[0025] Please see Figure 2 , Figure 4 , Figure 5The connecting mechanism 8 includes a fixed rod 81, which is fixedly connected inside the cover 6. A first spring 82 is provided on the outside of the fixed rod 81. One end of the first spring 82 is fixedly connected to the slider 83, and the other end of the first spring 82 is fixedly connected to the cover 6. By designing the first spring 82, the force of the first spring 82 can act on the slider 83. The slider 83 is slidably sleeved on the outside of the fixed rod 81. A ball 84 is fixedly connected to one end of the slider 83, and the other end of the ball 84 is fixedly connected to the cover 6. A retaining ball 85 is movably sleeved inside the other end of the slider 83. The retaining ball 85 is movably connected to the cover 6 and to the ventilation mesh 7. A groove 86 is provided inside the ventilation mesh 7, and the retaining ball 85 is movably sleeved inside the groove 86. By designing the groove 86, the retaining ball 85 can roll inside the groove 86. By designing the connecting mechanism 8, it is convenient to disassemble the ventilation mesh 7.

[0026] Please see Figure 1 , Figure 6 The adjusting mechanism 9 includes an arc-shaped groove 91. An arc-shaped groove 91 is formed inside the outer casing 4. An arc-shaped block 92 is slidably fitted inside the arc-shaped groove 91. There are multiple arc-shaped grooves 91, evenly distributed inside the outer casing 4. By designing multiple arc-shaped grooves 91, the arc-shaped block 92 can slide into different positions within the arc-shaped grooves 91. A slide block 93 is slidably fitted onto the outer side of the arc-shaped block 92. The slide block 93 is slidably connected to the outer casing 4. A slide rod 94 is fixedly connected to the outer side of the arc-shaped block 92. The slide rod 94 is connected to the slide block 92... The base 93 is slidably connected, and a second spring 95 is provided on the outside of the slide rod 94. One end of the second spring 95 is fixedly connected to the arc block 92, and the other end of the second spring 95 is fixedly connected to the slide base 93. By designing the second spring 95, the force of the second spring 95 can be applied to the arc block 92. A connecting rod 96 is fixedly connected to the top of the slide base 93, and a connecting rod 97 is hinged to the top of the connecting rod 96. The other end of the connecting rod 97 is hinged to the display screen 5. By designing the adjustment mechanism 9, the viewing angle of the display screen 5 can be easily adjusted.

[0027] The specific implementation process of this utility model is as follows: When in use, by setting the detection mechanism 10 on the back of the detector with the opening facing backward, light pollution from the strong light exposure of the CCD camera 11 can be avoided, and the risk of accidentally touching the cable when operating the display screen 5 can also be avoided; through the action of the ventilation fan 12, the detection cable can be blown away, and the floating dust attached to the surface can be blown away, so as not to affect the detection of the cable. In addition, during the ventilation process, the ventilation net 7 can reduce the amount of dust entering from the outside air, so as to avoid serious dust pollution.

[0028] When it is necessary to disassemble the ventilation screen 7, simply pull the ventilation screen 7 outwards. The ventilation screen 7 and the protective cover 6 will slide relative to each other. The arc surface of the groove 86 inside the ventilation screen 7 will squeeze and push the retaining ball 85. The retaining ball 85 will roll away from the ventilation screen 7. The retaining ball 85 will drive the slider 83 to slide along the fixed rod 81 and squeeze the first spring 82. At the same time, the slider 83 will squeeze the spring ball 84, which will then separate the retaining ball 85 from the groove 86. The ventilation screen 7 can then be pulled out from inside the protective cover 6 for easy disassembly, cleaning and maintenance.

[0029] The display screen 5 displays the working process of the detector and allows for operation control. When the angle of the display screen 5 needs to be adjusted, simply rotate the display screen 5. The display screen 5 will rotate along the outer casing 4, and at the same time, the display screen 5 will pull the connecting rod 97 to move. The connecting rod 97 will deflect, and the connecting rod 97 will pull the slide block 93 to slide upward. The arc block 92 will slide along the arc groove 91 and slide into the slide block 93. The arc block 92 will also drive the sliding rod 94 to move. The arc block 92 will compress the second spring 95, which can separate the arc block 92 from the arc groove 91. After the display screen 5 is adjusted, the elasticity of the second spring 95 will give the arc block 92 a counter-pushing force, which can push the arc block 92 into the arc groove 91 in another position. At this time, the relative position of the slide block 93 and the outer casing 4 can be adjusted and fixed, which facilitates flexible adjustment of the operating angle of the display screen 5 and improves its usage effect.
