[0012] 1. In the utility model, by setting an auxiliary device, when it is necessary to sample the food sample, the staff first holds the device through the gripping rod, and then extends the sampling head into the device containing the liquid food sample, and then starts the electric telescopic rod. The electric telescopic rod starts to drive the movable plate to move inside the vertical groove, and the movable plate moves inside the vertical groove to drive the hinged plate to move, and the hinged plate moves to pull the vertical strip plate to move, and the vertical strip plate moves to drive the slide plate to move on the surface of the L-shaped rod. At the same time, the movement of the vertical strip plate also drives the piston to move inside the sampling cylinder, and the movement of the piston inside the sampling cylinder forms a negative pressure vacuum state inside the sampling cylinder. At this time, the air pressure inside the sampling cylinder is lower than the pressure outside the sampling cylinder, and then the food sample is drawn into the interior of the sampling cylinder under the action of the external pressure, and the sampling operation of the food sample is completed. Through the cooperation of the above structure, the sampling speed is fast and the working efficiency is high, which can meet the sampling needs when there are more samples and reduce the labor intensity of the operator.

[0013] 2. In the utility model, by setting a protective device, when the sampling is completed and the sampling head needs to be protected, the second clamp ring is moved first. The movement of the second clamp ring will squeeze the spring, so that the spring is compressed. At the same time, the movement of the second clamp ring also drives the moving rod to move toward the inside of the sleeve. At the same time, the second clamp ring moves away from the sealing cover. The second clamp ring and the sealing cover are separated so that the sealing cover loses its limit. At this time, the sealing cover can be removed and installed inside the mounting groove. Through the cooperation of the above structure, after the sampling work is completed, the sealing cover is used to effectively seal and protect the sampling head, thereby preventing dust in the air from entering the interior of the sampling head when the device is idle, causing pollution to the sampling head.

When the sampling is completed and the sampling head 5 needs to be protected, the second clamp ring 310 is moved first. The movement of the second clamp ring 310 will squeeze the spring 311, so that the spring 311 is compressed. At the same time, the movement of the second clamp ring 310 also drives the moving rod 309 to move toward the inside of the sleeve 308. At the same time, the second clamp ring 310 moves away from the sealing cover 306. The second clamp ring 310 and the sealing cover 306 are separated, so that the sealing cover 306 loses its limit. At this time, the sealing cover 306 can be removed and installed in the installation groove 301. Through the cooperation of the above structure, after the sampling work is completed, the sealing cover 306 is used to effectively seal and protect the sampling head 5, thereby preventing dust in the air from entering the interior of the sampling head 5 when the device is idle, causing pollution to the sampling head 5.
