[0068] The U-shaped plate 512 slides through the support plate 55, and a second threaded knob 513 is threadedly connected and penetrated through the bottom wall of the U-shaped plate 512;

[0069] One end of the second threaded knob 513 is rotatably connected to the bottom wall of the support plate 55;

[0070] A support plate 514 is fixed to a side of the bottom wall of the backing plate 55 close to the seat plate body 51 .

[0071] A first waist-shaped hole 14 communicating with the slide groove 6 is formed through the side wall of the crossbar 4 , and the first threaded column 53 is slidably installed in the first waist-shaped hole 14 .

[0072] In this embodiment, the seat plate assembly 5 is provided to facilitate the patient to sit upright, and the position of the seat plate assembly 5 can be adjusted, so that the patient can be examined in a comfortable sitting position. At the same time, the seat plate assembly 5 can be unfolded into a bed body, so that the patient can be examined in a conventional left-lying position, and its application range is wide. When it is necessary to adjust the position of the seat plate body 51, the threaded cap 54 is rotated so that the threaded cap 54 is separated from the side wall of the cross bar 4, and the seat plate body 51 can be smoothly pushed to move. After the seat plate body 51 is pushed to a suitable position, the threaded cap 54 is rotated in the opposite direction to make the threaded cap 54 fit tightly against the side wall of the cross bar 4 again, and the position adjustment of the seat plate body 51 is completed.

In this embodiment, the length of the seat plate body 51 and the back plate 55 is 60cm to 80cm, and the width is 50cm to 65cm.

[0073] The lifting mechanism includes a threaded sleeve 15, which is fixedly mounted on the bottom wall of the movable column 3, and a threaded rod 16 is screwed in the center of the threaded sleeve 15;

[0074] The top wall of the threaded rod 16 is rotatably connected to a limit plate 17, and the bottom end of the threaded rod 16 is connected to a driving motor 18;

When the extension length of the movable column 3 needs to be adjusted, the driving motor 18 is started, the driving motor 18 drives the threaded rod 16 to rotate, and the threaded rod 16 drives the movable column 3 to move up and down through the threaded sleeve 15, completing the adjustment of the movable column 3, and the limiting plate 17 is capable of preventing the threaded rod 16 from being separated from the threaded sleeve 15, causing the movable column 3 to fall off.

[0078] The semicircular plate 22 is rotatably mounted on the top of the side wall of the bottom column 1, and the cross bar 4 is fixed on one side of the semicircular plate 22. An arc-shaped through groove 24 is opened on the semicircular plate 22. A second threaded column 23 is fixed on the top of the side wall of the bottom column 1, and a nut 25 is screwed on the second threaded column 23.

[0079] In this embodiment, by providing the semicircular plate 22 in conjunction with the second threaded column 23 and the nut 25, the cross bar 4 can be deflected within a certain range, thereby controlling the deflection movement angle of the seat plate assembly 5 to meet different usage requirements.

[0084] In this embodiment, the support plate assembly 8 can support the patient's chin, thereby saving the patient's physical strength, and the position of the support plate assembly 8 can be adjusted to meet the needs of patients with different face shapes. When the position of the support plate assembly 8 needs to be adjusted, the third threaded knob 83 is rotated to separate the side wall of the third threaded knob 83 from the side wall of the movable column 3. At this time, the second slider 82 can move smoothly in the limiting groove 21, control the arc support plate 81 to rest on the patient's chin, and the third threaded knob 83 is rotated in the opposite direction to fix the position of the arc support plate 81.

[0089] The bidirectional screw 134 is rotatably mounted between the upper and lower walls of the mounting cavity 20, and the top end of the bidirectional screw 134 passes through the top wall of the mounting block 9 through a bearing and is fixed with a knob 135;

[0090] Arc grooves 136 are formed on the sides of the clamping plates 131 that are close to each other.

[0091] In this embodiment, the limit assembly 13 can fix the position of the guide wire after the digestive endoscope reaches the specified position, avoiding accidental pulling of the guide wire and causing injury to the patient's inner cavity, thereby improving the safety of the examination. When the limit assembly 13 is used, the knob 135 is turned, and the knob 135 drives the bidirectional screw 134 to rotate. The bidirectional screw 134 drives the two clamps 131 to move toward each other through the third slider 132, until the inner wall of the arc groove 136 clamps and fixes the guide wire of the digestive endoscope, avoiding accidental pulling of the guide wire and causing injury to the patient's inner cavity.
