The fixing rod 6 passes through the sliding plate 8 and is fixedly connected with it. Both ends of the first spring 7 are fixedly connected with the fixing frame 4 and the sliding plate 8 respectively.

[0027] Among them, the multiple fixing rods 6 on the inner side of the fixing frame 4 can guide and limit the sliding plate 8, and the first spring 7 on the outer side of the fixing rod 6 can support the sliding plate 8 upward, and then the sliding plate 8 drives the sampling ball 9 at the bottom of the sliding rod 5 to move upward away from the guide tube 1.
