Because such spacers can only clamp one cable at a time, in actual operation, a worker needs to operate a plurality of spacers at high altitude, for example, six spacers of six spacer arms 6 need to be operated respectively six times, and the operation is complicated and the efficiency is low.

When the spacer rod is used for clamping cables (preferably six cables), after the cables are sleeved in the first clamping part 8, all the movable buckling pieces 10 can be moved by rotating one movable ring 3, and all the cables are clamped through the movable buckling pieces 10 and the fixed buckling pieces 7, so that the installation convenience is improved, and the installation efficiency is improved.

when the cable passes over the unidirectional element 22 and is clamped into the second clamping part 11, the unidirectional element 22 at the moment rebounds under the elastic force of the reset torsion spring 23, and the outer side of the unidirectional element 22 is enabled to be abutted against the stop inclined surface 24, the unidirectional element 22 at the moment is still inclined towards the cable, and the cable can be prevented from being separated from the fixed buckling element 7, wherein the unidirectional element 22 only has the function of limiting the cable for a plurality of times or a plurality of time periods when in actual use, so that the unidirectional element 22 has lower requirements on strength and service life.

Moreover, because the free end of the fixing buckle 7 is lengthened by the anti-falling arm 20, the anti-falling arm 20 can also play a guiding role when the cable is clamped into the first clamping part 8, so that the cable is conveniently clamped into the first clamping part 8. Meanwhile, the anti-falling arm 20 lengthens the length of the fixed buckling piece 7, and meanwhile, the anti-falling arm 20 is inclined downwards, so that the cable on the top can be further prevented from falling out of the fixed buckling piece 7 (before the cable is clamped).

After the positions of the two cables on the top are stable, the rest of the anti-falling arms 20 are inclined upwards, so that other cables can be conveniently clamped into the corresponding first clamping parts 8, in the actual operation, the bottom of a worker steps on the two cables at the bottom, so that the two anti-falling arms 20 at the bottom can be stably buckled with the two cables at the bottom, and the two cables at the two sides can play a limiting role through the unidirectional piece 22 because no other acting force is applied to the two cables at the two sides.

When all cables are clamped in the corresponding first clamping parts 8, a worker rotates the adjusting parts 40 by using tools such as a wrench, the adjusting parts 40 drive the adjusting screw 39 to rotate, the adjusting screw 39 and the first adjusting seat 37 are relatively fixed and only rotate relatively, the adjusting screw 39 pulls the linkage piece 43 to move towards the first adjusting seat 37 in the rotating process, meanwhile, the linkage piece 43 approaches the first adjusting seat 37 through the second adjusting seat 38 through the linkage arm 44, so that the movable ring 3 rotates relative to the fixed ring 1, and in the rotating process, the sliding piece 9 is driven to move towards the fixed buckling piece 7 through the hinge arm 12 until the sliding piece 9 and the hinge arm 12 are in the same straight line. Wherein the first clamping part 8, the second clamping part 11 and the third clamping part 19 are all in an interference fit with the cable when clamping the cable.

When the cable is clamped, the first positioning hole 25 is communicated with the second positioning hole 26, at this time, the worker passes the auxiliary bolt 27 through the first positioning hole 25 and the second positioning hole 26, the anti-falling bar 36 is driven by the inner walls of the first positioning hole 25 and the second positioning hole 26 in the passing process, and is clamped into the yielding groove 35 after being elastically deformed, and the auxiliary bolt 27 can pass through the first positioning hole 25 and the second positioning hole 26.

In the process of moving the auxiliary bolt 27, the anti-falling ring 33 firstly enters the anti-rotation groove 31, and meanwhile, the anti-falling protrusion 34 enters the clamping groove 32, until the anti-falling ring 33 is abutted against the fixed ring 1, the anti-falling protrusion 34 is rotated, so that the anti-falling protrusion 34 is clamped into the bending part at the tail end of the clamping groove 32, and meanwhile, the auxiliary nut 28 is also attached to the inner wall of the anti-rotation groove 31;

Then, the worker connects the auxiliary nut 29 to the free end of the auxiliary bolt 27 by screw, and in the process of rotating the auxiliary nut 29, the auxiliary bolt 27 is prevented from coming out of the first positioning hole 25 and the second positioning hole 26 because the inner wall of the bent portion of the engagement groove 32 plays a role in limiting the drop-preventing protrusion 34, and at the same time, the auxiliary bolt 27 cannot be rotated because the rotation-preventing groove 31 can play a role in limiting the auxiliary nut 28, i.e., the auxiliary bolt 27 cannot move outwards and cannot rotate at the same time, so that the connection of the auxiliary nut 29 is simple and convenient, and a tool such as a wrench is not required to be used for maintaining the position of the auxiliary nut 28.

Moreover, the auxiliary nut 29 can press the anti-falling bar 36 downwards firstly in the moving process, and the anti-falling bar 36 enters the yielding groove 35, when the auxiliary nut 29 and the auxiliary nut 28 clamp the fixed ring 1 and the guide ring, the auxiliary nut 29 just passes over the free end of the anti-falling bar 36, and the free end of the anti-falling bar 36 pops outwards and is propped against the outer side of the auxiliary nut 29, or plays a limiting role on the outer side of the auxiliary nut 29, so that the position of the auxiliary bolt 27 is ensured, meanwhile, the stability of the holding position between the fixed ring 1 and the movable ring 3 can be ensured, the strength of the fixed ring 1 and the movable ring 3 can be improved, and the service life of the spacer is ensured.

When the cable is clamped, the third clamping portion 19 is opposite to the second clamping portion 11, that is, the second clamping portion 11 acts on the inner side of the cable, and the first clamping portion 8 and the third clamping portion 19 act on the outer side of the cable, so that not only can the connection stability of the spacer and the cable be improved, but also the movable fastening member 10 can be better prevented from being subjected to lateral torsion, and meanwhile, the spacer arm 6 can be prevented from being subjected to lateral torsion (the anti-falling portion 16 is fastened in the anti-falling groove 13, and if the movable fastening member 10 is subjected to lateral stress, the anti-falling portion 16 can apply lateral acting force to the inner wall of the anti-falling groove 13), and the service life of the spacer arm 6 is guaranteed.

The cross section formed by the connecting part 15 and the anti-falling part 16 and the cross section formed by the anti-falling groove 13 and the movable groove 14 are T-shaped, so that the sliding piece 9 can stably slide along the length direction of the spacing arm 6. At the same time, both sides of the outer end of the articulated arm 12 are articulated by the anti-drop portion 16 and the extension portion 17, respectively, thus ensuring the positional stability of the articulated arm 12 and the stability of the driving of the slider 9.
