The inner part of the inner groove 501 is fixed with a reset mechanism 7, the reset mechanism 7 comprises a sliding groove 701, the sliding groove 701 and the fixed plate 601 are integrally connected through a slot, two sides of the inner upper end of the inner groove 501 are connected with a first power supply reed 702, the inner lower end of the inner groove 501 is provided with a second power supply reed 703, two sides of the sliding frame 602 are fixed with a conductive reed 704, the upper end and the lower end of one side of the conductive reed 704 away from the central line of the inner groove 501 are provided with a second spring 705, the second spring 705 is adhered with the inner wall of the inner groove 501, the conductive reed 704 forms an elastic telescopic structure with the inner groove 501 through the second spring 705, the conductive reed 704 forms a sliding structure with the sliding groove 701 through the sliding frame 602, the upper end and the lower end of the conductive reed 704 are respectively movably connected with the first power supply reed 702 and the second power supply reed 703, because the conductive reeds 704 on two sides are connected with the second spring 705, when the sliding rack 602 is slid to a certain side by the touch of the first cloth belt 502 or the second cloth belt 505, the second spring 705 on a certain side generates a resilient force after being pressed, and the sliding rack 602 can be automatically pushed back to the original position, so that the protection device can continue to work.

The working principle is as follows: for the protective device for road and bridge construction convenient to use, firstly, a storage battery is placed in a power box at one side of a support rod 2, the positive pole and the negative pole of the power are respectively connected with a first power supply reed 702 and a second power supply reed 703, the first support rod 2 is placed on the ground, then the second support rod 2 is placed on the ground, a first cloth belt 502 and a second cloth belt 505 in the two support rods 2 are respectively pulled out in an opposite mode, male buckles 503 and female buckles 504 at the opposite ends of the first cloth belt 502 and the second cloth belt 505 are connected together, then, a second cloth belt 505 in the third support rod 2 is pulled out and is butted with the first cloth belt 502 in the second support rod 2, and splicing is sequentially carried out, so that the protective device is formed, the first cloth belt 502 and the second cloth belt 505 can block outside personnel instead of the traditional form of blocking by adopting iron railings, and the first cloth belt 502 and the second cloth belt 505 are soft, and because the female button 504 and the male button 503 can be separated, the first cloth belt 502 and the second cloth belt 505 can be separated, when the protection device is folded, each section of the support rod 2 can be independently folded and unfolded, instead of the folding and unfolding form of the protection device in the past, the protection device is labor-saving and convenient to fold and place, because when the first cloth belt 502 and the second cloth belt 505 are pulled out, the round tube 604 is pulled along the rotating shaft 603 by the pulling force, the round tube 604 generates the pulling force to the first spring 605, and the first spring 605 generates the resilience force to the round tube 604, the round tube 604 can respectively generate the reverse pulling force to the first cloth belt 502 and the second cloth belt 505, so that the first cloth belt 502 and the second cloth belt 505 can keep the tight state, when an outside person touches the first cloth belt 502 or the second cloth belt 505, the sliding frame 602 is driven by the force of the first cloth belt 502 or the second cloth belt 505 to slide along the direction of the sliding groove 701, and the conductive reed 704 on one side of the sliding frame 602 contacts with the first power supply reed 702 and the second power supply reed 703 respectively, a passage is formed inside, the power supply part starts to provide power for the loudspeaker 4 and other elements, and the loudspeaker 4 starts to perform voice broadcast after being electrified so as to remind external personnel, thus completing the use process of the whole road and bridge construction protective device convenient to use.
