[0026] like Figure 2 As shown, guide rods 13 are fixedly connected inside the second sliding seat 5 and the fixed seat 8; the guide rods 13 are arranged in parallel with the first driving screw 6 and the second driving screw 9; the first fixed plate 7 and the second fixed plate 10 are respectively slidably connected to the guide rods 13; during operation, when the first fixed plate 7 slides inside the second sliding seat 5, and when the second fixed plate 10 slides inside the fixed seat 8, the sliding of the first fixed plate 7 and the second fixed plate 10 is restricted by setting the guide rods 13, so that the first fixed plate 7 and the second fixed plate 10 are less likely to tilt when sliding, and the sliding of the first fixed plate 7 and the second fixed plate 10 is more stable.

[0027] like Figure 2 As shown, a positioning block 14 is fixedly connected to the second threaded rod 4; the positioning block 14 is rotatably connected to the internal position of the first sliding seat 2; during operation, when the second threaded rod 4 rotates inside the first sliding seat 2, by arranging the positioning block 14 on the first sliding seat 2 and limiting the rotation of the positioning block 14 by the first sliding seat 2, the second threaded rod 4 can be made more stable when rotating.

[0030] When the support column is fixed by the first fixing plate 7 and the truss is fixed by the second fixing plate 10, by arranging a slidable sliding block 11 inside the first fixing plate 7 and the second fixing plate 10, the contact area between the first fixing plate 7 and the support column and between the second fixing plate 10 and the truss can be made larger, so that the sliding block 11 can better adapt to the shape of the support column and the truss, thereby making the first fixing plate 7 and the second fixing plate 10 more stable when fixing the support column and the truss.

[0031] When the support column and the truss are pushed and fixed by the sliding block 11, by setting an anti-slip pad 12 on the side wall of the sliding block 11, the contact area between the sliding block 11 and the support column and the truss can be made larger, so that the sliding block 11 has a better fixing effect on the support column and the truss.

[0032] When the first fixed plate 7 slides inside the second sliding seat 5, and the second fixed plate 10 slides inside the fixed seat 8, the sliding of the first fixed plate 7 and the second fixed plate 10 is restricted by setting the guide rod 13, so that the first fixed plate 7 and the second fixed plate 10 are less likely to tilt when sliding, and the sliding of the first fixed plate 7 and the second fixed plate 10 is more stable.

[0033] When the second threaded rod 4 rotates inside the first sliding seat 2, by providing a positioning block 14 on the first sliding seat 2 and limiting the rotation of the positioning block 14 by the first sliding seat 2, the second threaded rod 4 can be made more stable during rotation.

[0034] When the positioning block 14 rotates inside the first sliding seat 2, by arranging the anti-wear ball 15 between the first sliding seat 2 and the positioning block 14, the sliding friction between the first sliding seat 2 and the positioning block 14 can be changed into rolling friction, so that the friction force between the first sliding seat 2 and the positioning block 14 is smaller, thereby reducing the wear between the first sliding seat 2 and the positioning block 14.
