The inner walls of the opposite parts of the two adjustment and fixation components 35 are both fixedly connected with a protection component 36 and the two protection components 36 are located between the first arc-shaped support plate 31 and the second arc-shaped support plate 32;

[0030] First, rotate and open the arc-shaped support plate 31 in the fixed component 1 and the fixed component 2. Then, move the patient's leg between the arc-shaped support plate 31 and the arc-shaped support plate 32. At this time, the position and length can be adjusted through the four telescopic rods 2. After adjustment, fix the arc-shaped support plate 31 and the arc-shaped support plate 32. Then, under the action of the two adjusting and fixing components 35, make the two protective components 36 move towards each other, so as to move to fit the patient's leg. At this time, under the action of the protective component 36, the two adjusting and fixing components 35 will not cause harm to the patient when adjusting and fixing the patient's leg, thus playing a protective role.

[0031] As Figures 4 - 6 shown, a clamping plate 33 is fixedly connected to the right part of the upper surface of the right part of the arc-shaped support plate 32. The outer wall of the clamping plate 33 is clamped with the inner cavity of the right part of the arc-shaped support plate 31. A buckle 34 is rotatably connected to the right side of the clamping plate 33. The outer wall of the limiting rod on the left side of the upper part of the buckle 34 is slidably connected with the arc-shaped groove opened on the right side of the arc-shaped support plate 31;

[0032] When the arc-shaped support plate 31 and the arc-shaped support plate 32 are combined, the outer wall of the clamping plate 33 is clamped with the inner cavity of the right part of the arc-shaped support plate 31. At this time, by rotating the buckle 34, the buckle 34 can be rotated along the arc-shaped groove opened on the right side of the arc-shaped support plate 32 to the groove opened on the right side of the arc-shaped support plate 31, so that the arc-shaped support plate 31 and the arc-shaped support plate 32 are fixed together, which is convenient for quick operation and fixation.

[0033] The adjusting and fixing component 35 includes a rotating plate 351. The outer wall of the lower part of the rotating plate 351 is movably sleeved with the inner cavity of the central part of the upper part of the arc-shaped support plate 31.

Both the left and right sides of the two second connecting rods 357 are fixedly connected with fifth bevel gears 358;

[0034] By rotating the rotating plate 351, the bevel gear one 352 drives the bevel gear two 353 and the bevel gear three 355 to rotate under the action of the connecting rod one 354. Under the action of the two bevel gears three 355, the two bevel gears four 356 drive the two connecting rods two 357 to rotate simultaneously, so that the four threaded rods 3510 can be driven to rotate simultaneously, making the arc-shaped fixing plate 3511 more stable when moving, so that the force applied when fixing the patient's leg is uniform, thus achieving a better fixing effect.

[0035] The lower surfaces of the outer walls of the four bevel gears five 358 are all engaged with bevel gears six 359. The lower surfaces of the four bevel gears six 359 are all fixedly connected with threaded rods 3510. The upper parts of the outer walls of the four threaded rods 3510 are respectively movably sleeved in the inner cavity of the arc-shaped support plate one 31, and the lower parts of the outer walls of the four threaded rods 3510 are threadedly sleeved with arc-shaped fixing plates 3511;

[0036] Through the action of the four bevel gears five 358, the four threaded rods 3510 rotate simultaneously under the action of the four bevel gears six 359, so that the arc-shaped fixing plate 3511 moves downward, so as to facilitate adjustment and fixation according to the patient's leg condition. At the same time, since the inner walls of the arc-shaped support plate one 31 and the arc-shaped support plate two 32 are both provided with arc-shaped fixing plates 3511, it is possible to adjust and fix more flexibly according to the different leg conditions of the patient.

[0037] Such as Figure 7 、 Figure 8 As shown, a number of ventilation holes are provided on the outer wall of the middle arc-shaped plate of the arc-shaped fixing plate 3511. Arc-shaped ventilation holes are provided on the left and right sides of the middle arc-shaped plate of the arc-shaped fixing plate 3511, and the ventilation holes communicate with each other;

[0038] Since a number of ventilation holes are provided on the outer wall of the middle arc-shaped plate of the arc-shaped fixing plate 3511, the fixed part of the patient can be ensured to be ventilated during use.

[0039] The protection component 36 includes an arc-shaped connecting plate 361. The outer wall of the arc-shaped connecting plate 361 is fixedly connected with the inner wall of the arc-shaped fixing plate 3511. The front, rear, left and right of the arc-shaped connecting plate 361 are fixedly connected with ventilation sponge pads 362. The upper surfaces of the left and right parts of the ventilation sponge pads 362 are respectively fixedly connected with the left and right sides of the middle arc-shaped plate of the arc-shaped fixing plate 3511;

[0040] Through the action of the ventilation sponge pads 362, the fixed part of the patient can be ventilated, and at the same time, it can also play a role in improving comfort.

[0041] An arc-shaped rubber pad 364 is fixedly connected to the inner cavity between the ventilation sponge pad 362 and the arc-shaped connecting plate 361, and a ventilation mesh wear-resistant layer 363 is fixedly connected to the outer wall of the ventilation sponge pad 362;

[0042] Through the action of the arc-shaped rubber pad 364, the arc-shaped fixing plate 3511 and the arc-shaped connecting plate 361 can have a certain buffer during fixation, so as to tightly fix the patient without causing damage to the patient.

[0043] The working principle of the present utility model: First, rotate and open the arc-shaped support plate 31 in the first fixing component 1 and the second fixing component 3. Then, move the patient's leg between the arc-shaped support plate 31 and the arc-shaped support plate 32. At this time, the position and length can be adjusted through the four telescopic rods 2. After adjustment, merge the arc-shaped support plate 31 and the arc-shaped support plate 32. At this time, the outer wall of the clamping plate 33 is clamped with the inner cavity of the right part of the arc-shaped support plate 31. By rotating the buckle 34, the buckle 34 can rotate along the arc-shaped groove opened on the right side of the arc-shaped support plate 32 into the groove opened on the right side of the arc-shaped support plate 31, so that the arc-shaped support plate 31 and the arc-shaped support plate 32 are fixed together. After fixation, by rotating the rotating plate 351, the first bevel gear 352 drives the second bevel gear 353 and the third bevel gear 355 to rotate under the action of the connecting rod 354. Under the action of the two third bevel gears 355, the two fourth bevel gears 356 drive the two connecting rods 357 to rotate at the same time, so that the four fifth bevel gears 358 rotate at the same time. Through the action of the four fifth bevel gears 358, the four threaded rods 3510 rotate at the same time under the action of the four sixth bevel gears 359, so that the arc-shaped fixing plate 3511 moves downward, so as to facilitate adjustment and fixation according to the patient's leg condition. At the same time, since the inner walls of the arc-shaped support plate 31 and the arc-shaped support plate 32 are both provided with the arc-shaped fixing plate 3511, it can be adjusted and fixed more flexibly according to the different leg conditions of the patient. During tight fixation, through the action of the arc-shaped rubber pad 364, the arc-shaped fixing plate 3511 and the arc-shaped connecting plate 361 can have a certain buffer during fixation, so as to tightly fix the patient without causing damage to the patient, thus playing a protective role.
