[0023] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the connection structure 2 includes a connecting frame 201, a fixing bolt 202, a limiting plate 203, a mounting groove 204, a mounting bolt 205, a nut 206 and a mounting cap 207. The connecting frame 201 is arranged at the upper and lower ends of the connection between the first Bailey piece 1 and the second Bailey piece 3, the limiting plate 203 is arranged at the bottom end inside the connecting frame 201, and the mounting groove 204 is opened inside the upper and lower ends of the connection between the first Bailey piece 1 and the second Bailey piece 3. The limiting plate 203 is inserted into the interior of the mounting groove 204, and a limiting connection is formed between the limiting plate 203 and the mounting groove 204. The fixing bolt 20 2 is provided at the upper and lower ends of the connection between the first Bailey piece 1 and the second Bailey piece 3. Both sides of the connecting frame 201 are sleeved on the outside of the fixing bolt 202. The outside of the fixing bolt 202 is provided with a nut 206. The inside of the connection between the first Bailey piece 1 and the second Bailey piece 3 is inserted with a mounting bolt 205. One end of the mounting bolt 205 is provided with a mounting cap 207. Two groups of fixing bolts 202 are provided. The two groups of fixing bolts 202 are symmetrically distributed on both sides of the connecting frame 201.
