[0025] Specifically, the electric push rod 2 drives the moving plate 3 to move up and down. When the moving plate 3 moves up and down, it drives the first transmission rod 4 to move synchronously. When the first transmission rod 4 moves up and down, it drives the first transmission plate 5 to rotate. When the first transmission plate 5 rotates, it drives the first rotating shaft 6 to rotate. When the first rotating shaft 6 rotates, it drives the second transmission plate 7 to rotate. Then the second rotating shaft 9 rotates with the rotation of the first transmission plate 5. When the second rotating shaft 9 rotates, it drives the third transmission plate 10 to rotate. When the third transmission plate 10 rotates, it drives the second transmission rod 11 to move up and down. When the second transmission rod 11 moves up and down, it drives the fixed block 12 to move synchronously. Finally, the purpose of controlling the up and down movement of the worktable 13 is achieved. If the patient has any discomfort, it can be stopped in time, thereby avoiding the patient from being strained due to excessive traction force.
[0026] Reference Figure 1 The fixing component includes a worktable 13, the lower surface of the worktable 13 is fixedly connected to the upper surface of the fixing block 12, and a limit block 14 is fixedly connected to the upper surface of the middle part of the worktable 13.
[0027] Specifically, the fixing block 12 fixes the worktable 13 to the upper surface of the fixing block 12, and the worktable 13 fixes the limiting block 14 to the surface of the worktable 13.
[0028] Reference Figure 1 , Figure 3 and Figure 4 The inner wall of the limiting block 14 is fixedly connected to a first rotating column 15, and the outer wall of the first rotating column 15 is rotatably connected to a first rotating block 16; the inner wall of the limiting block 14 is rotatably connected to a second rotating column 17, and the upper surface of the second rotating column 17 is fixedly connected to a locking block 18; the upper surface of the locking block 18 is fixedly connected to a second rotating block 19; brackets 20 are provided on the upper surfaces of both the left and right sides of the worktable 13; a positioning block 21 is fixedly connected to the lower surface of the bracket 20, the outer wall of the positioning block 21 is located on the inner wall of the worktable 13, a connecting block 22 is fixedly connected to the outer wall of the bracket 20, and the lower surface of the connecting block 22 is located on the upper surface of the worktable 13; the outer wall of the first rotating block 16 is located on the inner wall of the connecting block 22;
[0029] Specifically, by rotating the second rotating block 19, the locking block 18 is driven to rotate. When the locking block 18 rotates, it will drive the second rotating column 17 to rotate. Then the locking block 18 separates from the first rotating block 16, and then the first rotating block 16 is pulled. At this time, the first rotating block 16 separates from the connecting block 22, and then the bracket 20 is lifted to separate the positioning block 21 from the limiting block 14. Finally, the purpose of quickly replacing and installing the bracket 20 is achieved, so that the bracket 20 can be replaced according to the different body types of patients.
[0030] Working Principle: When the traction frame is needed, firstly, the electric push rod 2 is activated to move the moving plate 3 up and down. As the moving plate 3 moves up and down under the influence of the electric push rod 2, it drives the first transmission rod 4 to move synchronously. When the first transmission rod 4 moves up and down under the influence of the moving plate 3, it drives the first transmission plate 5 to rotate around it. When the first transmission plate 5 rotates under the influence of the first transmission rod 4, it drives the first rotating shaft 6 to rotate. When the first rotating shaft 6 rotates under the influence of the first transmission plate 5, it drives the second transmission plate 7 to rotate around the fixed plate 8. At this time, the second rotating shaft 9 rotates under the influence of the first transmission plate 5. When the second rotating shaft 9 rotates under the influence of the first transmission plate 5, it drives the third transmission plate 10 to rotate around the second transmission rod 11. When the third transmission plate 10 rotates under the influence of the second rotating shaft 9, it drives the second transmission rod 11 to move up and down. When the second transmission rod 11 moves up and down under the influence of the third transmission plate 10, it drives the second transmission rod 11 to move up and down. The fixed block 12 moves synchronously, ultimately controlling the up and down movement of the worktable 13. This process provides uniform force, and can be stopped promptly if the patient experiences discomfort, thus preventing injury due to excessive traction. By rotating the second rotating block 19, the locking block 18 rotates. When the locking block 18 rotates under the influence of the second rotating block 19, it drives the second rotating column 17 to rotate inside the limiting block 14. At this time, the locking block 18 disengages from the surface of the first rotating block 16, causing the first rotating block 16 to rotate around the first rotating column 15. Then, the first rotating block 16 separates from the inner wall of the connecting block 22, lifting the bracket 20 upwards and causing the positioning block 21 to disengage from the limiting block 14. This achieves the goal of quickly replacing and installing the bracket 20, allowing for the replacement of the bracket 20 according to different patient sizes. An adjustable traction frame not only prevents injury due to excessive traction but also allows for the replacement of the bracket 20 according to different patient sizes.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
