Title:
POWER SAW
Document Type and Number:
WIPO Patent Application WO/2017/088106
Kind Code:
A1
Abstract:
A power saw, comprising a base body (200) and at least two chains (100) surrounding the edge of the base body (200). Cutting blades (130) for cutting are provided on the chains (100). The at least two chains (100) are arranged on the edge of the base body (200) side by side. The two chains (100) are disposed around the edge of the base body (200) and arranged side by side. When the power saw runs, the two chains (100) simultaneously move and rotate in the same direction or opposite directions to implement cutting by means of the cutting blades (130) on the chains (100). When the power saw is used for cutting to make a wide cut, the cutting blades (130) on the two chains (100) perform cutting simultaneously, so that power is sufficient and sticking is avoided. Since the two chains (100) run independently, cutting can be completed without a large driving force. When cutting is performed to make a wide cut, cutting achieved by bidirectional motion of two chains (100) is easier than unidirectional cutting achieved by a single chain (100); moreover, the driving force is greatly reduced, materials are saved, and the costs are reduced.
