[0002] Orthopedics is a professional branch of medicine, which mainly studies and treats diseases related to the musculoskeletal system, such as bones, joints, muscles, and ligaments. In hospital orthopedic care, a fixed brace is needed to fix the leg after surgery to avoid secondary injury. For patients with leg fractures, the leg needs to be propped up to facilitate the recovery of the leg.
[0003] When treating a patient with a leg injury, the patient's leg needs to be raised and fixed by a fixed bracket to avoid secondary injury. When adjusting the existing fixed bracket, it is necessary to pull the insertion rod to disengage the connection with the moving rod, and then move the connecting rod to drive the fixed bracket to move, so that the fixed position of the patient's leg changes. After the adjustment is completed, the insertion rod is inserted into the slot of the moving rod to complete the position limiting of the fixed bracket. However, this adjustment method has a fixed adjustment distance during operation, which has large limitations and is not convenient for fine adjustment of the fixed bracket. Utility Model Content

[0013] Compared with the prior art, the advantageous effects of the easily adjustable fixed bracket are as follows: by rotating the handle on one side of the large gear, the large gear is driven to mesh with the driven gear, and the driven gear will drive the bidirectional threaded rod and the threaded block to perform threaded transmission, so that the threaded block moves, and when the two sets of connecting rods rotate, the movable plate will also be driven to move, and the large gear can drive the driven gear to accelerate, so that the movable plate can be quickly moved to the desired position, and the second threaded rod and the movable plate are driven to perform threaded transmission by rotating the magnet block, and the toggle block will squeeze the two sets of toggle rods to rotate the toggle rods, and when the toggle rods rotate, the limit block will be moved upward through the movable groove, and when the limit block is disengaged from the limit on the rotating plate, the rotating plate can be rotated and unfolded, and when the rotating plate made of magnetic conductive material contacts the magnet block, it will be attracted to it, and at this time, the patient's legs can be conveniently put into the bracket.
[0014] 1. When treating patients with leg injuries, it is necessary to lift and fix the patient's legs through a fixed bracket to avoid secondary injuries. When the patient's legs are not yet placed in the fixed bracket, in order to quickly adjust the movable plate, the handle on one side of the large gear is turned to drive the large gear and the driven gear to engage. The driven gear will drive the two-way threaded rod and the threaded block to perform threaded transmission to move the threaded block. The two sets of relatively moving threaded blocks will drive the two sets of connecting rods to rotate, so that the movable plate also moves. The movable plate can be guided and limited by the bracket body. Since the number of teeth on the large gear is more than that of the driven gear, the driven gear can be driven to accelerate the movement, so that the movable plate can be quickly moved to the desired position. In this way, the above operation can facilitate the fine adjustment of the position of the fixed bracket.
[0015] 2. When treating patients with leg injuries, it is necessary to lift and fix the patient's legs through a fixed bracket to avoid secondary injury. When the patient's legs are placed in the bracket, the magnet block can be rotated to drive the second threaded rod and the movable plate to perform threaded transmission. The second threaded rod can drive the toggle block to move downward, and the toggle block will squeeze the two sets of toggle rods to rotate the toggle rods. When the toggle rods rotate, they will move the limit blocks upward through the movable grooves. When the limit blocks move, they will squeeze the springs at the top. When the limit blocks are out of the limit on the rotating plate, the rotating plate can be rotated and unfolded. When the rotating plate made of magnetic conductive material contacts the magnet block, it will be attracted to it. At this time, the patient's legs can be conveniently sent into the bracket. In this way, the above operations can facilitate the placement of the patient's legs into the fixed bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figure 1-Figure 3 The utility model provides a technical solution: a fixed bracket that is easy to adjust, comprising: a bracket body 1 and a second threaded rod 14, a movable plate 2 is slidably connected to the outer side of the bracket body 1, and a sliding groove matching the bracket body 1 is provided inside the movable plate 2, a bracket 3 is fixedly connected to the bottom of the movable plate 2, and a fixed rod 4 is threadedly connected to the bottom of the bracket body 1,
[0023] The top of the bracket body 1 is movably connected with a bidirectional threaded rod 5 through a bearing, the outer side of the bidirectional threaded rod 5 is threadedly connected with a threaded block 6, the bottom of the threaded block 6 is movably connected with a connecting rod 7 through a rotating shaft, both ends of the bidirectional threaded rod 5 are fixedly connected with a driven gear 8, the outer side of the driven gear 8 is meshed with a small gear 9, the outer side of the driven gear 8 on the side of the top of the bracket body 1 away from the small gear 9 is meshed with a large gear 10, and one side of the small gear 9 and the large gear 10 are fixedly connected with a handle; the side of the bracket body 1 close to the driven gear 8 is movably connected with a first threaded rod 11 through a bearing, and the outer side of the first threaded rod 11 is threadedly connected with a connecting plate 12; the top of the connecting plate 12 is fixedly connected with a pressing block 13, and the bottom of the connecting rod 7 is movably connected with the moving plate 2 through a rotating shaft; a moving groove matching the threaded block 6 is provided at the top of the bracket body 1, and the threaded block 6 is slidably connected to the moving groove, the bidirectional threaded rod 5 and the threaded block 6 constitute a threaded transmission structure, and the threaded block 6 constitutes a rotating structure with the connecting rod 7 through the rotating shaft.
