Anti-unbalance-loading hydraulic oil cylinder with adjustable stroke

The stroke-adjustable unbalance-load-resistant hydraulic oil cylinder comprises a cylinder barrel, a cylinder bottom connected with one end of the cylinder barrel in a sealed mode, a piston connected with the inner side wall of the cylinder barrel in a sliding and sealed mode, a piston rod with the first end fixedly connected with the piston, and a guide sleeve connected with the second end of the piston rod. The guide sleeve is in sliding sealing connection with the inner side wall of the cylinder barrel, and a stroke adjusting mechanism is arranged at the end, away from the cylinder bottom, of the cylinder barrel. The stroke adjusting mechanism comprises a supporting cylinder slidably connected with the inner side wall of the cylinder barrel, a sliding block slidably connected with the inner side wall of the supporting cylinder and used for being fixedly connected with an external load and an adjusting disc used for adjusting the relative position of the supporting cylinder and the cylinder barrel, and the
