[0031] The support mechanism 3 comprises a first support rod 30, the top of the first support rod 30 is rotatably connected to the middle part of the back surface of the protective plate 1, the inner side of the first support rod 30 is sleeved with a second support rod 31, the lower part of the back surface of the first support rod 30 is threadedly connected with a hand wheel 301, the upper part of the back surface of the second support rod 31 is provided with two linearly distributed threaded grooves 311, and the front side of the hand wheel 301 is threadedly connected to the inner side of the threaded groove 311.

[0032] When the construction is in progress, the periphery of the foundation pit needs to be protected to avoid irrelevant personnel from falling into the foundation pit. First, the protective plate 1 is placed at the edge of the foundation pit with the front face of the protective plate 1 facing the outside of the foundation pit. Then, the protective plate 1 is pulled to make the plurality of protective plates 1 be arranged in sequence. The movement of the protective plate 1 drives the inner connecting rod 20 to rotate around the connecting block 21, and the bottom of the connecting rod 20 slides in the sliding groove 10, so that the connecting rod 20 rotates and inclines. The inclination of the connecting rod 20 cooperates with the movement of the protective plate 1 to expand the protection range of the device. At this time, the first supporting rod 30 and the second supporting rod 31 are rotated to be inclined and then unfolded from the back side of the protective plate 1. Then, the hand wheel 301 is removed from the threaded groove 311, the second supporting rod 31 is pulled, the bottom of the second supporting rod 31 contacts the ground, the hand wheel 301 is fixed to the threaded groove 311 at the top, and the second supporting rod 31 is fixed to the first supporting rod 30. At this time, the second supporting rod 31 and the first supporting rod 30 can support and fix the back side of the protective plate 1 to support the entire device.

[0033] As shown in Figure 7 , the second supporting rod 31 is fixedly connected with a pedal 312 near the lower position on the back side, and the bottom of the second supporting rod 31 is fixedly connected with a bolt 313.

[0034] When the second supporting rod 31 and the first supporting rod 30 support and fix the protective plate 1, the pedal 312 can be stepped on. The pedal 312 drives the second supporting rod 31 to move downward after being stressed. The descent of the second supporting rod 31 drives the bolt 313 to descend. The bolt 313 is inserted into the soil layer after descending to fix the second supporting rod 31 and the first supporting rod 30.

[0035] As shown in Figure 7 , the bottom of the back side of the protective plate 1 is rotatably connected with a fixing rod 32 near the left and right sides, and the bottom of the fixing rod 32 is rotatably connected to the inner side of the second supporting rod 31.

[0036] When the second supporting rod 31 slides in the first supporting rod 30, the fixing rod 32 is stretched and contracted by rotating to cooperate with the second supporting rod 31. After the second supporting rod 31 is fixed in the first supporting rod 30 by the hand wheel 301, the fixing rod 32 supports and fixes the second supporting rod 31, so that the fixing rod 32, the first supporting rod 30, the second supporting rod 31 and the protective plate 1 form a triangular structure, thereby effectively improving the stability of the entire device.

[0037] As shown in Figure 1 and Figure 2 , the upper surface of the protective plate 1 is fixedly connected with a handle 11, and the front face of the protective plate 1 is fixedly connected with a linearly distributed reflective strip 12.

[0038] The handle 11 at the top of the protective plate 1 can facilitate the workers to take, and the reflective strip 12 can reflect part of the light back after being irradiated by the light, thereby improving the visibility of the protective plate 1 at night.

[0039] As shown in Figure 5 and Figure 6 , the bottom of the inside of the protective plate 1 is movably connected with the fixed plate 4, the bottom of the fixed plate 4 near the left and right sides is fixedly connected with the connecting block 40, the bottom of the connecting block 40 is fixedly connected with the clamping block 41, the inside of the top of the protective plate 1 near the right side is provided with the clamping groove 13, and the outer surface of the clamping block 41 is overlapped on the inside of the clamping groove 13.

[0040] When it is needed to unfold the protective plate 1 and the protection mechanism 2, the fixed plate 4 is first pressed, so that the fixed plate 4 drives the connecting block 40 at the bottom to descend, the connecting block 40 drives the clamping block 41 to descend, and the clamping block 41 moves to below the clamping groove 13, then the protective plate 1 is pulled, so that the clamping block 41 moves away from the clamping groove 13, and the protective plate 1 and the protection mechanism 2 can be unfolded.

[0041] As shown in Figure 5 and Figure 6 , the bottom of the fixed plate 4 and the clamping block 41 is fixedly connected with the spring 42, and the bottom of the spring 42 is overlapped on the inside of the protective plate 1.

[0042] When it is needed to connect the protective plate 1, the protective plate 1 is first pushed, so that the clamping block 41 at the upper left side of the fixed plate 4 is abutted on the outside of the clamping groove 13 and moves to the inside bottom of the clamping groove 13, then the fixed plate 4 and the clamping block 41 are driven by the spring 42 to ascend, so that the clamping block 41 is clamped into the inside top of the clamping groove 13, and the connection of the protective plate 1 is sequentially operated.

[0043] As shown in Figure 6 , the left side of the fixed plate 4 is fixedly connected with the limiting block 43, and the right side of the fixed plate 4 is provided with the limiting groove 44.

[0044] When it is needed to uniformly release the connection between the protective plates 1, since the fixed plates 4 are connected in combination when the protective plates 1 are connected, and the limiting block 43 at the left side of the fixed plate 4 is clamped into the limiting groove 44 at the right side of the fixed plate 4 when the fixed plate 4 is connected, the fixed plate 4 is pressed downward, so that the fixed plate 4 drives the fixed plates 4 at the left and right sides to descend through the limiting block 43 and the limiting groove 44, and the connection between the protective plates 1 is uniformly released when the multiple fixed plates 4 simultaneously descend.

[0045] The utility model discloses a working principle: when needing to protect the periphery of foundation pit, first, the front of protection board 1 is to the outside of foundation pit, then presses fixed plate 4, makes fixed plate 4 through limiting block 43 and limiting groove 44 drive multiple fixed plate 4 to drop simultaneously, and then the connection of multiple protection board 1 is removed, and the movement of protection board 1 drives connecting rod 20 to rotate and incline, and then makes connecting rod 20 cooperate with the movement of protection board 1, when needing to support and fix protection board 1, through rotating first support rod 30 and second support rod 31, protection board 1 is supported and fixed, and then the whole equipment is supported and fixed.
