Sawtooth-replaceable swing saw blade

Abstract

The invention discloses a sawtooth-replaceable swing saw blade. The sawtooth-replaceable swing saw blade comprises a saw blade handle, a saw blade and a plurality of locking bolts, wherein a datum hole is formed in one end of the saw blade handle; an open slot is formed in the upper end of the datum hole; the open slot is communicated with the datum hole; the saw blade is arranged at the other endof the saw blade handle; the saw blade is detachably connected with the saw blade handle through the plurality of locking bolts; a plurality of sawteeth are uniformly arranged on the saw blade; the sawteeth are arranged at one end, far away from a junction of the saw blade and the saw blade handle, of the saw blade. Through arrangement of the saw blade handle and the saw blade into split structures, the saw blade handle and the saw blade are combined through the locking bolts, and when the sawteeth of the saw blade are damaged, the saw blade can be replaced with a new saw blade only by loosening the locking bolts for detaching the saw blade and the whole swing saw blade is not required to be replaced, so that the loss, the cost and the resource waste are reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of saw blades, especially the technical field of oscillating saw blades. 【Background technique】 [0002] The oscillating saw is a kind of power tool with a wide range of uses. It is small in size and can be used in many workplaces, such as industry, medical treatment, home improvement and other fields. Its working principle is that the output shaft swings around the axis line. Therefore, when the user After installing different working heads on the output shaft, a variety of different operating functions can be realized. Common working heads include saw blades, abrasive discs, scrapers, etc., which can realize work requirements such as sawing, cutting, grinding, and scraping. Swing saws Saw blades mainly rely on the sawtooth to cut materials, the loss of the sawtooth is large, and the loss of the saw handle is small. Generally, the sawtooth of the saw blade is broken but the saw handle can still be used. H...

Common working heads include saw blades, abrasive discs, scrapers, etc., which can realize work requirements such as sawing, cutting, grinding, and scraping. Swing saws Saw blades mainly rely on the sawtooth to cut the material, the loss of the sawtooth is large, and the loss of the saw handle is small. Generally, the sawtooth of the saw blade is broken but the saw handle can still be used. However, most of the existing saw blades are integrated, and the sawtooth is damaged. It is necessary to replace the entire saw blade, which is easy to cause waste of resources
