The movable block 42 is provided with a sliding rod 43, and the sliding rod 43 can slide in the rotating block 42. One end of the sliding rod 43 is rotatably connected to the rotating rod 44. The ends of the two rotating rods 44 are rotatably connected to the clamping block 45. A supporting column 7 is provided between the bottom plate 41 and the rotating block 42. By providing the clamping assembly 4, it will not affect the normal cutting of the workpiece, and the position of the clamping block 45 can be changed at will to clamp and limit the workpiece, thereby increasing its placement stability and reducing the probability of the workpiece being offset by external force and affecting the cutting accuracy. The entire assembly is convenient for installation and disassembly.

[0022] In this embodiment, preferably, the upper end of the support column 7 extends into the rotating block 42, and the rotating block 42 rotates to facilitate the adjustment of the position of the clamping block 45, and the two are connected by a set bearing. The support column 7 is a rubber column, and the rubber column can be easily stretched slightly upward, so that the clamping block 45 can move slightly upward without contacting the workpiece, thereby facilitating the movement of the clamping block 45.

[0023] In this embodiment, preferably, the sliding rod 43 and the rotating rod 44 are connected by a set rotating shaft to facilitate the change of the position of the clamping block 45. A clamping block is fixed at the end of the rotating rod 44. The rotating rod 44 and the clamping block are connected by a set rotating shaft. An adjustment component 6 is provided between the clamping block and the clamping block 45.

[0024] In this embodiment, preferably, the adjusting component 6 includes a fixed convex plate 61, a fixed frame 62, a sliding rod 63 and a limiting ring 64. The fixed frame 62 is fixed on the surface of the card block and is "U"-shaped when viewed from the side. Rectangular sliding holes are provided on the front and rear surfaces of the fixed frame 62 along its height. The fixed convex plate 61 is fixed to the side of the clamping block 45. The front and rear surfaces of the end of the fixed convex plate 61 are fixed with a sliding rod 63. The end of the sliding rod 63 can move through the rectangular slider to be exposed to the outside, and the end is threadedly screwed with a limiting ring 64.

[0027] Working principle and use process of the present invention: When the present invention is in use, the entire clamping assembly 4 can be fixed to the top of the frame 1 by screws. At this time, the clamping block 45 can be placed on the workpiece, and the limiting ring 64 is sleeved on the end of the slide rod 63 and contacted with the fixing frame 62 to limit the position, so as to limit and tighten the height position of the clamping block 45. The clamping assembly 4 is used to clamp and limit the workpiece to prevent it from shifting. If the position of the clamping block 45 needs to be changed, the clamping block 45 can be held and lowered and slightly lifted upward, which indirectly drives the rotating block 42 to move upward, and the support column 7 is stretched, and the lifted clamping block 45 is lifted upward. The block 45 can be easily moved to change the clamping position, and during the movement, the sliding rod 43 slides in the rotating block 42, and the sliding rod 43 and the rotating rod 44 form an angle change. When the moving position is appropriate, the clamping block 45 is released, the support column 7 recovers its elasticity, and the clamping block 45 is pressed tightly on the workpiece again. By providing the clamping assembly 4, it does not affect the normal cutting of the workpiece, and the position of the clamping block 45 can be changed at will to clamp and limit the workpiece, thereby increasing its placement stability and reducing the probability of the workpiece being offset by external force and affecting the cutting accuracy, and the entire assembly is easy to install and disassemble.
