[0034] Reference Figure 1 The limiting connecting rod group 3 includes a plurality of first connecting rods 31 and second connecting rods 32 that intersect in an X shape and are hinged to each other.

[0035] Specifically, one end of the first connecting rod 31 close to the sliding rail guide frame 1 and one end of the second connecting rod 32 close to the sliding rail guide frame 1 are respectively hinged to two adjacent groups of steel bar trough units 2, and one end of the first connecting rod 31 away from the sliding rail guide frame 1 and one end of the second connecting rod 32 away from the sliding rail guide frame 1 are respectively slidably hinged to two adjacent groups of steel bar trough units 2.

[0036] Further, see Figure 1 and Figure 3 In Example 1 of the present application, in order to facilitate construction personnel to adjust the spacing between multiple groups of steel bar trough units 2, a straight limiting groove 211 is opened through the steel bar trough unit 2 along the extension direction of the slide rail guide frame 1, and the extension direction of the limiting groove 211 is consistent with the length direction of the slide rod 21.

[0037] In the embodiment 1 of the present application, the end of the slide bar 21 close to the steel bar holder 22 is taken as the top, and the end of the slide bar 21 close to the steel bar holder 22 is taken as the bottom. Figure 1 and Figure 4 A first ring 4 is fixedly provided inside the limiting slide groove 211 on one side close to the slide rail guide frame 1 , and a second ring 5 is slidably provided inside the limiting slide groove 211 on one side away from the slide rail guide frame 1 .

[0038] The first ring 4 and the second ring 5 have the same specifications, and the axial directions of the first ring 4 and the second ring 5 are parallel to the opening direction of the steel bar groove positioning hole 231, and the axial directions of the first ring 4 and the second ring 5 are perpendicular to the sliding rod 21 and the sliding rail guide frame 1; the lower end of the first connecting rod 31 and the lower end of the second connecting rod 32 respectively located in the two adjacent groups of limiting connecting rod groups 3 are hinged to the corresponding steel bar groove unit 2 through the first ring 4, and the upper end of the first connecting rod 31 and the upper end of the second connecting rod 32 respectively located in the two adjacent groups of limiting connecting rod groups 3 are slidingly hinged to the corresponding steel bar groove unit 2 through the second ring 5.
