[0032] After the optical fiber listening device body 1 is installed inside the installation component 2 to protect its outside, the operation mechanism 4 drives the displacement component 5 to move along the connecting device 3, thereby indirectly providing a displacement driving force for the installation component 2. When it is installed at the bottom of the belt conveyor and used, after the optical fiber listening device body 1 is installed and protected by the installation component 2, it can drive the optical fiber listening device body 1 to move back and forth at the bottom of the belt conveyor in cooperation with the displacement component 5, so as to facilitate real-time listening detection of the whole, improve the abnormal listening detection efficiency, and facilitate timely maintenance of the belt conveyor.

When the upper mounting housing 201 is driven to displace, the second spring posts 802 cooperate with the rubber gaskets 801 to support on the optical fiber listening device body 1, providing a buffering effect between its installation gaps to prevent adverse effects caused by external stress during the movement process.
