Description

Technical Field

[0001] The utility model relates to the technical field of saw chains, in particular to a stone saw chain. Background Art

[0002] It is known that a saw chain is a very convenient and powerful portable tool with the ability to replace the chain. However, the existing saw chain cutting heads for sawing stone and concrete can only be welded on two connecting pieces, which has very high welding requirements and expensive welding equipment. Therefore, there is also a stone saw chain disclosed in the Chinese utility model patent with authorization announcement number CN203449483U, which includes a plurality of evenly arranged anti-rebound middle guide teeth, and the top and bottom between two adjacent anti-rebound middle guide teeth are alternately provided with connecting pieces and bent connecting pieces, and the sides of the bent connecting pieces are fixed with cutting bits, and the anti-rebound middle guide teeth and the connecting pieces and bent connecting pieces alternately arranged on the upper and lower sides are connected to form a chain structure by rivets. This structure adopts a connecting piece and a bent connecting piece. The bent connecting piece is bent into two fixed plates at right angles to each other, which are a bottom plate and a cutter head fixing plate, respectively. The bottom plate is connected to the anti-rebound middle guide teeth by rivets, and the cutter head fixing plate fixes the cutting head through a clamping table. The edge of the cutting head in contact with the cutter head fixing plate is reinforced by welding, which not only ensures the strength of the cutting head but also improves the hardness of the connecting piece, and is convenient for maintenance and replacement of the cutter head. However, the cutting head is still not strong enough, and sometimes there is a collision of the cutting head. It is necessary to make improvements for this situation. Utility Model Content
