[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a snake bone device for endoscope, comprising a joint 1, a first protrusion 2 is connected to the top surface of the joint 1, a movable groove 3 is provided on the inner surface of the first protrusion 2, a spring 4 is connected to the inner surface of the movable groove 3, a movable block 5 is connected to one end surface of the spring 4, a spherical protrusion 6 is connected to one side surface of the movable block 5, a second protrusion 7 is connected to the bottom surface of the joint 1, a rotation groove 8 is provided on the outer surface of the second protrusion 7, a first end tube 9 is connected to the bottom end of one joint 1, and a second end tube 10 is connected to the top end of the other joint 1.

[0022] Preferably: the movable block 5 forms a sliding connection with the first protrusion 2 through the movable groove 3, the movable block 5 forms an elastic structure with the first protrusion 2 through the movable groove 3 and the spring 4, the spherical protrusion 6 forms a sliding connection with the first protrusion 2 through the movable groove 3, and the position and size of the spherical protrusion 6 match the position and size of the rotating groove 8.

[0023] During specific use, the movable block 5 can slide in the movable groove 3. When the spherical protrusion 6 is subjected to extrusion force, the spherical protrusion 6 will slide into the movable groove 3, thereby driving the movable block 5 to squeeze the spring 4 in the movable groove 3. When the extrusion force on the spherical protrusion 6 disappears, the spring 4 will push the movable block 5 to move in the movable groove 3 through elasticity, thereby causing the spherical protrusion 6 to slide out of the movable groove 3, allowing one end of the spherical protrusion 6 to enter the rotating groove 8.

[0024] Preferably, the top surface of the first end tube 9 is connected with the first protrusion 2 , and the bottom surface of the second end tube 10 is connected with the second protrusion 7 .

[0025] During specific use, the first end tube 9 can be connected to the second protrusion 7 at the lower end of the condyle 1 through the first protrusion 2, and the second protrusion 7 at the bottom of the second end tube 10 can be connected to the first protrusion 2 at the upper end of the condyle 1.

[0026] Working principle: when using the snake bone device for endoscope, slide the second protrusion 7 at the bottom of a joint 1 close to the inner side of the first protrusion 2 at the top of the first end tube 9. When the second protrusion 7 contacts the spherical protrusion 6 protruding from one side of the first protrusion 2, the spherical protrusion 6 will be pushed to move into the movable groove 3 through the squeezing force, so that the movable block 5 connected to one side of the spherical protrusion 6 will move in the movable groove 3 and squeeze the spring 4 at the same time. When the rotating groove 8 on the second protrusion 7 moves to the position of the spherical protrusion 6, the spherical protrusion 6 is no longer squeezed. At this time, the spring 4 will push the movable block 5 through elasticity, so that the spherical protrusion 6 will move from the movable groove 3 to the rotating groove 8, so that the spherical protrusion 6 will be engaged in the rotating groove 8. In this way, the first protrusion 2 and the second protrusion 7 will be connected together, thereby completing the installation of a joint 1. In this way, multiple joints 1 and second end tubes 10 can be installed. After the assembly of the entire snake bone is completed, when the spherical protrusion 6 extends into the rotating groove 8, the second protrusion 7 can be rotated along the spherical protrusion 6, so that the entire snake bone can be rotated. When one of the joints 1 is damaged and needs to be replaced, it is only necessary to pull the damaged joint 1 to separate the spherical protrusion 6 in the first protrusion 2 at the upper end of the joint 1 from the rotating groove 8 in the second protrusion 7 at the lower end of another joint 1, so that the upper end of the damaged joint 1 can be separated from the other joints 1. At this time, pull the damaged joint 1 again to separate the rotating groove 8 on the second protrusion 7 at the bottom of the joint 1 from the spherical protrusion 6 in the first protrusion 2 on another joint 1, so that the damaged joint 1 can be separated from the other joints 1 at the lower end. In this way, the damaged joint 1 can be completely disassembled, allowing the operator to replace it with a new joint 1 for use, thereby avoiding the need to purchase the entire snake bone and reducing maintenance costs.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
