The fixing block 704 is fixedly connected to the side of the two limiting plates 703 that are close to each other.

[0028] In this embodiment: by setting the limiting component 7, the bidirectional lead screw 701 rotates and drives the threaded sleeves 702 on both sides of its surface to move relative to or opposite to each other. When the threaded sleeves 702 move, they will drive the limiting plate 703 to move together, so that when the two limiting plates 703 approach the bending die 5, they can clamp and fix the bending die 5. Since the opposite side of the limiting plate 703 is made of rubber, when the limiting plate 703 contacts the two sides of the bending die 5, it can produce a certain elastic deformation, thereby improving the fixing effect. Then, according to the usage requirements, the bending die 5 can be flexibly clamped or loosened to facilitate the replacement of the bending die 5.

[0032] In the embodiment, the positioning assembly 8 is arranged, the insertion rod 801 can be matched with the positioning groove 11, the accurate fixing of the bending die 5 in the horizontal direction and the vertical direction is realized, the lifting ring 803 facilitates the manual operation of the insertion rod 801, when the bending die 5 needs to be replaced, the operator can easily hold the lifting ring 803 and pull up the insertion rod 801, so that the insertion rod 801 is pulled out of the positioning groove 11, the pulling force of the positioning tension spring 804 can keep the insertion rod 801 in the positioning groove 11, the stability of the positioning is ensured, the moving block 802 provides support and guiding effect for the insertion rod 801, it is ensured that the insertion rod 801 can be vertically inserted into or pulled out of the positioning groove 11, and the moving block 802 can be flexibly moved, so that the insertion rod 801 can be adaptively adjusted according to the actual position of the positioning groove 11 in the process of being inserted into the positioning groove 11, and the use flexibility is improved.

[0033] Specifically, as shown in Figure 3 The bottom of the insertion rod 801 is fixedly connected with a U-shaped frame 12, the U-shaped frame 12 is rotatably connected with a roller 13, and the roller 13 is used in cooperation with the positioning groove 11.
