[0030] After cutting the line pipe, the worker rotates the cover 6 on the surface of the connecting ring 3 to move the synchronous belt claw 7 and the clamping plate 2 together, thereby realizing the separation from the clamping plate 1 5. The rotating action makes the claw 4 separate from the clamping plate 2 8, so that the connecting ring 3 and the cover 6 lose the restriction between them, and then the storage cavity is exposed. At this time, the worker can take out the sampling cotton swab placed in the storage cavity, wipe the attachments inside the pipeline, and after sampling, the worker puts the cotton swab back into the storage cavity and effectively separates it from other sampling cotton swabs through the partition 2, avoiding pollution and improving the purity of the sample. Finally, the worker reconnects the connecting ring 3 and the cover 6 to ensure that the equipment is closed, and the effect of easy installation and disassembly is achieved, solving the problem of easy jamming of traditional threaded connection.

[0031] Reference Figure 1 - Figure 3 The cutting mechanism includes a cutting knife 11 arranged inside the handle 1, the side wall of the cutting knife 11 is fixedly connected with a pressing plate 12, the pressing plate 12 provides pressure during cutting, the side wall of the knife handle 10 is fixedly connected with a connecting rod 13, the side wall of the connecting rod 13 is fixedly connected with a limiting ball 14, the limiting ball 14 is arranged on the left and right sides of the knife handle 10, and is used for fixing the pipeline to ensure that the pipeline does not move during cutting, thereby ensuring the accuracy of cutting. The side wall of the handle 1 is provided with an anti-skid groove 15, which provides better holding force and control feeling for the user, avoids sliding, and improves the safety and comfort during use. The side wall of the handle 1 is provided with a pressing surface 16, and the cutting force is applied by pressing this surface with the fingers, thereby improving the efficiency and convenience of operation.

[0032] When using the device to sample the liquid in the remaining pipeline, the worker holds the handle 1 with the thumb on the top of the pressing surface 16 to ensure the stability of the hand posture and increase the stability of the operation.
