[0027] like Figures 1-6 As shown, the top-mounted bracket mechanism for a fall detector proposed in this utility model includes a mounting plate 1, expansion screws 5, a mounting cylinder 7, an anti-detachment mechanism, and an adjustment mechanism.

[0028] The top of the mounting plate 1 has a guide groove 2. There are two guide grooves 2 with a certain curvature. The cross-section of the guide groove 2 is an inverted "T" shape. There are two expansion screws 5, which correspond one-to-one with the guide grooves 2.

[0029] Expansion screw 5 is fixed to the ceiling, and a nut 6 is fixedly connected to the end of expansion screw 5. The nut 6 is adapted to the guide groove 2.

[0030] A fall detector 8 is fixedly connected to the bottom of the mounting cylinder 7, and the mounting cylinder 7 is rotatably connected to the mounting plate 1.

[0031] The anti-detachment mechanism is installed in the mounting plate 1, and one end of the anti-detachment mechanism extends into the guide groove 2 to limit the expansion screw 5.

[0032] The adjustment mechanism is set inside the mounting cylinder 7 and corresponds to the anti-detachment mechanism. One end of the adjustment mechanism is connected to the mounting cylinder 7, and the other end of the adjustment mechanism is connected to the anti-detachment mechanism for adjusting the anti-detachment mechanism.

[0033] Example 2
