[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, the utility model has the following specific embodiments.

[0027] Example:

[0028] A veterinary sampling device includes a piston cylinder 1 and a sampling tube 5. The piston cylinder 1 has a piston block 11 movably connected to the interior thereof. One end of the outer surface of the piston cylinder 1 is penetrated and connected to a first fixed tube 12 and a second fixed tube 13. The device also includes:

[0029] The handheld frame 2 has a sliding rod 21 fixedly connected to both ends of the handheld frame 2. One end of the two sliding rods 21 is movably connected to a first lifting plate 22. A hand handle 221 is fixedly connected to the top of the first lifting plate 22. A piston rod 222 is fixedly connected to the bottom of the first lifting plate 22. The other end of the sliding rod 21 is fixedly connected to a first spring 211.

[0030] The sampling tube positioning frame 3 has an upper clamping plate 31 fixedly connected to one end of the sampling tube positioning frame 3, a conical sealing plug 311 fixedly connected to the bottom of the upper clamping plate 31, and a lower clamping plate 32 movably connected to the other end of the sampling tube positioning frame 3, a support seat 321 fixedly connected to the top of the lower clamping plate 32, and a second spring 322 fixedly connected to the bottom of the lower clamping plate 32;

[0031] The third fixed tube 4 passes through the sampling test tube positioning frame 3 , and one end of the third fixed tube 4 is fixedly connected to a hose 41 , and one end of the hose 41 is fixedly connected to a pipette head 42 .

[0032] Specifically, one end of the piston rod 222 is fixedly connected to the piston block 11, and the piston rod 222 is connected to the first lifting plate 22 inside the handheld frame 2, so that the handheld frame 2 can be held and the piston block 11 connected to the piston rod 222 can be pulled to move.

[0033] Specifically, the sampling tube 5 is positioned and clamped between the conical sealing plug 311 and the support seat 321, and the conical sealing plug 311 is sealed and connected to the sampling tube 5. The set sampling tube 5 can be clamped between the upper clamping plate 31 and the support seat 321, and the conical sealing plug 311 fixed on the upper clamping plate 31 can be inserted into the opening of the sampling tube 5 for closing.

[0034] Specifically, the other ends of the first fixed tube 12 and the third fixed tube 4 are both connected to the conical sealing plug 311, and the first fixed tube 12 and the third fixed tube 4 are both connected to the sampling tube 5, so that the first fixed tube 12 can suck air into the sampling tube 5, and negative pressure is generated after the sampling tube 5 is sucked in. After the negative pressure inside the sampling tube 5 is generated, air can be sucked to the outside through the connected third fixed tube 4, and then when the pipette head 42 connected to the hose 41 by the third fixed tube 4 is extended into the water sample, the sample can be sucked in.

[0035] Specifically, one end of the first fixed tube 12 and the second fixed tube 13 are both provided with a one-way valve. The one-way valves provided on the first fixed tube 12 and the second fixed tube 13 enable one-way transportation. When the piston block 11 moves upward, the piston cylinder 1 inhales gas in one direction through the first fixed tube 12. When the piston block 11 moves downward, the piston cylinder 1 exhausts gas in one direction through the second fixed tube 13.

[0036] The specific working principle of this utility model is:

[0037] First, pick up the device with one hand through the handheld frame 2, then use the handheld hose 41 to extend the pipette head 42 into the sample to be sampled, and then manually move the first lifting plate 22 upward. The first lifting plate 22 pulls the connected piston block 11 upward through the piston rod 222. When the piston block 11 moves upward, one-way suction is performed through the first fixed tube 12. Since the other end of the first fixed tube 12 is connected to the sampling test tube 5, and the sampling test tube 5 is connected to the hose 41 through the third fixed tube 4, the sample can be input into the internal storage of the sampling test tube 5 through the pipette head 42. The sampling tube 5 can be removed from the sampling tube positioning rack 3 by pressing the sampling tube 5 downward and squeezing the lower clamping plate 32 through the support seat 321. At this time, the top of the sampling tube 5 can be separated from the conical sealing plug 311, so that the sampling tube 5 can be removed from the sampling tube positioning rack 3, and then another sampling tube 5 can be replaced and placed on the sampling tube positioning rack 3 for sampling and storage. The structure is reasonable, convenient for replacing the test tube for sampling, easy operation, and convenient for sampling.
