Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1-3, a smoke alarm comprises an alarm 1, an outer cylinder 2 and an inner cylinder 4, wherein the outer cylinder 2 is installed on one side surface of the alarm 1 close to a wall top, an insertion cavity is formed in the outer cylinder 2, an insertion opening which is communicated with the insertion cavity and used for the inner cylinder 4 to enter and exit is formed in the outer cylinder 2, and a connecting piece used for fixing the inner cylinder 4 is connected in the insertion cavity; the inner cylinder 4 is connected with a clamping piece positioned in the sliding groove 7; the sliding chute 7 is of a seven-shaped structure; the inner cylinder 4 is also connected with a lantern ring 6 for fixing.

In the specific embodiment, the connecting piece comprises a spring 3, one end of the spring 3 is arranged in the insertion cavity, and the other end of the spring 3 is connected with the inner cylinder 4.

In the specific embodiment, the clamping piece comprises a clamping column 5, the clamping column 5 is detachably arranged on the inner cylinder 4, and the clamping column 5 slides in the sliding groove 7.

The working principle and the using process of the utility model are as follows: this smoke detector alarm, during the use, only need rotate alarm 1 and make the card post 5 on the inner tube 4 take out from the seven font spout 7 on the urceolus 2, again because the spring is connected inner tube 4 and urceolus 2, make it have tensile properties, make things convenient for people direct tensile certain distance and maintain it.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed.
