摘要： A gopher trap has a wire base frame with elongate limbs connected by a cross member at a distal end of the trap. Wire jaws are pivotly mounted on the respective limbs adjacent the distal end. The limbs are connected at the proximal end of the trap by a transverse pin which carries a pivotal jaw actuator plate and a pivotal trigger pan. The trigger pan is attached to an elongate trigger rod which extends under the length of the actuator plate to the distal end of the trap. The actuator plate embraces the respective jaws for opening and closing same and is spring urged away from the base frame to bias the jaws into closed position. The trap may be set by depressing the actuator plate and allowing the trigger pan to pivot forwardly so that the distal end of the trigger rod can engage under the cross member at the distal end of the base frame. The trap is sprung when a rodent pushes the trigger pan rearwardly and disengages the trigger rod from under the cross member.
摘要翻译：地沟捕鱼器具有线底框架，其具有通过在捕集器的远端处的横向构件连接的细长肢体。电线钳枢轴安装在邻近远端的相应肢体上。四肢通过横向销连接在收集器的近端，承载枢转爪致动器板和枢转式触发盘。触发盘附接到在致动器板的长度下延伸到陷阱的远端的细长触发杆。致动器板包围相应的钳口以打开和关闭相应的钳口，并且弹簧被推离离开基座，以将钳口偏压到关闭位置。可以通过按下致动器板并允许触发盘向前枢转来设置陷阱，使得触发杆的远端能够接合在基架的远端处的横向构件下方。当啮齿动物向后推动触发盘并将触发杆从横梁下方脱离时，陷阱被弹起。
