[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0019] Please refer to Figures 1-5The utility model provides a technical scheme: a sampling device for dairy product detection, including cylinder 1, rubber lining sleeve 7, jacking sleeve 9 and cylinder cover 12, the top of cylinder 1 is equipped with storage groove 3 and ring groove 8 with the same center, cylinder cover 12 is sleeved on the outer cylinder wall of the top of cylinder 1, the inner bottom of storage groove 3 is fixedly installed with fixed plate 4 through bolt, the top of fixed plate 4 is fixedly connected with tension spring 5, the other end of tension spring 5 is fixedly connected with stroke plate 6, the top of stroke plate 6 is fixedly connected with rubber lining sleeve 7, the other end of rubber lining sleeve 7 is fixedly connected with the inner wall of storage groove 3,

[0020] The inside of ring groove 8 is slidably connected with jacking sleeve 9, the top of jacking sleeve 9 is in contact with rubber lining sleeve 7, and the bottom of jacking sleeve 9 is fixedly connected with connecting plate 10, and the other end of connecting plate 10 is slidably connected through the bottom of cylinder 1.

[0021] The outer circular wall of the top of stroke plate 6 and the inner top wall of storage groove 3 are both provided with annular grooves corresponding to rubber lining sleeve 7, and the annular grooves can effectively make the connection of rubber lining sleeve 7 with stroke plate 6 and storage groove 3 more stable.

[0022] The outer wall of the bottom of cylinder 1 is slidably connected with sliding sleeve 11, one end of connecting plate 10 extending out of cylinder 1 is connected with sliding sleeve 11, and sliding sleeve 11 can make connecting plate 10 more convenient and comfortable when jacking.
