A linkage spur gear 12 is fixedly connected to the outer side of the linkage shaft rod 11, and each linkage spur gear 12 is meshed with the driving spur gear 10. A limiting seat 13 corresponding to the linkage spur gear 12 is fixedly connected to the inner wall of the bottom end of the locking column 4. A locking shaft rod 14 is slidably connected to the middle of the limiting seat 13, and the locking shaft rod 14 is snap-connected to the lock slot 5. A guiding rack 15 is fixedly connected to one end of the locking shaft rod 14 close to the central shaft rod 8, and the guiding rack 15 is also meshed with the corresponding linkage spur gear 12;

[0028] Further, a through hole adapted to the locking shaft rod 14 is formed in the outer side of the bottom end of the locking column 4, and the diameter of the through hole is larger than the diameter of the locking shaft rod 14, so that the locking shaft rod 14 can pass through the through hole and move out of the locking column 4;

[0030] Embodiment Two:

[0031] Please refer to Figures 2-5 , this embodiment provides a technical solution on the basis of Embodiment One: The transmission assembly 7 includes an assembly seat 16, a transmission shaft rod 17, a threaded section 18 and a displacement push plate 19. An assembly seat 16 is fixedly connected to the middle of the bottom end of the mold body 1. A transmission shaft rod 17 is rotatably connected inside the assembly seat 16. Threaded sections 18 are formed at both ends of the outer side of the transmission shaft rod 17, and the thread directions of the two threaded sections 18 are opposite. Displacement push plates 19 are threadedly connected to the outer sides of the two threaded sections 18.

[0036] Working principle: First, fix the positioning base plate 2 at the specified position through the connecting piece, then place the mold body 1 on the positioning base plate 2 with the help of tools, and move the locking column 4 into the corresponding locking groove 5;

[0037] By rotating the transmission shaft 17 and cooperating with the setting of the two threaded sections 18 with opposite spiral rotation directions, the rotation of the transmission shaft 17 can be used to drive the two displacement push plates 19 to move toward each other. Since the linkage rod 20 is connected between the displacement push plate 19 and the guide plate 9, when the displacement push plate 19 is displaced, the linkage rod 20 can be used to push the guide plate 9, and since the guide plate 9 is supported by the central shaft 8, the central shaft 8 can be driven to rotate, prompting the transmission spur gear 10 to shift multiple linkage spur gears 12, and then the guide rack 15 is shifted through the linkage spur gear 12, prompting the guide rack 15 to drive the locking shaft 14 to move out of the locking column 4 and get stuck in the locking groove 5, thereby locking the locking column 4 in the locking groove 5, and finally completing the fixation of the position of the mold body 1.
