6. The tracheal transfer connection structure according to claim 5, characterized in that: The tail ends of the male connection head (151) and the female connection head (152) are respectively provided with trachea connection ends (8).

7. The tracheal transfer connection structure according to claim 6, characterized in that: A third protrusion (10) is provided on one side of the male connection head (151); a disassembly structure (11) is provided on a side of the female connection head (152) away from the second connection plate (3); a first groove (12) is provided on the disassembly structure (11); when the male connection head (151) and the female connection head (152) move in a direction close to each other along the first direction to be combined, the distance between the end of the disassembly structure (11) away from the female connection head (152) and the horizontal plane gradually increases until the third protrusion (10) enters the first groove (12).

8. The tracheal transfer connection structure according to claim 7, characterized in that: The connecting female head (152) comprises a first side surface (16) and a second side surface (17) which are symmetrically arranged, a first slide groove (161) is provided on the upper portion of the first side surface (16), and a first slide rail (171) which matches the first slide groove (161) is provided on the upper portion of the second side surface (17), and the first slide rail (171) is inserted into the first slide groove (161) along the second direction to form a sliding connection; A second clamping portion (18) is provided at the bottom of the first side surface (16), and a third clamping portion (172) is provided at the bottom of the second side surface (17). The third clamping portion (172) is clamped with the second clamping portion (18) along a second direction to limit the length of the first slide rail (171) inserted into the first slide groove (161).

9. The tracheal transfer connection structure according to claim 7, characterized in that: The connecting female head (152) comprises a third side surface (21) and a fourth side surface (22) which are symmetrically arranged. A second slide groove (211) is provided on the third side surface (21). Elastic restraint members (23) are provided on both sides of the second slide groove (211). The elastic restraint member (23) has a first state and a second state. When in the first state, the free ends of the elastic restraint member (23) are away from each other. When in the second state, the free ends of the elastic restraint member (23) are relatively close to each other. One end of the elastic restraint member (23) forms an insertion space with the second slide groove (211). A second slide rail (222) for use with the second slide groove (211) is provided on the fourth side surface (22). The second slide rail (222) is inserted from the insertion space into the second slide groove (211) and switches the elastic restraint member (23) from the second state to the first state.
