Detailed Description

Example (b):

an anti-theft alarm, as shown in figure 1, comprises a main machine 1, a fixing plate 2 fixed on a door plate and a supporting plate 3 used for supporting the main machine 1, wherein the main machine 1 is rectangular. The fixing plate 2 is provided with a counter bore 14 for a screw to pass through, and the fixing plate 2 is fixed on the door plate through the screw. The fixed plate 2 is fixed with a connecting plate 4 and a limiting plate 5 which are horizontally perpendicular to the fixed plate 2, the limiting plate 5 is positioned above the connecting plate 4, and the distance between the limiting plate 5 and the connecting plate 4 is greater than the length of the host 1.

As shown in fig. 1 and 2, two symmetrically arranged guide rods 6 are disposed at the bottom of the support plate 3, two guide holes 7 matched with the guide rods 6 are disposed on the connecting plate 4, and the guide holes 7 extend along the length direction of the fixing plate 2. The guide bar 6 is slidably coupled in the guide hole 7 and one side of the support plate 3 is disposed adjacent to the surface of the fixing plate 2.
