[0031] During actual use, the electric cylinder 13 is first started, and the electric cylinder 13 drives the pressure block 51 to rise, and the cable harness is passed between the die 1 61 and the die 2 62. The electric cylinder 13 is reversed and started, and the electric cylinder 13 drives the die 1 61 to descend through the pressure block 51, so that the die 1 61 and the die 2 62 are fitted together, and the threaded ring 7 is turned. The threaded ring 7 slides on the die 1 61 and the die 2 62, and the sliding process pushes multiple sliders 67 to approach each other to restrain the cable harness.
