Mousetrap with continuous mousing capability
The invention relates to a mouse killing tool and in particular relates to a mousetrap with a continuous mousing capability. The mousetrap is structurally characterized by consisting of a mouse storage bin and a mouse guiding-in channel, wherein the mouse storage bin and the mouse guiding-in channel are fixed by buckles in the connection process to form a whole body and are very easy to connect and disconnect; and a seesaw is arranged in the mouse guiding-in channel, wherein the specific gravity of the seesaw is large in front part and small in rear part, a natural state of the seesaw is in a mode that the front part of the seesaw is bent over and the rear part of the seesaw is lift, which can ensure that two sides of the mouse guiding-in channel are completely isolated by virtue of the natural state. A functional principle of the mousetrap for mousing is as follows: when a mouse enters the mouse guiding-in channel and passes through the seesaw, the natural state of the seesaw changes caused by the mouse weight and is changed into a mode that the front part of the seesaw is lift and the rear part of the seesaw is bent over, the mouse drops to the other side of the mouse guiding-in channel, and then the seesaw automatically returns to the original state, namely the front part of the seesaw is bent over and the rear part of the seesaw is lift, therefore, the retreat route of the mouse is automatically cut off and the mouse is further confined in the mouse storage bin to achieve the purpose of catching the mouse.
