[0020] like Figure 1 and Figure 3 As shown, the adjustment mechanism 8 includes a rotating frame 81, an adjusting rod 82, a moving ring 83 and a screw rod 84. The left and right sides of the top plate 5 are rotatably connected to the rotating frames 81. The rotating frames 81 are provided with protective nets to facilitate shielding the top of the tunnel. The lower side of the rotating frame 81 is rotatably connected to the adjusting rod 82. The moving ring 83 is rotatably connected between the adjusting rods 82. The lower side of the middle part of the top plate 5 is rotatably connected to the screw rod 84. A handle is provided on the lower side of the screw rod 84 to facilitate rotation and adjustment. The moving ring 83 is threadedly connected to the screw rod 84.

[0021] When using the utility model, first move the bottom plate 1 into the tunnel through the moving wheels 7, and then support the bottom plate 1 through the supporting feet 6, then remove the latch 4, and adjust the position of the extension rod 3 on the vertical rod 2 according to the height of the tunnel. After the adjustment is completed, fix the extension rod 3 through the latch 4 so that the top plate 5 contacts the top of the tunnel, and then according to the width of the top of the tunnel, rotate the screw rod 84 to move the moving ring 83, push the adjusting rod 82 to rotate, and make the rotating frame 81 rotate to match the width of the top of the tunnel, thereby playing a role in shielding and protecting the top of the tunnel and preventing rocks from falling and injuring workers.
