一种贴片式高耐磨镶齿滚刀

Abstract

本实用新型公开了一种贴片式高耐磨镶齿滚刀，涉及镶齿滚刀技术领域，包括：刀圈，所述刀圈的内部滑动连接有驱动杆，所述驱动杆的内壁一侧滑动连接有滑动柱，所述滑动柱的一端转动连接有螺杆，所述驱动杆的一侧中部贯穿开设有螺纹孔，所述螺杆在所述螺纹孔内螺纹连接，所述滑动柱的外表面转动连接有多个推拉杆。本实用新型通过将刀圈套在驱动杆上，转动转动杆，螺杆沿着驱动杆开设的螺纹孔螺纹移动，推动滑动柱移动，多个推拉杆同时发生转动，将多个升降板同时相互远离，将固定杆卡接在安装孔内，对刀圈进行固定安装，此结构简单，操作方便，可快速将驱动杆与刀圈组装，提高镶齿滚刀安装和拆卸时的便利性。
