[0012] The utility model is further described below in conjunction with the accompanying drawings:

[0013] Example:

[0014] As attached Figure 1 and attached Figure 2 As shown, the utility model provides a new type of cutting machine head, including a driving motor 1, a head base 2 is installed on the lower output shaft of the driving motor 1, and is characterized in that a convenient-to-disassemble cutting head structure 3 is installed at the lower part of the head base 2; positioning grooves 4 are respectively provided on the left and right sides of the head base 2; the convenient-to-disassemble cutting head structure 3 includes a rectangular plug-in block 31, and a cutting machine head 32 is welded to the lower part of the rectangular plug-in block 31; a positioning frame 33 is welded to the middle position of the rectangular plug-in block 31; transverse slots 34 are respectively provided on the front and rear sides of the positioning frame 33; positioning blocks 35 are respectively plugged into the left and right sides of the positioning frame 33; A return spring 36 is provided in the middle position inside the positioning frame 33; the front and rear ends of the positioning block 35 close to the return spring 36 are respectively welded with limit blocks 37, and the limit blocks 37 are inserted into the inner side of the transverse groove 34. The return spring 36 is used to facilitate the positioning block 35 to be pushed into the inner side of the positioning groove 4, and then to facilitate the rectangular plug-in block 31 to be fixed to the inner side of the head seat 2. On the contrary, when the positioning block 35 is pressed into the positioning block 35 in the positioning groove 4, it is convenient to remove the rectangular plug-in block 31 from the head seat 2, and the limit blocks 37 can prevent the positioning block 35 from being pushed out from the positioning frame 33 under the action of the return spring 36.
