s1, through starting first motor 10, the second drive gear 11 of first motor 10 output rigid coupling begins to rotate this moment, drive two meshed first drive gears 8 and begin to rotate afterwards, two first drive gears 8 begin to rotate simultaneously this moment, the pivot pole 6 that drives inside rigid coupling begins to rotate, the circular gear 7 of the outside rigid coupling of pivot pole 6 begins to rotate this moment, it can drive meshed gear post 2 through circular gear 7 rotation and begin to upwards contract, thereby make unable adjustment base 1 and ground contactless, it is more stable when making to place.

S2, through pulling out gag lever post 17 backward, gag lever post 17 drops from supporting seat 13 inside this moment, and supporting seat 13 promotes supporting seat 13 downwards through the elasticity of the first spring 14 that the outside cup jointed this moment, and supporting seat 13 contacts with ground this moment to it is more stable when making unable adjustment base 1 place.

S3, through starting second motor 24, the threaded rod 26 of second motor 24 output rigid coupling begins to rotate this moment, drive outside threaded connection' S screw thread section of thick bamboo 27 upward movement afterwards, slide bar 35 through the outside rigid coupling of screw thread section of thick bamboo 27 slides in second spout board 34, make screw thread section of thick bamboo 27 can not rotate during the rebound, thereby ensured and stablized reciprocating, slide in first spout board 33 when screw thread section of thick bamboo 27 upward movement, adjust bed board 21 and rotate around movable rod 19 this moment, thereby will adjust bed board 21 jack-up and adjust inclination, make things convenient for the doctor to carry out ultrasonic inspection more.

S4, through pulling the pulling force area 30 outwards, the inspection bed board 28 of drive rigid coupling begins to move afterwards, inspection bed board 28 bottom rigid coupling slider 32 slides in sliding groove board 31 this moment to it is more stable when making inspection bed board 28 adjust length and remove, can carry out spacingly to the length that inspection bed board 28 stretched out through with screens pole 38 joint in screens hole 36, can ensure that the inseparabler of screens pole 38 card makes spacing work more stable through the second spring 39 that screens pole 38 outside cup joints.

The above examples only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
