[0006] As a further description of the above technical solution:

[0007] The bottom surface of the fixed box is provided with wheels.

[0008] As a further description of the above technical solution:

[0009] The worm is meshingly connected to a worm wheel.

[0010] As a further description of the above technical solution:

[0011] The fixing plates are arranged in two groups in parallel.

[0012] As a further description of the above technical solution:

[0013] The top surface of the connecting plate is fixedly connected with a second fixing seat, and the top surface of the second fixing seat is fixedly connected with an alarm device body.

[0014] As a further description of the above technical solution:

[0015] The sliding rods and sleeve rods are provided in four groups.

[0016] The utility model has the following beneficial effects: in the utility model, the motor is started, the motor drives the worm to rotate, and the relative worm is synchronously driven through the transmission rod, so that the worm wheel meshing on the worm rotates, and the threaded rod threadedly connected in the worm wheel drives the worm wheel to extend and retract in the transmission rod, effectively driving the connecting plate to rise and fall, and when the connecting plate is raised and lowered, the alarm device body on the fixed seat 2 is driven, and is effectively stored in the fixed box, so the alarm device body is effectively preserved to prevent damage to the alarm device body.
