The main body plate 1 has mounting screw holes 2 on its inner surface wall. A fixing block 9 is fixedly connected to the side of the main body plate 1. A limiting block 5 is fixedly connected to the side of the main body plate 1. A mounting frame 4 is slidably connected to the outer surface wall of the limiting block 5. A shock-absorbing frame 3 is fixedly connected to the outer surface wall of the mounting frame 4. A shock-absorbing rod 10 is fixedly connected to the inner surface wall of the shock-absorbing frame 3. The shock-absorbing rod 10 is slidably connected to the inner surface wall of the fixing block 9. A buffer spring 11 is fixedly connected to the shock-absorbing frame 3 through the fixing block 9. During operation, the main body plate 1 can be fixed to the wall using the mounting screw holes 2. The limiting block 5 can limit the sliding of the mounting frame 4.

Simultaneously, the return spring 14 is compressed synchronously until the locking block 15 moves to the side of the mounting groove 8. At this time, the return spring 14 pushes the locking block 15 into the mounting groove 8 and engages it.

Meanwhile, the buffer spring 11 can buffer the vibration, thereby reducing the impact of the mounting bracket 4 on the main control body 7. The limiting body 6 and the main control body 7 can be inserted into the mounting bracket 4. At the same time, the inclined side of the locking block 15 can assist the locking block 15 to slide into the limiting body 6, thereby allowing the locking block 15 to slide on the outer wall of the limiting rod 13.
