[0051] The fixing assembly 6 also includes a third rotating rod 21, a second bevel gear set 22 and a third bevel gear set 23. The third rotating rod 21 is laterally arranged in the right-angle movable groove, and the third rotating rod 21 is rotatably connected to the inner side of the corresponding mounting plate 40. One end of the third rotating rod 21 extends to the outer side of the second rotating rod 19 and is provided with a second bevel gear set 22. The second rotating rod 19 drives the third rotating rod 21 to rotate through the second bevel gear set 22. The other end of the third rotating rod 21 extends to the outer side of the first rotating rod 17 located laterally inside the right-angle movable groove and is provided with a third bevel gear set 23. The third rotating rod 21 drives the first rotating rod 17 located laterally inside the right-angle movable groove to rotate through the third bevel gear set 23.

[0052] The fixing assembly 6 also includes a fixed concave plate 24, a movable plate 25, an extrusion arc plate 26 and a fixed sheet 27. The outer side of the movable concave plate 10 away from the rotating extrusion rod 11 is fixedly connected to the fixed concave plate 24. Both the fixed concave plate 24 and the movable concave plate 10 are provided with a first movable groove. The movable plate 25 is provided on the inner side of the first movable groove, and the movable plate 25 is clearance-matched with the inner sides of the fixed concave plate 24 and the movable concave plate 10 through the two first movable grooves. The movable plate 25 is located on the inner side of the fixed concave plate 24 away from the end of the movable concave plate 10 and is provided with a circular hole. The end of the movable plate 25 close to the rotating extrusion rod 11 is fixedly connected to the extrusion arc plate 26, and the extrusion arc plate 26 has the effect of extruding and limiting the rotating extrusion rod 11. The movable plate 25 is located on the inner side of the fixed concave plate 24 and is fixedly connected to the fixing sheet 27 at the top and bottom.

[0053] The fixing assembly 6 also includes a second fixing rod 28, a spring 29, a third fixing rod 30 and a limiting plate 31. The top and the bottom of the inner side of the fixed concave plate 24 are fixedly connected with the second fixing rod 28, and the second fixing rod 28 is slidably connected to the inner side of the fixing plate 27. The outer side of the second fixing rod 28 is provided with a spring 29, the spring 29 is located between the fixing plate 27 and the fixed concave plate 24, and the two ends of the spring 29 are fixedly connected to the fixing plate 27 and the fixed concave plate 24 respectively.

[0054] Specifically: after the conduit passes through the inner side of the flow port opened in the fixed plate 8, the second rotating rod 19 can be driven to rotate by turning on the first motor 18, so that the first rotating rod 17 located on the vertical inner side of the right-angle movable groove can be driven to rotate through the setting of the first bevel gear set 20, and the third rotating rod 21 can be driven to rotate synchronously through the setting of the second bevel gear set 22, and the first rotating rod 17 located on the lateral inner side of the right-angle movable groove can be driven to rotate synchronously through the setting of the third bevel gear set 23;

[0055] When the two first rotating rods 17 rotate, the driving gear 16 can be driven to rotate synchronously. At the same time, the meshing connection between the driving gear 16 and the two tooth plates 15 can drive the two tooth plates 15 to move toward one end close to each other and insert into the inner side of the opposite reserved groove, thereby driving the two movable concave plates 10 to move closer to each other.

[0056] When the movable concave plate 10 moves, it can drive the movable block 14 to move synchronously inside the fixed groove plate 12. The sliding connection between the first fixed rod 13 and the movable block 14 can connect and support the movable concave plate 10, and can also guide the moving path of the movable concave plate 10.

[0057] When the two movable concave plates 10 move toward one end close to the outer side of the catheter, the inner side of the movable concave plates 10 connected with the rotating extrusion rods 11 can be rotated to be close to the outer side of the catheter. At this time, the outer side of the catheter can be clamped by the four rotating extrusion rods 11.

[0058] At the same time, the elastic setting of the spring 29 can push the fixed sheet 27 to move toward one end of the rotating extrusion rod 11, thereby driving the movable plate 25 fixedly connected to the fixed sheet 27 to move toward one end of the rotating extrusion rod 11, and the movable plate 25 drives the extrusion arc plate 26 to fit the outer side of the rotating extrusion rod 11. The extrusion arc plate 26 cooperates with the extrusion limiter on the outer side of the rotating extrusion rod 11 to limit the rotation effect of the rotating extrusion rod 11, thereby achieving a fixing effect on the catheter.

[0059] When the position of the catheter needs to be adjusted, the circular hole of the movable plate 25 can be pulled to drive the movable plate 25 to move toward the end away from the rotating extrusion rod 11. At this time, the movable plate 25 will drive the extrusion arc plate 26 to break away from the extrusion fit with the rotating extrusion rod 11, and at the same time drive the two fixing plates 27 to slide outside the second fixing rod 28 and produce an extrusion effect on the spring 29.

[0060] The rotational position of the third fixing rod 30 and the limiting plate 31 is located away from the center of the circle of the limiting plate 31. When the limiting groove opened on the top of the movable plate 25 moves to the end of the fixed concave plate 24 away from the movable concave plate 10, the limiting plate 31 can be rotated to the inner side of the limiting groove opened on the top of the movable plate 25, thereby fixing the position of the movable plate 25. At this time, the rotating extrusion rod 11 can be rotated inside the movable concave plate 10 due to the loss of the extrusion limiting cooperation of the extrusion arc plate 26, thereby directly dragging the catheter and achieving the effect of conveniently adjusting the position of the catheter.

[0061] The motors mentioned above are all motors with power-off self-locking capabilities, such as servo motors.
