[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0016] Please refer to Figs. 1-3 A blade convenient to adjust the chip removal angle, comprising a handle 1, the end of the handle 1 is fixedly connected with a cutting head 2, preferably, the cutting head 2 and the handle 1 are fixed by welding.

[0017] The cutting head 2 is provided with an angle adjusting plate placing groove 3, and the angle adjusting plate placing groove 3 is detachably fixed with an angle adjusting plate 4,

[0018] Among them, the top surface of the angle adjusting plate 4 is an inclination adjusting surface 42, the side surface is a fitting surface 41, and the fitting surface 41 and the side wall of the angle adjusting plate placing groove 3 completely match. The inclination adjusting surface 42 of the angle adjusting plate 4 and the top of the cutting head 2 form a V-shaped chip removal groove.

[0019] The angle adjusting plate 4 is provided with a counter-sunk screw hole 6, and the angle adjusting plate placing groove 3 is correspondingly provided with a mounting screw hole 5, the angle adjusting plate 4 and the cutting head 2 are fixed by screwing the counter-sunk screw hole 6 and the mounting screw hole 5, and are conveniently installed and removed by screw connection.

[0020] Working principle: the blade convenient to adjust the chip removal angle of the utility model, when in use, the cutting head 2 cuts the workpiece, and the iron filings generated by cutting are discharged from the V-shaped chip removal groove, wherein the V-shaped chip removal groove can replace different angle adjusting plates 4 to generate different inclination adjusting surfaces 42 to meet the cutting conditions.

[0021] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
