[0039] The lifting mechanism 8 includes a second guide rod 81, a first sliding frame 82, a first fixed frame 83, a cylinder 84, a second guide frame 85, a connecting block 86, a third connecting rod 87 and a limiting frame 88. Two second guide frames 85 are connected to the left side of the bottom of the fixed plate 2 by welding. Two groups of second guide rods 81 are connected to the left side of the two second guide frames 85 by welding. One group of second guide rods 81 consists of two second guide rods 81. The two groups of second guide rods 81 are arranged in a left-right symmetrical manner. The first sliding frame 82 is slidably connected between the two second guide rods 81 in the two groups.

Then the medical staff places the patient's legs that need to be fixed between the two clamping blocks 74 on both sides. Initially, the first spring 75 is in a stretched state. Then the cylinder 84 is started to contract. The telescopic part of the cylinder 84 drives the third connecting rod 87 to move rightward through the connecting block 86. The third connecting rod 87 then drives the first sliding frame 82 on the right side to move upward. The first sliding frame 82 on the right side then drives the two fixed frames 71 to move upward. The two fixed frames 71 respectively drive the second fixing blocks 72 therein. The guide rod 73, the clamping block 74 and the first spring 75 move upward, and at the same time, the two fixed frames 71 respectively drive the second connecting rod 78 and the lever 77 to move upward through the clamping blocks 74, and then the lever 77 is disengaged from the limiting frame 88 on the right side. Under the action of the first spring 75 returning to its original position, the two first springs 75 on both sides respectively drive the two clamping blocks 74 on the same side to move in a direction close to each other and clamp the patient's legs. Then, when the two clamping blocks 74 on the same side move in a direction close to each other, the two second connecting rods 78 on the same side respectively drive the two levers 77 on the same side to move downward. At the same time, when the two fixed frames 71 move upward, Under the action of the movement, the two fixed frames 71 will lift the patient's legs respectively. When the patient's legs are clamped and lifted, the cylinder 84 is closed to clamp and lift the patient's legs. When the patient's legs need to be lowered and released, the cylinder 84 is started to extend, and the telescopic part of the cylinder 84 drives the third connecting rod 87 to move to the left through the connecting block 86. The third connecting rod 87 then drives the first sliding frame 82 on the right side to move downward, and the first sliding frame 82 on the right side then drives the two fixed frames 71 to move downward, and the two fixed frames 71 respectively drive the first guide rod 73 and the clamping block 74 and the first spring 75 to move upward through the second fixed block 72 therein.

[0043] When the two fixed frames 71 move upward, the threaded rod 92, the third guide rod 93 and the second sliding frame 94 will be driven to move upward through the second fixed frame 91. When the two clamping blocks 74 on both sides clamp the patient's legs respectively and the tightness needs to be adjusted, the medical staff rotates the threaded rod 92. Under the action of the threaded cooperation between the threaded rod 92 and the second fixed frame 91, the threaded rod 92 drives the second sliding frame 94 to move upward, and the second sliding frame 94 then drives the two levers 77 on both sides to move upward. The two levers 77 on both sides respectively drive the two clamping blocks 74 on the same side to move away from each other through the two second connecting rods 78 on the same side and gradually loosen the patient's legs. When it is necessary to clamp the patient's legs, the threaded rod 92 is rotated in the opposite direction, and the threaded rod 92 drives the second sliding frame 94 to move downward.
