[0044] The two sides of the transverse shear plate 330 respectively extend outwardly with horizontal bars, and the horizontal bars are fixedly connected with the transverse steel bars 301. In this way, the horizontal bars are connected to enhance the ability of the transverse steel bars 301 to resist longitudinal force and avoid damage or breakage of the transverse steel bars 301 by bending outwardly.

[0045] The first step 220 is concave downwardly, and a plurality of grooves 500 are arranged along the length direction of the first step 220, two rolling shafts 510 are arranged along the length direction of the grooves 500 and are fixed in the grooves 500, and the two rolling shafts 510 are respectively located on the two sides of the grooves 500; the grooves 500 are provided with an oscillating bar 520, the middle part of the oscillating bar 520 protrudes downwardly with an abutting block 521, and the abutting block 521 abuts downwardly on the middle part of the grooves 500.

The upper part of the roller 510 is movably arranged in the receiving groove 522. The second step 320 is a flat surface. When the second step 320 is pressed downward on the first step 220, the second step 320 is in abutment with the top surface 5201 of the swing bar 520. The swing bar 520 swings up and down around the abutment block 521 as the swing center to adjust the position. The swing bar 520 is pressed to bend downward until the second step 320 is in abutment with the first step 220.

[0048] Through the structure of the swing bar 520, when the second step 320 is pressed on the first step 220,

[0049] The second step 320 and the first step 220 have an alignment gap. The second step 320 is horizontally moved to realize alignment. After alignment, the second step 320 is fixed by the bolt 400. During the process of pressing the second step 320 downward, the swing bar 520 is pressed to bend downward. The swing bar 520 has elasticity. The both ends of the swing bar 520 are deformed to be flush with the surface of the first step 220. The swing bar 520 applies an opposite elastic restoring force to the second step 320, so that the connection between the connecting plate and the end plate 210 is more stable.

[0050] In addition, because of the alignment gap, the swing amplitudes of the both sides of the swing bar 520 are different. Because the roller 510 is embedded in the receiving groove 522, during the horizontal movement of the second step 320, the roller 510 rolls to push the first step 220 to move to align with the second step 320. The swing bar 520 has the function of automatic swing adjustment, so that the center of gravity of the second step 320 is aligned with the abutment block 521.

[0051] The above only describes the preferred embodiments of the present application and is not used to limit the present application.
