DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment, Figure 1-4 A smoke alarm that is easy to install is provided. The utility model comprises a shell 1, two springs 2 are fixedly connected inside the shell 1, lower bases 3 are fixedly connected to the opposite sides of the two springs 2, trapezoidal blocks 4 are fixedly connected to the opposite sides of the two lower bases 3, extension rods 5 are fixedly connected to the back sides of the two lower bases 3, handles 6 are fixedly connected to the back sides of the two extension rods 5, a positioning rod 7 is slidably connected inside the shell 1, a clamping block 8 is fixedly connected to the outside of the positioning rod 7, a first magnetic block 9 is fixedly connected inside the shell 1, and a second magnetic block 10 is fixedly connected to the bottom of the positioning rod 7;

[0028] After the smoke is identified by the identifier 13, the warning light 17 is activated to warn;

[0029] The first magnetic block 9 and the second magnetic block 10 attract each other, and the top of the positioning rod 7 is fixedly connected to the upper base 11;

[0030] The positioning rod 7 can be fixed by the upper base 11;
