In order to achieve communication of the electrical circuit between the battery 13 and the buzzer 5, the alarm further comprises a triggering assembly. The trigger assembly comprises a fixed block 17 fixedly arranged in the control box 3, and a through hole 23 is formed in the fixed block 17. The top inner wall and the bottom inner wall of the through hole 23 are respectively provided with a yielding groove 24, and the interiors of the two yielding grooves 24 are respectively and slidably connected with a movable electrode 25. One of the movable electrodes 25 is electrically connected with the battery 13, and the other movable electrode 25 is electrically connected with the buzzer 5. The third springs 26 are fixedly arranged on the sides, away from each other, of the two movable electrodes 25, and the other ends of the two third springs 26 are fixedly connected with the inner wall of one side of the yielding groove 24. Under normal conditions, the two moving electrodes 25 are kept in a separated state due to the traction action of the third spring 26, thereby breaking the electric circuit between the battery 13 and the buzzer 5.
In order to complete the connection of the two sections of cables and simultaneously complete the connection of the triggering component and the cable current, the alarm further comprises a communication component. The communication assembly comprises a fixed pipe 18 fixedly embedded in the inner wall of the top of the upper half shell 2, and a moving block 19 is connected inside the fixed pipe 18 in a sliding manner. The bottom of the moving block 19 is provided with an electrode sheet, and the electrode sheet is electrically connected with the electromagnet 14. The bottom inner wall of the lower half shell 1 is fixedly provided with a threaded rod 10, and the threaded rod 10 is used for completing winding connection of two sections of cables and is made of conductive materials. One end of the threaded rod 10 is in sliding fit with the inner wall of the fixed tube 18 and with the electrode plate at the bottom of the moving block 19. When two lengths of cable are connected by threaded rod 10, they form a conductive path for energizing electromagnet 14.
To ensure that the connection electrode 16 is in a separated state from the two moving electrodes 25 in the energized condition, the trigger assembly further comprises a slider 15 slidably mounted inside the control box 3. A bump is fixedly arranged on one side of the sliding block 15 close to the fixed block 17, and the bump is matched with the through hole 23. The inside of the bump is fixedly embedded with a connecting electrode 16, and two ends of the connecting electrode 16 respectively penetrate through the top and the bottom of the bump and are matched with two movable electrodes 25. Two fixing rods 21 are fixedly arranged on one side of the sliding block 15, and one ends of the two fixing rods 21 penetrate through one side of the fixing block 17 and one side of the control box 3 in a sliding mode.

The two tension springs 22 are used for pulling the sliding block 15 to move, so that the protruding blocks are inserted into the through holes 23, and the connection electrodes 16 are tightly attached to the two movable electrodes 25. However, when the electromagnet 14 is energized, it attracts the sheet iron layer on one side of the slider 15, so that the slider 15 moves against the elastic force of the tension spring 22, and the connection electrode 16 is separated from the two moving electrodes 25.
Specifically, an electromagnet 14 is fixedly mounted on the inner wall of one side of the control box 3 far away from the tension spring 22, an iron sheet layer is arranged on one side of the sliding block 15, and the electromagnet 14 is magnetically connected with the sliding block 15 through the iron sheet layer. In this way, in the case where the cable is normally connected and energized, the electromagnet 14 attracts the slider 15, separating the connection electrode 16 from the two moving electrodes 25, thus breaking the circuit between the battery 13 and the buzzer 5. Once the cable is cut off or disconnected, the electromagnet 14 loses electricity, the sliding block 15 moves under the action of the tension spring 22, the connecting electrode 16 is tightly attached to the two movable electrodes 25, and therefore a circuit between the battery 13 and the buzzer 5 is connected, and the buzzer 5 gives out an audible alarm.
