Self-adaptive locking steel fork

The utility model relates to a self-adaptive locking steel fork. The self-adaptive locking steel fork is characterized by comprising a main body, a movable part arranged on the main body in a swinging manner, a limiting piece for limiting the swinging position of the movable part and a pressing part movably arranged on the main body, when the pressing part touches the pressing part, the pressing part pulls the limiting piece to be away from the movable part, and the movable part swings to press and limit the pressing part. The problems that in an existing scheme, a steel fork cannot achieve self-locking, a gangster is difficult to control by a single person, the gangster is prone to struggling away, and catching work is not facilitated are solved. 本实用新型涉及自适应锁定钢叉，其特征在于：包括主体、摆动设置在所述主体上的活动部、限制所述活动部摆动位置的限制件和活动设置在所述主体上的按动部；制伏部位碰触到所述按动部时，所述按动部拉动所述限制件远离所述活动部，所述活动部摆动按压限制制伏部位。解决了现有方案中钢叉不能实现自锁，很难实现单人控制歹徒，歹徒容易挣脱，不利于抓捕工作的展开的问题。
