[0002] A complete hydraulic system consists of five parts, namely power elements, actuators, control elements, auxiliary elements (accessories) and hydraulic oil. At present, hydraulic systems can be divided into two categories: hydraulic transmission systems and hydraulic control systems. Among them, the hydraulic transmission system is mainly used to transmit power and motion, while the hydraulic control system is to make the hydraulic system output meet specific performance requirements.

[0003] Each component of the hydraulic system is connected by hydraulic pipes to allow the hydraulic medium to flow between the parts. Therefore, pipeline damage is also one of the common faults of the hydraulic system. During maintenance, the damaged pipes need to be cut and replaced.

Although the operation is simple and convenient, due to the lack of positioning between the cutting equipment and the pipe, it is difficult to ensure the stability of the cutting equipment during handheld operation. Therefore, the cutting of the pipe is usually uneven and of poor quality. It takes a lot of time to grind, which is time-consuming and labor-intensive and needs to be improved. Utility Model Content
