[0037] like Figure 1-Figure 5 As shown, a profile cutting machine head disclosed in the present invention may include: a fixed frame 1, a rotating assembly, a limiting assembly, a clamping assembly, a protective assembly and other components.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, in the present disclosure, the rotating assembly includes a rotating rod 7, the rotating rod 7 is rotatably arranged on the inner side of the fixed frame 1, the fixed bracket 6 is fixedly connected to the outer side of the rotating rod 7, and the outer side of the rotating rod 7 is provided with a torsion spring 5;

[0039] The limiting assembly includes a first limiting groove 61 and a second limiting groove 62, and the first limiting groove 61 and the second limiting groove 62 are both arranged on the outer side of the fixing bracket 6;

[0040] The clamping assembly includes a limiting ring 83 , and the limiting ring 83 is disposed corresponding to the first limiting groove 61 and the second limiting groove 62 .

[0041] Thus, the fixed frame 1 is fixed on the base of the cutting machine, the rotating rod 7 is rotatably arranged on the inner side of the fixed frame 1, and the fixed bracket 6 is fixedly connected to the top of the rotating rod 7, so that the fixed bracket 6 can effectively rotate with the rotating rod 7, and the torsion spring 5 is arranged on the outer side of the rotating rod 7. The torsion spring 5 can effectively provide a torsion force to drive the rotating rod 7 to rotate, so as to drive the rotating rod 7 to rotate. Figure 2 As shown, from left to right, the torsion spring 5 can exert a counterclockwise torque on the rotating rod 7, driving the rotating rod 7 to rotate, so that the entire machine head is lifted. By setting the first limit groove 61 and the second limit groove 62, the limit ring 83 can be set at the second limit groove 62 to clamp the second limit groove 62, thereby preventing the fixed bracket 6 from continuing to rotate counterclockwise. Similarly, when the machine head needs to be used, the second limit groove 62 is removed, and then the fixed bracket 6 is rotated to make the fixed bracket 6 rotate clockwise, which facilitates the use of the fixed bracket 6. The setting of the first limit groove 61, the second limit groove 62 and the limit ring 83 can effectively limit the fixed bracket 6, and it can be quickly pulled out for use.

[0042] like Figure 4 As shown, in a preferred embodiment, a fixing sleeve 8 is fixedly connected to the outer side of the fixing frame 1, and the inner side of the fixing sleeve 8 is slidably connected to a sliding rod 81. A retaining ring 84 is provided on the outer side of the sliding rod 81, a pull rod 82 is fixedly connected to one end of the sliding rod 81, and a limiting ring 83 is provided at the other end of the sliding rod 81.

[0043] Therefore, by setting the fixing sleeve 8, the fixing sleeve 8 is fixed on the outside of the fixing frame 1, and the sliding rod 81 can slide on the inside of the fixing sleeve 8. The setting of the pull rod 82 can effectively drive the sliding rod 81 to move, so that the pull rod 82 is pulled from the outside to drive the sliding rod 81 to move. By fixing the limiting ring 83 with the sliding rod 81, the sliding rod 81 can drive the limiting ring 83 to move. The snap ring 84 is symmetrically arranged at both ends of the inner side of the sliding rod 81. When the sliding rod 81 moves on the inner side of the fixing sleeve 8, the snap ring 84 can effectively limit the moving position of the fixing sleeve 8, so that the sliding rod 81 cannot slide out from the inner side of the fixing sleeve 8.

[0044] like Figure 1 As shown, in the present disclosure, a cutting blade 3 is arranged above the fixed frame 1, and a protective component is arranged on the outside of the cutting blade 3. The protective component includes an arc-shaped movable plate 2 and a protective shell 4. The arc-shaped movable plate 2 is rotatably arranged on the outside of the protective shell 4.

[0045] Therefore, a rack for fixing the motor is provided above the fixed bracket 6, and the cutting blade 3 is fixedly connected to the output shaft of the motor, thereby driving the cutting blade 3 to rotate. The arc-shaped movable plate 2 and the protective shell 4 are both provided on the outside of the cutting blade 3 to protect the cutting of the cutting blade 3. The arc-shaped movable plate 2 can rotate and rotate on the outside of the cutting blade 3, so as to facilitate the adjustment of the exposed area of ​​the cutting blade 3 and facilitate the subsequent cutting work.

[0046] like Figure 1 As shown, in a preferred embodiment, the end of the arc-shaped moving plate 2 is fixedly connected to a connecting plate 22 , and the other end of the connecting plate 22 is fixedly connected to a rotating disk 21 .

[0047] Therefore, by setting the connecting plate 22 and the rotating disk 21, the arc-shaped movable plate 2 is fixed to the rotating disk 21 through the connecting plate 22. The arc-shaped movable plate 2 is set in an arc shape, and both sides are fixed to the rotating disk 21 through the connecting plate 22. By setting the connecting plate 22, the connecting plate 22 is set in an italic shape, which can effectively increase its overall usage strength.

[0048] like Figure 1 and Figure 5 As shown, in the present disclosure, a shift block 23 is provided on the outer side of the arc-shaped movable plate 2, and a first limit block 24 and a second limit block 25 are respectively provided at both ends of the inner side of the arc-shaped movable plate 2, and a limit bolt 41 is provided at the top end of the protective shell 4, and the first limit block 24 and the second limit block 25 are provided corresponding to the limit bolt 41.

[0049] Therefore, by setting the shift block 23, the shift block 23 can effectively drive the arc-shaped movable plate 2 to rotate on the outside of the protective shell 4. By setting the first limit block 24 and the second limit block 25, it can be effectively used in conjunction with the limit bolt 41. During specific use, when the arc-shaped movable plate 2 needs to be set on the outside of the cutting blade 3 for protection, the first limit block 24 is set on the outside of the limit bolt 41, and the limit bolt 41 limits the first limit block 24 to prevent the arc-shaped movable plate 2 from continuing to rotate downward. When the cutting blade 3 needs to be exposed more for use, the shift block 23 is driven to rotate the arc-shaped movable plate 2, so that the second limit block 25 is set on the other side of the limit bolt 41, and the position of the arc-shaped movable plate 2 is limited, so that the entire arc-shaped movable plate 2 is set on the outside of the protective shell 4.
