[0035] In summary, the working principle of a hydraulic billet shear that is easy to disassemble the oil cylinder in the embodiment of the utility model is as follows: when the oil cylinder body 205 needs to be installed, the staff first rotates the oil cylinder body 205 to install its output end with the pushing seat 601. After the staff adjusts the rotating seat 201 to a suitable position, the two clamping plates 204 clamp the oil cylinder body 205, and place the oil cylinder in a position that is easy to reach and operate, which can reduce the difficulty of disassembling and installing the oil cylinder. After installation, the staff presses the pressing plate 303, and the pressing plate 303 pushes the limit slide bar 302 to slide on the fixed block 301, so that the limit slide bar 302 is brought into contact with the fixed block 301.

[0037] The cylinder body 205 pushes the pushing seat 601 and the connecting shaft 602 to move, and the connecting shaft 602 pushes the billet shear 603 to cut the object. When the billet shear 603 moves with the limit hinge shaft 604 as the axis, the billet shear 603 drives the L-shaped push-pull plate 605 to move, and the L-shaped push-pull plate 605 pulls the pull plate 607 to move through the hinge rod 1 606, and the pull plate 607 pulls the convex slide plate 609 to move through the hinge rod 2 608, and the convex slide plate 609 slides on the concave guide rail 610, and the concave guide rail 610 drives the protective rod 611 to squeeze the object, so that the object is fully in contact with the billet shear 603, to prevent the object from being squeezed by the billet shear 603 and detaching from the device.
