All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 and Figure 2 , the present utility model provides a technical solution: a threading die convenient for positioning and docking, including a connecting sleeve 1, a threaded core rod 2 and a motor 7. The top end of the connecting sleeve 1 is provided with a threaded core rod 2, and a first gear 3 is sleeved below the connecting sleeve 1. One side of the first gear 3 is connected with a gear shaft 4. The bottom end of the connecting sleeve 1 is docked with a mounting plate 5, and a connecting shaft 6 is connected to the upper side of the mounting plate 5 far away from the connecting sleeve 1 through a bearing seat. The connecting shaft 6 and the gear shaft 4 are connected through the cooperation of a belt and a pulley. A motor 7 docked with the connecting shaft 6 is installed at the bottom of the mounting plate 5, and a docking mechanism 8 is jointly arranged between the connecting sleeve 1 and the threaded core rod 2. The docking mechanism 8 includes a mounting groove 81, a docking groove 82, a docking column 83, a limiting block 84, a guiding rod 85, a spring 86, a mounting seat 87 and a fastening pin 88.

The limiting block 84 and the docking post 83 form a telescopic structure through the spring 86. The size of the docking groove 82 matches the size of the docking post 83, and the docking post 83 and the docking groove 82 are in plug-in connection.

[0024] During specific implementation, first, the fastening pin 88 is screwed outward to the extreme position, and then the docking post 83 in the mounting groove 81 is inserted into the docking groove 82 in the threaded core rod 2, and the threaded core rod 2 is pressed downward. The downwardly pressed threaded core rod 2 will squeeze the side wall of the limiting block 84. The externally squeezed limiting block 84 will move inward along the guide rod 85 into the docking post 83. The moving limiting block 84 squeezes the spring 86 sleeved on the outer side of the guide rod 85 until the threaded core rod 2 is pressed inward to the extreme position. The limiting block 84 corresponds to the reserved notch on the inner wall of the threaded core rod 2.
