Disassembling and assembling device for smoke fire detector

The utility model relates to the technical field of fire-fighting equipment dismounting tools, in particular to a dismounting device for a smoke-sensing fire detector, which comprises a support rod and a dismounting head, the dismounting head comprises a brake clamp at the upper end of the support rod and a brake handle at the lower end of the support rod, and the brake clamp and the brake handle are connected through a brake cable. When the detector body needs to be disassembled, the supporting rod is held by a hand to align the disassembling and assembling head with the detector body, the supporting rod is rotated to enable the detector body to rotate to the position where the detector body can be separated from the base, the clamping covers are fixedly installed at the two ends of the clamping part of the brake clamp, and the clamping covers are fixedly installed at the lower ends of the clamping covers. In the dismounting process, dust left after the base of the detector is used for a long time can fall i
