[0002] The hydraulic hoof shears are industrial equipment specially used for shearing cattle hooves in the slaughtering industry. They adopt the hydraulic transmission principle and use the pressure of the hydraulic system to drive the opening and closing of the blade to achieve the purpose of shearing cattle hooves. The hydraulic hoof shears are equipped with a double-handle safety switch to ensure that both hands must be pressed at the same time to start the operation, which greatly improves the safety of operation. It is suitable for large and medium-sized slaughtering enterprises and can meet the needs of slaughterhouses of different sizes.

[0003] In the patent application number 201610728482.1, a hydraulic pipe shear is disclosed. The controller, hydraulic pump and hydraulic cylinder provided in the pipe shear in the application not only change the shearing power mode, but also achieve a manual control mode of hydraulic power to complete the machine operation. The operation steps are convenient and quick, which shortens the construction preparation and operation time. At the same time, the requirements for the shearing operation environment are low, and the construction operation area is large. In combination with the above application, and compared with the existing cow hoof hydraulic shears, when using the existing cow hoof hydraulic shears, the scissor arms on the hydraulic shears are usually cut by crossing. In the process of shearing hard objects, the cutting edge may be misaligned, which affects the shearing effect of the scissors and also affects its practicality and stability. For this reason, we propose the cow hoof hydraulic shears. Utility Model Content
