The housing 2 is provided with an opening slot 201 corresponding to the driving gear 401, and the driving gear 401 is rotatably connected to the opening slot 201; the housing 2 forms a receiving cavity for placing the main body 1, and the end of the main body 1 can slide along the receiving cavity; in use, an operator rotates the driving gear 401, and the driving gear 401 drives the driven rack 402 engaged therewith to move, so as to drive the main body 1 to move along the length direction of the housing 2, thereby realizing the extension of the main body 1 in the length direction and realizing the adjustment of the length direction of the detector.
[0035] Specifically, to achieve the stability during the adjustment of the length direction of the main body 1, a guide rail 104 is provided on the main body 1, and a guide rail groove is provided on the housing 2 corresponding to the guide rail 104. The guide rail 104 is disposed in the guide rail groove and can be slidably connected along the guide rail groove. Preferably, two guide rails 104 are provided, and the two guide rails 104 are arranged side by side.

When the adjusting assembly moves, the handwheel can be lifted upward, and the bottom end of the connecting rod is not in contact with the driven rack 402 at this time. After the adjustment is completed, the bottom end of the connecting rod abuts against the tooth groove of the driven rack 402, so as to realize the limiting function of the main body 1; an inclined surface matching the tooth groove of the driven rack 402 is formed at the bottom end of the connecting rod, which can make the bottom end of the connecting rod more stably engaged in the tooth groove of the driven rack 402.
[0037] Specifically, the detector further includes a panel 9. When the detector is in use, since the detector panel 9 is directly connected to the main body 1, it is easy for the main body 1 and the panel 9 to be not tightly sealed, resulting in water entering the interior of the detector and damaging the internal components of the detector. Therefore, a drainage structure is provided on the main body 1 and the panel 9. The drainage structure includes a first drainage groove 105 and a second drainage groove 901. The first drainage groove 105 is provided on the main body 1, and the second drainage groove 901 is provided on the panel 9.

The liquid in the drainage structure can be discharged from the first drainage groove 105.
[0038] After the components inside the detector are installed, the panel 9 and the main body 1 are pressed tightly by the stainless steel plate 5. Since the bottom surface of the panel 9 is a silica gel surface, the main body 1 and the panel 9 are hermetically connected. When the sealing performance between the detector panel 9 and the main body 1 is ensured, the liquid flows into the drainage structure formed by the first drainage groove 105 and the second drainage groove 901. When the detector is taken out of the liquid, the liquid can flow out of the detector through the drainage hole 107, so as to ensure that all the liquid entering the detector can be discharged, realizing the discharge of the liquid while ensuring the sealing of the detector, and thus not affecting the normal operation of the detector.
