The specific working process is as follows: when the LED lamp designed by the invention is used, in a normal state, the two limiting notches 10 formed on the two hinged swing shafts 11 for mounting the LED lamp group 2 are limited by the upper ends of the two limiting clamping rods 15, and the lower ends of the two limiting clamping rods 15 are supported by the two bulges 26 on the two U-shaped clamping plates 25, so that the upper end surfaces of the two limiting clamping rods 15 are tightly attached to the straight surfaces of the two limiting notches 10 formed on the two hinged swing shafts 11 for mounting the LED lamp group 2; the two hinged pendulum shafts 11 are limited in the rotating direction and cannot rotate, namely, the rotation of the LED is locked in a normal state; in a static state; can be used normally.

When the device is impacted or pushed to topple, the trigger strip 4 corresponding to the toppling side is pressed by the table top of the device placing table and swings upwards relative to the base 5.

The first embodiment is as follows: the touch spring 4 swings to drive the hinged shaft 14 mounted on the touch spring to rotate, the hinged shaft 14 drives the second chain wheel 33 mounted on the hinged shaft to rotate, the second chain wheel 33 rotates to drive the corresponding first chain wheel 30 to rotate through the chain 32, the first chain wheel 30 rotates to drive the mounting rotating shaft 45 to rotate, the mounting rotating shaft 45 rotates to drive the corresponding two gears 31 to rotate, the two gears 31 rotate to drive the rack 34 to slide, and the rack 34 slides to drive the U-shaped clamping plate 25 to slide; in the sliding process of the two U-shaped clamping plates 25, the protrusions 26 which are originally in contact fit with the lower ends of the two limiting clamping rods 15 can gradually separate from the two limiting clamping rods 15, and the two limiting clamping rods 15 slide downwards along the cambered surfaces on the two protrusions 26; in the process that the two limiting clamping rods 15 slide downwards, when the upper ends of the two limiting clamping rods 15 slide out of the rotating areas of the two hinged swing shafts 11, the two limiting clamping rods 15 lose the limitation on the swinging of the LED lamp group 2; the driving force of the two limiting clamping rods 15 sliding downwards is gravity and the rotating extrusion force of the LED lamp group 2 swinging; at this moment, the LED lamp rotates around the swinging shaft of the LED lamp group 2 on the two supports 3 under the action of the gravity of the weight plate 1, finally the weight plate 1 swings to the lower side, and the LED lamp group 2 swings to the upper side, so that the LED is prevented from contacting and colliding with the bottom surface in the dumping process, and the LED is prevented from being damaged.

Example two: the touch spring 4 swings to drive the hinged shaft 14 arranged on the touch spring to rotate, the hinged shaft 14 drives the crank 40 arranged on the hinged shaft to swing, the crank 40 swings to drive the connecting rod 41 connected with the crank to swing, and the connecting rod 41 swings to drive the U-shaped clamping plate 25 to slide through the pin shaft 42; in the sliding process of the two U-shaped clamping plates 25, the protrusions 26 which are originally in contact fit with the lower ends of the two limiting clamping rods 15 can gradually separate from the two limiting clamping rods 15, and the two limiting clamping rods 15 slide downwards along the cambered surfaces on the two protrusions 26; in the process that the two limiting clamping rods 15 slide downwards, when the upper ends of the two limiting clamping rods 15 slide out of the rotating areas of the two hinged swing shafts 11, the two limiting clamping rods 15 lose the limitation on the swinging of the LED lamp group 2; the driving force of the two limiting clamping rods 15 sliding downwards is gravity and the rotating extrusion force of the LED lamp group 2 swinging; at this moment, the LED lamp rotates around the swinging shaft of the LED lamp group 2 on the two supports 3 under the action of the gravity of the weight plate 1, finally the weight plate 1 swings to the lower side, and the LED lamp group 2 swings to the upper side, so that the LED is prevented from contacting and colliding with the bottom surface in the dumping process, and the LED is prevented from being damaged.
