[0028] A rotating shaft 31 is provided on the side of the placement plate 3, and the placement plate 3 can rotate around the rotating shaft 31 as the axis. An adapter 4 is sleeved on the outer side of the rotating shaft 31, and the adapter 4 is fixedly connected to the lifting rod 2. The adapter 4 includes an annular plate 41, and the side of the placement plate 3 abuts against the side of the annular plate 41. The lifting rod 2 includes a fixing hole 23. A shaft sleeve 42 is provided on the side of the annular plate 41 away from the placement plate 3. The shaft sleeve 42 is inserted into the fixing hole 23 for fixing. A mounting hole 43 is provided inside the shaft sleeve 42, and the rotating shaft 31 is inserted into the mounting hole 43. A knob 5 is connected to the end of the rotating shaft 31, and the knob 5 is located on the side of the shaft sleeve 42;

[0029] like Figure 6 As shown, when the placement plate 3 does not need to be rotated, the placement plate 3 can be clamped by tightening the knob 5 to fix the angle of the placement plate 3. When the placement plate 3 needs to be rotated, the knob 5 can be loosened. At this time, the placement plate 3 can be rotated along the rotating shaft 31 to adjust the angle of the placement plate 3, which is convenient for medical staff to operate.

[0030] Two clamping blocks 22 are provided at the upper end of the lifting rod 2, and the fixing hole 23 is located between the two clamping blocks 22. The upper ends of the two clamping blocks 22 are connected by bolts. By tightening the bolts, the upper ends of the two clamping blocks 22 can be close to each other, so that the fixing hole 23 is deformed, thereby clamping the sleeve 42. Flat surfaces 46 are provided on both sides of the sleeve 42, and the inner wall of the fixing hole 23 is close to the outer wall of the sleeve 42. In this embodiment, the two clamping blocks 22 are connected by bolts, so that the adapter 4 can be clamped to effectively prevent the adapter 4 from rotating. In addition, the adapter 4 is provided with a flat surface 46, which can effectively prevent the adapter 4 from rotating relative to the lifting rod 2, thereby greatly improving the fixing effect of the adapter 4.

[0031] The outer side of the sleeve 42 abuts against a gasket 6, the screw of the knob 5 passes through the gasket 6 and is inserted into the shaft 31 for fixation, and the inner side of the knob 5 abuts against the outer side of the gasket 6.

[0032] The annular plate 41 is provided with a plurality of convex ribs 45 distributed along the axis of the rotating shaft 31 on one side facing the placement plate 3, and the side surface of the placement plate 3 abuts against the side surface of the convex rib 45. By providing a plurality of convex ribs 45, the friction between the annular plate 41 and the side surface of the placement plate 3 can be effectively increased, thereby improving the fixing effect of the placement plate 3.

[0033] The back of the placement plate 3 is provided with a movable push rod 9, and a handle 8 is fixed on the side of the placement plate 3 away from the rotating shaft 31. The annular plate 41 includes a plurality of limiting holes 44 distributed along its axis. One end of the push rod 9 can be inserted into or out of the limiting hole 44 and the other end is inserted into the handle 8. The placement plate 3 is rotated so that the push rod 9 can be inserted into the limiting holes 44 at different positions. Specifically, a plurality of guide blocks 32 are provided on the back of the placement plate 3, and the push rod 9 passes through the guide blocks 32. The outer sides of the push rod 9 are respectively An annular rib 92 and a limiting rib 93 are provided, and the limiting rib 93 can abut against or stay away from the side of the annular plate 41. A spring 100 is sleeved on the outer side of the push rod 9, and one end of the spring 100 abuts against the side of the annular rib 92 facing the handle 8 and the other end abuts against the side of the guide block 32 facing the rotating shaft 31. A guide groove 81 is provided on the inner side of the handle 8. A slider 91 is connected to one end of the push rod 9, and the slider 91 exposes the guide groove 81 toward the side of the push rod 9, and the slider 91 is inserted into the guide groove 81 toward the side of the guide groove 81.

[0034] By cooperating with the push rod 9 and the limiting hole 44, the position of the placement plate 3 can be fixed after the knob 5 is loosened. When the position of the placement plate 3 is fixed, one end of the push rod 9 is inserted into the limiting hole 44 for limiting, and the placement plate 3 cannot be rotated at this time; when it is necessary to adjust the angle of the placement plate 3, the medical staff holds the handle 8 with one hand, and the palm of the hand can press the slider 91, and the slider 91 can move along the guide groove 81 and synchronously drive the push rod 9 to move. During the movement of the push rod 9, the spring 100 is compressed, and the end of the push rod 9 is separated from the limiting hole 44, and the placement plate 3 can be rotated at this time. When the angle of the placement plate 3 is adjusted, the medical staff When the hand leaves the handle 8, the push rod 9 receives the resilience of the spring 100 and moves toward the annular plate 41. If the end of the push rod 9 is not facing the corresponding limiting hole 44, the end of the push rod 9 abuts against the side of the annular plate 41. At this time, by slightly rotating the placement plate 3, when the push rod 9 faces the limiting hole 44, the push rod 9 can be quickly inserted into the limiting hole 44 to fix the position of the placement plate 3. The above-mentioned structural combination can not only further improve the position fixing effect of the placement plate 3, making the structure more reliable, but also realize one-handed operation of medical staff, which greatly facilitates the angle adjustment of the placement plate 3 and is easy to use.
