Description

A sawing machine that is easy to operate

Technical Field

The utility model belongs to the technical field of sawing machines, and in particular relates to a sawing machine that is easy to operate.

Background Art

A sawing machine is a machine used to cut various objects or materials. It is widely used in various fields such as industry, agriculture, construction, and woodworking. The development history of sawing machines can be traced back to ancient times. It was first used for stone processing, and later gradually used for cutting materials such as steel and wood. The sawing machine can not only perform simple cutting operations, but also can be adjusted and controlled according to different needs. There are manual sawing machines, semi-automatic sawing machines, and fully automatic sawing machines.

During use, the existing sawing machine fixes and clamps the workpiece relatively on one side of the saw blade. After clamping, the position of the workpiece cannot be adjusted. The position of the workpiece depends on the alignment before clamping. The one-sided clamping method makes it easy for the other end of the workpiece to fall or lift up during the sawing operation due to lack of holding force, which will lead to saw clamping and affect the smooth and stable progress of the operation.
