A second control switch 7 is installed above the mounting block 4 to control the circuit connection between the built-in battery and the lamp body 5. A limit block 23 is arranged outside the mounting block 4, and a third spring 24 is connected to the inner side of the limit block 23. The limit block 23 forms a front-to-rear telescopic structure with the mounting block 4 through the third spring 24. A mounting groove 25 is engaged with the outer side of the limit block 23, and the mounting groove 25 is opened on the inner wall of the accommodating groove 3. After being connected with the limit block 23, the mounting block 4 is fixed inside the accommodating groove 3. A horizontal hollow cavity 14 is arranged inside the mounting block 4, and a counterweight block 15 is arranged inside the hollow cavity 14. A left-right sliding structure is formed between the counterweight block 15 and the hollow cavity 14, and the counterweight block 15 and the hollow cavity 14 form a left-right sliding structure. A second spring 16 is connected to one side of the block 15 along the direction of vehicle travel to provide support for the counterweight block 15. After the vehicle stops urgently, the counterweight block 15 pushes the second spring 16 to move by inertia, and a trigger mechanism is arranged on the outer side of the counterweight block 15. After the counterweight block 15 moves, the limit block 23 can be controlled to move by the trigger mechanism, and the connection between the limit block 23 and the mounting groove 25 is released, so that the mounting block 4 automatically falls from the accommodating groove 3.

When the first magnetic block 17 moves to the relative position of the second magnetic block 21, the second magnetic block 21 can be attracted to move, and the magnetic attraction between the first magnetic block 17 and the second magnetic block 21 is greater than the elastic force of the third spring 24. The connecting block 22 is fixed on the inner side of the limit block 23 to control the movement of the limit block 23, and the limit block 23 is connected to the second magnetic block 21 through the connecting block 22. The limit block 23 can be automatically controlled to move by the attraction of the second magnetic block 21 to the first magnetic block 17;

[0037] During normal use, the mounting block 4 is embedded and installed in the receiving groove 3. The circuit connection of the spiral connecting wire 9 can be controlled by the first control switch 6, so that the lamp body 5 is powered by the movable plug connector 8.

The adjustment rod 20 is rotatably mounted on the left side of the adjustment plate 19, and the adjustment rod 20 penetrates the outer surface of the mounting block 4 and forms a threaded connection between the mounting block 4. The rotation of the adjustment rod 20 can drive the adjustment plate 19 to move, thereby adjusting the compression amount of the second spring 16 and adjusting the detection sensitivity of the counterweight block 15;

[0039] The elastic force of the second spring 16 can be adjusted according to the needs of use and the subsequent elastic force attenuation of the spring. When adjusting, the mounting block 4 is taken out from the accommodating groove 3, and then the adjusting rod 20 is controlled to rotate, so that the adjusting rod 20 drives the adjusting plate 19 to move through the threaded connection between the adjusting rod 20 and the mounting block 4, thereby changing the compression amount of the adjusting plate 19 on the second spring 16, and completing the adjustment of the buffering elastic force of the second spring 16; when the mounting block 4 is carried alone in the future, a distress signal can also be transmitted through the signal transmitter 10, which is convenient for rescue personnel to locate and search.

[0040] The limit block 23 is made of magnetic material, and an active control mechanism is arranged on the outer side of the limit block 23, and the active control mechanism is located inside the mounting groove 25 to control the movement of the limit block 23. The active control mechanism includes a third magnetic block 26, a manual control rod 27, a synchronous linkage frame 28 and a fourth spring 29. The third magnetic block 26 is arranged below the mounting groove 25, and the third magnetic block 26 and the limit block 23 are arranged with the same magnetic poles relative to each other, and the repulsive force between the third magnetic block 26 and the limit block 23 is greater than the elastic force of the third spring 24. The manual control rod 27 is fixed below the third magnetic block 26 to control the movement of the third magnetic block 26, and the lower end of the manual control rod 27 passes through the lower surface of the mounting block 4 and the mounting block 4 to form an up and down sliding structure. The synchronous linkage frame 28 is fixed above the third magnetic block 26 to make the two groups of third magnetic blocks 26 move synchronously. The fourth spring 29 is arranged on the outer side of the manual control rod 27 to provide a downward push reset force for the manual control rod 27.

[0041] In non-accidental circumstances, the mounting block 4 can also be manually taken out for use of the lamp body 5, and the manual control lever 27 is pressed to push the third magnetic block 26 to move upward. The two groups of third magnetic blocks 26 maintain synchronous movement through the synchronous linkage frame 28, and the third magnetic block 26 is pushed into the interior of the mounting groove 25 so that it is opposite to the limit block 23. At this time, the magnetic pole repulsion between the third magnetic block 26 and the limit block 23 will push the limit block 23 to move, release the connection between the limit block 23 and the mounting groove 25, and make the mounting block 4 fall from the accommodating groove 3. After subsequent use, the mounting block 4 is re-stuck and the limit block 23 is inserted into the mounting groove 25.
