In use of the fixing and supporting device of this embodiment, when a medical staff presses the pressing bar 790, since the driven bar 1060 is connected to the first flange 830 via the connecting bar 1080, and thus the driven bar 1060 moves in accordance with the movement of the pressing bar 790, before the pressing bar 790 presses the first inclined surface 780, the end of the driven bar 790 first presses the second inclined surface 1120 to disengage the second ratchet teeth 1210 from the first ratchet teeth 1110, and the pressing bar 790 is continuously pressed, so that the end of the pressing bar 790 presses the first inclined surface 780 to disengage the second latch teeth 740 on the stopper 720 from the first latch teeth 560. After the pressing plate 570 is loosened, the second ratchet 1210 on the fixing block 1020 can abut against the first ratchet 1110 under the pushing of the third spring 1090, so that the limiting block 720 cannot move towards the end of the first sliding plate groove 770, and the second latch 740 cannot be disengaged from the first latch 560, so that the deformation of the upper clamping piece 210 and the lower clamping piece 220 in the using process is avoided, and the stability of the fixing and supporting device in the using process is improved better.

The first flange 830 is connected to the driven rod 1060 through the connecting rod 1080, so that when the pressing plate 570 is pressed, the second ratchet 1210 can be separated from the first ratchet 1110 before the pressing rod 790 is in contact with the first inclined surface 780, and thus, the separation of the second ratchet 1210 from the first ratchet 1110 is stably and conveniently achieved.

In summary, the above-mentioned embodiments are only preferred embodiments of the present invention, and all equivalent changes and modifications made in the claims of the present invention should be covered by the claims of the present invention.
