The support frame 1 is provided with a stop block 11. The stop block 11 can be fixed to the support 1. The stop block 11 is used for abutting against the second supporting foot 10 when the first mounting plate 7 is reset to the initial position.
Preferably, the second supporting leg 10 and the stopper 11 may be provided with magnets, so that the two can be further fixed by attraction of the magnets.
To facilitate the installation of the light receiver 52, preferably, as shown in fig. 1 and 2, the conveyor belt safe operation detection system may further include a second installation plate 12. The aforementioned light receiver 52 is provided on the second mounting plate 12.
