when the pressing plate 29 slides downwards, the pressing plate 29 is pressed on the top of the sliding cavity 43, so that the protection pad 45 contacts the bottom wall of the pressing plate 29 to play a role in protection, and the problem of abrasion caused by contact between the end part of the locking piece 23 and the bottom wall of the pressing plate 29 is avoided; when the pressing plate 29 passes over the locking piece 23, the locking piece 23 slides out to clamp the pressing plate 29, in the clamping process, the problem of abrasion damage to the pressing plate 29 is easily caused, when the guide rod 31 slides downwards, the guide block 42 is pressed at the end part of the protection pad 45 by the downward movement of the push rod 41, the protection pad 45 is subjected to downward force sliding, the sliding plate 44 presses the elastic sheet 47 to generate elastic force, when one end of the sliding plate 44 slides downwards, the air bag 48 is pressed, air in the air bag 48 is transmitted to the inside of the protection air belt 491 through the air pipe 49, the protection air belt 491 is expanded to be closely attached to the clamping part of the locking piece 23 and the pressing plate 29, the protection effect of the locking piece 23 is improved, and the problem of abrasion to the pressing plate 29 is avoided; when the probe mounting bracket 15 needs to be disassembled to overhaul and replace the detection probe 17, the pull ring 28 is pulled, so that the pull ring 28 pulls the pull rod 27 to slide towards the side end, the pull rod 27 pulls the clamping block 25 to stretch into the cavity 22, then the supporting plate 33 generates elasticity to push the second spring 34 to slide upwards, the second spring 34 pushes the pressing plate 29 to slide upwards, the pressing plate 29 is made to pop up to take out the probe mounting bracket 15, the detection probe is convenient for a worker to replace, and when the guide block 42 slides upwards, the elastic piece 47 generates elasticity to push the sliding plate 44 to reset, so that the next installation and disassembly of the worker are convenient; because the end of the locking piece 23 is semi-arc, the pressing plate 29 can conveniently press the locking piece 23, and the problem of locking can not occur.
