[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] See also Figures 1-10 , the present invention provides the following technical solutions:

[0045] Embodiment 1: In order to solve the problem in the prior art that the position of medical equipment is mostly fixed during actual use, and it is inconvenient to adjust the position of the medical equipment up and down and front and back, this embodiment adopts the following technical scheme: a medical multi-directional adjustable clamping arm is provided with a base 1, a support shaft 2, a connecting mechanism 7, a connecting bracket 14, a mounting column 15, a moving mechanism 16 and a fixing slot 27. First, the corresponding medical equipment is fixedly installed on the lower end of the mounting plate 22 by bolts, and the left end of the base 1 is rotatably installed with the support shaft 2. The connecting mechanism 7 includes a fixed connecting rod 8 fixedly connected to the lower end of the support shaft 2, a fixed connecting tube 9 sleeved on the outer surface of the fixed connecting rod 8, a limit block 10 fixedly connected to the front and rear sides of the lower end of the fixed connecting rod 8, and a through hole 11 opened on the fixed connecting rod 8 at equal intervals. An up and down sliding structure is formed between the fixed connecting tube 9 and the limit block 10, and a support limit rod 12 is penetrated at the upper end of the fixed connecting tube 9. The support limit rod 12 is inserted into The left and right ends of the support limit rod 12 are threadedly connected with fixed connecting caps 13 for locking. At the same time, the fixed connecting caps 13 are respectively fitted on the left and right sides of the upper end of the fixed connecting tube 9, and the lower end of the fixed connecting tube 9 is fixedly connected with a connecting bracket 14, and the connecting bracket 14 is respectively fixedly connected to the front and rear sides of the mounting post 15. The upper and lower ends of the left side of the mounting post 15 are evenly spaced with fixed grooves 27. The moving mechanism 16 includes a movable connecting sleeve 17 slidably connected to the outer surface of the mounting post 15, a movable connecting rod 18 inserted in the middle of the movable connecting sleeve 17, a first spring 19 provided between the movable connecting rod 18 and the movable connecting sleeve 17, and a limiting protrusion 20 fixedly connected to the upper and lower ends of the left side of the movable connecting rod 18. The movable connecting rod 18 is telescopically connected to the middle of the movable connecting sleeve 17, and a sliding structure is formed between the movable connecting rod 18 and the mounting post 15. The movable connecting rod 18 drives the limiting protrusion 20 to engage in the fixed groove 27 at the corresponding position. Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, according to actual use needs, by pulling the fixed connecting tube 9, the fixed connecting tube 9 slides with the fixed connecting rod 8, and at the same time, the fixed connecting tube 9 slides with the limit block 10, thereby driving the medical equipment at the lower end to rise and fall, thereby facilitating the adjustment of the use height of the medical equipment, and when the height adjustment is completed, the support limit rod 12 is passed through the upper end of the fixed connecting tube 9, and the support limit rod 12 is inserted into the through hole 11 at the corresponding position to limit the position between the fixed connecting rod 8 and the fixed connecting tube 9, and then the fixed connecting cap 13 threadedly connected to the support limit rod 12 is rotated so that the fixed connecting cap 13 is fitted on the upper end of the fixed connecting tube 9, which is convenient for limiting the support limit rod 12;

[0046] Then, the movable connecting rod 18 can be pressed to the left, and the movable connecting rod 18 slides with the movable connecting sleeve 17. At this time, the movable connecting rod 18 squeezes the first spring 19, so that the first spring 19 is elastically deformed, and the movable connecting rod 18 drives the limiting protrusion 20 to move out of the fixing groove 27, thereby releasing the limit between the movable connecting sleeve 17 and the mounting post 15. Then, the movable connecting sleeve 17 can be pulled forward or backward, and the movable connecting sleeve 17 slides with the mounting post 15, and the movable connecting rod 18 slides with the mounting post 15, thereby facilitating the adjustment of the position of the medical device in the front and rear directions. When the movement is adjusted to the corresponding position, the movable connecting rod 18 is directly released. At this time, the first spring 19 restores its elastic deformation, pushing the movable connecting rod 18 and the movable connecting sleeve 17 to slide, so that the movable connecting rod 18 drives the limiting protrusion 20 to engage in the fixing groove 27 at the corresponding position, thereby facilitating the limitation between the movable connecting sleeve 17 and the mounting post 15.

[0047] Embodiment 2: In the existing medical clamping arms, the use angles of medical equipment are mostly fixed, which is inconvenient to adjust the use angles of the medical equipment according to actual use requirements. Therefore, a support plate 21, a mounting plate 22, a second spring 23, a fixed connecting pin 24, a fixed pull ring 25 and a fixing hole 26 are provided, and a rotating structure is formed between the support plate 21 and the mounting plate 22. The support plate 21 is fixedly connected to the lower end of the movable connecting sleeve 17, and a second spring 23 is provided inside the support plate 21. The movable end of the second spring 23 is fixedly connected to the fixed connecting pin 24, and the upper end of the fixed connecting pin 24 is fixedly connected to the fixed pull ring 25. A sliding structure is formed between the fixed pull ring 25 and the support plate 21, and the fixed connecting pin 24 is telescopically connected to the front and rear ends of the support plate 21 respectively, and the fixed connecting pin 24 is inserted into the fixing hole 26 at the corresponding position. The fixing hole 26 is opened at an equal angle at the upper end of the mounting plate 22, such as Figure 3 、 Figure 9 and Figure 10The second spring 23 recovers its elastic deformation and pushes the fixing connecting pin 24 to slide between the support plate 21, so that the fixing connecting pin 24 is inserted into the fixing hole 26 at the corresponding position, thereby facilitating the limiting of the support plate 21 and the mounting plate 22.

[0048] Example 3: The existing medical clamping arm is not convenient for flipping and adjusting the medical equipment as a whole during use, and is not convenient for multi-directional adjustment according to the usage scenario. Therefore, a support shaft 2, a connecting column 3, an electric telescopic rod 4, a fixed connecting block 5 and a fixed mounting block 6 are provided. The connecting column 3 is fixedly connected to the middle part of the upper end of the support shaft 2, and the connecting column 3 drives the support shaft 2 to rotate at the left end of the base 1. The electric telescopic rod 4 is fixedly installed on the upper left end of the base 1, and the output end of the electric telescopic rod 4 is fixedly connected to the fixed connecting block 5. The fixed connecting block 5 is rotatably connected to the fixed mounting block 6, and a sliding structure is formed between the fixed mounting block 6 and the connecting column 3, as shown in FIG. Figure 1 、 Figure 2 and Figure 3 As shown, during use, by starting the electric telescopic rod 4 installed at the upper end of the base 1, the electric telescopic rod 4 pushes the fixed connecting block 5 to move, so that the fixed connecting block 5 and the fixed mounting block 6 rotate. At this time, the fixed mounting block 6 slides with the connecting column 3, so that the connecting column 3 drives the support shaft 2 to rotate at the left end of the base 1, and then drives the use angle of the medical device at the lower end to flip and adjust. In summary, through the above operations, the use position and use angle of the medical device can be adjusted in multiple directions very conveniently, thereby achieving a better use state.
