Then, when transporting, just hold the U-shaped handle 14 by hand, which makes transportation very convenient. When in use, take off the top cover 4. , turn the knob 13, the screw rod 12 rotates to make the lifting block 15 rise, and the curved rod 16 makes the connecting plate 17, the connecting plate 2 21 and the instrument body 2 move up, so that the instrument body 2 is moved out of the protective shell 1 for detection, and it is very stable to hold the U-shaped handle 14 by hand. After the detection is completed, the instrument body 2 can be stored again. This is not only more stable during transportation and use, but also the protective shell 1 and the instrument body 2 form a connection structure, which is more convenient and stable than the traditional placement. At the same time, it is not large in size and more convenient to carry.

[0028] The positioning assembly 3 includes two plug plates 31 fixed on the top of the docking plate 17, the plug plates 31 pass through the two openings of the docking plate 21 and fit with the fixed block 32, the fixed block 32 is fixed on the top of the docking plate 21, plug blocks 33 slide in the openings on both sides of the fixed block 32, one side of the plug block 33 is connected to the fixed block 32 by a spring 34, and the fixed block 32 passes through the socket on one side of the plug plate 31, and a toggle block 35 is fixed on the top of the plug block 33, and the toggle block 35 passes through the top of the fixed block 32 and slides in its opening.

[0029] As described above, through the design of the positioning component 3, when the connecting plate 17 and the docking plate 21 are docked, after the connecting plate 17 and the docking plate 21 are fitted together, the plug plate 31 passes through the two openings of the docking plate 21 and fits with the fixing block 32, and the plug block 33 is compressed first, and after reaching the socket position on one side of the plug plate 31, it is automatically reset and inserted into the socket by the spring 34, so that the instrument body 2 is stably connected to the inside of the protective shell 1, and when it needs to be taken out, the two toggle blocks 35 can be moved to drive the plug block 3 to move, which makes disassembly and assembly very convenient, and also increases the stability of holding the U-shaped handle 14 when transporting or using.

[0030] The top of the protective shell 1 is designed with an opening, and there are two convex-shaped limit blocks 19 at both ends of the top. A top cover 4 is installed on the top of the protective shell 1. The limit blocks 19 are inserted through two openings designed on one side of the top cover 4. An operation port 18 is provided at the upper end of the front surface of the protective shell 1. A square slider 52 is inserted into the slot inside the operation port 18. The top surface of the sealing plate 5 is aligned with the top surface of the protective shell 1, and the side surface is attached to the inside of the operation port 18.
