Anti-rotation oil cylinder

The utility model provides an anti-rotation oil cylinder which comprises an installation base, an oil cylinder body, an oil cylinder cover and an oil cylinder cover. One end of the cylinder body is a spherical mounting end, and the mounting end is located in the spherical cavity so as to be hinged to the mounting base; the anti-rotation block is fixed on the mounting base, and the anti-rotation block is provided with a limiting groove; and the anti-rotation head is fixed to the cylinder body, and the anti-rotation head is matched with the limiting groove in a limiting mode so that the cylinder body can be limited in the circumferential direction. According to the scheme, the cylinder body and the mounting base are in spherical hinge fit, so that the cylinder body can swing within a certain range relative to the mounting base, and the use requirement is met; moreover, through cooperation of the anti-rotation head and the anti-rotation block, the circumferential position of the cylinder body is limited, the cyl
