[0013] Preferably, the second connecting plate is a square plate structure, and bolts can pass through the threaded holes on the first connecting plate to the threaded holes on the second connecting plate, threading the first connecting plate and the second connecting plate to fix the cutter on the tool holder.
[0014] Preferably, the first limiting block is in a "convex"-shaped structure, and the first limiting block can be inserted into the limiting groove to limit the displacement of the second limiting block.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] The utility model discloses a cutting mechanism for a fancy twisting machine. First, the first connecting plate on the cutter is used to insert the cutter into the groove on the knife holder, which makes the installation of the cutter more convenient. During the installation and disassembly of the cutter, the worker can directly grasp the first connecting plate, thus avoiding contact with the blade of the cutter and reducing the risk of the worker being cut. Subsequently, the first connecting plate on the knife holder is threadedly connected with the second connecting plate on the cutter by bolts, so that the worker can install or disassemble the cutter more conveniently.

After that, the first limit block is pulled out to allow the sliding block to move to the appropriate position. Thereafter, the first limit block is reinserted into the limit groove, so that the second limit block and the sliding block are fixed. Therefore, by moving the position of the sliding block, the tightness of the yarn cutting point can be changed, avoiding the failure of cutting due to the yarn being too loose, resulting in uneven yarn cutting, and thus leading to an increase in the product defective rate. On the contrary, if the yarn is too tight, the yarn may be entangled after the yarn is cut, requiring additional manpower to handle, which will also reduce the work efficiency of the production line.
