[0005] To achieve the above objectives, the utility model provides the following technical solutions: an indexable cutting blade, comprising a main blade, the upper surface of the main blade is provided with a slide groove, a plurality of auxiliary blades are evenly distributed above the slide groove, and a clamp plate is provided above the auxiliary blades.
[0006] As a further solution of the utility model: a clamp pin is fixedly connected to the middle part of the inner side of the clamp clamp plate, and a positioning screw hole is opened in the middle part of the clamp pin.
[0007] As a further solution of the utility model: a sliding block is slidably connected to the inner side of the sliding groove, and the top of the sliding block is fixedly connected to the middle part of the bottom end of the auxiliary blade.
[0008] As a further solution of the utility model: a push-adjustment column block is fixedly connected to the middle of the top end of the auxiliary blade, and a push-adjustment cavity groove is slidably connected to the outer side of the push-adjustment column block.
[0009] As a further solution of the utility model: the outer side of the push-adjustment cavity is fixedly connected to the clamping plate, and the number of the push-adjustment cavity matches the number of the auxiliary blades.
[0010] As a further solution of the utility model: a clamp cavity is opened in the middle of the main blade, and the inner side of the clamp cavity is rotatably connected to the lower side of the positioning screw hole.
[0011] As a further solution of the utility model: a drainage groove is provided on the upper surface of the clamp plate.
[0012] Compared with the prior art, the utility model has the beneficial effects of facilitating and quickly adjusting the sharpness of the cutting blade, which is beneficial to improving the use effect of the cutting blade.
[0013] By providing the main blade, auxiliary blade, slide groove and clamping plate, when in use, when a sharp blade is not needed for cutting, the main blade cuts the metal to be cut. When a sharp blade is needed for cutting, the rotating clamping plate drives the auxiliary blade to slide along the slide groove to the corner corresponding to the main blade, and folds the blade at the corner of the main blade. At this time, the auxiliary blade cuts the metal to be cut, which makes it easy to quickly adjust the sharpness of the cutting blade and is beneficial to improving the effect of using the cutting blade.
