Two hinge pins 113 are formed at a side of the front chassis 11 facing the rear chassis 12, two hinge slots 121 are formed at a side of the rear chassis 12 facing the front chassis 11 for corresponding to the two hinge pins 113, the two hinge pins 113 are inserted into the two hinge slots 121, respectively, and the front chassis 11 is hinge-coupled to the rear chassis 12 by being rotatably coupled in the hinge slots 121 through the hinge pins 113. Specifically, the hinge slot 121 is formed with a mounting shaft hole 122 penetrating the hinge slot 121, the hinge insert rod 113 is formed with a matching shaft hole 114 penetrating the hinge insert rod 113, the front end chassis 11 is rotatably connected to the rear end chassis 12 through the hinge shaft penetrating the mounting shaft hole 122 and the matching shaft hole 114, and thus the overall strength and rigidity of the front end chassis 11 and the rear end chassis 12 can be ensured through the hinge connection between the insert rod and the slot. Based on the structure, the ratio of the distance value between the two hinged slots 121 and the maximum width value of the rear chassis 12 is 4:10, so that the stress bearing uniformity of the whole chassis can be ensured, and the bearing strength is further improved.
As a specific embodiment, the articulation plunger 113 is formed with a defined ramp 115. The limiting slope 115 serves to guide the hinge pin 113 to be inserted into the hinge slot 121, and at the same time, the limiting slope 115 cooperates with a concave wall of the hinge slot 121, which refers to an outer wall of the hinge slot 121 formed, to be able to define a pre-installation position of the hinge pin 113.
