A connecting block 13 is slidably installed on the slide groove 14. A support shaft 9 is rotatably connected to one side of the connecting block 13. An end of the support shaft 9 away from the connecting block 13 is rotatably connected to an upper mounting frame 6. An end of the upper mounting frame 6 away from the support shaft 9 is clamped with a lower mounting frame 3. The lower mounting frame 3 is arranged below the upper mounting frame 6. Multiple limiting mechanisms are clamped on both the upper mounting frame 6 and the lower mounting frame 3, and the limiting mechanisms are used to clamp the pipeline; The connection block 13 is provided with an adjustment mechanism, which includes a threaded shaft 25 and is used to adjust the angle of the support shaft 9 .

[0021] The pillar 2 is provided with a plurality of mounting holes 5, and the connecting sleeve 12 includes two mounting rings arranged up and down, which are sleeved on the pillar 2, and the two mounting rings are respectively fixedly connected to the clamping ring 10 and the chassis 11, and the two mounting rings are both inserted with mounting bolts 17, which pass through the mounting rings and the mounting holes 5 at the same time, and the two ends of the mounting bolts 17 are threadedly sleeved with mounting nuts 16. The blood bottle is placed between the clamping ring 10 and the chassis 11, and the connecting sleeve 12 is sleeved on the pillar 2, and the mounting bolts 17 are simultaneously inserted into the mounting rings and the mounting holes 5, so that the position of the connecting sleeve 12 on the pillar 2 can be fixed, and the mounting bolts 17 can be inserted into the mounting holes 5 at different positions, and the height position of the blood bottle can be adjusted.

[0022] The clamping ring 10 is provided with an opening 18, and an adjusting bolt 19 is threadedly inserted into the opening 18. One end of the adjusting bolt 19 is clamped with one side of the opening 18, and the other end of the adjusting bolt 19 is threadedly sleeved with an adjusting nut 20, which is arranged on the other side of the opening 18. The clamping ring 10 is provided with a structure having an opening 18, and the size of the opening 18 is adjusted by the adjusting bolt 19, so that blood bottles of different sizes can be clamped and fixed, and the adjusting nut 20 is rotated to change the position of the adjusting nut 20 relative to the adjusting bolt 19, and then the length of the adjusting bolt 19 inserted into the opening 18 can be changed, thereby adjusting the size of the opening 18 and adjusting the diameter of the circle formed by the clamping ring 10.

The U-shaped shaft limits the connection block 13 to prevent the connection block 13 from sliding off the cross beam 8, and the rubber sheet 15 plays a role in increasing friction. When the connection block 13 is clamped in the slide groove 14, the friction keeps the relative position stable.

[0024] The upper mounting frame 6 and the lower mounting frame 3 are both provided with arc grooves 22 on their surfaces, and a positioning hole 23 is also provided on one side of each arc groove 22. The arc grooves 22 and the positioning holes 23 are used for clamping the limiting mechanism.

The upper and lower positions are separately arranged and arranged in sequence, which can effectively prevent the pipes from being intertwined with each other and avoid a chaotic state.

[0025] The positioning mechanism includes an arc block 27 and an arc clamp 26. The arc clamp 26 is rotatably mounted on one end of the mounting bolt 17. The arc block 27 is clamped in the arc groove 22. A positioning shaft 28 is fixedly connected to one side of the arc block 27 where the arc clamp 26 is provided. The positioning shaft 28 is inserted in the positioning hole 23. When the pipeline is limited, the pipeline is placed on the arc block 27 and is clamped and fixed by the arc clamp 26. The entire arc block 27 is positioned and fixed by the positioning shaft 28 on one side. When installing, the positioning shaft 28 can be directly inserted into the positioning hole 23 from one side.

[0026] The adjustment mechanism includes a threaded shaft 25, an adjustment slot 24 is provided on the support shaft 9, a threaded sleeve 29 is movably connected to the adjustment slot 24 through a sliding shaft, the threaded shaft 25 is rotatably connected to the bottom of the connecting block 13, and the threaded shaft 25 is threaded through the threaded sleeve 29. When the angle of the support shaft 9 needs to be adjusted, one end of the position of the threaded shaft 25 is limited by the connecting block 13, and is also limited by the threaded sleeve 29. The threaded sleeve 29 is limited by the support shaft 9, so when the threaded shaft 25 is rotated, the position of the threaded sleeve 29 relative to the threaded shaft 25 can be adjusted, and then the rotation angle of the support shaft 9 can be changed.

[0027] The connecting block 13 is fixedly connected with a slider 21, which is slidably arranged on the slide groove 14. A protrusion 31 is fixedly installed below the connecting block 13, and the threaded shaft 25 is rotatably inserted into the protrusion 31.

[0028] An insertion hole is provided at one end of the upper mounting frame 6 away from the support shaft 9, and one end of the lower mounting frame 3 is inserted into the insertion hole for connection through a connecting shaft 30. The connecting shaft 30 is installed on the insertion hole to realize a detachable installation structure between the lower mounting frame 3 and the upper mounting frame 6.

[0029] The blood bottle used for surgery is directly placed on the mounting mechanism, and the bottom of the blood bottle is located on the chassis 11. The size of the clamp 10 can be adjusted as needed. The adjusting nut 20 is turned to adjust the size and position of the opening 18 so that the clamp 10 can be adjusted to meet the needs. The pipeline extending from the bottom of the blood bottle comes out through the hole, and other pipelines extending from the blood bottle can be mounted on the upper mounting frame 6 and the lower mounting frame 3 respectively. A plurality of arc grooves 22 are provided on the upper mounting frame 6 and the lower mounting frame 3. A limiting mechanism is installed on the arc groove 22. The limiting mechanism can fix the position of the pipeline, thereby effectively avoiding the problem of interlaced and messy pipelines and ensuring the normal progress of the operation.

[0030] The arc block 27 in the positioning mechanism is inserted into the arc groove 22, and the positioning shaft 28 on one side of the arc block 27 is inserted into the positioning hole 23 for fixation. The arc clamp 26 clamps and fixes the pipeline. The arc clamp 26 with an arc structure can clamp the pipeline well. The height of the lower mounting frame 3 and the upper mounting frame 6 can be adjusted by the support shaft 9. The support shaft 9 and the upper mounting frame 6 are rotatably connected. Under the action of gravity, when the angle of the support shaft 9 changes, the upper mounting frame 6 and the lower mounting frame 3 can maintain relative horizontal stability.

[0031] By rotating the threaded shaft 25, the position of the threaded sleeve 29 relative to the protrusion 31 can be changed. When the position of the threaded sleeve 29 changes, the threaded sleeve 29 will slide on the adjustment groove 24, and then the angle of the support shaft 9 can be changed, thereby changing the height position of the lower mounting frame 3 and the support shaft 9.

[0032] The position of the mounting mechanism relative to the support 2 is adjustable, and the connecting sleeve 12 can be moved up and down. The mounting bolt 17 is inserted through the mounting hole 5 and the mounting ring at the same time, and then the mounting bolt 17 is fixed by the mounting nut 16, so that the position of the connecting sleeve 12 can be fixed, and the height position for placing the blood bottle can be adjusted. The height position can be adjusted according to the needs of the operation to ensure that the operation process can be carried out smoothly.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
