[0026] Several fixing mechanisms are connected in sequence through several connecting blocks 3 to form a harness installation assembly for fixing the cable harness;

[0027] The two connecting parts of each connecting block 3 are respectively adapted and fixed to the slots 11 of the fixing mechanisms on both sides, and the second screw hole 31 on one side of each connecting part and the first screw hole 12 above the corresponding slot 11 form a channel for the rod of the fixing bolt to pass through; after the rod of the fixing bolt passes through the channel, the bottom of the fixing bolt is fixed to the mounting surface.

[0028] The specific implementation process of this embodiment includes:

[0029] In this embodiment, slots 11 are provided on both sides of the base 1 of the fixing mechanism so as to facilitate the fixing with the connecting block 3. Several fixing mechanisms are fixed by several connecting blocks 3 to form a harness installation assembly for fixing the cable harness. When installing the cable harness, the cables of the cable harness are fixed to the corresponding fixing mechanisms respectively, so that the cable harness is more neat during installation; at the same time, the harness installation assembly is fixed to the installation surface by multiple fixing bolts, so that the cable harness is more firmly installed. The technical problem that the inconvenient fixing during the installation of the cable harness affects the work efficiency in the prior art is solved.

[0030] In this embodiment, a guide portion 32 is provided at the opening of each second screw hole 31 on the top of the connection block 3, and a transition portion adapted to the guide portion 32 is provided at the top of the card slot 11 of the base 1 at the first screw hole 12;

[0031] The guide portion 32 cooperates with the transition portion to connect the second screw hole 31 with the first screw hole 12 .

[0032] In this embodiment, when the base 1 is installed on the connection block 3, the slot 11 is placed above the connection part of the connection block 3, and the transition part is aligned with the guide part 32; then the base 1 is pressed downward so that the connection part completely enters the slot 11 and the guide part 32 and the transition part are completely adapted; further, the first screw hole 12 and the second screw hole 31 are connected.

In this embodiment, the elastic snap ring 22 includes a circular ring with a notch; during installation, the cable can pass through the side of the elastic snap ring 22 or enter through the notch. Figure 1 As shown, in this embodiment, the size of the elastic snap ring 22 corresponding to the fixing unit 2 of each fixing mechanism can be different; in this embodiment, the size of the elastic snap ring 22 is related to the cable size; the larger the cable size, the larger the size of the elastic snap ring 22.

[0040] In some embodiments, the size of the elastic clip 22 is related to the size of the sub-cable harness. The larger the size of the sub-cable harness, the larger the size of the elastic clip 22 .

[0041] In this embodiment, the fixing unit 2 further includes:

[0042] The locking bolt 21 and the elastic snap ring 22 are both provided with mounting parts on both sides of the gap, and each mounting part is provided with a through hole; the rod of the locking bolt 21 passes through the through holes of the two mounting parts in sequence to close the gap of the elastic snap ring 22.
