It is easy to use and saves time and effort. When the bidirectional threaded rod 23 is driven to rotate by the rotating block 24, the moving block 21 can be driven to move inward or outward on the outer surface of the bidirectional threaded rod 23. When the moving block 21 moves, it can drive the guide rod 22 to move, so that according to the situation of the plastic product, when it enters the traction seat, position limitation and guidance can be achieved, thereby ensuring the stability of the plastic product during demoulding and traction.
