At this time, the clamping column 608 can leave the inside of the clamping hole 602, and then the connecting frame 4 can be rotated upward. At this time, the top of the lifting column 609 will follow the side of the connecting frame 4 away from the rotating frame 2 to make a circular motion upward, and then it can drive the side of the lifting column 609 away from the connecting frame 4 to move in the inside of the slide groove 601 in the direction away from the rotating frame 2. When it moves to the position where the patient's lower leg can be unfolded, the lifting column 609 can move in the direction away from the rotating frame 2.

When the leg is placed on the placement curved plate 707, the sliding rod 706 can be driven downward by gravity, thereby driving the limiting slide 705 to move downward, and then compressing the buffer spring 704. As the limiting slide 705 moves downward, the liquid in the receiving groove 703 can be pushed into the interior of the liquid storage tank 702 through the liquid passage 708. At this time, due to the liquid passage 708 The hole 8 is small. When the placement curved plate 707 moves upward, the limiting slide 705 can be used to move upward, and the liquid in the liquid storage tank 702 can flow into the interior of the receiving tank 703 through the liquid through groove 708, and then it can, so when the liquid passes through the liquid through groove 708, it can limit the speed of the limiting slide 705 moving downward and upward, thereby avoiding the vibration of the placement curved plate 707 due to the vibration of the buffer spring 704, and then it can play a buffering role and prevent the sliding rod 706 and the placement curved plate 707 from vibrating.

[0034] The traction mechanism 8 includes a sliding plate 801, which can provide an installation position. The sliding plate 801 is slidably connected to the outside of the connecting frame 4. The top of the sliding plate 801 is fixedly connected to a restraint belt 802, which can easily fix the foot. The side of the sliding plate 801 away from the rotating frame 2 is fixedly connected to a pull rope 803, and the pull rope 803 plays a connecting role. The end of the pull rope 803 away from the rotating frame 2 is detachably connected to a placement plate 804, and a gravity weight 805 is provided on the outside of the placement plate 804. The placement plate 804 can conveniently place the gravity weight 805. When the foot is placed inside the restraint belt 802, the pull rope 803 is straightened under the action of the placement plate 804 and the gravity weight 805, and the gravity is transmitted to the patient's foot through the pull rope 803 and the restraint belt 802, thereby playing a pulling role on the foot. If the pulling force is not enough or too much, gravity weights 805 of different weights can be added or reduced to change the pulling force.

[0035] Working principle: When the patient is tall, the connecting block 303 is first pulled toward the outside of the rotating frame 2, so that the locking rod 307 can slide on the tooth groove 309. When the locking rod 307 is pulled, the locking rod 307 can slide on the inclined surface, so that the locking rod 307 can be squeezed upward under the action of the pulling force, and then the limiting round block 306 can be driven to move upward, so that the installation groove 304 can be compressed. When the locking rod 307 passes over the inclined surface on the teeth of the tooth groove 309, the limiting round block 306 is driven to slide downward under the thrust of the installation groove 304, so that When the movable rod 302 needs to be retracted into the interior of the rotating frame 2, the locking rod 307 is first pulled upward, which can drive the limiting block 306 to move upward, and then the locking rod 307 can be moved out of the interior of the tooth groove 309, thereby releasing the locking rod 307 from the tooth groove 309. At this time, the connecting block 303 can be pushed toward the direction of the rotating frame 2, and then the movable rod 302 can be retracted into the interior of the rotating frame 2.

[0036] When the patient stretches his legs, he first rotates the rotating handle 507 to drive the rotating rod 504 to rotate. After the rotating rod 504 rotates, the torsion spring 506 is rotated, and the blocking block 505 is rotated into the cylindrical groove 503. At this time, the rotating frame 2 can be rotated upward, thereby driving the top of the support rod 509 to rotate upward and pulling the sliding block 508 to slide toward the connecting frame 4. After sliding to the inclination suitable for the patient, the rotating handle 507 is loosened to allow the torsion spring 506 to rotate. 06 can drive the rotating rod 504 to reverse, and then the blocking block 505 can be rotated out of the cylindrical groove 503, and then the blocking block 505 can be used to block the sliding block 508, so that the bottom of the support rod 509 will not slide, and then the top of the support rod 509 will not move downward, and then the rotating frame 2 can be supported. If the rotating frame 2 needs to be reset, the rotating handle 507 can be rotated again, and the rotating frame 2 can be slid downward, so as to push the sliding block 508 to reset, and the folding of the rotating frame 2 is completed.

[0037] When the rotating frame 2 is unfolded, in order to unfold the patient's lower leg, it is necessary to pull the pull ring 610 outward, which can drive the clamping column 608 to move away from the bottom plate 1, and drive the limiting circular plate 607 to move away from the bottom plate 1 through the clamping column 608, and then compress the push spring 606. At this time, the clamping column 608 can leave the inside of the clamping hole 602, and then the connecting frame 4 can be rotated upward. At this time, the top of the lifting column 609 will follow the side of the connecting frame 4 away from the rotating frame 2 to make a circular motion upward, and then it can drive the side of the lifting column 609 away from the connecting frame 4 to move in the direction away from the rotating frame 2 inside the slide groove 601. When it moves to a height that can lift the patient's lower leg, the pull ring is released. 610, at this time, under the reaction force of the push spring 606, the limiting circular plate 607 can be driven to move in the direction close to the bottom plate 1, and then the clamping column 608 can be driven to move in the direction close to the bottom plate 1, and then the fixing column 604 and the slider 603 can be stopped. At this time, the lifting column 609 will not move, and the lifting angle of the connecting frame 4 can be fixed, and the calf can be placed on the connecting frame 4. When the connecting frame 4 is rotated downward and fits into the bottom plate 1, the pull ring 610 is pulled in the direction of the bottom plate 1, and then the clamping column 608 and the clamping hole 602 can be released, so that the slider 603 can be moved in the direction of the rotating frame 2, and then the lifting column 609 can be driven to reset, thereby driving the connecting frame 4 to reset;

[0038] When the legs are placed on the placement curved plate 707, the sliding rod 706 can be driven downward by gravity to drive the limiting slide plate 705 to move downward, thereby compressing the buffer spring 704. As the limiting slide plate 705 moves downward, the liquid in the receiving tank 703 can be pushed into the interior of the liquid storage tank 702 through the liquid passage 708. At this time, due to the small holes in the liquid passage 708, when the placement curved plate 707 moves upward, the limiting slide plate 705 can be used to move upward, and the liquid in the liquid storage tank 702 can flow into the interior of the placement tank 703 through the liquid passage 708. Therefore, when the liquid passes through the liquid passage 708, the downward and upward speeds of the limiting slide plate 705 can be limited, thereby preventing the placement curved plate 707 from vibrating due to the vibration of the buffer spring 704, thereby playing a buffering role and preventing the sliding rod 706 and the placement curved plate 707 from vibrating.

[0039] When the foot is placed inside the restraint belt 802, the pull rope 803 is straightened under the action of the placement plate 804 and the gravity weight 805, and the gravity is transmitted to the patient's foot through the pull rope 803 and the restraint belt 802, thereby pulling the foot. If the pulling force is insufficient or too much, adding or reducing gravity weights 805 of different weights can change the pulling force.
