Saw with insert between handle and weld part at front end, has segment connected to insert by locking mechanism used to fix insert inside handle

摘要

A locking mechanism (40) is provided for connecting an insert segment (31) to the insert (30). The same mechanism is used to fix the insert inside the handle (10). The handle has a hole (11) in its top end for receiving the end of the weld part (20). An elastic coupling (50) in the bottom end of the handle is used to secure the handle to the sawblade (70). An adjustable angle elastic coupling (60) is provided in the bottom end of the weld part, enabling the sawblade to be held between these two couplings.
