[0025] The height of the tool 4 can be adjusted by the lifting plate 2 on the top of the workbench 1, and at the same time, the clamping plate 3 is used to facilitate the user to disassemble and assemble the tool 4. When it is necessary to shear the components, the conveying plate 6 will drive the positioning plate 7 and the auxiliary plate 8 to move, accurately position the components and convey them to the shearing position. When the components are conveyed to the specified position, the lifting plate 2 descends, driving the positioning mechanism 5 to contact the components, and continues to descend to achieve precise positioning, thereby positioning the shearing part of the components and improving the shearing quality of the tool 4.

A hydraulic cylinder is provided at the top center of the top plate 10, and the output end of the hydraulic cylinder is connected to the mounting seat on the top of the lifting plate 2.
[0027] The top plate 10 is installed by positioning bolts, which is convenient for users to disassemble and assemble the device.
