[0023] In this embodiment, the mounting plate 9 is fixedly mounted on one side of the machine body 1 and the position of the mounting plate 9 corresponds to the work surface 2. Support blocks 14 are fixedly mounted on the four corners of the bottom of the machine body 1. The mounting plate 9 can facilitate the installation of the protective plate 10; the bearing 1102 is embedded in the bottom of the adjusting groove 1101, and the bottom end of the threaded rod 1103 passes through and is fixed on the inner ring of the bearing 1102 and then extends out of the mounting plate 9.

[0024] The working principle and use process of the utility model: the operator first checks whether the relevant components are installed in the correct position, and rotates the three groups of handles 1107 in sequence to drive the synchronous rotation of the corresponding threaded rods 1103, thereby driving the protective plate 10 to move up and down, and making the protective plate 10 finally completely located in the mounting plate 9. At this time, the protective plate 10 will not affect the placement of the metal sheet, and the metal sheet is placed on the supporting plate 3, and one end of the metal sheet is located on the placement plate under the several groups of pressing mechanisms 5. The pressing mechanism 5 can press and fix the metal sheet, and rotate the three groups of handles 1107 in sequence so that the top ends of the three groups of protective plates 10 are completely extended out of the mounting plate 9. The "plum blossom-shaped" design of the handle 1107 can make the rotation of the handle 1107 easier, and the operation of the hydraulic telescopic rod 7 is controlled by the control panel 6 to move the shear knife 4 downward. Metal sheets are sheared.
