Description

TECHNICAL FIELD The present invention relates to a tool for catching pests when covered with snow.

Conventional vermin catching tools basically consist of a tread, a loop-shaped catching wire, and a catching wire interlocking mechanism that interlocks the lowering (falling) operation of the tread with the diameter-reducing operation of the catching wire.
When a vermin steps on the tread, the loop-shaped catching wire is reduced in diameter through the catching wire interlocking mechanism as the tread moves down, thereby catching the legs of the vermin (for example, Patent Document 1).
