[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. It can fit the corresponding clamping sleeves onto the post according to the number of extra-long cables in the cable harness. Then, by rotating the threaded rod, multiple lugs are pressed against the inner walls of multiple clamping sleeves to assemble the clamping sleeves onto the post. Then, the extra-long part of each cable is fixed between the fixing seat and the fixing coil on each clamping sleeve to bind it. This can accommodate different numbers of extra-long cables and improve the flexibility of use.
[0014] 2. By rotating the fixing stud, the second guide block, which is pressed against the second guide groove, can be moved, allowing the cable holder to slide in the cable holder housing when the second guide block is no longer pressed against it. This adjusts the length between the cable holder housing and the cable holder to accommodate extra-long sections of cables of different lengths.
[0015] 3. When binding, place the excess cable portion at the end of the cable holder, then insert the lug on the cable holder into the socket and slot on the cable holder. During insertion, the locking block is pushed into the receiving cavity by the lug. At this time, the spring body contracts and deforms. When the lug is inserted to the bottom of the slot, the cable holder just covers the cable. Then, the spring body returns to its original shape and pushes out the locking block to lock into the slot on the lug, thus fixing the cable holder and the cable holder together. This fixes the cable to the end of the cable holder, completing the binding process. The process only requires pressing the cable holder to bind the excess cable portion, making it simple to operate and effectively improving ease of use. Attached Figure Description

[0034] During binding, according to the number of extra-long cables in the cable bundle 31, corresponding clamping sleeves 6 are fitted onto the post 1. Then, the threaded rod 12 is rotated to tighten multiple lugs 5 against the inner walls of multiple clamping sleeves 6, thus assembling the fitted clamping sleeves 6 onto the post 1. Then, the fixing stud 11 is rotated to move the second guide block 21, which is pressed against the second guide groove 20, allowing the cable holder 3 to slide in the cable holder 2 without the pressure of the second guide block 21. This adjusts the length between the cable holder 2 and the cable holder 3 on each clamping sleeve 6 to accommodate the length of the extra-long portion of each cable. Then, the extra-long portion of the cable is adjusted accordingly. The cable is placed at the end of the cable holder 3 on each clip sleeve 6. Then, the lug 18 on the cable holder 4 is inserted into the socket 17 and slot 16 on the cable holder 3. During the insertion process, the locking block 15 is pushed into the receiving cavity 30 by the lug 18. At this time, the spring body 29 contracts and deforms. When the lug 18 is inserted to the bottom of the slot 16, the cable holder 4 just presses on the cable. At this time, the spring body 29 returns to its original shape and pushes out the locking block 15 to lock into the slot 19 on the lug 18, so as to fix the cable holder 4 and the cable holder 3 together, that is, fix the cable to the end of the cable holder 3, so as to complete the binding of the extra-long part of the cable.
