[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4The utility model provides a technical solution: a woodworking edge banding chamfering tool, comprising: a tool body 1 and a blade 2, the tool body 1 is L-shaped, and a 3D grip 14 is integrally provided on one side of the angle of the tool body 1, and the 3D grip 14 can better apply force to the tool body 1 by hand;

[0029] The upper surfaces of the two outer sides of the tool body 1 are respectively provided with a first scale mark 12 and a second scale mark 13;

[0030] The first scale mark 12 is used to measure the extension of the blade 2, and the second scale mark 13 is used to measure the size when chamfering woodworking;

[0031] A knife groove 15 is provided on the upper surface of the tool body 1, and a blade 2 is slidably arranged in the knife groove 15, and the front end of the blade 2 passes through the knife groove 15. The knife groove 15 is located on the side wall of the blade surface and is concavely designed to form a strip groove 151 for accommodating the edge of the blade 2. The knife groove 15 hides the blade 2 in the tool body 1 to avoid accidental injury.

[0032] The cutting edge direction of the knife groove 15 is tilted downward by 7.5 degrees, so that the blade 2 is tilted at a certain angle, reducing the moment of the blade 2 and making it easier for the blade to cut into the object;
