[0044] The side wall of the leg support slider 2 is slidably connected with a leg binding structure, and the leg support slider 2 is rollingly connected with a bracket 5;
[0045] The bottom support 1 is rotatably connected with a direction adjustment structure, such as Figure 3 As shown, the direction adjustment structure includes a rotating disk 6 rotatably connected to the bottom support 1 and a docking support rod 7 fixedly connected to the rotating disk 6. Specifically, as shown in Figure 8 As shown, a sliding groove 28 is provided on the top of the bottom support 1, a second socket 29 is provided circumferentially on the sliding groove 28, the rotating disk 6 is rotatably connected to the sliding groove 28, and a third socket 30 corresponding to the second socket 29 is provided circumferentially on the rotating disk 6, and a latch 31 is detachably inserted between one of the second sockets 29 and the corresponding third socket 30;
[0046] Further, such as Figure 8 As shown, the direction adjustment structure also includes two limit rods 20 fixedly connected to the rotating disk 6. Fig. 9 As shown, the side of the bracket 5 close to the direction adjustment structure is fixedly connected with two docking ears 21 corresponding to the limit rods 20, and the docking ears 21 are slidably connected with the corresponding limit rods 20;
[0047] A longitudinal adjustment structure is rotatably connected to the docking support rod 7, and one side of the bracket 5 is mounted on the longitudinal adjustment structure;
[0048] Specifically, when the leg support slider 2 needs to be adjusted, the latch 31 is pulled out, and the medical staff holds the two limit rods 20 with both hands, and rotates the two limit rods 20 to drive the rotating disk 6, the longitudinal adjustment structure, the bracket 5 and the leg support slider 2 to rotate. After the adjustment is completed, the second socket 29 is aligned with the third socket 30 and the latch 31 is inserted to fix the rotating disk 6;
[0049] Further, such as Fig. 9 As shown, a first socket 14 is provided on the top of the docking support rod 7, and the longitudinal adjustment structure includes a plug rod 15, the bottom of the plug rod 15 is slidably inserted in the first socket 14, two limiting collars 16 are provided on the rod body of the plug rod 15, a threaded portion 17 is provided on the rod body of the plug rod 15, and the threaded portion 17 is located between the two limiting collars 16, and the bracket 5 is threadedly connected with the threaded portion 17;
[0050] Furthermore, a disc 18 is fixedly connected to the top of the insertion rod 15, and an adjusting rod 19 is rotatably connected to the eccentric portion of the top of the disc 18. The arrangement of the disc 18 can increase the surface area of the top of the insertion rod 15 and increase the rotation path of the adjusting rod 19 during rotation, so that medical staff can rotate it more easily.
[0051] Specifically, when the leg support slider 2 needs to be adjusted downward, the adjustment rod 19 is rotated, and then the insertion rod 15 is driven to rotate through the disc 18. The two limit rods 20 provided can limit the bracket 5 to prevent the bracket 5 from rotating together with the insertion rod 15. When the insertion rod 15 rotates, the bracket 5 moves downward under the action of the threaded engagement, thereby driving the leg support slider 2 to move downward;
[0052] When the leg support slider 2 needs to be adjusted upward, the adjustment rod 19 only needs to be rotated in the opposite direction.
[0053] Further, such as Figure 1-Figure 4 As shown, both sides of the leg support slider 2 are provided with sliding rails 22, and a plurality of sliding blocks 23 are slidably connected to the sliding rails 22 on the side away from the adjustment structure, and the tops of the plurality of sliding blocks 23 are fixedly connected with straps 24;
[0054] A plurality of rope locking sliders 25 corresponding to the sliding blocks 23 are slidably connected to the sliding rail 22 near the side of the adjustment structure. A gap 26 is set between the rope locking slider 25 and the leg supporting slider 2. The free end of the strap 24 passes through the gap 26 and extends outside. The plurality of rope locking sliders 25 are threadedly connected to the side of the adjustment structure near the side of the adjustment structure.

The sliding rail 22 is set so that the sliding block 23 and the rope locking slider 25 can be adjusted accordingly according to the fixed position of the leg.
[0055] Specifically, when in use, the patient's calf is placed on the support pad 4, the free end of the strap 24 is passed along the gap 26, and the strap 24 is pulled to make the strap 24 fit the patient's leg. At this time, the adjusting bolt 27 is rotated to make the end of the adjusting bolt 27 squeeze the strap 24, thereby fixing the strap 24 and the leg. The patient's leg can be supported by the set leg support slider 2, and the adjusting bolt 27 is set on the side close to the adjustment structure for easy adjustment by medical staff.
