[0037] With reference to Figures 3 to 5The inside of the sliding plate 42 is slidably connected with two reset components 43, which provide the reset force for the sliding plate 42. Each of the two reset components 43 includes a positioning rod 4301, and the outer parts of the two positioning rods 4301 are fixedly connected to the inside left and right ends of the trapezoidal plate 41 respectively by welding process, thereby providing support for the two positioning rods 4301. The outer parts of the two positioning rods 4301 are slidably connected to the inside left and right ends of the sliding plate 42 respectively, so that the sliding plate 42 can smoothly slide along the positioning rods 4301. The outer parts of the positioning rods 4301 are sleeved with springs 4302, which are uniformly stressed by being limited. The bottom ends of the two springs 4302 are fixedly connected to the top left and right ends of the sliding plate 42 respectively, and the bottom ends of the springs 4302 are fixedly connected to the top of the sliding plate 42. The sliding plate 42 will squeeze the springs 4302 in the sliding process, so that the springs 4302 can store elastic potential energy, thereby giving the sliding plate 42 a reverse force for resetting;

The top side of each fixed plate 61 is fixedly connected with a transmission block 63, which is driven to slide synchronously by the fixed plate 61. The outer sides of the two transmission blocks 63 are respectively slidably connected to the inside of the left and right ends of the laying plate 1, and the two transmission blocks 63 can stably slide through the limitation of the laying plate 1. The proximal side of each transmission block 63 is slidably connected with a rhombic plate 64, which slides against the rhombic plate 64 in the process of sliding of the transmission block 63, so that the two rhombic plates 64 can slide to the proximal side;

[0040] The inside of the rhombic plate 64 is fixedly connected with a guide plate 65, which provides guidance for the sliding of the rhombic plate 64. The left and right ends of the laying plate 1 are each provided with a guide opening 66, the inside of which is slidably connected to the outside of the guide plate 65, and the guide opening 66 and the guide plate 65 slide together to provide guidance for the sliding of the guide plate 65.

The bottom side of each fixed plate 61 is fixedly connected with a spring 68, which can store elastic potential energy when the fixed plate 61 slides, and then gives the fixed plate 61 a force in the opposite direction to reset. The bottom ends of the two springs 68 are respectively fixedly connected to the inner walls of the left and right ends of the laying plate 1, and the springs 68 can be uniformly stressed by being fixed.

[0041] Working principle: when the device is needed, the laying plate 1 and the reinforcing plate 4 are placed against the road on both sides, then inserted into the deep soil, at the same time, the sliding plate 42 is pushed to slide downward, and the two spring one 4302 are stretched, so that the two spring one 4302 can store elastic potential energy, then give the sliding plate 42 a reverse force to reset, and in the process of sliding the sliding plate 42, the transmission plate 44 is driven to slide, so as to push the bottom plate 45 to slide downward, and drive the two opening plates 46 to slide, so as to pull the two extension plates 49 to rotate, and under the limitation of the rotating plate 47, the extension plate 49 can rotate to the inside of the trapezoidal plate 41, until the trapezoidal plate 4 is completely inserted into the deep soil, then the pushing force of the sliding plate 42 is released, at this time, the two spring one 4302 reset and transmit the resetting force to the bottom plate 45 to drive the two opening plates 46 to slide, so as to push the extension plate 49 to rotate, and under the limitation of the positioning shaft 48 and the rotating plate 47, the extension plate 49 can rotate and extend to both sides, and be inverted in the deep soil, so as to improve the stability.

[0042] Then, according to the required height of laying, the two vertical plates 67 on the extension plate 5 are guided into the inside of the laying plate 1, and the strip plate 62 is pulled to slide downward, so as to drive the two fixed plates 61 to slide and press the spring two 68, so that the spring two 68 can store elastic potential energy, then give the fixed plate 61 a reverse force to reset, and in the process of sliding the fixed plate 61, the transmission block 63 is also driven to slide, so that the transmission block 63 no longer abuts against the diamond plate 64, at this time, the vertical plate 67 abuts against the diamond plate 64 in the process of guiding sliding, so that the two diamond plates 64 slide to the far side, when the vertical plate 67 completes the sliding to the inside of the laying plate 1, the pulling force on the strip plate 62 is released, at this time, the spring two 68 resets to push the transmission block 63 to reset, so as to push the two diamond plates 64 to slide to the near side, and open and close in the inside of the two vertical plates 67 respectively, so that the laying plate 1 can form a whole with the extension plate 5, and then improve the application range.
