[0002] In the process of bending workpieces, a bending die is needed; in order to quickly replace a damaged bending die, a replacement mechanism for detachably fixing the bending die needs to be provided on the die base. Although the existing replacement mechanism of the bending die can meet the basic demand for flexible fixing of the bending die, the connection between the bending die and the die base is usually fixed by a spring clamping structure. During use, it is easy to be unable to continue to achieve or release the fixation of the connection between the bending die and the die base due to damage to the spring and the inability to adjust the extension normally, which brings great inconvenience to people's use.

[0003] For example, the utility model with the announcement number CN 219335651 U discloses a quick-change bending die. In the technical solution of this patent, the connection between the bending die and the die base is flexibly fixed by the cooperation of a spring guide column, a spring and a clamping block. During use, after a period of use, the spring is easily unable to be normally extended and adjusted, which leads to the inability to continue to achieve or release the effective fixation of the connection between the bending die and the die base. Therefore, there are defects such as insufficient stability and short service life, which cannot fully meet people's usage needs. Utility Model Content
