Obstructing device for noxious mollusks

Abstract

The invention discloses an obstructing device for noxious mollusks. The obstructing device for the noxious mollusks is characterized by comprising a main body and at least a metal copper unit; the metal copper unit is arranged on the inner wall surface of the main body; the main body is provided with a hollow rod and an umbrella unit; the hollow rod is provided with a first end, a second end and a shaft hole; the first end and the second end are the top and the bottom of the hollow rod; the hollow rod is also provided with a combination groove; the combination groove which is formed in the second end in an annular mode is communicated with the shaft hole; the shaft hole which is communicated with the first end and the second end can be fixedly formed in the hollow rod in a sleeve mode. The obstructing device for the noxious mollusks has the advantages of effectively preventing snails or slugs climbing upward to achieve improvement of protection of the snails or the slugs and being practical and economic, convenient and practical and applicable to popularization in a wide range.

Description

technical field [0001] The invention relates to a barrier device, in particular to a barrier device for harmful molluscs. Background technique [0002] When using the known blocking device for harmful molluscs, the insect-proof cover provided with the insect-proof box is sleeved on the outer periphery of the rod body through the sleeve hole. Once the wall hangs down, it will fall into the ring groove, so that the barrier in the ring groove can be used to achieve the effect of killing insects. However, since the insects fall into the ring groove and are affected by the barrier and die, after long-term use, too many insect corpses will be accumulated in the ring groove, so that the insect-proof box must be removed and cleaned regularly or irregularly. Cause inconvenience in use. Furthermore, once too many insect corpses are accumulated in the ring groove, the subsequent fallen insects can crawl along these corpses to the passage space, and then climb to the pole body along...

AI Technical Summary

Problems solved by technology

However, since the insects fall into the ring groove and are affected by the barrier and die, after long-term use, too many insect corpses will be accumulated in the ring groove, so that the insect-proof box must be removed and cleaned regularly or irregularly. cause inconvenience in use

Furthermore, once too many insect corpses are accumulated in the ring groove, the subsequent fallen insects can crawl along these corpses to the passage space, and then climb to the pole body along the outer wall of the insect-proof box and the insect-proof cover in sequence. , causing the plants planted above the pole to be gnawed
