A group of geometric multiplication large-force two-dimensional multi-stage double-connecting-rod levers are arranged on the upper side of a support, multiple stages can be two, three, four, five or more stages, the last stage of lever is connected with a transmission cross rod, and the transmission cross rod is fixedly connected with a left push rod and a right push rod. When the turning rod handle is pushed by hand to drive the geometric multiplication large-force two-dimensional multi-stage double-connecting-rod lever to move leftwards and rightwards, the transmission transverse rod, the right push rod and the left push rod are driven, and then the crowbar handle is pushed to enable the crowbar to prize leftwards. The large-force effect is achieved through the geometric multiplication large-force two-dimensional multi-stage double-connecting-rod lever. The double-connecting-rod longitudinal and transverse two-dimensional arrangement makes full use of space. The invention has the advantages of firm structure and large strength.
一种几何倍增大力二维多级双连杆杠杆撬棍,支架上边设有一组几何倍增大力二维多级双连杆杠杆,多级可以是2、3、4、5或更多级,最后一级杠杆连接设置传动横杆,传动横杆固定连接左右推杆。当手推拐杆把手带动几何倍增大力二维多级双连杆杠杆向左右运行时.带动传动横杆、右左推杆,再推动棍柄使撬棍向左撬动。本发明通过几何倍增大力二维多级双连杆杠杆达到大力效果。双连杆纵向横向二维设置充分利用空间。本发明的优点:结构结实,力量大。
