Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Referring to Figures 1-4 The utility model provides a technical scheme: a trachea intubation structure of mouse, include: pipe joint 1, iron sheet 11 and support set, pipe joint 1 one end is fixed with intubation 2,

[0024] Support set includes collar 4, first screw rod 5 is connected in the screw thread in the top of collar 4, is fixed in the one end of first screw rod 5 and is screwed disc 6, and is provided in the auxiliary arm 7 of one side of collar 4, auxiliary arm 7 one end is connected in the screw thread with second screw rod 8, and second screw rod 8 one end is fixed with seat disc 9, and seat disc 9 bottom is fixed with magnetic block 10;

[0025] Pipe joint 1 and intubation 2 are fixed together, and iron sheet 11 needs to be fixed on experimental platform in advance to cooperate with support set, and the threaded end of first screw rod 5 can penetrate through collar 4 to operate intubation 2, and the auxiliary arm 7 of collar 4 is provided with threaded groove for the rotation control of second screw rod 8, and the magnetic block 10 of seat disc 9 at one end of second screw rod 8 can be attracted to the outer wall of iron sheet 11 after the rotation control of second screw rod 8, to assist in supporting operation.

[0026] Further preferably, the outer wall of iron sheet 11 is provided with two through holes symmetrical to each other;

[0027] The through hole of iron sheet 11 is used for inserting screw, so that the threaded end of screw is inserted into the experimental platform, and the driving end is locked to iron sheet 11, to assist the magnetic attraction connection of magnetic block 10 of seat disc 9.
