[0032] The small-diameter rotary joint is fixedly connected to the end of the robotic arm via a corresponding clamp, so that the small-diameter rotary joint can be assembled and disassembled between the robotic arm and the clamp.

[0033] The outer side of one end of the clamp is provided with an external thread 12. The clamp is connected to the corresponding large-mouth rotary joint and small-mouth rotary joint through the external thread 12. The external thread 12 allows the clamp to be individually disassembled and assembled with the corresponding large-mouth rotary joint and small-mouth rotary joint.

[0034] In this embodiment, both the inner and outer surfaces of the flexible sheath 1 are provided with wear-resistant layers to improve the wear resistance of the flexible sheath 1.

[0035] Specifically, the wear-resistant layer uses nylon fabric, Oxford cloth, etc.

[0036] In this embodiment, the large-diameter rotary joint includes a large-diameter support ring 2 and a large-diameter internal threaded sleeve 4. One end of the large-diameter support ring 2 is fixedly connected to one end of the flexible sheath 1, and the other end of the large-diameter support ring 2 is rotatably connected to one end of the large-diameter internal threaded sleeve 4 so that when the mechanical arm rotates through the rotary seat after being installed on the robotic arm, it will not affect the robotic arm. The large-diameter internal threaded sleeve 4 is connected to the external thread 12 on the corresponding clamp.

[0037] Specifically, the large-diameter support ring 2 and the large-diameter internal threaded sleeve 4 are connected by a bearing rotation. The inner ring of the bearing is fixed outside the large-diameter internal threaded sleeve 4 and fixedly installed inside the large-diameter support ring 2.

[0038] In this embodiment, the small-mouth rotary joint includes a small-mouth support ring 3 and a small-mouth internal threaded sleeve 5. One end of the small-mouth support ring 3 is fixedly connected to the other end of the flexible sheath 1, and the other end of the small-mouth support ring 3 is rotatably connected to one end of the small-mouth internal threaded sleeve 5 so that when it is installed on the robotic arm, it will not affect the robotic arm when it rotates at the end of the robotic arm. The small-mouth internal threaded sleeve 5 is connected to the external thread 12 on the corresponding clamp.

[0039] Specifically, the small-diameter support ring 3 and the small-diameter internal threaded sleeve 5 are connected by a bearing rotation. The inner ring of the bearing is sleeved and fixed outside the small-diameter internal threaded sleeve 5, and the inner ring of the bearing is fixedly installed inside the small-diameter support ring 3.

[0040] In this embodiment, the clamp includes a first clamp plate 6 and a second clamp plate 7; the first clamp plate 6 has countersunk holes 9 at both ends, with the larger end of the countersunk hole 9 located on the outer side of the first clamp plate 6 and the smaller end of the countersunk hole 9 located on the end face of the first clamp plate 6; the second clamp plate 7 has threaded holes 10 at both ends corresponding to the countersunk holes 9; bolts 11 are fixedly installed between the threaded holes 10 and the corresponding countersunk holes 9, so that the first clamp plate 6 and the second clamp plate 7 form a ring shape, so that the first clamp plate 6 and the second clamp plate 7 can be disassembled and assembled with the robotic arm;

[0041] External thread 12 is provided on the outer side of one end of hoop 6 and hoop 7; hoop 6 and hoop 7 are connected to the corresponding large-diameter internal thread sleeve 4 and small-diameter internal thread sleeve 5 through external thread 12 so that they can be disassembled and assembled.

[0042] In this embodiment, rubber pads 8 corresponding to the shape of the inner sides of hoop 6 and hoop 7 are fixedly installed, so that when hoop 6 and hoop 7 are installed on the robotic arm, the robotic arm is protected by the rubber pads 8.

[0043] Specifically, let's take a robotic arm with a circular rotating base as an example:

[0044] In use, the flexible sleeve 1 is put from the end of the robotic arm to the beginning of the robotic arm through the large-mouth rotary joint until the end of the robotic arm protrudes from the small-mouth rotary joint of the flexible sleeve 1. Then, the corresponding hoop plate 1 6 and hoop plate 2 7 are fixedly installed on the circumferential surface of the output end of the robotic arm's rotating seat and the circumferential surface of the end of the robotic arm, respectively. Finally, the large-mouth internal thread sleeve 4 and the small-mouth internal thread sleeve 5 are connected to the external threads 12 of the corresponding plate 1 6 and hoop plate 2 7.
