The ball grooves on the upper surface of the sheet metal table 12 are rotatably connected with universal balls 13. The universal balls 13 rotate in the ball grooves on the upper surface of the sheet metal table 12 to reduce the friction force on the metal sheet during the movement of the sheet metal table 12.

[0023] Safety protection mechanism 4: It includes a slide 41, a slide plate 42, a mounting shell 43, a rotating column 44, a protective frame 45 and a torsion spring 46. The slide 41 is respectively arranged at the upper end of the front surface of the shearing machine housing 1. The interior of the slide 41 is slidably connected to the slide plate 42. A mounting shell 43 is provided between the front ends of the slide plate 42. The interior of the mounting shell 43 is rotatably connected to the rotating column 44. A protective frame 45 is provided at the lower end of the rotating column 44. The left and right ends of the outer arc surface of the rotating column 44 are movably sleeved with torsion springs 46.
