[0025] Preferably: the shielding mechanism includes: a second surface thread 11, a second thread groove 12, a screw cap 13, a second card groove 14 and a protrusion 15, the other end of the protective cover 8 extends into the second thread groove 12, the inner surface of the second thread groove 12 is connected to the second surface thread 11 opened on the outer surface of the protective cover 8, and the second thread groove 12 is opened on one end surface of the screw cap 13, a second card groove 14 is opened inside the screw cap 13, and the outer surface of the screw cap 13 is connected to the protrusion 15.

[0026] During specific use, when the protective cover 8 is removed for placement, the screw cap 13 is twisted to separate the screw cap 13 from the second surface thread 11 through the second thread groove 12, so that the screw cap 13 can be removed. At this time, the screw cap 13 is screwed into the first surface thread 7 through the second thread groove 12, so that the position of the screw cap 13 can be fixed at the other end of the protective cover 8, so that the screw cap 13 can cover the opening on the protective cover 8.

[0027] Preferably, the protective cover 8 is threadedly connected to the first thread groove 6 through the first surface thread 7 , and the size of the protective cover 8 matches the size of the tube body 4 .

[0028] During specific use, the protective cover 8 can be screwed into the first thread groove 6 through the first surface thread 7, so that one end of the protective cover 8 is connected to the connecting block 5, thereby shielding the tube body 4 inside the protective cover 8.

[0029] Preferably, the sealing ring 9 forms a clamping structure with the connecting block 5 through the first clamping groove 10 .

[0030] During specific use, when the protective cover 8 is screwed into the first thread groove 6 through the first surface thread 7, the sealing ring 9 on the protective cover 8 will be driven to move to the first card groove 10, allowing the sealing ring 9 to be elastically engaged in the first card groove 10, thereby increasing the sealing between the protective cover 8 and the connecting block 5.

[0031] Preferably, the screw cap 13 is threadedly connected with the second surface thread 11 or the first surface thread 7 through the second thread groove 12 .

[0032] During specific use, the screw cap 13 can be screwed onto the second surface thread 11 through the second thread groove 12, so that the position of the screw cap 13 is fixed at one end of the protective cover 8. When the screw cap 13 is screwed onto the first surface thread 7 through the second thread groove 12, the position of the screw cap 13 will be fixed at the other end of the protective cover 8, so that the screw cap 13 can cover the opening at the other end of the protective cover 8.

[0033] Preferably, the sealing ring 9 forms a clamping structure with the screw cap 13 through the second clamping groove 14 , and the protrusions 15 are distributed in a ring array on the outer surface of the screw cap 13 .

[0034] During specific use, when the screw cap 13 is screwed onto the first surface thread 7 through the second thread groove 12, the sealing ring 9 on the protective cover 8 will move to the second card groove 14 on the screw cap 13, so that the sealing ring 9 can be engaged in the second card groove 14, thereby increasing the sealing between the screw cap 13 and the protective cover 8. The protrusions 15 are distributed in a ring array on the outer surface of the screw cap 13, so that when the operator screws the screw cap 13, the friction between the operator's hand and the screw cap 13 can be increased.

[0035] Working principle: When using the wireless ureteroscope with an anti-blocking structure, when the wireless ureteroscope is placed, one end of the protective cover 8 is screwed into the first thread groove 6 on the connecting block 5 through the first surface thread 7, which will drive the sealing ring 9 on the protective cover 8 to move to the first card groove 10, allowing the sealing ring 9 to be elastically engaged in the first card groove 10, thereby increasing the sealing between the protective cover 8 and the connecting block 5. In this way, the position of the protective cover 8 can be fixed on the connecting block 5, so that the protective cover 8 can protect and shield the tube body 4 to prevent the open end of the tube body 4 from being exposed to the environment, causing debris to enter the open end of the tube body 4 and cause the tube body 4 to be blocked. When the wireless ureteroscope needs to be used, it is only necessary to twist the protective cover 8 to allow one end of the protective cover 8 to pass through the first surface thread again. 7 is separated from the first thread groove 6, so that the protective cover 8 can be disassembled, the tube body 4 is exposed again, and the wireless ureteroscope can be used normally. The unscrewed protective cover 8 needs to be placed. At this time, the screw cover 13 is twisted to separate the screw cover 13 from the second surface thread 11 through the second thread groove 12, so that the screw cover 13 can be disassembled. At this time, the screw cover 13 is screwed into the first surface thread 7 through the second thread groove 12, so that the position of the screw cover 13 can be fixed at the other end of the protective cover 8. At this time, the sealing ring 9 on the protective cover 8 will also be engaged into the second card groove 14 on the screw cover 13, thereby increasing the sealing between the screw cover 13 and the protective cover 8, so that the screw cover 13 can cover the opening on the protective cover 8 to prevent debris from entering the inside of the protective cover 8 from the opening when the protective cover 8 is placed.

[0036] 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.
