The arthroscope body 2 is inserted from the top of the lower connecting sleeve 11 so that the arthroscope body 2 is located inside the outer protection tube 18. The limiting protrusion 19 inside the lower connecting sleeve 11 is located outside the arthroscope body 2 to limit it. At the same time, the opening size at the inner bottom of the lower connecting sleeve 11 is smaller than the upper end size of the lower connecting sleeve 11, and the arthroscope body 2 is clamped inside the outer protection tube 18. Subsequently, the upper connecting sleeve 12 is inserted from above the lower connecting sleeve 11, and the inner clamping edge 13 is correspondingly clamped into the stepped clamping groove 14 at the top of the lower connecting sleeve 11, so that the side protection cylinders 15 on the sides of the lower connecting sleeve 11 and the upper connecting sleeve 12 are correspondingly clamped together, covering the joint tube on the side of the arthroscope body 2. Then, the fixing sleeve 17 is fixed by screwing it along the external thread one 16 outside the side protection cylinder 15. Since the inner clamping edge 13 is clamped in the stepped clamping groove 14 to protect the arthroscope body 2, when in use, the upper connecting sleeve 12 can be removed by removing the fixing sleeve 17, and then the arthroscope body 2 can be withdrawn.
