Hydraulic cylinder and vehicle

The hydraulic cylinder comprises a cylinder body with a containing cavity and a piston rod assembly, the piston rod assembly comprises a rod body, a piston body and an adjusting piece, the piston body is connected with the rod body, at least part of the end, facing the piston body, of the rod body extends into the containing cavity and is movably connected with the cylinder body, and the adjusting piece is arranged between the rod body and the piston body. The adjusting piece is used for adjusting the distance between the rod body and the piston body. According to the hydraulic cylinder and the vehicle, the distance is adjusted through the adjusting piece arranged between the rod body and the piston body, the movement stroke of the piston body in the containing cavity can be adjusted, and therefore the hydraulic cylinder can adapt to different working requirements, and the applicability of the hydraulic cylinder is improved. 本发明涉及一种液压缸及车辆，包括具有一容纳腔的缸体和活塞杆组件，活塞杆组件包括杆体、活塞本体以及调节件，活塞本体与杆体相连，杆体朝向活塞本体的一端至少部分伸入容纳腔，且与
