[0040] Working principle: when assembling, the hose 6 is sleeved on the outer wall of the metal connecting pipe 3. Since the outer wall of the metal connecting pipe 3 is fixedly connected with the thread ring 4 on the right end, and the inner wall of the hose 6 is provided with a thread groove 7 on the left end, by rotating the hose 6, the thread ring 4 is threadedly connected with the thread groove 7. During the thread connection, on the one hand, it plays a preliminary fixing role, ensuring the relative position stability of the hose 6 and the metal connecting pipe 3 in the axial direction. At the same time, the outer wall of the right end of the metal connecting pipe 3 is fixedly connected with a plurality of inclined clamping blocks 5 at equal intervals around, and a plurality of inclined grooves 8 are provided in the inner wall of the hose 6 at equal intervals in the middle. With the rotation of the hose 6 on the metal connecting pipe 3, the plurality of inclined clamping blocks 5 are gradually clamped into the corresponding inclined grooves 8, and the clamping connection of the inclined clamping blocks 5 and the inclined grooves 8 further enhances the connection stability between the hose 6 and the metal connecting pipe 3. This clamping structure can effectively prevent the hose 6 from moving or rotating axially during use. When the entire fixing structure is assembled, the insertion pipe 1 plays a guiding and supporting role during use, allowing the hose 6 to be smoothly inserted into the detection site. The detection head 9 connected to the right end of the hose 6 carries the camera 10 deep into the target area for detection. The camera 10 transmits the collected image information out for the operator to observe and analyze.

[0041] Furthermore, when installing, the mounting ring 201 is pushed into the mounting groove 204 on the right side of the hose 6. The fixed ball 202 on the left side of the mounting ring 201 is protruding on the left side of the mounting ring 201. During the pushing process of the mounting ring 201, the fixed ball 202 is first extruded by the inner wall of the mounting groove 204 and shrinks into the recess 203. As the mounting ring 201 continues to advance, when the fixed ball 202 reaches the position of the ball fixing groove 205 on the left side of the inner wall of the mounting groove 204, the fixed ball 202 loses the extrusion force and pops out and clamps into the ball fixing groove 205 under the action of its own elasticity. The cooperation of the plurality of fixed balls 202 and the plurality of ball fixing grooves 205 ensures the stability of the installation.
