The top of the first connecting rod 11 is fixed with a conical fixing block 14, and the side of the second bridge 2 is fixed with a second connecting block 15. A third sliding hole 16 is provided inside the second connecting block 15. The first bridge 1 and the second bridge 2 to be assembled are butted end to end. The first connecting rod 11 drives the conical fixing block 14 to enter the third sliding hole 16. A fourth sliding hole 17 is provided on the side of the second connecting block 15. A limit block 18 is fixed inside the fourth sliding hole 17. A second connecting rod 20 is slidably sleeved in the limit block 18. A third spring 21 is sleeved on the second connecting rod 20. One end of the second connecting rod 20 is fixed. There is a fixed block 19, and a wedge-shaped stop pin 22 is fixed at the other end of the second connecting rod 20. The stop pin 22 is slidably sleeved in the fourth sliding hole 17. The third spring 21 is located between the limit block 18 and the stop pin 22. The conical fixed block 14 squeezes the stop pin 22, and the stop pin 22 is pressed into the fourth sliding hole 17. After entering the third sliding hole 16, the stop pin 22 extends under the action of the third spring 21, and the conical fixed block 14 is clamped in the third sliding hole 16, completing the rapid docking of the two sections of the bridge.

[0021] Reference Figure 3 The stop pin 22 passes through the fourth sliding hole 17 and extends into the third sliding hole 16. The conical fixing block 14 is clamped in the third sliding hole 16 through the stop pin 22. When the two sections of the bridge need to be separated, the three groups of shift rods 9 can be pushed out of the card slot of the second sliding hole 10.
