[0025] In this embodiment, the mounting plate 20 is connected to the first main plate 13 and the second main plate 14 via a slot structure, resulting in a tighter and more stable connection. It can be understood that the slot connection structure can be welded, riveted, glued, etc. The mounting plate 20, the first main plate 13, and the second main plate 14 can also be an integral structure, formed by partial bending of an overall steel structure.

[0026] Furthermore, the first main plate 13 and the second main plate 14 are respectively provided with buffer grooves 132 (142) on the lower edge of the corresponding first connecting groove 131 (141), and the buffer grooves 132 (142) form a hooking ear 133 (143) adjacent to the hooking side 11.

[0027] In this embodiment, a buffer groove 132 (142) and a hooking ear 133 (143) are provided on the lower side of the corresponding first connecting groove 131 (141). During the hooking process, for the rear trailer of the tractor with different R angles, the hooking ear 133 (143) can be compressed and move to the other side of the buffer groove 132 (142), so that the hooking angle 21 of the hooking plate 20 and the main body 10 can be fully hooked with the rear trailer of the tractor, so that the hooking structure is connected stably.

[0028] Furthermore, the first main plate 13 and the second main plate 14 respectively extend load connection portions 134 (144) outward from the upper side of the corresponding first connecting groove 131 (141), and the load connection portions 134 (144) are respectively connected to the upper side of the hanging plate 20.

[0029] In this embodiment, the first main plate 13 and the second main plate 14 extend on the upper side of the hanging plate 20 to form a load connection portion 134 (144), which increases the load support force on the upper side of the hanging plate 20 and is beneficial to improving the hanging load strength.

[0030] Furthermore, the side connection portion 11 is formed by the first main body plate 13 and the second main body plate 14 extending longitudinally below the corresponding first connecting groove 131 (141). In this embodiment, the side connection portion 11 is a longitudinal structure, and the longitudinal side connection portion 11 is adapted to the plate-like surface of the tractor's rear rack, so that the mounting structure fits more tightly and the connection is stable.

[0031] Furthermore, the lower part of the first main body plate 13 is provided with a second connecting groove 135, and the lower part of the second main body plate 14 is respectively provided with a second connecting groove (not shown in the figure). The receiving plate 30 is correspondingly connected to the second connecting groove 135 of the first main body plate 13 and the second connecting groove of the second main body plate 14.

[0032] In this embodiment, the receiving plate 30 is connected to the first main plate 13 and the second main plate 14 via a slot structure, resulting in a tighter and more stable connection. It can be understood that the slot connection structure can be achieved through welding, riveting, gluing, etc., and the receiving plate 30, the first main plate 13, and the second main plate 14 can also be an integral structure.

[0033] Furthermore, the first main body plate 13, the second main body plate 14, the connecting plate 15, and the receiving plate 30 are each provided with a hollowed-out area. In this embodiment, setting the plate-like structure as a hollowed-out structure is beneficial for the weight reduction of the device.

[0034] Further, the first main body plate 13, the second main body plate 14, and the connecting plate 15 form an extended connecting groove 16 for connecting the trailer hook 200. In this embodiment, the first main body plate 13, the second main body plate 14, and at least two connecting plates 15 intersect to form an extended connecting groove 16. Correspondingly, the square tube 201 of the trailer hook 200 is inserted into the extended connecting groove 16. The trailer hook 200 achieves a limiting connection with the main body 10 through a limiting rod 202 and a pin 203. The limiting rod 202 passes through the first main body plate 13 and the square tube 201 of the trailer hook 200, and the pin 203 is inserted into the limiting rod 202 to achieve limiting.

[0035] Furthermore, the first main body plate 13, the second main body plate 14, the connecting plate 15, the hanging plate 20 and the receiving plate 30 are connected together by welding.
