[0035] Reference Figure 1 , Figure 3 and Figure 6The connecting component includes a plug-in block 11, and a square groove 4 is provided at the side end of the plug-in block 11 so that the inclined surface block 12 can slide in to keep the main rod 1 and the auxiliary rod 9 relatively fixed. The outsides of multiple groups of plug-in blocks 11 are respectively slidably connected to the two ends of the main rod 1 and the right end of the auxiliary rod 9.

[0036] Working principle: Slide the U-shaped block 7 to the side end of the belt conveyor, and then rotate the threaded rod to allow the clamping block 8 to slide up as a whole so that the upper end of the clamping block 8 and the upper part of the U-shaped block 7 can clamp the entire device to the side end of the belt conveyor, and then slide up so that the connecting rods 3 at the upper ends of the auxiliary rods 9 at both ends can slide into the interior of the square groove 4 at the upper end of the main rod 1. At this time, the inclined surface block 12 is squeezed by the plug-in block 11 to slide into the main rod 1 or the auxiliary rod 9 to squeeze the spring 2 13. When the plug-in block 11 completely slides into the side end of the main rod 1 or the auxiliary rod 9, the spring 2 13 squeezes to allow the inclined surface block 12 to slide into the side end of the plug-in block 11, and then slide the connecting rod 3 down.

When the clamping roller 6 is not in contact with the belt, the bolt 14 can be turned to allow the slider 5 to drive the clamping roller 6 to fine-tune to the position in contact with the belt. At this time, the belt is clamped by the clamping roller 6 so that it can return to its original position when it is offset.