[0056] Further, such as Figure 1 , Figure 5-Figure 7 As shown, the leg support slider 2 is provided with a through groove 8, and guide parts 9 are arranged on both sides of the through groove 8. The top of the bracket 5 is rotatably connected with a shaft 10, and both ends of the shaft 10 are fixedly connected with rollers 11 corresponding to the guide parts 9. The rollers 11 are rollingly connected with the top of the inner wall of the corresponding guide part 9, and the leg support slider 2 is supported by the rollers 11. At the same time, when the leg support slider 2 moves, the rollers 11 roll along the top of the inner wall of the guide part 9, thereby reducing the friction of the leg support slider 2 when it moves, and reducing the strength required by the patient when performing leg varicose veins;
[0057] The bottom of the inner wall of the bracket 5 is rollingly connected with multiple groups of rolling balls 12, and the bottom of the leg support slider 2 is provided with multiple guide grooves 13 corresponding to each group of rolling balls 12. Each group of rolling balls 12 is rollingly connected with the top of the inner wall of the corresponding guide groove 13, and the bottom of the leg support slider 2 is further supported by the rolling balls 12. At the same time, when the leg support slider 2 moves, the rolling balls 12 roll along the top of the inner wall of the guide groove 13, thereby reducing the friction of the leg support slider 2 when it moves; a gap is left between the inner wall of the bracket 5 and the leg support slider 2, further reducing the friction of the leg support slider 2 when it moves.
[0058] Further, such as Fig.11 As shown, the two sides of the bracket 5 are fixedly connected with the bearing sub-plates 38 through the support rods, and the two bearing sub-plates 38 are rollingly connected with multiple groups of rolling balls 12 corresponding to the guide grooves 13, and each group of rolling balls 12 is rollingly connected with the top of the inner wall of the corresponding guide groove 13. The supporting effect on the bottom of the leg support slider 2 can be increased by setting the bearing sub-plates 38 and the rolling balls 12 rollingly connected to the bearing sub-plates 38;
[0059] Further, such as Figure 1 and Fig.12As shown, a clamping block 34 is slidably sleeved on the rod body of the docking support rod 7, and the same clamping bolt 35 is placed at both ends of the clamping block 34, one end of the clamping bolt 35 is abutted against one end of the clamping block 34, and the other end of the clamping bolt 35 is threadedly connected with a nut 36, and the nut 36 is abutted against the other end of the clamping block 34, and one side of the clamping block 34 is fixedly connected with a clamping block 37. When in use, the clamping block 34 is slid so that the bottom of the clamping block 37 contacts the upper surface of the side of the bed, and then the nut 36 is rotated. The rotating nut 36 applies pressure to one end of the clamping block 34, thereby clamping the clamping block 34 on the docking support rod 7. The provision of the clamping block 37 can improve the stability of the device when in use, and prevent the device from shaking as a whole when the patient performs varicose veins of the legs.
[0060] In summary, the workflow of the utility model is:
[0061] During installation, the insert block 33 is inserted into the corresponding fourth socket 32, thereby limiting and fixing the support pad 4;
[0062] The position of the leg support slider 2 is adjusted according to the body shape of different patients and the varicose height of the patient's legs. When adjusting the angle, the latch 31 is pulled out, and the medical staff holds the two limit rods 20 with both hands, and rotates the two limit rods 20 to drive the rotating disk 6, the longitudinal adjustment structure, the bracket 5 and the leg support slider 2 to rotate. After the adjustment is completed, the second socket 29 is aligned with the third socket 30 and the latch 31 is inserted to fix the rotating disk 6;
[0063] When the leg support slider 2 needs to be adjusted downward, the adjusting rod 19 is rotated, and then the insertion rod 15 is driven to rotate through the disc 18. The two limit rods 20 provided can limit the bracket 5 to prevent the bracket 5 from rotating together with the insertion rod 15. When the insertion rod 15 rotates, the bracket 5 moves downward under the action of the threaded engagement, thereby driving the leg support slider 2 to move downward;
[0064] When the leg support slider 2 needs to be adjusted upward, it is only necessary to rotate the adjustment rod 19 in the opposite direction;
[0065] After the adjustment is completed, the patient's calf is placed on the support pad 4, the free end of the strap 24 is passed along the gap 26, and the strap 24 is pulled to make the strap 24 fit the patient's leg. At this time, the adjusting bolt 27 is rotated to make the end of the adjusting bolt 27 squeeze the strap 24, thereby fixing the strap 24 and the leg. After fixation, the patient can perform varicose veins of the legs and conduct leg rehabilitation training.
