As shown in fig. 5, the first driving motor 151 and the second driving motor 161 respectively drive the driving disc 12 and the mounting disc 13 to rotate in the same direction at the predetermined speed. In this state, the rotation speeds of the driving disc 12 and the mounting disc 13 are the same, and the predetermined speed is a preset cutting and peeling rotation speed in the control mechanism and is set according to different cable materials to be processed. The position of the sliding block 149 relative to the driving disc 12 and the mounting disc 13 is unchanged, and the sliding block is positioned at one end of the arc-shaped groove 125 away from the axle center; the first connecting arm 145 and the second connecting arm 147 are located on the sliding groove 135, and the relative positions are unchanged; the tool bit 141 is also moved at the rotational speed along with the driving disk 12 and the mounting disk 13 in a state to be machined.

The tool bit 141 is in a working state. As shown in fig. 6, a position at a certain point in this state is schematically shown. The rotation speed of the driving disc 12 is greater than that of the mounting disc 13, one end of the slider 149 slides along the arc-shaped slot 125 to the other end, and at the same time, the other end of the slider 149 moves along the sliding hole 137 near the axle center and drives the first connecting arm 145 and the second connecting arm 147 to slide along the sliding slot 135 toward the axle center, and the positions of the slider 149, the first connecting arm 145 and the second connecting arm 147 relative to the driving disc 12 and the mounting disc 13 change, and finally, the slider 149, the first connecting arm 145 and the second connecting arm 147 are positioned near one end of the arc-shaped slot 125 near the axle center. Of course, according to the different sizes of the cables to be processed, the control mechanism controls the relative position of the slider 149 by controlling the first driving mechanism 15 and the second driving mechanism 16, thereby controlling the position of the cutter head 141. I.e. the position of the slider 149 is not necessarily in the second state, but the final stripping range is determined according to the size of the cable to be processed, thereby determining the position of the slider 149 with respect to the arc-shaped slot 125 and the slide hole 137.

The cutter assembly 14 rotates with the drive disk 12 and the mounting disk 13, with the slider 149 position unchanged.
The first driving mechanism 15 and the second driving mechanism 16 are controlled by the control mechanism, and the transmission speeds of the first driving mechanism 15 and the second driving mechanism 16 are changed according to the preset speed setting, when the rotation speed of the driving disc 12 is greater than that of the mounting disc 13, one end of the slider 149 slides along the arc-shaped groove 125 toward the axial direction, and the other end moves along the sliding hole 137 toward the axial direction, and drives the first connecting arm 145 and the second connecting arm 147 to slide along the sliding groove 135. The tool bit 141 approaches the axis under the combined action of the first connecting arm 145, the second connecting arm 147 and the fixing member 143, that is, the tool bit 141 gradually approaches the cable to be processed while performing the rotation motion, and performs the rotary cutting.
After the cutter head 141 reaches the machining depth, the transmission speed is changed again by the preset speed in the control mechanism, the rotation speed of the driving disc 12 is smaller than that of the mounting disc 13, one end of the slider 149 is rapidly far away from the axle center along the arc-shaped groove 125, the other end of the slider 149 is far away from the axle center along the sliding hole 137, and simultaneously the first connecting arm 145 and the second connecting arm 147 are driven to slide along the sliding groove 135, and the cutter head 141 is far away from the machined cable.
When the slider 149 returns to the initial position, the rotational speed of the drive disk 12 is equal to the rotational speed of the mounting disk 13, the cutter assembly 14 returns to the ready-to-process state, the finished cable is removed, and the above steps are repeated.
The predetermined speed includes two parameter variations, namely, parameter control of the first driving mechanism 15 (parameter one) and the second driving mechanism 16 (parameter two), and is subjected to four links of processing, and is cycled back and forth. The first parameter is consistent with the second parameter in the stage of the link to be processed; the cutting and peeling stage is carried out, wherein the first parameter is gradually larger than the second parameter; the cutting and peeling stage is completed and the parameter I is gradually reduced relative to the parameter II until the parameter I is the same as the parameter II and is started to be smaller than the parameter II; when the slider 149 is gradually returned to the initial position and finally returned to the stage to be machined, the first parameter is gradually increased relative to the second parameter until the same.
