Abstract

The invention discloses a novel telescopic saw frame. The novel telescopic saw frame comprises a front arm, a frame beam and a handle, wherein the frame beam consists of a front frame beam and a back frame beam; the front frame beam is connected with the front arm; the back frame beam is connected with the handle; a plurality of holes A with the same size are formed in the front frame beam; a plurality of holes B with the same size are formed in the back frame beam; the holes A are the same with the holes B in size; a pin is arranged in the connected place of the front frame beam and the back frame beam, and penetrates through the holes A and the holes B; and the saw frame becomes the telescopic saw frame through changing the position of the pin penetrating through the holes. As the frame beam is telescopic, and can be provided with saw blades with different lengths and sizes, the saw frame has the advantages of simple structure, convenience for use and economy.

Description

technical field [0001] The invention relates to a saw frame, in particular to a saw frame capable of installing saw blades of different lengths. Background technique [0002] In today's real life and production, the saw is a tool that we cannot avoid. Carpenters sawing wood, fitters sawing metal, are inseparable from saws. In our usual home work, a saw is also indispensable. Generally, a saw is composed of a saw blade and a saw frame. The saw frame seen on the market can only be equipped with a saw blade of a specific length, resulting in great waste. The application number is CN200330129099.8, which discloses a retractable saw frame. There are three clamping positions on the saw frame. When installing saw blades of different lengths, the clamping positions on the saw frame can be easily used. Only saw blades of three different lengths can be installed, and saw blades of other lengths cannot be used, causing inconvenience and waste. Contents of the invention [0003] The...
