[0024] Embodiment 1:

[0025] Reference Figures 1 to 5 The automatic sampler comprises a sampler body 100, a sample storage rack 400 is movably connected to the inner side of the sampler body 100, a positioning mechanism 200 is arranged on the outer side of the sampler body 100, and a clamping mechanism 300 is arranged on the top of the sampler body 100;

[0026] The positioning mechanism 200 includes a limit frame 210, which is fixedly connected to the outside of the sampler body 100. A connecting plate 211 is slidably connected to the inner wall of the limit frame 210. A clamping block 220 is fixedly connected to one side of the connecting plate 211. A long plate 222 is fixedly connected to the outside of the connecting plate 211. A first threaded rod 233 is rotatably connected to the outside of the long plate 222. A support block 240 is fixedly connected to the inside of the limit frame 210. A limit block 230 is fixedly connected to the inside of the support block 240.

[0027] In some embodiments, a sliding opening is opened inside the long board 222, and the long board 222 is slidably connected to the outside of the limiting block 230 through the opened sliding opening, so that the long board 222 can be stably limited during the movement of the long board 222.

[0028] In some embodiments, a threaded hole is opened inside the long plate 222, and the long plate 222 is threadedly connected to the outer wall of the first threaded rod 233 through the threaded hole, so that the rotational motion of the first threaded rod 233 is converted into linear motion of the long plate 222, thereby achieving a stable limiting effect.

[0029] In some embodiments, the first threaded rod 233 passes through the support block 240 and rotates. One end of the first threaded rod 233 away from the sampler body 100 is fixedly connected to a torsion block to facilitate the operation and rotation of the first threaded rod 233 .

[0030] In some embodiments, the block 220 penetrates the outside of the sampler body 100 and moves, and the inner side of the block 220 contacts the outer side of the sample rack 400, so that the sample rack 400 can be stably positioned.

[0031] Embodiment 2

[0032] See also Figures 1 to 5 On the basis of the first embodiment, the clamping mechanism 300 further comprises a support plate 310, the support plate 310 is fixedly connected to the top of the sampler body 100, the support plate 310 is internally threadedly connected to a second threaded rod 311, the right end of the second threaded rod 311 is rotatably connected to a first clamping block 320, and the top of the sampler body 100 is fixedly connected to a second clamping block 322, so as to facilitate the stable positioning of the sample loading bottle.

[0033] In some embodiments, the first clamp block 320 is slidably connected to the top of the sampler body 100, and one end of the second threaded rod 311 away from the first clamp block 320 is fixedly connected to a handwheel to facilitate rotating the second threaded rod 311 by shaking the handwheel.

[0034] In actual operation, when the device is used, when the sample rack 400 needs to be positioned, the twist block can be twisted first to drive the first threaded rod 233 to rotate. Since the long plate 222 can slide on the outside of the limit block 230, and the first threaded rod 233 and the long plate 222 are threadedly connected, the rotational movement of the first threaded rod 233 will be converted into a linear movement of the long plate 222. The long plate 222 can drive the block 220 to move in the direction close to the sample rack 400, so that the inner side of the block 220 is in close contact with the outer side of the sample rack 400, thereby stabilizing the position of the sample rack 400 and ensuring the stability of the sample rack 400 during the sampling process. At the same time, the device is easy to operate and use under the action of the twist block, further improving the convenience of operating the device and ensuring that the sampling work can be carried out in some embodiments.

[0035] Then, during use, the staff can place the sampling bottle on the inner side of the second clamping block 322, and then shake the hand wheel to drive the second threaded rod 311 to rotate. Since the second threaded rod 311 and the support plate 310 are threadedly connected, and the first clamping block 320 can be slidably limited at the top of 1, the rotational movement of the second threaded rod 311 can be converted into a linear movement of the first clamping block 320, so that the first clamping block 320 can move close to the outside of the sampling bottle. Therefore, the first clamping block 320 and the second clamping block 322 can cooperate with each other to stably clamp the sampling bottle, thereby ensuring the stability of the sampling bottle during the sampling operation, and will not easily produce displacement and looseness, etc., further improving the practicality of the device.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
