[0016] 1. The square tube milling tooling of the fitness equipment is equipped with two placement pieces and a connecting shaft. When the staff fixes the two ends of the square tube between the two placement pieces, a driving motor is set to drive one of the placement pieces to rotate. At this time, due to the effect of the square tube, the two placement pieces can rotate at the same time. At the same time, since there is no shielding structure between the two placement pieces, it is convenient to perform milling processing on the surface of the square tube, thereby improving the practicality of the device.

[0017] 2. The square tube milling tooling of the fitness equipment drives the threaded rod to rotate by turning the rotating handle, and then drives the clamping plate to move downward by the threaded rod, so as to clamp and fix one end of the square tube, thereby improving the stability of the square tube. This solves the problem that when the staff fixes the workpiece inside the outer frame and needs to process the side of the workpiece, the outer frame will block the workpiece when the outer frame rotates, which makes it inconvenient to process the workpiece and affects the practicability of the device.
