After the height of the hanging bracket 13 is appropriate, the first locking bolt 9 is reversed to move it inward, and the extension rod 7 can be locked inside the support sleeve 6 again.

[0034] In summary, for this adjustable infusion rod, when a support-type infusion rod is needed, the threaded disc 4 can be inserted into the threaded sleeve 3 and rotated. Through screw transmission, the threaded disc 4 can be driven to move downward until the bottom surface of the baffle 16 fits against the top surface of the threaded sleeve 3. At this time, the support sleeve 6 can be assembled with the support platform 2. At this time, the hook 5 will be inserted into the storage groove 14, which will not affect the screw connection between the threaded disc 4 and the threaded sleeve 3. At this time, the five-wheel universal base 1 is pushed to move to the use position, and it can be used as a support-type infusion rod. When a hanging infusion rod is needed, the threaded disc 4 can be twisted to move it out of the threaded sleeve 3, and the support sleeve 6 can be detached from the support platform 2. Subsequently, the second locking bolt 25 is twisted to move its screw part out of the threaded hole 24, and then the assembly disc 12 can be detached from the assembly pin 11. At this time, the assembly disc 12 can be reversed and assembled with the assembly pin 11, and finally the assembly disc 12 is locked using the second locking bolt 25. Then, the hook 5 can be hung at a high place and can be used as a hanging infusion rod. At this time, the infusion rod can be adjusted according to the use requirements, and there is no need to purchase infusion rods of multiple specifications, which can reduce the purchase cost of the infusion rod. During the use of the infusion rod, the user can twist the first locking bolt 9 to move it away from the extension rod 7 to release the locking of the extension rod 7. Subsequently, the extension rod 7 is pulled to slide inside the support sleeve 6. After the height of the hanging bracket 13 is appropriate, the first locking bolt 9 is reversed to move it inward, and the extension rod 7 can be locked inside the support sleeve 6 again, which is convenient for adjusting the height of the infusion rod. Moreover, when the extension rod 7 slides inside the support sleeve 6, it can drive the roller 18 to slide inside the groove 19, which is convenient for limiting the movement of the extension rod 7 and making the extension rod 7 slide more stably inside the support sleeve 6.
