This design uses the pin shaft 3 to rotatably connect the traction longitudinal beam 1 and the semi-suspension beam traction shaft 4, and then the through shaft 43 of the semi-suspension beam traction shaft 4 penetrates the semi-suspension cross beam 5, and limits one side of the semi-suspension cross beam 5 under the action of the shoulder stop pad 42, thereby accelerating the installation speed, and then connecting the mounting nut 7 with the external thread 44, thereby limiting the other side of the semi-suspension cross beam 5 to prevent the semi-suspension cross beam 5 from being separated from the through shaft 43, thereby facilitating installation and simplifying the installation operation.

Similarly, the reinforcing plate 11 is used to reinforce the side wall of the semi-suspension beam 5 to avoid deformation caused by collision between the shoulder stop pad 42 and the mounting nut 7 and the semi-suspension beam 5 during rotation, thereby enhancing the anti-deformation effect. A gap is arranged between the shoulder stop pad 42 and the mounting nut 7 and the reinforcing plate 11, so as not to affect the rotation of the through-shaft 43 inside the semi-suspension beam 5.
