[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0027] Embodiment 1:

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0029] The adjustable handwheel limit structure of the video tracheal intubation scope includes a handwheel shaft sleeve 5, a drum turntable 4 and a handwheel connecting rod 3. The handwheel shaft sleeve 5 is sleeved with the drum turntable 4, and at the same time, a rod body passing through the center of the drum turntable 4 is arranged on the handwheel shaft sleeve 5, and the handwheel shaft sleeve 5 and the drum turntable 4 are assembled together for convenient use. In order to carry out limit adjustment, a detachable limit rod 2 is arranged on the rod body, so that the limit rod 2 can be disassembled or assembled, which is convenient for use and conducive to maintenance. In order to limit the rotation angle of the structure, a limit block 6 is movably arranged on the surface of the handwheel shaft sleeve 5, so that it can limit the rotation of the limit rod 2. In order to facilitate adjustment and operation, the handwheel connecting rod 3 is clamped with one end of the rod body, which is convenient for driving the rotation of this structure through the handwheel connecting rod 3 for use.

[0030] As Figure 1 , 2 shown:

[0031] In order to realize the detachable assembly of the limit rod 2, a limit rod hole 8 is opened on the rod body, and at the same time, internal threads are opened on the limit rod hole 8. In order to cooperate with the internal threads, external threads are opened on the limit rod 2, so that the limit rod 2 is installed on the rod body by means of threaded connection.

[0032] As Figure 1 , 3 shown:

[0033] A limit rod sliding groove 11 is opened on the handwheel shaft sleeve 5, so that the limit rod 2 passes through the limit rod sliding groove 11 and is exposed. This method is convenient for the rotation of the limit rod 2 and is not affected by the handwheel shaft sleeve 5 during rotation, which is convenient for angle adjustment.

[0034] As Figure 1 , 5 shown:

[0035] The limit block 6 is fixed to the handwheel shaft sleeve 5 through a positioning screw 7. In order to realize the installation of the limit block 6, a screw groove 13 matching the positioning screw 7 is opened on the handwheel shaft sleeve 5;

[0036] In order to realize the adjustment of the limit block 6 and thus adjust the rotation angle of the limit rod 2, an adjustment groove 12 is opened on the limit block 6, so that the positioning screw 7 passes through the limit block 6. When the limit block 6 needs to be adjusted, it can be moved by loosening or tightening the positioning screw 7, so as to realize the rotation limit angle of the limit rod 2.

[0037] As Figure 1 , 4 shown:

[0038] A clamping square block 9 is provided at one end of the rod body, and a clamping square hole 10 cooperating with the clamping square block 9 is provided on the handwheel connecting rod 3, so as to connect the handwheel connecting rod 3 with the rod body, facilitating the use of the handwheel connecting rod 3 to drive the rod body to rotate, causing the limit rod 2 to rotate. A handwheel connecting rod sleeve 1 is provided at one end of the handwheel connecting rod 4, which is used as a handle for convenient use.

[0039] Working principle:

[0040] Push the handwheel connecting rod sleeve 1 to drive the drum turntable 4 to perform a rotational motion. The movement of the drum turntable 4 drives the limit rod 2 to perform a rotational motion. When the limit rod 2 performs a rotational motion, it will be limited by the limit block 6. The movement of the limit block 6 is realized by loosening and tightening the positioning screw 7, and the rotation limit angle of the limit rod 2 is realized through the limit block 6.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
