The invention provides a labor-saving window breaking device fixed on a tempered glass vehicle window. The device is characterized in that a ferrule is arranged in the middle section of a main rod, asleeve is arranged in the ferrule, and oblique teeth are arranged at the tail of the main rod. A strong spring sleeves a firing pin rod. One end of the strong spring abuts against a firing pin base, and the other end of the strong spring abuts against the lower portion of the top face of an inner cavity of the sleeve. The tail of a firing pin penetrates out of an inclined plane through hole and cannot enter the inner cavity of the sleeve under the control of a limiting ring. Under the action of the strong spring and the inclined plane through hole, the head of the firing pin always leans against the side, provided with an inclined raised line, of the inner cavity of the sleeve. A spring ring sleeves the outside of the strong spring. One end of the spring ring abuts against the rear face ofa firing pin sleeve, and the other end of the spring ring abuts against the lower portion of the top face of the inner cavity of the sleeve. After the firing pin sleeve is arranged in the inner cavity of the sleeve, the front end part of the firing pin sleeve is exposed out of the inner cavity of the sleeve under the action of the spring ring and a limiting nail. More than ten kilograms of external force is applied to the firing pin sleeve towards the interior of the inner cavity of the sleeve, and the firing pin sleeve can be extruded to move towards the interior of the inner cavity of the sleeve. The device can easily crush tempered glass.
固定在钢化玻璃车窗上的省力型破窗装置,其特征在于,主杆中段设置有套圈,套圈内设置有套筒,主杆的尾部设置有斜齿;强力弹簧套在撞针杆上,强力弹簧的一端顶在撞针座上,另一端顶在套筒内腔的顶面下;撞针尾穿出斜面通孔被限位圈控制不能进入套筒内腔内;撞针头在强力弹簧与斜面通孔的作用下,始终靠向套筒内腔设置有斜凸条的一方;弹簧圈套在强力弹簧之外,弹簧圈的一端顶在撞针套筒的后面,另一端顶在套筒内腔的顶面下;撞针套筒装入套筒内腔后,在弹簧圈与限位钉的作用下,撞针套筒的前端部分暴露在套筒内腔外;对撞针套筒朝套筒内腔内施以十公斤以上的外力,能将撞针套筒朝套筒内腔中挤压移动。本发明能够轻松破碎钢化玻璃。
