[0003] For example, a vehicle-mounted square cabin leg assembly disclosed in a utility model patent with patent announcement number CN217374448U discloses a vehicle-mounted square cabin leg assembly, including a front supporting leg group and a rear supporting leg group. The front supporting leg group and the rear supporting leg group have the same structure. The front supporting leg group includes supporting leg A and supporting leg B, and supporting leg A and supporting leg B are symmetrical structures. The rear supporting leg group includes supporting leg C and supporting leg D, and supporting leg C and supporting leg D are symmetrical structures. Support leg A and support leg C have the same structure. Support leg A includes a telescopic leg, and the telescopic leg is a rectangular frame. A hollow vertical frame is arranged at the upper end of the telescopic leg, a base is arranged at the lower end of the telescopic leg, and a horizontal bracket A is arranged at the upper end of the vertical frame. The telescopic leg adopts a pull-out and telescopic structure, which is easy to cause the leg to tilt during use, and the overall force on the square cabin legs is uneven. Therefore, a leg with a simple structure and a good verticality is needed. Utility Model Content

The hydraulic cylinder with the supporting base plate is rotated by rotating the connected fixing parts and the connecting parts, and can be fixed after rotation by cooperating with the locking pin and the locking hole.

[0006] Furthermore, there are multiple pin holes and they are arranged around the rotational connection between the connecting member and the fixing member, so that the connecting member and the fixing member can be rotated and fixed at multiple angles.

[0007] Furthermore, the spacing angle between every two adjacent pin holes is 90°, which facilitates opening the legs at 90°.

[0008] Furthermore, the output end of the hydraulic cylinder is a ball head, and the support base plate is connected to the ball head in a ball head manner. The support plate connected via the ball head facilitates a better fit when the support plate contacts the ground.

[0009] Furthermore, the oil inlet and outlet pipelines of the hydraulic cylinder are connected with a hydraulic lock, which prevents the hydraulic cylinder from hydraulic failure.

[0010] Furthermore, an annular stopper is provided on the locking pin, a spring is sleeved on the locking pin, an outer shell is provided around the annular stopper and the spring, the lower end of the locking pin passes through the lower part of the outer shell, the upper part of the outer shell is fixed to the connecting piece, and the locking pin is pushed into the pin hole by the spring.

[0011] Furthermore, a handle is fixedly mounted on the lower end of the locking pin to facilitate the insertion and extraction of the locking pin from the pin hole.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model rotates the fixing part and the connecting part with the hydraulic cylinder supporting the bottom plate through rotation, and can be fixed after rotation through the lock pin and the lock hole. The hydraulic cylinder is directly used, which has a simple structure and good verticality, and is not easy to tilt compared with the casing legs. BRIEF DESCRIPTION OF THE DRAWINGS
