The invention discloses a grabbing mechanism. The grabbing mechanism comprises a first tube body, a hook claw assembly, a plurality of first positioning pieces and one or more second positioning pieces; at least part of the hook claw assembly is located in the first tube body, and the hook claw assembly can rotate relative to the first tube body; the multiple first positioning pieces are arrangedat the bottom of the first tube body in the circumferential direction of the first tube body at intervals, and all the first positioning pieces can move in the axial direction of the first tube body;and the one or more second positioning pieces are located above the multiple first positioning pieces and rotate synchronously with the hook claw assembly, when the multiple first positioning pieces are in a free state, gaps are formed between the first positioning pieces and the second positioning pieces, and when parts of the multiple first positioning pieces are jacked and then move upwards, the parts of the first positioning pieces make contact with at least parts of the second positioning pieces to limit rotation of the second positioning pieces and the hook claw assembly. According to the technical scheme, the operation accuracy of the grabbing mechanism can be improved, the structure is simple, and the grabbing mechanism can be suitable for a narrow space after being miniaturized.

    本发明公开了一种抓取机构,包括:第一筒体;钩爪组件,至少部分位于第一筒体内,钩爪组件可相对于第一筒体转动;多个第一定位件,沿第一筒体的周向间隔设置在第一筒体的底部,各第一定位件沿第一筒体的轴向可移动;至少一个第二定位件,位于多个第一定位件的上方并与钩爪组件同步转动,当多个第一定位件处于自由状态时,第一定位件与第二定位件之间具有间隙,当多个第一定位件中的部分被抵顶后向上移动时,该部分的第一定位件与第二定位件中的至少部分接触,以限制第二定位件和钩爪组件的转动。本发明的技术方案能够提高抓取机构的操作准确性,并且结构简单,小型化后可适用于狭小空间。
