[0026] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.
[0027] When in use, first manually push the first connecting block 4 to slide along the first groove on one side of the first support plate 1, and the first slider 26 slides inside one side of the first slideway 27 to provide a movement track and space for the first connecting block 4, and then the first connecting rod 3 is driven to rotate under the movement of the first connecting block 4, and the first limiting block 5 is driven to rotate under the rotation of the first connecting rod 3. Through the displacement of multiple first limiting blocks 5, it is convenient to fix the position of the first support plate 1, thereby achieving the effect of increasing the stability of the first support plate 1.

The effect of grabbing and limiting the material is achieved by the rotation of multiple fifth connecting rods 19, and then when one side of the material is in close contact with one side of the fourth connecting block 22, the sixth connecting rod 21 is driven to rotate, thereby driving the first clamping block 20 to rotate, and then through the cooperation of the movement of the fifth connecting rod 19 and the sixth connecting rod 21, multiple first clamping blocks 20 and one side of the second clamping block 23 are simultaneously driven to be in close contact with the surface of the material, thereby achieving the effect of increasing the contact area.
