[0042] Through the cooperation of the fixing mechanism 400 and the telescopic rod 500, the present invention enables the installation box 100 to be first fixed to the utility pole through the clamp 600, and then to be raised in a cooperative manner, so that the installation box 100 can be more stable when the utility pole is raised, which not only avoids the problems of impact instability caused by direct lifting, but also saves physical strength, which can facilitate workers to install with less effort; a detailed description will be given later.

[0043] It is worth noting that the driving shaft 310 controls the bent rod 340 and the connecting rod 330 to make the pull rod 350 rise and fall, thereby closing the circuit breaker.

The limit spring 550 can play a limiting role and support the telescopic rod 500 through the compression elastic force, which will be described in detail later.

[0046] Furthermore, one end of the bottom plate 410 away from the second hinge groove 420 is fixedly connected to a limit plate 460, a notch 461 is vertically penetrated on the limit plate 460, a lower support block 830 is provided on one side of the notch 461, and the lower support block 830 is fixedly connected to the second hinge end 831; one end of the telescopic tube body 540 away from the telescopic rod body 530 is fixedly provided with a third hinge groove 542, the second hinge end 831 passes through the notch 461 and the second hinge end 831 is hinged to the third hinge groove 542;

At this time, under the action of the upper clamp 600 and the fixing mechanism 400, the installation box 100 can still be fixed; then the telescopic rod 500 is pushed upward, and the limit spring 550 is first compressed and then reset; when the lower support block 830 slides to above the notch 461, the reset spring 860 is also compressed, but under the control of the rebound force of the limit spring 550 and the angle of the telescopic rod 500, the lower support block 830 will be limited to above the notch 461 and will not move.

[0050] It is worth noting that this installation method is only suitable for the first installation of utility poles or when there are no other redundant fixings on the utility poles.

[0051] Furthermore, the lower connecting member 840 and the upper connecting member 820 have the same structure; one side of the lower connecting member 840 is fixedly connected to the lower support block 830, and the other side of the lower connecting member 840 is provided with a transverse sliding groove 841, and a second sliding rod 842 is fixedly connected to the transverse sliding groove 841, and two sliders 630 are slidably connected to the second sliding rod 842; a first tightening spring 843 is provided between each slider 630 and one end of the transverse sliding groove 841, and the first tightening spring 843 is sleeved on the second sliding rod 842; the two ends of the first tightening spring 843 are respectively fixedly connected to the corresponding slider 630 and the transverse sliding groove 841; the two sliders 630 are jointly fixedly connected to the clamp 600.

[0052] Furthermore, the clamp 600 includes two first arc blocks 610 and two second arc blocks 660; both ends of each first arc block 610 are fixedly provided with a first receiving block 620, and both ends of each second arc block 660 are fixedly provided with a second receiving block 670;

[0053] Each slider 630 is detachably fixedly connected to a first receiving block 620, and the other two first receiving blocks 620 are fixedly connected to a third slide bar 640; each third slide bar 640 is slidably connected to a second receiving block 670; a second limiting protrusion 641 is fixedly provided at one end of the third slide bar 640 away from the first receiving block 620, and a second tightening spring 650 is sleeved on the third slide bar 640, and the two ends of the second tightening spring 650 are respectively fixedly connected to the second receiving block 670 and the second limiting protrusion 641; the two first arc blocks 610 and the two second arc blocks 660 together form a quasi-circular structure.

[0054] Through the cooperation of the first tightening spring 843 and the second tightening spring 650, the two first arc blocks 610 and the two second arc blocks 660 can be adaptively expanded or contracted, so as to facilitate the rapid adjustment of the clamp 600, which will be described in detail later.

[0055] Furthermore, the insides of the two first arc blocks 610 are penetrated with steel wire rope installation holes 680; the insides of the two second arc blocks 660 and the insides of the second receiving blocks 670 of the second arc blocks 660 and away from the first arc blocks 610 are also penetrated with steel wire rope installation holes 680; a steel wire rope 690 is penetrated through all the steel wire rope installation holes 680, and the two ends of the steel wire rope 690 respectively pass through the steel wire rope installation holes 680 on the second receiving blocks 670 of the second arc blocks 660 and away from the first arc blocks 610;

[0057] The present invention adopts the structural design of the clamp 600, so that the clamp 600 can adapt to different thicknesses of electric poles, and can also adapt to electric poles of constantly changing thicknesses; when the first arc block 610 and the second arc block 660 are both mounted on the electric pole, if the electric pole is thicker, then the first tightening spring 843 and the second tightening spring 650 will be acted on to compress the first tightening spring 843 and the second tightening spring 650, at which time the first arc block 610 and the second arc block 660 will expand adaptively and cling to the electric pole; when it is necessary to fix the clamp 600, it is only necessary to lock the locking screw 682 to make the wire rope 690 tightly clamp the first arc block 610 and the second arc block 660. Yes, if necessary, the first receiving block 620 and the second receiving block 670 can be reinforced by other steel wires; when the clamp 600 needs to be loosened, the locking screw 682 can be loosened; and when the height of the installation box 100 needs to be adjusted, the clamp 600 can automatically adjust its adaptability according to the thickness of the pole. When the pole becomes thinner, the first tightening spring 843 and the second tightening spring 650 will be reset, so that the first arc block 610 and the second arc block 660 can be adaptively contracted and close to the pole. This can not only improve the installation adaptability and be suitable for a variety of poles, but also facilitate workers to quickly lock and loosen operations, and facilitate workers to quickly adjust the height of the installation box 100.

[0058] It is worth mentioning that when the first arc block 610 and the second arc block 660 are adaptively contracted, the wire rope 690 may be bent to a certain extent. At this time, it is only necessary to straighten the two ends of the wire rope 690.