[0024] In specific implementation, when treating a patient with a leg injury, it is necessary to lift and fix the patient's leg through a fixed bracket to avoid secondary injury. When the patient's leg is not yet placed in the fixed bracket, in order to quickly adjust the movable plate 2, by turning the handle on one side of the large gear 10, the large gear 10 is driven to engage with the driven gear 8, and the driven gear 8 will drive the two-way threaded rod 5 and the threaded block 6 to perform threaded transmission, so that the threaded block 6 moves, and the two sets of relatively moving threaded blocks 6 will drive the two sets of connecting rods 7 to rotate, so that the movable plate 2 also moves, and the movable plate 2 can be guided and limited by the bracket body 1. Since the number of teeth of the large gear 10 is more than that of the driven gear 8, the driven gear 8 can be driven to accelerate the movement, so that the movable plate 2 can be quickly moved to the desired position;
[0025] When the patient's legs are on the bracket 3 at the bottom of the movable plate 2, the weight on the movable plate 2 will increase. At this time, the handle on one side of the pinion 9 can be rotated. When the pinion 9 is meshed with the driven gear 8, since the number of teeth is smaller than that of the driven gear 8, the driven gear 8 will be driven to perform a deceleration motion. At the same time, the force required to rotate the pinion 9 will be reduced, and the pinion 9 can be rotated more easily. Since it is a deceleration motion, the position of the movable plate 2 can be adjusted more accurately according to the needs of the patient. After the adjustment is completed, the first threaded rod 11 and the connecting plate 12 can be rotated for threaded transmission. The plane on one side of the connecting plate 12 is close to the bracket body 1, so it will not rotate. The connecting plate 12 can drive the pressing block 13 to contact with the driven gear 8, so that the friction force increases when the driven gear 8 rotates, thereby limiting the driven gear 8 to prevent the driven gear 8 from rotating when the handle is accidentally touched, so that the position of the movable plate 2 changes. In this way, the above operation can facilitate the fine adjustment of the position of the fixed bracket.
[0026] See also Figure 1 , Figure 2 and Figure 4 The inner thread of the movable plate 2 is connected with a second threaded rod 14, the bottom of the second threaded rod 14 is fixedly connected with a magnet block 15, the top of the second threaded rod 14 is welded and fixed with a toggle block 16, and a toggle rod 17 is arranged on the outer side of the toggle block 16; both sides of the toggle rod 17 are movably connected with the movable plate 2 through a rotating shaft, one side of the toggle rod 17 is slidably connected with a limiting block 18, and the inside of the limiting block 18 is provided with a movable groove matching the toggle rod 17, the top of the limiting block 18 is fixedly connected with a spring 19, and the top of the spring 19 is fixedly connected with the movable plate 2; a rotating plate 20 is movably connected with a rotating plate 20 on one side of the bottom of the movable plate 2 near the limiting block 18 through a rotating shaft, and a sponge pad 21 is fixedly connected to the inner side of the rotating plate 20 and the bracket 3, a sliding groove matching the limiting block 18 is provided inside the movable plate 2, and the limiting block 18 is slidably connected with the sliding groove, the toggle rod 17 forms a rotating structure with the movable plate 2 through the rotating shaft, and the second threaded rod 14 and the movable plate 2 form a threaded transmission structure.
[0027] In specific implementation, when treating a patient with a leg injury, the patient's leg needs to be fixed by a fixed bracket to avoid secondary injury. When the patient's leg is placed in the bracket 3, the magnet block 15 can be rotated to drive the second threaded rod 14 and the movable plate 2 to perform threaded transmission. The second threaded rod 14 can drive the toggle block 16 to move downward, and the toggle block 16 will squeeze the two groups of toggle rods 17 to rotate the toggle rods 17. When the toggle rods 17 rotate, the limit blocks 18 will move upward through the movable grooves. When the limit blocks 18 move, they will squeeze the springs 19 at the top. When the limit blocks 18 are separated from the limit of the rotating plate 20, the rotating plate 20 can be rotated and unfolded. When the rotating plate 20 made of magnetic conductive material contacts the magnet block 15, it will be attracted to it. At this time, the patient's leg can be conveniently sent into the bracket 3.
[0028] After being placed in, the rotating plate 20 can be rotated to disengage from the attraction with the magnet block 15. After the rotating plate 20 and the bracket 3 are combined, the patient's legs will be limited. At this time, the magnet block 15 can be reversed to drive the toggle block 16 to disengage from the squeezing of the toggle rod 17. At this time, the spring 19 will be reset, pushing the limit block 18 down to one side of the rotating plate 20 to limit the rotating plate 20. At this time, the rotating plate 20 will not be able to rotate, and the limiting of the rotating plate 20 is completed. The sponge pad 21 inside the bracket 3 and the rotating plate 20 will reduce the pressure on the patient's legs. In this way, the patient's legs can be easily placed in the fixed bracket through the above operation.
[0029] To sum up: when using the easily adjustable fixed bracket, first insert the "C"-shaped groove at the bottom of the bracket body 1 into the brackets on both sides of the patient's bed, and then rotate the fixing rod 4 and the bracket body 1 for threaded transmission. The fixing rod 4 will squeeze the bracket of the bed and limit the fixed bracket. After the limiting is completed, the patient's legs can be placed in the bracket 3 to complete the fixation of the patient's legs. This is the feature of the easily adjustable fixed bracket.
