[0046] Please refer to the attached document. Figures 2-6In this embodiment, the connecting groove 10a includes a first sub-connecting groove 10b and a second sub-connecting groove 10c. The first sub-connecting groove 10b is arranged in an inclined direction, and the second sub-connecting groove 10c is arranged in a horizontal direction. The second sub-connecting groove 10c is located below the first sub-connecting groove 10b and communicates with the first sub-connecting groove 10b. The connecting post 21 passes through the first sub-connecting groove 10b and the second sub-connecting groove 10c in sequence as the first handle 10 and the second handle 20 rotate, and stops in the second sub-connecting groove 10c. This allows the connecting post 21 to be inserted into the second sub-connecting groove 10c during rotation, thereby facilitating the inner wall of the second sub-connecting groove 10c to restrict the position of the connecting post 21. This allows the second handle 20 and the first handle 10 to be in an assembled state. By rotating, the second handle 20 and the first handle 10 are in an assembled state, avoiding the second handle 20 being assembled with the first handle 10 by means of screw connection, thus improving the assembly convenience of the handle device 100.
[0047] Please refer to the attached document. Figures 2-6 In this embodiment, the first sub-connecting groove 10b is arranged along an inclined direction; the connecting post 21 protrudes from the inner wall of the rotating groove 20a and is an integral structure with the second handle 20, which strengthens the connection strength between the connecting post 21 and the second handle 20, ensures the connection stability between the connecting post 21 and the second handle 20, and prevents the connecting post 21 from separating from the second handle 20. The first sub-connecting groove 10b is arranged in an inclined direction to enable the connecting post 21 to connect with the connecting groove 10a during rotation.
[0048] Please refer to the attached document. Figures 2-4 In this embodiment, the second sub-connecting groove 10c is arranged horizontally; the second handle 20 is also provided with an elastic element 22, which is arranged along the length of the second handle 20. The elastic element 22 is exposed to the rotating groove 20a and applies an elastic force to the rotating column 11. When the connecting column 21 is in the second sub-connecting groove 10c, the first handle 10 and the second handle 20 compress the elastic element 22, and the elastic element 22 applies a downward elastic force to the first handle 10, so that the connecting column 21 contacts the inner wall of the second sub-connecting groove 10c under the downward elastic force, so that the connecting column 21 presses against the inner wall of the connecting groove 10a. The second handle 20 and the first handle 10 are in an assembled state, avoiding the second handle 20 from being assembled with the first handle 10 by means of screw connection, thus improving the assembly convenience of the handle device 100.
[0049] Optionally, the elastic element 22 includes an elastic pad 221, which is arranged flat and can be arranged flat along the horizontal direction. During the process of installing the first handle 10 on the second handle 20, the end face of the first handle 10 contacts the elastic pad 221 and is arranged flat under the action of the elastic pad 221, so that the second handle 20 can be installed flat on the first handle 10.
[0050] Furthermore, the elastic element 22 also includes an elastic ring 222, which is arranged in a curved manner along the horizontal direction and applies a downward elastic force to the first handle 10, so that the connecting post 21 contacts the inner wall of the second sub-connecting groove 10c under the downward elastic force, so that the connecting post 21 presses against the inner wall of the connecting groove 10a, and the second handle 20 and the first handle 10 are in an assembled state.
[0051] The second sub-connecting groove 10c is connected to the engaging groove 10d, and the connecting post 21 engages in the engaging groove 10d so that the elastic force applied by the elastic element 22 can engage the connecting post 21 in the engaging groove 10d. This allows the inner contour of the engaging groove 10d to restrict the position of the connecting post, increases the resistance of the connecting post, and enhances the connection stability between the connecting post 21 and the second sub-connecting groove 10c.
[0052] Please refer to the attached document. Figures 2-6 In this embodiment, there are multiple connecting grooves 10a, which are arranged at intervals along the circumferential direction and distributed at different positions of the first handle 10; there are multiple rotating columns 11, which are arranged corresponding to the multiple connecting grooves 10a. By arranging multiple connecting grooves 10a and multiple rotating columns 11, the connection strength between the first handle 10 and the second handle 20 is increased, the assembly stability between the first handle 10 and the second handle 20 is improved, and the separation between the first handle 10 and the second handle 20 is avoided.

The second handle 20 and the first handle 10 are sealed together, which ensures the sealing effect between the second handle 20 and the first handle 10 and prevents water from entering at the connection between the second handle 20 and the first handle 10.
[0054] Please refer to the attached document. Figure 3 and 6 In this embodiment of the application, the first handle 10 is fitted with a sealing ring 12, which is located on the lower side of the connecting groove 10a and seals the second handle 20 and the first handle 10. The sealing ring 12 achieves a sealed connection between the second handle 20 and the first handle 10, ensuring the sealing effect between the second handle 20 and the first handle 10 and preventing water from entering at the connection between the second handle 20 and the first handle 10.
[0055] In a second embodiment, an endoscopic device includes a handle 100, which, as part of the endoscopic device, allows for easy visual inspection of living information that cannot be obtained from ordinary observation images. For example, the endoscopic device can highlight lesions and fine structures of blood vessels formed in the mucosal or submucosal layer.
[0056] At this time, the handle device 100 includes a first handle 10 and a second handle 20. The first handle 10 is provided with a connecting groove 10a, which is arranged along an inclined direction. The second handle 20 is disposed on one side of the first handle 10.
