[0033] In the utility model, the length direction of the assembly groove is neither parallel to the length direction of the placement area and the support block, nor perpendicular to the length direction of the placement area and the support block, so that the punching knife can change its position with the support block by changing its position in the assembly groove, which is convenient for the operator to adjust the punching knife; at the same time, when the first movable block and the second movable block drive the punching knife to perform punching and cutting, the inclined inner wall of the assembly groove can also provide sufficient supporting force for the punching knife.

[0034] In the utility model, the movable groove is provided to improve the movable stability of the movable part, thereby improving the movable stability of the first movable block and the second movable block.

[0035] In the present invention, the assembly of the limiting assembly itself is realized by setting the limiting mounting member; and the limiting contact member and the pressure member are set to achieve the limiting force applied to the frame.

[0036] In the utility model, the feeding guide block is provided so that the skeleton can enter the placement area more stably to cooperate with the support block; at the same time, when the skeleton is punched, a certain limiting force can be applied to the skeleton through the feeding guide block.

[0037] In the utility model, the base is provided with a waste outlet hole penetrating the upper and lower surfaces thereof; the support block is located above the waste outlet hole, so that the waste generated by punching and cutting can leave the base easily.

[0038] In the utility model, the support block is detachably connected to the base, so that the corresponding support block can be replaced according to the different shapes of the space inside the frame, so that the utility model can perform punching work on more types of frames, thereby improving the scope of application of the utility model.
