Then, when the limiting groove on one side of the adjusting plate is aligned with the first limiting column, the rebound force of the third spring will push the first limiting column into the interior of the limiting groove, so as to facilitate the limiting and fixing of the adjusting plate after it rotates, thereby facilitating the staff to replace the conveyor belt.
