（二）背景技术 (2) Background technology

目前，液压油缸极广泛地应用于各行各业，普通的液压油缸在伸缩动作时，由于载荷偏心，圆周配合不均等原因，导致活塞杆动作时会产生一定的自转，产生复合了旋转的直线运动。当由于工作需要，活塞杆安装时没有对活塞杆进行联结约束，但需要输出精确的不附带旋转的直线运动时，活塞杆的防旋转就变得极为重要。然而，现有技术中，液压油缸内防旋转的机构大多结构复杂，使用寿命短，安装不方便，且防旋转效果不理想，成本较高。 At present, hydraulic cylinders are widely used in all walks of life. When ordinary hydraulic cylinders are stretching, due to load eccentricity and uneven circumference fit, the piston rod will rotate to a certain extent when it moves, resulting in linear motion combined with rotation. . When the piston rod is installed without coupling constraints due to work requirements, but it is necessary to output precise linear motion without rotation, the anti-rotation of the piston rod becomes extremely important. However, in the prior art, most of the anti-rotation mechanisms in the hydraulic cylinder have complex structures, short service life, inconvenient installation, unsatisfactory anti-rotation effect, and high cost.
