When the probe is not in use, the protective cover 13 is placed on one side of the probe 2, and the camera 3 and the lighting lamp 4 on the inner side of the probe 2 are protected by the protective cover 13 to prevent the camera 3 and the lighting lamp 4 from being damaged.
[0025] As a further improvement of the utility model, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the adjustment mechanism includes a fixing plate 11 fixedly connected to the probe 2, the inner side of the fixing plate 11 is rotatably connected to a connecting shaft 9, and the connecting shaft 9 is fixedly connected to a connecting rod 12, the other end of the connecting shaft 9 is fixedly connected to a take-up wheel 8, the outer side of the take-up wheel 8 is wound with a pull rope 7, and one end of the pull rope 7 is fixedly connected to the take-up wheel 8, and the other end of the pull rope 7 is fixedly connected to a slider 6. When the protective cover 13 needs to be flipped away from one side of the probe 2, the staff presses the slider 6 with a finger to move the slider 6 pulling the pull rope 7. At the same time, the movement of the pull rope 7 will also cause the take-up wheel 8 and the connecting shaft 9 to rotate counterclockwise with the connecting rod 12, and then the connecting rod 12 rotates counterclockwise with the protective cover 13 until the protective cover 13 is flipped to one side of the probe 2.
[0026] As a further improvement of the utility model, Figure 4 As shown, a torsion spring 10 is arranged between the connecting rod 12 and the fixing plate 11, and the torsion spring 10 is sleeved on the outside of the connecting shaft 9. When the probe 2 is not in use, the staff pushes the slider 6, and at the same time, under the torsion force of the torsion spring 10, the connecting rod 12 rotates clockwise through the connecting shaft 9 with the take-up wheel 8, and at the same time, the take-up wheel 8 will also reel in the pull rope 7 until the protective cover 13 is on one side of the probe 2.

Under the pulling force of the spring 16, the clamping head 15 can be tightly clamped with the guide shaft 5 through the clamping groove 17 to ensure that the slider 6 will not slide along the guide shaft 5 under the action of the torsion spring 10.
[0029] Working process: when the probe 2 is not in use, the staff pushes the slider 6, and at the same time, under the torsion force of the torsion spring 10, the connecting rod 12 rotates clockwise with the take-up wheel 8 through the connecting shaft 9, and at the same time, the take-up wheel 8 also reels the pull rope 7 until the protective cover 13 is on one side of the probe 2. The protective cover 13 protects the camera 3 and the lighting lamp 4 inside the probe 2 to prevent the camera 3 and the lighting lamp 4 from being damaged; when the probe 2 needs to be used, the staff presses the slider 6 with their fingers to move the slider 6 pulling the pull rope 7, and at the same time The movement of the pull rope 7 will also cause the take-up wheel 8 and the connecting shaft 9 to rotate counterclockwise with the connecting rod 12, and then the connecting rod 12 will rotate counterclockwise with the protective cover 13 until the protective cover 13 is flipped to one side of the probe 2. After the protective cover 13 is flipped over from one side of the probe 2, the clamping head 15 can be tightly clamped with the guide shaft 5 through the clamping groove 17 under the pulling force of the spring 16, ensuring that the slider 6 will not slide along the guide shaft 5 under the action of the torsion spring 10, ensuring that the protective cover 13 will not affect the normal use of the probe 2 during use.
