Description

  The present invention relates to a case of a kind of anti-theft device, and in particular it can be assembled in a sealed state without the need for fixing with screws, and it is difficult to forcibly open it by an external force. The present invention relates to a design that can share the same case in either case of an anti-theft device that is used in the case of, for example, being suspended by an insertion method or being fixed to a wall.

The anti-theft device generates enormous voices to intimidate or announce illegal intrusions. In order to achieve this purpose, the most important thing is to accurately detect a fine motion and to have a function of preventing forced destruction by an external force. Existing anti-theft devices, regardless of detection type, are mostly combined with an internal substrate, an alarm device and an external combination case by means such as screws. The disadvantages of such a combination method are as follows.
1. Several people are arranged on one production line at the time of production, and each of them must share the screwing of the board, the alarm device and the external combination case, which is too much labor cost and combination cost.
2. The screw-type antitheft device needs to hide the position of the screw hole in actual use, otherwise the screw hole is exposed and easily opened and destroyed.
3. When all screw hole positions are provided at the bottom of the screw-type anti-theft device, it is inconvenient for battery replacement when fixed to the wall.
4). Most of the anti-theft devices that use a screw-type anti-theft mechanism are fixed to the handle of the hand-held article with the wire rope fixed to the main body, Instead of passing through the steering plate, it is easy to be removed by the thief.
