Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a portable liquid hazardous materials detector, comprising: a detector body 1, a protective sleeve 2 snapped onto the outer bottom of the detector body 1, a piercing rod 6 connected to the middle of the bottom of the detector body 1, a detection body 3 slidably connected inside the detector body 1, a sampling rod 5 threadedly connected to the bottom end of the detection body 3, a transverse limiting groove 104 formed on the bottom of the rear side wall of the detector body 1, a limiting plate 7 inserted into the limiting groove 104, a U-shaped groove formed on the outer side wall of the limiting plate 7, a display screen 101 fixedly installed on the front side wall of the detector body 1, and a sliding guide groove formed on the rear side wall of the detector body 1. 102. A connecting slot 103 is provided at the middle of the left and right sides of the bottom of the main body 1 of the detector. A triangular groove is provided at the top of the connecting slot 103. Specifically, the limiting slot 104 cooperates with the limiting plate 7 to limit the position of the puncture rod 6 and prevent the puncture rod 6 from accidentally falling off when not in the detection state. The sliding guide groove 102 provides guidance for the sliding guide rod 301 to ensure the stable sliding of the detection body 3. The connecting slot 103 forms a solid engagement with the connecting block 201 of the protective sleeve 2 through the triangular groove, which not only facilitates the quick installation and removal of the protective sleeve 2, but also prevents it from falling off. The display screen 101 can intuitively display the detection data and improve the convenience of operation.

[0027] The protective sleeve 2 has a cylindrical structure. Connecting blocks 201 are fixedly connected to the top left and right sides of the protective sleeve 2. Triangular protrusions are fixedly installed on the top of the opposite side walls of the two connecting blocks 201. The triangular protrusions of the connecting blocks 201 are engaged in the triangular grooves of the connecting slots 103 on the bottom side of the detector body 1. Specifically, the cylindrical protective sleeve 2 can completely cover the puncture rod 6 and the sampling rod 5 when not in use, to prevent sharp parts from scratching the user or being contaminated by the outside world. The engaging structure of the triangular protrusions and grooves enables the protective sleeve 2 to be quickly disassembled and assembled from the detector body 1, and the connection is stable and will not accidentally come off during carrying. At the same time, the triangular structure can distribute the force and improve the durability of the connection.

[0028] The detection body 3 is cylindrical. A sliding guide rod 301 is fixedly connected to the top of the rear side wall of the detection body 3. The sliding guide rod 301 is slidably connected in a sliding guide groove 102 opened in the rear side wall of the detection body 1. A connecting main rod 302 is fixedly connected to the middle of the bottom of the detection body 3. The connecting main rod 302 is slidably connected to the bottom of the detection body 1. A reset spring 4 is sleeved on the outside of the bottom connecting main rod 302 of the detection body 3 in the detection body 1. The detection body 3 and the sampling main rod 5 are electrically connected. Three sampling slots 501 are equally spaced on the bottom of the outer side wall of the sampling main rod 5. The side walls of the sampling slots 501 are semi-closed. A detection probe is located in the middle of the sampling main rod 5 surrounding the sampling tank 501. Specifically, the sliding guide rod 301 and the sliding guide groove 102 work together to limit the sliding trajectory of the detection body 3, ensuring the stability of the sampling and detection process. The reset spring 4 can automatically drive the detection body 3 to reset after the detection is completed, without manual operation, improving the convenience of use. The three semi-enclosed sampling tanks 501 can hold multiple liquid samples at the same time, increasing the sampling volume while preventing sample spillage. With the middle detection probe, multi-area sampling and detection can be completed quickly, improving detection efficiency and accuracy. The electrical connection between the detection body 3 and the sampling main rod 5 enables real-time transmission and processing of sampling data.

[0029] The puncture rod 6 is sleeved on the outside of the main rod 302 and the sampling rod 5 at the bottom of the detection body 3. The top outer side of the puncture rod 6 is fixedly connected to the connecting handle 601. The bottom of the connecting handle 601 is connected to the upper side of the limiting plate 7. Specifically, the puncture rod 6 can puncture the sealed liquid container during the test without manually opening the container, reducing operation steps and avoiding sample leakage. The connecting handle 601 is fixed by the limiting plate 7, which makes it easy to replace the puncture rod 6.

[0030] The specific usage and function of this embodiment are as follows:

[0031] When using this portable liquid hazardous materials detector, first remove the protective cover 2 from the bottom of the detector body 1, then pull out the limiting insert 7 from the limiting slot 104 shaft, then insert the connecting handle 601 at the top of the piercing rod 6 into the bottom of the detector body 1, and then insert the limiting insert 7 back into the limiting slot 104 to fix the piercing rod 6. After the piercing rod 6 punctures the sealed container of the liquid to be tested, the detection body 3 moves down under the guidance of the sliding guide rod 301 and the sliding guide groove 102. The sampling slot 501 of the sampling main rod 5 contacts the liquid and is detected through the intermediate detection probe. The detection data is processed by the detection body 3 and displayed on the display screen 101. After the detection is completed, the reset spring 4 drives the detection body 3 and the sampling main rod 5 to reset. Finally, the piercing rod 6 and the sampling main rod 5 are disassembled and replaced respectively.

[0032] Example 2:

[0033] The threaded connection structure between the detection body 3 and the sampling rod 5 is optimized into a quick-release buckle connection. Three elastic buckles are set at the bottom of the connecting rod 302, and buckle grooves are opened at the top of the sampling rod 5. Anti-slip textures are provided on the inner side of the buckles. At the same time, conductive springs are added to the contact surface between the connecting rod 302 and the sampling rod 5 to ensure the stability of the electrical connection.
