One end of the first stepped column is sleeved with a torsion spring. The two ends of the rectangular strip are respectively provided with a second stepped column, and the thin end of the second stepped column is matched with an L-shaped block.

[0008] An installation cavity is formed between the L-shaped block and the T-shaped block, and the first installation column is arranged inside the installation cavity.

[0009] Preferably, the first stepped column is located between the T-shaped block and the second stepped column;

[0010] One end of the torsion spring abuts against one side of the T-shaped block, and the other end abuts against one side of the L-shaped block.

[0014] Preferably, a through hole is formed in the L-shaped block, and the L-shaped block is fitted on the second stepped post through the through hole.

[0015] The utility model has the following beneficial effects:

[0016] 1. In the utility model, the L-shaped block is extruded by the first mounting post, so that the L-shaped block rotates on the second stepped post, and the L-shaped block extrudes the torsion spring to generate elastic force, thereby increasing the distance between the L-shaped block and the T-shaped block.

The mounting plate 1 is a rectangular structure and is fixed to the wall by bolts. One side of the mounting plate 1 is provided with a square block 2, and the two sides of the square block 2 are respectively provided with a first mounting post 201 and a second mounting post 202. Both the first mounting post 201 and the second mounting post 202 are cylindrical structures.

[0025] On the rear side of the gas alarm body 3, there is a rectangular strip 4. One side of each end of the rectangular strip 4 is respectively provided with a T-shaped block 401. The two T-shaped blocks 401 are horizontally installed at both ends of the rectangular strip 4. Each end of the rectangular strip 4 is respectively provided with a first stepped post 402. A torsion spring 404 is sleeved on the thin end of the first stepped post 402. Each end of the rectangular strip 4 is respectively provided with a second stepped post 403. The thin end of the second stepped post 403 is fitted with an L-shaped block 405. One side of the bottom end of the L-shaped block 405 is a bevel structure, which is convenient for applying pressure to the L-shaped block. A through hole 406 is opened on the L-shaped block 405, and the L-shaped block 405 is fitted on the second stepped post 403 through the through hole 406.
