As shown in fig. 1, in a first aspect, there is provided a cutter structure 1 for use in a sports car assembly 2, comprising:

the cutting tool comprises a first driving assembly 11 and a cutting tool 12, wherein the first driving assembly 11 can drive the cutting tool 12 to rotate relative to the first driving assembly 11.

It should be noted that the first driving assembly 11 of the above-mentioned cutter structure 1 is integrated with the cutter 12, and is applied to the sports car assembly 2. The sports car assembly 2 is an assembly for controlling the feed or the retraction of the cutter structure 1 in the cutting machine. In this application, a sports car structure comprises a cutter structure 1 for cutting and a sports car assembly 2 for advancing/retracting the cutter. In addition, the first drive assembly 11 of the present application is preferably a servomotor.

In the prior art cutting machine carriage assembly 2, two motors are included therein, one for driving the cutter 12 to advance/retract and one for driving the cutter 12 to rotate, so as to change the cutting angle. It should be noted that, in the prior art, the two motors are both disposed inside the sports car, and when the motor for driving the cutter 12 to rotate fails, the transmission structure connected to the motor and the cutter 12 disposed outside the sports car assembly 2 need to be disassembled first, then the cutting machine and the sports car assembly 2 need to be disassembled, the motor needs to be replaced, then the sports car assembly 2 and the cutting machine need to be assembled, and finally the transmission structure and the cutter 12 need to be connected to the motor.
