The sealing plate 21 and the sealing protrusion 22 have the effect of sealing and positioning multiple snap ring mounting blocks 10.

[0039] It should be noted that the present invention is an exhaust casing bracket for an aircraft engine. When in use, the snap ring mounting block 10 and the bracket body 1 are first in a separated state, and the mounting snap ring 16 and the snap ring mounting block 10 are also in a separated state. The shield body 23 is first sleeved on the outer side of the casing body 24, and then the snap ring mounting block 10 is inserted into the bracket body 1, and the connecting protrusion 13 is inserted into the connecting groove 7 to achieve the effect of sliding connection between the snap ring mounting block 10 and the bracket body 1. Then, the notched end of the mounting snap ring 16 is inserted into the main body mounting through-hole 8 in the bracket body 1 for rotation, so that the mounting snap ring 16 passes through the mounting block through-hole 15 in the snap ring mounting block 10 and rotates, and finally the mounting snap ring 16 passes through the shield body 23 and the connecting plug 25 on the outer side of the casing body 24.
