[0029] The protractors 8, located on both sides of the center of the base pad 1, work together with the lifting assembly 2, leg support 11, and protractors 8. When the servo motor 211 is powered on, it drives the threaded screw 212 to rotate, which in turn drives the push slider 213 to push the lifting rod 22. This, in turn, drives the leg support plate 3 and the leg support 11 to rotate and adjust the lifting angle. The protractors 8 measure the angle between the base pad 1 and the leg support plate 3, thus achieving the effect of lifting the patient's lower limbs. They can also accurately measure the lifting angle to avoid it being too high or too low, ensuring that the treatment angle is within the optimal range.

[0030] Specifically, the lifting assembly 2 includes a drive group 21, a lifting rod 22, and a mounting block 23. The drive group 21 is fixedly installed on one side of the base pad 1, the lifting rod 22 is rotatably mounted on the top of the drive group 21, and the mounting block 23 is rotatably mounted on the top of the lifting rod 22.

[0031] In this embodiment, the drive unit 21 pushes the lifting rod 22, which in turn drives the leg support plate 3 and the leg support bracket 11 to rotate and adjust the lifting angle.

[0032] Specifically, the drive assembly 21 includes a servo motor 211, a threaded screw 212, and a push slider 213. The servo motor 211 is fixedly installed on one side of the base pad 1, the threaded screw 212 is fixedly installed at the output end of the servo motor 211, and the push slider 213 is threadedly connected to the surface of the threaded screw 212.

[0033] In this embodiment, after the servo motor 211 is powered on, it drives the threaded screw 212 to rotate, which in turn drives the push slider 213 to push the lifting rod 22.

[0034] Specifically, a sliding groove is provided in the middle of the top surface of the base pad 1, and the slider 213 is slidably disposed inside the sliding groove. One side of the bottom surface of the leg support plate 3 is hinged to the edge of the top surface of the base pad 1.

[0035] In this embodiment, the sliding groove facilitates the sliding of the slider 213.

[0036] Specifically, the positioning component 5 includes a positioning frame 51, a sliding pin 52, and an alloy spring 53. The positioning frame 51 is fixedly installed on one side of the fixed frame 4, the sliding pin 52 is slidably installed inside the positioning frame 51, and the alloy spring 53 is sleeved on the surface of the sliding pin 52.

[0037] In this embodiment, the positioning component 5 facilitates the quick assembly and disassembly of the combination leg 6 and the fixing frame 4.

[0038] Specifically, the two ends of the alloy spring 53 are fixedly connected to the positioning frame 51 and the fixing frame 4 respectively. The surfaces of the fixing frame 4 and the combined leg 6 are provided with limiting holes that are compatible with the sliding pin 52.

[0039] In this embodiment, the limiting hole facilitates the insertion of the sliding pin 52.

[0040] Specifically, one side of the clamping airbag 7 is connected to an inflation tube 9, and one end of the inflation tube 9 is connected to an inflatable airbag 10.

[0041] In this embodiment, pressing the inflatable balloon 10 inflates the clamping balloon 7 through the inflation tube 9, causing the clamping balloon 7 to clamp above the patient's foot, applying a slight upward traction force to the patient's foot while keeping the patient's foot upright.

[0042] Specifically, an exhaust pipe is fixedly installed in the middle of the top surface of the clamping airbag 7, and a plug is attached to the top of the exhaust pipe.

[0043] In this embodiment, the exhaust pipe facilitates the deflation of the airbag 7.

[0044] Specifically, there are four combination tripods 6 and clamping airbags 7, which are arranged in two symmetrical groups.

[0045] In this implementation scheme, the four combined footrests 6 and the clamping airbags 7 facilitate clamping the patient's feet.

[0046] Specifically, an anti-slip pad is fixedly installed on the bottom surface of the base pad 1, and an anti-slip groove is opened on the bottom surface of the anti-slip pad.

[0047] In this embodiment, the anti-slip pad prevents the base pad 1 from slipping.

[0048] The working principle and usage process of this utility model: After the servo motor 211 is powered on, it drives the threaded screw 212 to rotate, which drives the push slider 213 to push the lifting rod 22, thereby driving the leg support plate 3 and the leg support frame 11 to rotate and adjust the lifting angle. The protractor 8 measures the angle between the base pad 1 and the leg support plate 3. When the patient's lower limb is raised, the lifting angle can be accurately measured to avoid being too high or too low and to ensure that the treatment angle is within the optimal range.

[0049] Pull the sliding pin 52 outward to insert the combined footrest 6 into the fixed frame 4. Release the sliding pin 52. The reaction force of the alloy spring 53 causes the sliding pin 52 to be inserted into the fixed frame 4 and the combined footrest 6. At this time, the clamping airbag 7 is placed on the patient's foot.

[0050] Press the inflatable balloon 10 to inflate the clamping balloon 7 through the inflation tube 9, so that the clamping balloon 7 clamps the patient's foot above, applying a slight upward traction force to the patient's foot while keeping the patient's foot upright, avoiding the heel from being suspended in the air for a long time, which would cause the ankle joint to plantar flex and drop.
