The invention discloses a knife switch chain lifting device. The device comprises a mounting base and a clamping device. An adjusting handle device grasps a telescopic rod with hands to enable force to flow out; the telescopic rods are prevented from being completely pulled out through an internal limiting plate; the fixing bolt is rotated, screwed and fixed; when the telescopic rod is pulled out,the fixed rotating shaft drives the fixed knife switch and the inlaying groove to be closed in a relatively labor-saving manner; after completion, the hand grasps the telescopic rod to push the telescopic rod to shrink into the sleeve, and the fixing bolt is rotated and screwed again; the length area of the adjusting handle device is reduced; a worker is not easy to touch when working; the beneficial effects are that through the adjusting handle device, when the anchor chain is clamped, the telescopic rod is pulled out, the fixing knife switch is driven to clamp and fix the anchor chain in the wedge-shaped groove through fixing of the fixing bolt, the telescopic rod is pushed and contracted into the sleeve after clamping is completed, then the fixing bolt is rotated and tightened again, the length area of the adjusting handle device is reduced, and a worker is not prone to making contact with the adjusting handle device.

    本发明公开了一种闸刀擎链器,包括安装座和卡接装置,本发明调节手柄装置徒手抓住伸缩杆向外使力流出,通过内部限位板防止伸缩杆全部拉出,再将固定螺栓转动拧动固定,通过将伸缩杆拉出使通过固定转轴带动固定闸刀与镶嵌槽闭合时相对省力,完成后手抓住伸缩杆推动收缩进套筒中再重新将固定螺栓转动拧紧,使其减小调节手柄装置的长度面积,工作人员进行工作时不易与其发生触碰,有益效果是通过调节手柄装置,在进行锚链卡接时将伸缩杆拉出通过固定螺栓固定带动固定闸刀将锚链卡住固定在楔形凹槽中,完成后将伸缩杆推动收缩进套筒中再重新将固定螺栓转动拧紧减小调节手柄装置的长度面积,使工作人员不易与其发生触碰。
