AI Technical Summary

Technical Problem

Existing spring-loaded mouse clips have difficulty controlling the holding depth of the trigger hook, leading to problems such as accidental triggering or insensitivity during deployment.

Method used

It adopts an anti-mistake triggering mechanism, which converts changes in bait weight into the lifting and lowering action of the anti-mistake pressing block through a lever component, realizing the linkage between bait weight monitoring and trigger locking, ensuring that it locks when there is enough bait and automatically triggers when there is not enough bait.

Benefits of technology

It achieves safe locking and high-sensitivity capture when bait is plentiful, avoids false triggering caused by slight disturbances, improves safety and sensitivity, and enhances cleaning convenience through a removable collection tray.

Abstract

本发明公开了一种弹簧式鼠夹，涉及捕鼠器具领域，包括底座、上夹体、诱饵座与防误触发机构，底座为前端带有一排前齿的槽型壳体，底座内侧中部纵向设置转轴座以及转动安装于转轴座上的转杆，底座靠近前齿的位置开设安装孔；上夹体呈T形板状结构，上夹体前端设有与前齿配合的夹齿，上夹体下端可转动套装于转杆上，转杆上套设有扭簧，扭簧中间装于底座底壁、其左右两端分别压抵于上夹体下侧，以驱动上夹体向前齿方向弹起，上夹体顶侧开设有扣槽；该种弹簧式鼠夹，通过设置力矩放大杠杆式防误触发机构，依靠饵料自重实现待机锁止，有效解决传统鼠夹易误触、灵敏度差、稳定性不足的问题，兼顾使用安全与精准捕鼠效果。
