[0025] Specifically, the base of the product is fixed in the carrier table 22, and then the upper cover of the product is placed on the base, the outer wall of the base is provided with external threads, and the inner wall of the upper cover is provided with internal threads. The screw 44 provides a pulling force to the steel wire 41, the steel wire 41 tightens the connecting part 42 and the connecting plate 23 through the tensioning assembly 43, and the connecting plate 23 abuts against the limiting pin 24. When the screwing mechanism drives the upper cover of the product to rotate and press down, the internal threads of the upper cover are connected with the external threads of the base through rotation, so that the upper cover and the base are tightened. The rotation direction of the rotating mechanism is opposite to the pulling direction of the screw 44, when the upper cover and the base are tightened in place, the rotating force of the tightening mechanism 3 is greater than the pulling force of the screw 44, the carrier table 22 is driven to move the connecting plate 23 in the opposite direction of the limiting pin, and the tightening mechanism 3 receives the movement signal of the position sensor 5 and stops working in time.
