Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 3, the present embodiment includes a sleeve 3, a set of support seats is disposed on an outer side surface of the sleeve 3, a limiting plate 15 is disposed on an outer side of each support seat, a support rod 12 is mounted in each support seat through a shaft, the support rod 12 is used for supporting the sleeve 3, and an opening angle of the support rod 12 is limited by the limiting plate 15, so that the sleeve 3 is stably positioned.

In this embodiment, two sides of the lower portion of the inner surface of the sleeve 3 are respectively provided with a groove, a guide rod 4 is respectively installed between the top and the bottom of each groove, a sliding block 5 is sleeved on each guide rod 4, and a heavy hammer 13 is connected below each sliding block 5 through a flexible wire 8 for judging the vertical condition of sampling.
