[0048] Specifically, the flexible support rod 6 can be made of medical transparent rubber, which bends and deforms when subjected to force. The flexible support rod 6 can be made of a material with the same strength as the side straw 3.

[0049] Based on the above embodiment, the flexible support rod 6 is a through-pipe structure so as to place the cable of the camera 5 .

[0050] Example 3

[0051] like Figure 1 and Figure 3 On the basis of Examples 1 and 2, the hand-held part 1 is slidably connected to a limit rod 61, one end of the limit rod 61 abuts against the side of the flexible support rod 6, and the other end extends out of the hand-held part 1, and the limit rod 61 is provided with a spring 62, and the two ends of the spring 62 are respectively fixedly connected to the hand-held part 1 and the limit rod 61.

[0052] The beneficial effect of adopting the preferred solution in the above embodiment is that after sliding the flexible support rod 6, the elastic force of the spring 62 can make the limit rod 61 press against the side of the flexible support rod 6 to prevent the flexible support rod 6 from continuing to slide.

[0053] As a specific solution of the above embodiment, a fixing plate 611 is fixedly connected to the middle portion of the limiting rod 61 to achieve a fixed connection with the spring 62 .

[0054] Example 4

[0055] like Figure 1 and Figure 2 On the basis of embodiments 1-3, two side straws 3 are arranged on opposite sides of the middle straw 2.

[0056] The beneficial effect of adopting the preferred solution in the above embodiment is that when the pull rope 4 is pulled to cause the middle straw 2 to bend under force, the flexible support rod 6 can directly form a supporting effect relative to the deformation direction of the middle straw 2, preventing the middle straw 2 from twisting, causing the opening direction of the suction hole 22 to change.

[0057] As a parallel solution of the above embodiment, the two side straws 3 form an obtuse angle with respect to the line connecting the axes of the middle straw 2 .

[0058] Example 5
