The invention relates to the technical field of chain block auxiliary tools, and particularly discloses a chain block lifting height adjuster which comprises a shell and a chain wheel, and a chain groove matched with a chain in shape is formed in the circumferential direction of the chain wheel. The chain wheel is rotationally mounted in the shell through a shaft sleeve; the shaft sleeve is axially provided with a polygonal shaft hole or a polygonal shaft; the device further comprises a machine frame used for limiting the hand pulling chain in the chain groove, a channel allowing the hand pulling chain to penetrate through from top to bottom is formed between the machine frame and the chain groove, and one side of the shell is detachably connected with the machine frame. The lifting device is used in cooperation with a power device, the labor cost is saved, meanwhile, the lifting or descending speed of objects is increased, and the time cost is reduced.

    本发明涉及手拉葫芦辅助工具技术领域,具体公开了一种手拉葫芦起升高度调节器,包括壳体和链轮,链轮周向设有与手拉链条形状相匹配的链槽;链轮通过轴套转动安装在壳体内部,轴套轴向设有多边形轴孔或多边形轴;还包括用于将手拉链条限位于链槽内的机架,机架与链槽之间形成可供手拉链条从上至下穿过的通道,壳体一侧与机架可拆卸连接。本发明通过配合动力装置使用,节约人力成本,同时加快将物品提升或者下降的速度,减少时间成本。
