[0002] A semitrailer is a trailer with its axle positioned behind the vehicle's center of gravity (when evenly loaded) and equipped with a hitch that transmits horizontal and vertical forces to the towing vehicle. It is primarily used to transport bulky, difficult-to-disassemble cargo, such as excavators. Barrier-type trailers are more suitable for hauling fresh goods, such as vegetables and fruit. Box-type trailers are more suitable for hauling bulk cargo and moisture-resistant, valuable goods.

[0003] For example, a detachable goose head structure for a semi-trailer, such as that disclosed in patent application number CN202122498477.5, comprises a flatbed truck body, a mounting bracket fixedly connected to the top of one end of the flatbed truck body, a bracket fixedly connected to one end inside the mounting bracket, a hydraulic rod rotatably connected inside the bracket, positioning seats fixedly connected to both sides of the inner wall of the mounting bracket, a goose head body arranged between the two positioning seats, a fixing bracket fixedly connected to the inside of the goose head body, a connecting head embedded in the bottom of the end of the goose head body away from the flatbed truck body, and a fixing plate arranged at the bottom of the connecting head. The utility model cooperates with each other between the hydraulic rod, the mounting bracket, and the bracket, and a hydraulic rod is arranged inside the goose head and before the flatbed truck, and the goose head is connected by a detachable rotating shaft. When the user assembles the semi-trailer, he only needs to control the hydraulic rod to drive the goose head to deflect, thereby facilitating the adjustment of its assembly direction and improving the installation efficiency of the goose head.

[0004] Although the above-mentioned detachable goose head structure for a semi-trailer can improve the installation efficiency of the goose head, its installation stability is relatively poor. Utility Model Content
