[0028] As shown in the figure, the lifting assembly 5 includes a first slide rail 17 fixedly connected to the base 1. A first screw 18 is rotatably connected inside the first slide rail 17. A first adjustment knob 19 is fixedly connected to the upper end of the first screw 18. Rotating the first adjustment knob 19 can drive the first screw 18 to rotate, thereby driving the moving assembly 6 to move along the first slide rail 17, and the height of the clamping assembly 8 can be adjusted.

[0029] As shown in the figure, the moving component 6 includes a second slide rail 25. The rear side of the second slide rail 25 is slidably connected to the first slide rail 17 and threadedly connected to the first screw 18.

[0030] As shown in the figure, the adjustment component 7 includes a third slide rail 29, with a first slider 28 fixedly connected to the upper end of the third slide rail 29.

[0032] Working Principle: During use, the universal wheels 2 facilitate movement of the device. The lifting assembly 5 and the moving assembly 6 adjust the position of the clamping assembly 8. Specifically, rotating the first adjustment knob 19 rotates the first screw 18, which in turn moves the moving assembly 6 along the first slide rail 17, adjusting the height of the clamping assembly 8. Rotating the second adjustment knob 27 rotates the second screw 26, which in turn moves the adjustment assembly 7 along the second slide rail 25 via the first slider 28, adjusting the left and right positions of the clamping assembly 8. The adjustment assembly 7 also adjusts the spacing between the clamping assemblies 8. Specifically, when the clamping assembly 8 is moved to both sides of the knee joint to be cooled, rotating the third adjustment knob 32 rotates the bidirectional screw 31. The movement allows the arc-shaped clamp 30 to move closer to the third slide rail 29 via the second slider 33, thereby clamping the knee joint. The heat exchange box 3 contains an ice-water mixture, and the heat exchange tank 12 contains coolant. The ice-water mixture can cool the coolant. The circulating liquid supply component can pump the coolant into multiple heat exchange tubes 34. Specifically, the water pump 15 draws the coolant from the heat exchange tank 12 through the first connecting pipe 14, pumps it through the pumping pipe 16 into the corresponding third connecting pipe 36, then through the second connecting pipe 35 into the heat exchange tube 34, then through the corresponding second connecting pipe 35 and third connecting pipe 36 into the return pipe 13, and finally returns to the heat exchange tank 12. The heat is transferred through the heat-conducting pad 37, thereby cooling the knee joint.
