The locking part 3 includes a connecting strap 31, one end of which is rotatably connected to the fixing base 1 via a pin, and the other end is connected to a locking strap 32. The fixing base 1 has a locking channel 11 for inserting and locking the locking strap 32. The locking strap 32 has ratchet teeth 321, and the locking channel 11 has locking teeth 21. The locking strap 32 engages with the locking teeth 21, preventing it from being pulled out of the locking channel 11. Through the engagement of the ratchet teeth 321 and the locking teeth 21, the locking strap 32 can be securely locked within the locking channel 11, preventing accidental detachment or loosening during use and ensuring the stability of the cable fixing. The locking structure, with the ratchet 321 and locking tooth 21 working together, can withstand greater tension or load, is not easily damaged or degraded, effectively prevents loosening caused by external force or vibration during cable fixing, and extends the service life of the product.
[0023] The locking teeth 21 are located at the front end of the locking block 2, which is rotatably positioned within the locking channel 11 via a torsion spring. Positioning the locking teeth 21 at the front end of the locking block 2 effectively ensures precise engagement between the locking teeth 21 and the ratchet teeth 321 on the locking band 32. The rotating design of the locking block 2 allows it to flexibly enter and exit the locked state, quickly locking or unlocking the cable when needed, providing greater operational convenience while ensuring a secure lock.
[0024] The rear side of the locking block 2 is provided with a pressing block 22, which is in a circular arc concave shape. The fixed seat 1 is provided with a pressing groove 12 matched with the pressing block 22. The locking block 2 is unlocked from the locking band 32 by pressing the pressing block 22 to lift the locking block 2. The design of the pressing block 22 makes the unlocking process of the locking block 2 and the locking band 32 more convenient.

The two sides of the first fixed sheet 4 are provided with first connecting grooves 41, and the second fixed sheet 5 is provided with second connecting grooves 51. The first connecting grooves 41 and the second connecting grooves 51 are connected to form a I-shaped groove, and the first fixed sheet 4 and the second fixed sheet 5 are installed in the I-shaped groove through the I-shaped connecting sheet 6 to form a clamping connection. Through the detachable connection design of the first fixed sheet 4 and the second fixed sheet 5, the user can conveniently replace or adjust the identification tag. The I-shaped structure design enhances the fixing effect of the label, ensures that the label will not easily fall off during operation, and provides higher firmness. Different information or numbers can be marked as needed, which is convenient for identifying and managing the cable fixing fitting.
[0028] The first connecting groove 41 is provided with a first fixing hole 42, the second connecting groove 51 is provided with a second fixing hole 52, the connecting piece 6 is provided with a third fixing hole 61 corresponding to the first fixing hole 42 and the second fixing hole 52 respectively, and the connecting piece 6 is fixedly connected with the first fixing piece 4 and the second fixing piece 5 by inserting the fixing column 7 into the two third fixing holes 61. By arranging the fixing holes in the first connecting groove 41 and the second connecting groove 51 and using the fixing column 7 to connect the connecting piece 6 with the fixing piece, the connection between the identification tag and the fixing seat 1 is more firm. By the insertion mode of the fixing column 7, the user can quickly and simply install the connecting piece 6 between the first fixing piece 4 and the second fixing piece 5.
[0029] The other end of the fixing column 7 extends into the first fixing hole 42 and the second fixing hole 52 respectively to form a tight fit connection. The risk of loosening or falling off is avoided, and the stability of the connection is improved. Although the tight fit connection provides high strength fixation, a certain detachability is still reserved. When disassembly or replacement is needed, the user can easily take out the fixing column 7 from the fixing hole without using complex tools or equipment, simplifying the maintenance process.
[0030] The above disclosed is only the preferred embodiment of the utility model, of course, cannot with this to limit the utility model right range, therefore according to the utility model claim is made equivalent change, still belongs to the range that the utility model covers.
[0031] Although the utility model has been described with reference to several specific embodiments, it should be understood that the utility model is not limited to the disclosed specific embodiments. The utility model is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
