在一九七○年上半年,我工区四队木工班,在党支部的关怀和支持下,通过参观局技术革新展览会之后,在“吴元福四用刨光机”的启发下,自己动手,利用废旧材料,制成了一台木工多用锯。多用锯的构造是由锯身、电动、轴和多用工作台四部分组成。共原理是采用一轴多用,在平放时,主要用于开料, In the first half of 1970, the four teams of woodworking workshops in our work area, under the care and support of the Party Branch, visited the Bureau’s technological innovation exhibition and were inspired by the “Wu Yuanfu Four-purpose Planer”. Using waste materials, a woodworking multipurpose saw was made. The utility model is composed of a saw body, an electric motor, a shaft and a multi-purpose workbench. The common principle is to use one axis for multiple purposes, and when it is laid flat, it is mainly used to open materials.
