A protective cover 30 is arranged outside the blade 20, a fixed seat 31 is arranged on one side of the protective cover 30 facing the angle adjusting device 120, and the angle adjusting device 120 is connected with the fixed seat 31 in a matching mode. One side of the angle adjusting device 120 is connected to the fixing base 31, the other side is attached to the adjusting plate 130, and the adjusting plate 130 is installed on the bottom plate 110. The angle adjusting device 120 is respectively provided with a first adjusting hole 123 and a second adjusting hole 125, and the first adjusting piece 124 is installed in the first adjusting hole 123 and can rotate in the first adjusting hole 123; the second adjustment member 126 is installed in the second adjustment hole 125 and can rotate in the second adjustment hole 125, and the second adjustment hole 125 is provided with an extension member 127. Therefore, the angle adjusting means 120 is adjusted so that the positioning surface 111 is parallel to the workpiece, and thus the blade 20 is parallel to the workpiece, according to the actual offset between the mounting position of the blade 20 and the workpiece. The blade 20 can cut the workpiece linearly in the direction of the positioning surface 111.

When the first adjusting member 124 rotates clockwise in the first adjusting hole 123, the first adjusting member 124 applies pressure to the angle adjusting device 120, the first adjusting member 124 moves toward the direction close to the fixing seat 31, when the first adjusting member 124 is close to the fixing seat 31, the first adjusting member 124 cannot move into the fixing seat 31 any more, and then the first adjusting member 124 continues to rotate clockwise, the fixing seat 31 will react on the angle adjusting device 120, so that the angle adjusting device 120 moves toward the direction away from the fixing seat 31, that is, the angle adjusting device 120 moves toward the direction away from the blade 20, the angle adjusting device 120 drives the adjusting plate 130 to move, the adjusting plate 30 drives the bottom plate 110 to move, and the positioning surface 111 moves toward the direction close to the blade 20.

When the second adjusting member 126 rotates clockwise in the second adjusting hole 125, the second adjusting member 126 applies pressure to the angle adjusting device 120, the extending member 127 on the second adjusting hole 125 fixes the angle adjusting device 120, the extending member 127 passes through the fourth through hole 314, the extending member 127 is fixed on the fixed seat 31, the second adjusting member 126 passes through the fixed seat 31, so that the angle adjusting device 120 can move towards the direction close to the fixed seat 31 continuously, that is, the angle adjusting device 120 moves towards the direction close to the blade 20, the angle adjusting device 120 drives the adjusting plate 130 to move, the adjusting plate 30 drives the bottom plate 110 to move, and the positioning surface 111 moves towards the direction far away from the blade 20.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
