The chain arm saw combines the flexibility of the mechanical arm and the efficient cutting ability of the chain saw, making the operation more convenient and safe. It is a highly efficient stone processing machine. In order to facilitate cutting, the direction of the chain arm on the chain arm saw can be adjusted.

[0003] In the prior art, the mounting device of the chain arm of the chain arm saw includes a rotating component, a support frame arranged on the rotating component and a mounting frame slidably connected to the side wall of the support frame. The chain arm is fixed on the mounting frame, and the rotating component drives the mounting frame to rotate through the support frame, and the mounting frame drives the chain arm to rotate, so that the chain arm rotates along the vertical rotation axis and faces different directions while keeping itself vertical until it reaches the target direction.
