[0034] In this embodiment, after the top plate 11 is tightly attached to the top surface of the tunnel, the fixing rod 155 can be removed. Under the influence of gravity, the telescopic leg 154 slides out of the support leg 151 and is supported on the bottom surface by the support foot 156. The fixing rod 155 can be inserted into the corresponding fixing hole 157 so that the support leg 151 can provide sufficient support. The four support legs 151 make the support effect of the device stronger. When the two top plates 11 move relative to each other, they will drive the two adjacent support legs 151 to move relative to each other, causing the two movable reinforcing rods 141 to deform around the reinforcing rod 142 as the axis, and causing the sleeve 144 to slide on the surface of the support leg 151.

When the turntable 25 is rotated, it drives the threaded rods 26 on the left and right sides to rotate. Since the two threaded rods 26 are in opposite directions, they can drive the two threaded sleeves 24 to move relative to each other, and drive the two support frames 21 to contract or expand. The top plate 11 fits the shape of the tunnel top surface and adheres to the tunnel top surface under the compression of the base mechanism 2 to provide support. The relative movement of the two top plates 11 will drive the two adjacent support legs 151 to move relative to each other, and drive the two movable reinforcing rods 141 to deform around the reinforcing rod 142 as the axis, and drive the sleeve 144 to slide on the surface of the support leg 151.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
