According to the parts of the parts, the user can select a suitable clamping mechanism. When the second clamping mechanism 4 is needed, the first motor 406 is started to make the two T-shaped sliding blocks 403 approach each other. Under the action of the clamping plate 405, the parts are fixed and the cutting is achieved. When the first clamping mechanism 3 is needed, the first motor 406 is started to reverse, so that the two T-shaped sliding blocks 403 are separated from each other.
