The second insert rod 20 is inserted into the second slot, and the sliding limiting plate 11 limits the limiting rod 21. This makes it easy to install the protective plate 2 on the conveyor belt 1 without using professional tools to rotate the bolts. The installation is relatively convenient. By setting the protective plate 2, it is possible to prevent falling rocks in the mine from falling on the conveyor belt 1 and causing damage to the conveyor belt 1.

[0030] In this embodiment, as Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a rotating block 24 is installed on the limiting rod 21, and a rotating groove is opened on the second connecting rod 4 to cooperate with the rotating block 24. The rotating block 24 has multiple rotating cavities, and ball bearings 25 are rotatably installed inside the rotating cavities. A second engaging mechanism is provided on the limiting rod 21. By setting the rotating block 24 to be rotatably connected to the rotating groove, the limiting rod 21 can be rotated into the interior of the second connecting rod 4 for storage when not in use, reducing the space occupied by the limiting rod 21, and making it easy to rotate the limiting rod 21 out of the second connecting rod 4 and insert it into the first connecting rod 4.
