300 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial layout method of these technical features can be selected by conventional means in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated.

[0028] For those skilled in the art, it is still possible to modify the technical solutions described in the aforementioned embodiments, or to replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of protection of the present utility model.
