The second connecting head 12 is connected by using a tool so that the second connecting head 12 can drive the corresponding first screw rod 13 to start rotating.

[0026] See also Figure 1 , Figure 2 The outer surface of each track plate (5) is provided with a slot (16), and the inner wall of each slot (16) is slidably connected to the corresponding push plate (4). When the push plate 4 slides horizontally along the fixing frame 1, it will be inserted into the corresponding slot 16 to fix the track plate 5.

[0027] See also Figure 1 , Figure 2 The outer surface of each first bolt 6 is threadedly connected to the fixing frame 1, and the inner wall of each track plate 5 is inserted with a second bolt 9.

The rotation of the first screw rod 13 can drive the corresponding push block 10 to move horizontally along the corresponding first screw rod 13, and at this time, the push block 10 can slide horizontally along the corresponding fixed groove 14.
