<p>#CMT# #/CMT# The circular saw has pair of walls (1') with a vertically oriented blade arranged in upright frame (7). A swiveling lever pivotally mounted on the end of a support of the upright frame is attached to connecting edge of walls. The connecting edge of walls is fixedly attached to ends of the support. A pair of parallelogram lever (5,5') is directed downwards to bottom-side support (6) or pivotally mounted to upright frame. #CMT#USE : #/CMT# Circular saw for cutting wood. #CMT#ADVANTAGE : #/CMT# Since the pair of parallelogram lever is directed downwards to bottom-side support, the overall length of the parallelogram lever is reached and the saw is raised only to a small distance. By attaching a spring to the circular saw, desired restoring force is provided so that operability and safety of the cutting saw are improved. The fatigue of the user is reduced and the structure of the circular saw is simplified. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the front and side views of the circular saw. 1' : Walls 5,5' : Parallelogram lever 6 : Bottom-side support 7 : Upright frame 12 : Extension portion.</p> |
