However, the second threaded rod 405 is limited and guided in the guide groove 4032 by the guide slide 4051, so that the second screw hole 4042 drives the second threaded rod 405 to move up and down, thereby driving the top hook 4053 to be raised and lowered.

[0056] Specific usage and function of this embodiment: In the present invention, during transportation, the limit rod 2042 is driven to move by pulling the pull rod 2046 to disengage from the limit socket 202 at the top, and the device falls freely under the action of gravity. At the same time, the overall height of the device is reduced, so that the space occupied by the device in the medical vehicle is reduced during transportation, which is convenient for medical personnel to transport the device to the patient's location quickly and conveniently, and improves the mobility and response speed of medical services. Then, the pull rod 2046 is released, because the limit rod 2042 squeezes the tightening spring 2045 in the reset cavity 2044 through the connecting convex ring 2043 when moving, so that the tightening spring 2045 is produced. When the pressure is lost, the elastic force is released, thereby pushing the connecting convex ring 2043 to move, and the connecting convex ring 2043 drives the limiting plug rod 2042 to reset and insert it into the limiting plug hole 202 at the bottom, thereby limiting it to prevent the device from moving up and down due to bumps during transportation. After being transported to the patient's destination, the limiting plug rod 2042 is driven to move by pulling the pull rod 2046 to disengage from the limiting plug hole 202 at the bottom, and then the device is lifted to make it insert the limiting plug rod 2042 into the limiting plug hole 202 at the top, and then the purification liquid barrel 305 is placed on the bearing bracket 304, and then the handle 3021 is rotated to drive the first threaded rod 302 to move in the first screw hole 302. 011 is meshed and rotated, so that it can be meshed and moved through the first screw hole 3011. Under the setting of the bearing 3022, it will not drive the fixed arc frame 303 to rotate. When it moves to a certain extent, the purified liquid barrel 305 can be pressed and fixed.
