[0031] Embodiment 3

[0032] like Figure 1 As shown, the utility model proposes a thermal break aluminum profile cutting sawing machine. Compared with the second embodiment, the detailed structure of the clamping assembly is recorded in this embodiment. The clamping assembly includes a fixed frame 24, a second telescopic device 25 and a fixed block 26.

The second elastic member 20 rebounds and drives the limit rod 17 to move downward and insert into the limit hole on the support frame 3 and the angle ruler 22 to limit the movement of the rotating disk 14 to prevent accidental touch.
