A first bevel tooth 15 is fixedly connected to the outer wall of the double-ended screw sleeve 11, and a second bevel tooth 16 is meshed with the outer edge of the first bevel tooth 15. A connecting rod 17 is fixedly connected between the two second bevel teeth 16, and the second bevel teeth 16 at both ends of the connecting rod 17 are rotated to make the connecting rod 17 rotate. The connecting rod 17 is meshed with the first bevel teeth 15 corresponding to each other, so as to control the distance between the two relatively arranged support plates 1, and can be flexibly adjusted according to the width of the deep foundation pit. Two symmetrical fixing frames 18 are rotatably connected to the outer wall of the connecting rod 17, and the fixing frames 18 are rotatably connected to the double-headed screw sleeve 11. With the use of the fixing frames 18, the connecting rod 17 can be stabilized to ensure that the two second bevel teeth 16 and the corresponding first bevel teeth 15 will not be separated. Two symmetrical docking grooves 21 are provided on the upper end surface of the support plate 1, and two symmetrical docking blocks 22 are fixedly connected to the lower end surface of the support plate 1. A locking hole 23 is provided on one side of the docking block 22, and the two docking grooves 21 on the upper end surface of the single support plate 1 can be connected with the lower end of the support plate 1 adjacent to the vertical plane. The two docking blocks 22 on the upper and lower surfaces are docked to achieve preliminary docking between the upper and lower support components. A fixing column 31 is provided above the fixing block 13. The fixing column 31 is fixedly connected to the support plate 1. A sliding groove 32 is provided in the fixing column 31. A guide rod 33 is slidably connected in the sliding groove 32. A locking column 34 is fixedly connected to one end of the guide rod 33.
