The fixing sleeve 201 has a cavity 202 inside, and the main connecting sleeve 1 is located in the cavity 202. An extension rod 301 and an extension sleeve 302 are fixedly connected to the lower end face of the connecting block 3. The extension rod 301 and the extension sleeve 302 are inserted into the cavity 202, and the main connecting sleeve 1 is inserted into the cavity 202 formed between the extension rod 301 and the extension sleeve 302. The connecting block 3 can adjust the length of the extension rod 301 and the extension sleeve 302 in the cavity 202 by sliding the extension rod 301 and the extension sleeve 302 in the cavity 202, so as to adjust the extension length of the connecting block 3 and the extension length of the wire clamp 4 fixedly connected to the upper end face of the connecting block 3, thereby adjusting the splitting distance of the spacer bar.

[0035] In this embodiment, multiple threaded holes 303 are opened on the outer side of the extension sleeve 302, and a sliding groove 203 is opened on the outer side of the fixing sleeve 201. The position of the threaded holes 303 corresponds to the sliding groove 203. A fixing bolt 7 is slidably connected in the sliding groove 203. An arc plate 701 is fixedly connected to the outer side of the middle part of the fixing bolt 7. The sliding groove 203 is engaged between the arc plate 701 and the top of the fixing bolt 7 to prevent the fixing bolt 7 from disengaging from the sliding groove 203. The threaded part 702 at the bottom of the fixing bolt 7 is connected to the threaded hole 303 to fix the extension rod 301 and the extension sleeve 302. The arc plate 701 will descend so that the arc surface of the lower end of the arc plate 701 presses against the extension sleeve 302, so that the extension sleeve 302 presses against the main connecting sleeve 1 to prevent the wire clamp 4 from shaking, thereby fixing the connecting block 3 and the wire clamp 4. The arc plate 701 can also prevent the wire from dancing and protect the wire.

[0036] When the spacing of the spacers needs to be adjusted, tighten the fixing bolt 7 to disengage the threaded part 702 from the threaded hole 303, and the arc plate 701 rises to release the restriction on the extension sleeve 302. The extension distance of the extension sleeve 302 and the extension rod 301 can then be adjusted as needed.

[0039] Specifically, the bottom of the fixing bolt 7 is fixedly connected to a threaded part 702, and the threaded part 702 is bolted to the threaded hole 303 on the extension sleeve 302.

[0040] Specifically, the arc-shaped plate 701 is disposed between the extension sleeve 302 and the fixed sleeve 201. When the fixing bolt 7 is released from the threaded hole 303, the arc-shaped plate 701 can move up and down in the cavity 202 between the extension sleeve 302 and the fixed sleeve 201.

[0041] Specifically, rubber pads 5 are fixedly connected to the inner sides of both the upper and lower clamps of the wire clamp 4.

The extension rod 301 and the extension sleeve 302 are inserted into the cavity 202, and the main connecting sleeve 1 is inserted into the cavity 202 formed between the extension rod 301 and the extension sleeve 302. The connecting block 3 can adjust the length of the extension rod 301 and the extension sleeve 302 within the cavity 202 by sliding them, thereby adjusting the extension length of the connecting block 3. This adjusts the extension length of the wire clamp 4 fixedly connected to the upper end face of the connecting block 3, thus adjusting the splitting distance of the spacer bar and extending the... Multiple threaded holes 303 are opened on the outer side of sleeve 302. A sliding groove 203 is opened on the outer side of fixed sleeve 201. The position of threaded holes 303 corresponds to sliding groove 203. Fixed bolt 7 is slidably connected in sliding groove 203. An arc plate 701 is fixedly connected to the outer side of the middle part of fixed bolt 7.
