The intersection of the first air supply pipe 324 and the first hollow tube 321 is located between the first piston 323 and the left end wall of the first hollow tube 321.

[0091] When the first air supply pipe 324 ventilates the first hollow tube 321 , it will drive the first piston 323 to slide rightward, thereby driving the first slider 312 to slide rightward as well, so that the first rotation axis is close to the second rotation axis, so that the first connecting rod 311 and the second connecting rod 313 can rotate upward, so that the lifting plate 2 rises.

[0092] In this embodiment, please refer to Figure 1 Fig.10 The sliding power module further includes an air supply submodule for supplying air to the first air supply pipe 324, and the air supply submodule includes a second hollow tube 331, a second piston 332, a second sliding rod 333, an air outlet pipe 334, a one-way valve 335 and a first spring 336;

At this time, the first hollow tube 321 is connected with the external space through the first air supply pipe 324, the air outlet pipe 334, and the air release pipe 343. Since the lifting plate 2 and the supporting frame 301 have a certain weight, the slider will be in an unlocked state at this time, and the lifting plate 2 will descend.

[0119] In this embodiment, please refer to Figure 1 Fig.10 , the transfer vehicle further includes an insert block 302 and a socket 303;

[0120] The insert block 302 is fixedly mounted on the bottom end surface of the lifting plate 2 , and an insert hole 303 is formed on the upper end surface of the supporting frame 301 , into which the insert block 302 is inserted.

[0121] Since there are many departments in the hospital, the surgical instruments used are large and small. For example, dental drills are generally small in size. In order to ensure that the lifting plate 2 can be normally lifted and lowered in the carriage 1, there will be a gap between the lifting plate 2 and the inner wall of the carriage 1. Smaller surgical instruments may fall below the lifting plate 2 along the gap. The lifting plate 2 is disassembled through the connecting support frame 301 through the plug block 302 and the socket 303. When a surgical instrument falls, the lifting plate 2 can be removed to avoid the surgical instrument from being lost.

[0122] In this embodiment, please refer to Figure 1 Fig.10 , the lifting plate 2 includes at least two supporting plates 201;

[0123] Two adjacent support plates 201 are rotatably connected, and the rotation axis between the adjacent support plates 201 is perpendicular to the side wall of the carriage 1 .

[0124] By configuring the lifting plate 2 to be composed of a plurality of support plates 201 , when the lifting plate 2 is removed, the support plates 201 can be rotated so that the plurality of support plates 201 can be folded for easy removal.

[0125] In this embodiment, please refer to Figure 1 Fig.10 The bottom end surface of the carriage 1 is provided with a roller 101 for facilitating the movement of the carriage 1 .

[0126] By installing a roller 101 on each of the four corners of the outer bottom surface of the carriage 1, the transfer vehicle can be easily pushed.

[0127] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
