Technical Field

[0001] The utility model relates to the technical field of mousetraps, in particular to a novel vole trap for tunnels. Background Art

[0002] At present, most voles are harmful to agriculture, animal husbandry and forestry, especially some species with strong social habit and large population fluctuations. In addition, voles are natural carriers of pathogens of infectious diseases such as tick-borne typhus, tularemia, encephalitis, etc., which are closely related to epidemiology, so it is very necessary to catch and kill voles.

[0003] The existing Chinese patent with announcement number CN106689103B discloses a mousetrap, including a base frame, a vertical frame and a clamping frame. The clamping frame can be opened and closed relative to the base frame. The vertical frame is provided with a ring, a clamping mechanism and a trigger frame from top to bottom. The ring clamps the clamping frame and can move up and down relative to the vertical frame. The ring and the clamping mechanism are tensioned and connected. The clamping mechanism clamps the trigger frame and can rotate vertically relative to the vertical frame. The trigger frame is rotatably connected to the base frame.

[0004] With respect to the above-mentioned related technologies, it is found that most of the existing mousetraps have large structural dimensions and are not suitable for installation in small-sized vole holes. Utility Model Content

[0021] Reference Figure 1 , Figure 2 and Figure 3 As shown, a new type of vole trap for tunnels includes a first base frame 1, a central axis 2 and a second base frame 3. The first base frame 1 and the second base frame 3 are respectively arranged at two ends of the central axis 2. A first clamping frame 4 is arranged above the first base frame 1, and a second clamping frame 5 is arranged above the second base frame 3. The first clamping frame 4 and the second clamping frame 5 are both rotatably connected to the central axis 2, and a composite torsion spring 6 is also installed on the central axis 2 to clamp the first clamping frame 4 and the second clamping frame 5 to each other. A support rod 7 supporting the first clamping frame 4 and the second clamping frame 5 is rotatably installed on the second base frame 3, and a trigger blocking frame 8 matching the head of the support rod 7 is also installed on the first clamping frame 4.

[0022] Reference Figure 1 , Figure 2 and Figure 3 As shown, the composite torsion spring 6 includes a coil spring 61 and a middle frame 62, wherein the coil spring 61 is arranged at both ends of the middle frame 62, and the coil spring 61 and the middle frame 62 are integrally formed. One end of the coil spring 61 is connected to the middle frame 62, and the other end of the coil spring 61 is provided with an anti-drop hook 611, and the anti-drop hook 611 is integrally formed with the coil spring 61. The middle frame 62 includes a short rod 621 and a long rod 622, wherein the long rod 622 is arranged at both ends of the short rod 621, and the long rod 622 is integrally formed with the short rod 621. The inner angle between the short rod 621 and the long rod 622 is 60°, and the shape of the middle frame 62 can be ensured by limiting the angle between the short rod 621 and the long rod 622. The shape of the anti-drop hook 611 is arc-shaped, and the anti-drop hook 611 is designed to be arc-shaped to ensure better locking and prevent from falling off.

[0023] Reference Figure 1 , Figure 2 and Figure 3As shown, the support rod 7 includes a spiral portion 71, a straight rod portion 72 and a bent rod portion 73, and the straight rod portion 72 and the bent rod portion 73 are integrally formed and arranged at both ends of the spiral portion 71. The structural setting of the support rod 7 ensures that the straight rod portion 72 and the bent rod portion 73 at both ends of the spiral portion 71 are engaged and locked with the first clamping frame 4 and the second clamping frame 5 respectively.

[0024] Working principle: When needed, the first clamping frame and the second clamping frame are flipped open to overcome the torque, and then the straight rod part on the support rod is engaged with the trigger block frame, and then one end of the trigger block frame is inserted into the vole hole. When the vole comes out, it touches the trigger block frame, and the trigger block frame slides off the support rod, so that the support rod can release the lock of the first clamping frame and the second clamping frame, and then achieve quick clamping under the action of the composite torsion spring.
