Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific situation. In addition, the terms "first", "second", "third", and the like are used to distinguish the description, and should not be understood as indicating or implying relative importance.

[0020] Example 1 In a first embodiment of the present invention, an endoscope butt joint structure is provided, A storage case 21 in which a storage space is provided; a transmission body (22) disposed in the receiving space and capable of sliding within the receiving space; The power transmission body 22 is provided at both ends thereof, and the pulling line attachment bodies 23 and 24 are provided in the receiving space. and drawstrings 31, 32, one end of which is fixedly connected to the drawstring attachment bodies 23, 24.

[0021] In the above-mentioned solution, as shown in Fig. 1 to Fig. 4, the housing case 21 is U-shaped, the housing case 21 has a hollow structure, and a housing space is formed by the hollow structure, the power transmission body 22 is mounted in the housing space, and the power transmission body 22 can slide along the inner wall of the housing space in the housing space and can roll along the inner wall of the housing space. A first drawing thread attachment body 23 and a second drawing thread 24 are respectively installed on both ends of the power transmission body 22, and one side of the first drawing thread attachment body 23 and the second drawing thread attachment body 24 contacts the surface of the power transmission body 22 at the corresponding end close to both ends of the housing case 21, and the two are neither fixedly connected nor detachably connected, and the contact manner may be other manners such as point contact, line contact, surface contact, etc., and is not limited here. The first drawing thread 31 is fixedly connected to the first drawing thread attachment body 23, and the second drawing thread 32 is fixedly connected to the second drawing thread attachment body 24, and the fixing method may be adhesion, integral molding, etc., and is not limited here.

[0022] The shape of the storage case 21 may further be V-shaped, W-shaped, etc., as long as the storage case 21 is attached within a member that engages with it, and the present application does not limit the shape of the storage case 21.

[0023] The draw line attachment bodies 23, 24 include a first draw line attachment body 23 and a second draw line attachment body 24.

[0024] The drag threads 31 , 32 include a first drag thread 31 and a second drag thread 32 .

[0025] In addition, the present application may provide four pulling strings, i.e., two endoscopic butt connection structures, to realize the movement of the pulling strings in other directions, and the structures of the two endoscopic butt connection structures may be the same or different, and the two connection structures are installed to form an included angle. The connection structure of the present application may change the connection relationship, such as the number and position, as necessary to realize the movement of multiple pulling strings.

[0026] Therefore, the endoscope butt connection structure according to the present invention can make the transmission body 22 move in one direction along the inner wall of the casing 21 by pushing the first drawstring attachment body 23 or the second drawstring attachment body 24 with an external force, and can further move the corresponding drawstring. The movable range of the transmission body 22 in the present application is determined by the shape and size of the accommodating space, that is, the transmission body 22 can slide according to the path and space previously set up to accommodate the casing 21, and does not affect the arrangement of other members during the sliding process. This may be understood as the transmission body 22 not affecting the movement or arrangement of other members located on the outer wall of the casing 21 due to its own movement during the moving process, reducing the moving space of the transmission body 22 and reducing the corresponding structure of the endoscope housing engaged with the transmission body 22.

[0027] Furthermore, thread passages 211, 212 are provided on both sides of the storage case 21, and the drawing threads 31, 32 are connected to the drawing thread attachment bodies 23, 24 through the thread passages 211, 212.

[0028] In the above-mentioned solution, as shown in Fig. 3, a first threading passage 211 and a second threading passage 212 are provided on both sides of the storage case 21, and the first threading passage 211 and the second threading passage 212 may be provided symmetrically or asymmetrically along the symmetric axis of the storage case 21. In the present application, it is preferred that the first threading passage 211 and the second threading passage 212 are provided symmetrically, and the sizes of the first threading passage 211 and the second threading passage 212 may be set based on the thicknesses of the first drawing yarn 31 and the second drawing yarn, or may be set based on the material of the transmission body 22 in the storage case 21. If the transmission body 22 is solid, the first threading passage 211 and the second threading passage 212 may be provided wide, which ensures that the transmission body 22 falls from the storage case 21 and also reduces the weight of the storage case 21. When the transmission body 22 is a viscous liquid, the first threading passage 211 and the second threading passage 212 may be narrowed, and only the corresponding pulling thread is allowed to pass through. In the field of endoscopy, the diameter of the pulling thread is very small, that is, the first threading passage 211 and the second threading passage 212 are correspondingly very narrow. In this way, when the pushing assembly pushes the transmission body 22, the transmission body 22 will not be pushed out of the first threading passage 211 and the second threading passage 212.

[0029] In addition, in the present application, the threading passage is preferably in the form of a strip. In addition, the shape of the threading passage may be circular, square, triangular, etc., and is not limited thereto.

[0030] In the present application, a threading passage is provided in the receiving case 21, so that the drawing thread can move along the threading passage during the movement of the transmission body 22, thereby ensuring that one end of the drawing thread is located outside the receiving case 21, and preventing the drawing thread from entering the receiving case 21 and affecting the movement of the transmission body 22.

The transmission body 22 may also be silica gel, etc.

[0034] Furthermore, both ends of the transmission body 22 are not higher than both ends of the accommodating case 21 .

[0035] In the above-mentioned solution, the transmission body 22 can slide in the housing case 21 by the pushing of the drawing line attachment bodies 23, 24, but the transmission body 22 cannot slide out from both ends of the housing case 21, and the transmission body 22 must always be held in the housing case 21, that is, both ends of the transmission body 22 must not exceed (be higher than) both ends of the housing case 21 within the maximum distance that the housing case can slide. If either one of the ends of the transmission body 22 slides out of the housing case 21, the entire connection structure will be damaged and cannot be used multiple times.

[0036] Furthermore, a lock groove is provided on the inner wall of the receiving case 21 .

[0037] In the above-mentioned solution, as shown in Fig. 4, locking grooves 26 are provided in positions close to both ends of the inner wall of the storage case 21, and the locking grooves 26 may be provided at either end or at only one end of the storage case 21. By providing the locking grooves 26 on the inner wall of the storage case 21, a member connected to the storage case 21 can be engaged with the locking grooves 26, thereby realizing the locking of the member in the storage case 21 and preventing the member from moving beyond a predetermined position inside the storage case.

[0038] Furthermore, limiting portions are provided on both ends of the container case 21 .

[0039] In the above solution, limiting portions are provided on the end faces or inner walls at both ends of the accommodating case 21, and the limiting portions may be provided as protrusions. By making the maximum dimension of the limiting portion smaller than the maximum dimension of the transmission body 22, the transmission body 22 is prevented from coming out of the accommodating case 21 when moving within the accommodating case 21, and the transmission body 22 is restricted within the accommodating case 21.

[0040] In addition, the restricting portions at both ends of the accommodating case 21 may be set as reduced portions, and the cross-sectional dimensions of the reduced portions are made smaller than the maximum dimension of the transmission body 22 to restrict the transmission body 22 within the accommodating case 21.
