Fixing lantern ring used for being fixed to flexible track

The utility model relates to the technical field of robot flexible rails, in particular to a fixing lantern ring used for being fixed to a flexible rail. The self-locking structure can be conveniently and fixedly connected with the flexible track, the locking section is separated from the first bent section by twisting the locking section in the locking state, and the fixing lantern ring can be conveniently detached from the flexible track or the fixing position of the fixing lantern ring and the flexible track can be conveniently adjusted. In some embodiments of the invention, the fixed lantern ring is fixedly connected with the flexible track, so that the label fixing structure is prevented from being driven by the inspection robot. Under the condition that the fixed lantern ring is fixedly connected with the flexible track, the vibration reduction piece is connected between the fixed lantern ring and the vertical piece, vibration of the vertical piece can be reduced, and a label on the vertical piece is wi
