Description

Technical Field

[0001] The utility model relates to the technical field of sawing machine clamping mechanisms, in particular to a clamping mechanism for a sawing machine. Background Art

[0002] A sawing machine is a mechanical device used to cut metal, wood and other materials. It usually consists of a saw blade with teeth and a vertically or horizontally movable worktable. During the cutting process, the saw blade moves on the worktable and cuts the material through the saw teeth.

[0003] When a sawing machine is in use, a clamping mechanism is required to clamp and fix the workpiece. The current clamping mechanism of a sawing machine has a single clamping direction for the workpiece when in use, and can only clamp the workpiece in a vertical direction or a horizontal direction. When the saw blade cuts the workpiece, the workpiece is prone to shaking, which makes it difficult for the workpiece to stably accept the saw blade cutting. Therefore, we propose a clamping mechanism for a sawing machine. Utility Model Content
