The limiting ring 11 is arranged in the annular limiting groove 12. The limiting ring 11 cooperates with the annular limiting groove 12 to improve the rotation stability of the liquid storage box 7 and the worm gear 2. A liquid adding tube 14 is fixedly passed through the top of the liquid storage box 7.

A rechargeable battery for powering the cooling fan 1004 and the micro suction pump 9 is fixedly provided on the mounting frame 1003.

[0025] When the reducer worm 3 drives the worm wheel 2 to rotate, the worm wheel 2 drives the liquid storage box 7 to rotate in the reducer housing 1 through the liquid inlet pipe 5 and the liquid outlet pipe 6. At the same time, a micro suction pump 9 is used to transport the coolant in the liquid storage box 7 to the cooling chamber 4 through the liquid inlet pipe 5. The cooling chamber 4 absorbs the heat generated by the rotation of the worm wheel 2 and the meshing friction with the worm 3, so as to dissipate heat and cool the worm wheel 2, thereby preventing the worm wheel 2 from being worn due to excessive temperature and affecting the meshing with the worm 3.
