Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The sand blasting protection device for repairing the saw blade is shown in the combined drawings 1-4 and comprises two protection covers 2, namely a first protection cover 28 and a second protection cover 29, wherein the two protection covers 2 are respectively and sequentially buckled on two sides of the saw blade 1 and used for protecting the saw blade body 11 and the saw blade gap 15 so that only the end faces of the saw teeth 12 and the alloy tool bit 13 are exposed. The two protective covers 2 have the same structure and are in locking connection through the connecting component 3.
The shield 2 includes a circular guard plate 21, an annular guard plate 22, a connecting rod 25, an insert strip 23, and a through hole 27.
