8. A cable cutting apparatus according to claim 7, wherein: the second auxiliary gear (402) is connected above the second main gear (400) in a riveting mode through a bolt, the transmission main arm rod (403) is connected to the side face of the second auxiliary gear (402) in a threaded engagement mode, and the transmission support arm rod (404) is connected between the transmission main arm rod (403) and the manipulator transmission device (41) in a riveting mode through a bolt.

9. A cable cutting method is characterized in that initially, a cable just passes through a cable hole, the centers of the cable hole and a wire outlet pipe (324) are on the same straight line, a clamping door is in an open state, and the specific cutting steps are as follows:

step S1: a user pulls down the hand-pulling main switch (200) first, the pull wire (203) is pulled to drive the balance support rod (205) to lose balance, so that the electrified small ball (207) is connected with the reverse circuit touch block (208), the power supply module is turned on, and the PLC, the first motor (30) and the second gear set (40) are electrified;

step S3: the PLC controller controls the cable rotating shaft (322) to rotate, and the cable can enter the wire outlet pipe (324) which is on the same straight line with the center of the wire hole along the wire hole as the cable is a hard wire; when the rotating shaft rotates (322), the length detection sensor detects the length of the cable sent out by the rotating shaft, and when the length reaches a set value, the PLC controls the rotating shaft of the cable to stop rotating;

step S5: the tension detector detects the tension of the cable in the wire hole at the moment, and the tension is certainly smaller than a set value due to looseness of the cable which is just sent in, so that the cutting effect is influenced, at the moment, the PLC controls the first motor (30) to rotate positively, the first main gear (310) drives the first auxiliary gear (312) to rotate, so that the gear transmission supporting rod (313) is driven to rotate, the traction supporting rod (315) is pushed to move horizontally, the traction connecting rod (316) is connected with the transmission bracket (32), and the transmission bracket (32) is pushed to work; when the traction connecting rod (316) drives the threading plate (321) to horizontally move on the guide rail groove (320), the cable is stretched, so that the tension of the cable is increased;

step S6: when the tension detector detects that the tension of the cable reaches a set value, the PLC controller controls the first motor (30) to stop rotating;

step S7: the PLC controller controls the second motor (42) to rotate positively, the second main gear (400) drives the second auxiliary gear (402) to rotate, and simultaneously drives the transmission main arm rod (403) and the transmission support arm rod (404) to move, so that the transmission small sliding block (411) is pushed to move horizontally, and the mechanical arm transmission device (41) works; when the small transmission sliding block (411) moves horizontally, the transmission push rod (412) is pushed to move, so that the transmission telescopic support rod (413) is pushed to move towards the cutting blade (417), meanwhile, the adjusting support rod (415) is folded under the pushing action of pushing the transmission telescopic support rod (413), so that the blade fixing seat (416) is closed, and the cutting blade (417) is closed to perform cutting work.

10. The cable trimming method according to claim 9, wherein the step of returning to the initial state is performed after the trimming step is completed, and the specific steps are as follows:

step K1: after cutting, the PLC controls the first motor (30) to reversely rotate to the initial state, so that the threading plate (321) returns to the original position, and the centers of the thread hole and the thread outlet pipe (324) are still in the same straight line; at the same time, the PLC controller controls the second motor to reversely rotate back to the initial state, and the cutting blade (417) is restored to the opening state.
