[0020] See also Figures 1 to 6 , the utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, a gastroscope guided ventilation device comprises: an arc-shaped sheet 1 and a circular ring frame 2, wherein the circular ring frame 2 is arranged at the vertical surface of the arc-shaped sheet 1, and a notch is opened at the vertical surface of the arc-shaped sheet 1, a vertical guide tube 3 is arranged in the notch of the arc-shaped sheet 1, and a ventilation groove is opened on the vertical guide tube 3, rectangular blocks 4 are arranged at the vertical surfaces on both sides of the vertical guide tube 3, and cylindrical holes are opened through the upper surface of the rectangular block 4, the vertical guide tube 3 is connected to the arc-shaped guide tube 5 away from the vertical surface of the arc-shaped sheet 1, a movable groove 6 is opened at the intersection of the rectangular block 4 and the arc-shaped sheet 1, and a docking groove is opened at the bottom surface inside the movable groove 6.
[0021] like Figure 2 As shown, a convex rod 7 is arranged inside the movable groove 6, and the convex rod 7 is connected to the guide block 8.
[0022] like Figure 4 and Figure 5 As shown, a rectangular groove 9 is provided on the arc guide tube 5, and the width of the rectangular groove 9 corresponds to the diameter of the guide rod 20, a pair of rectangular rods 10 are provided at the vertical plane of the vertical guide tube 3 away from the arc sheet 1, a pair of mounting grooves 11 are provided at the vertical plane of the arc guide tube 5 close to the arc sheet 1, and the size of the cross-section of the mounting groove 11 is the same as the area of the cross-section of the rectangular rod 10, a lifting groove 12 is provided on the bottom surface inside the mounting groove 11, a memory spring 111 is provided on the bottom surface inside the lifting groove 12, the upper end of the memory spring 111 is connected to the moving plate 13, and the moving block 13 and the lifting groove 12 are in a sliding connection relationship, and a limiting block 14 is provided on the upper surface of the moving plate 13.
[0023] like Figure 4 and Figure 6 As shown, a mounting block 15 is provided at the vertical surface of the rectangular rod 10 away from the vertical guide tube 3, and a one-way arc block 16 is penetrated through the rod body of the mounting block 15. The one-way arc block 16 is provided with a circle of annular notches 17 near the vertical surface of the rectangular rod 10.
[0024] like Figure 4 and Figure 6As shown, a slide groove 18 is provided on the upper surface of the mounting block 15, a slider is provided inside the slide groove 18, and an arc ring 19 is connected to the upper surface of the slider, a guide rod 20 is provided on the vertical surface of the arc ring 19 facing outward, and the guide rod 20 is fixed to the arc ring 19.
[0025] like Figure 6 As shown, an arc frame 21 is installed at the vertical surface of the arc ring 19 close to the vertical guide tube 3.
[0026] Working principle: when replacing the arc guide tube 5, first align the rectangular rod 10 with the installation slot 11.
