[0021] 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.

[0022] Example: See Figure 1-5 The utility model provides a technical solution: a carbide woodworking milling cutter. The application is mainly aimed at improving the problem that the existing milling cutter and the rod sleeve are connected in a fixed manner and the length cannot be adjusted. When the milling cutter head has a certain length left, it becomes unusable, which not only wastes a large amount of carbide materials, but also greatly increases the manufacturing cost of the tool. The specific scheme is as follows: it includes a movable sleeve 1 3, a movable sleeve 2 1 and a milling cutter 2, and the centers of the movable sleeve 1 3, the movable sleeve 2 1 and the milling cutter 2 are collinear. Among them, the movable sleeve 1 3 is fixedly installed on the output shaft of the electric tool, and the movable sleeve 2 1 is movably plugged into the movable sleeve 1 3.

[0023] See also Figure 1 and Figure 3 , wherein a guide rod 12 is provided inside the movable sleeve 2 1, the guide rod 12 and the movable sleeve 1 3 can be processed as one piece, and a corresponding notch groove is provided in a ring shape on the outer side of the guide rod 12. The notch groove is provided to facilitate the rotation of the milling cutter 2 relative to the guide rod 12. After connection, the milling cutter 2 can only move along the axis of the movable sleeve 1 3.

[0024] Furthermore, a plug-in slot 21 for the guide rod 12 to be engaged is provided on the milling cutter 2, and the centers of the milling cutter 2 and the guide rod 12 are colinear.

[0025] Furthermore, an adjusting screw 11 is threadedly connected inside the guide rod 12, and the length of the adjusting screw 11 is greater than the length of the guide rod 12. The adjusting screw 11 is arranged inside the guide rod 12, and the adjusting screw 11 and the guide rod 12 are both arranged inside the movable sleeve 1. The milling cutter 2 is movably plugged into the guide rod 12. After the adjusting screw 11 is rotated, the milling cutter 2 can move along the axis on the guide rod 12. When the milling cutter 2 is worn and shortened, the position of the milling cutter 2 on the guide rod 12 can be adjusted so that the milling cutter 2 can be withdrawn from the movable sleeve 1 3, which can facilitate the full use of the milling cutter 2 and reduce the use cost of the milling cutter 2. It is worth promoting and using.

[0026] See also Figure 1 , Figure 3 and Figure 4The end of the movable sleeve 1 3 corresponding to the movable sleeve 2 1 is provided with a guide groove 31 and a limit groove 32 in an annular shape, wherein the guide groove 31 and the limit groove 32 are both arranged in an arc track with a certain angle around the center line of the movable sleeve 2 1 (such as Figure 4 As shown). The guide groove 31 and the limit groove 32 are internally connected, and the end of the movable sleeve 2 1 corresponding to the movable sleeve 1 3 is provided with a plug rod 13 in a ring shape. The longitudinal section of the plug rod 13 is "L" shaped, and the number of the plug rod 13 and the guide groove 31 are equal. The width of the plug rod 13 is equal to the width of the guide groove 31. The plug rod 13 is movably plugged into the inside of the guide groove 31 and the limit groove 32. After the movable sleeve 1 3 is rotated so that the plug rod 13 slides from the limit groove 31 to the inside of the guide groove 32, the movable sleeve 1 3 can be pulled out to separate the movable sleeve 1 3 and the movable sleeve 2 1. Separating the movable sleeve 1 3 from the movable sleeve 2 1 can facilitate the rotation of the adjusting screw 11, thereby realizing that the milling cutter 2 is extended from the inside of the movable sleeve 1 3, so that the milling cutter 2 can be fully utilized.

[0027] Furthermore, the bottom surface of the limiting groove 32 is provided with a second screw hole 33, the plug rod 13 is provided with a first screw hole 14, and bolts are threadedly connected inside the first screw hole 14 and the second screw hole 33. By providing the first screw hole 14 and the second screw hole 33, it is convenient to further strengthen the connection between the movable sleeve 1 3 and the movable sleeve 2 1, and further ensure the stability of the milling cutter 2.

[0028] Working principle: After the milling cutter 2 is worn, this type of carbide woodworking milling cutter can separate the movable sleeve 1 3 and the movable sleeve 2 1, and then rotate the adjusting screw 11. After rotating the adjusting screw 11, the position of the milling cutter 2 is limited by the guide rod 12. At this time, the milling cutter 2 will not rotate with the adjusting screw 11, and during the rotation of the adjusting screw 11, the milling cutter 2 can move in a square along the axis of the adjusting screw 11. Then, after the milling cutter 2 is worn, the milling cutter 2 can be moved out of the movable sleeve 1 3 to facilitate the use of the milling cutter 2; and for the separation of the movable sleeve 1 3 and the movable sleeve 2 1 mentioned above, it is only necessary to remove the bolts used to connect the movable sleeve 1 and the movable sleeve 2 3, and rotate the movable sleeve 2 1 so that the connecting rod 13 slides from the limiting groove 31 to the inside of the guide groove 32, and then the movable sleeve 1 3 is pulled out to separate the movable sleeve 1 3 and the movable sleeve 2 1.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
