The cutting knife 320 is arranged on the mounting seat 310, and the cutting knife 320 penetrates through the strip-shaped hole 220 along the radial direction of the cable head 600 and is used for cutting the cable head 600. Specifically, the position of the cutting knife 320 in the first direction OX corresponds to the indication position of the indication structure 210 in the first direction OX all the time, so that the cutting knife 320 can accurately cut at the indication position of the indication structure 210, and the cutting error caused by the difference between the cutting position and the indication position is prevented.

In this embodiment, the cutting mechanism 300 further includes an adjusting assembly 330, the adjusting assembly 330 is disposed on the mounting seat 310, the adjusting assembly 330 can be close to the cable head 600 or far from the cable head 600 along the radial direction of the cable head 600, the cutting knife 320 is mounted on the adjusting assembly 330, and the adjusting assembly 330 is used for adjusting the length of the cutting knife 320 passing through the strip-shaped hole 220, so as to change the cutting depth of the cutting knife 320.

In other embodiments, it is also possible that the sliding mechanism is an elastic sheet, so that during cutting, the cutting mechanism can be bent along the second direction OY, and then the cutting mechanism is moved along the second direction OY, so as to enable cutting of the outer sheath of the cable head.

In some embodiments, the adjustment assembly 330 includes an adjustment bolt 331, a connecting member 332, and an elastic member 333, the adjustment bolt 331 being threadedly coupled to the mounting base 310.

The adjusting bolt 331 is threadedly coupled to the mounting base 310, and in use, the adjusting bolt 331 is moved toward or away from the cable head 600 by rotating the adjusting bolt 331. For example, the adjusting bolt 331 is rotated clockwise, the adjusting bolt 331 moves downward to press the connecting member 332, and the elastic member 333 is compressed between the connecting member 332 and the sliding mechanism 200, i.e., the connecting member 332 drives the cutting blade 320 to move downward, so as to increase the length of the cutting blade 320 extending out of the strip-shaped hole 220, i.e., increase the cutting depth. The adjusting bolt 331 is rotated counterclockwise, the adjusting bolt 331 moves upward, the connecting member 332 moves upward under the elastic action of the elastic member 333, and the connecting member 332 drives the cutting knife 320 to move upward, so that the length of the cutting knife 320 extending out of the strip-shaped hole 220 is reduced, that is, the cutting depth is reduced.
