[0032] Since the outer surface of moving block 4 is slidably connected with the inside of the outer surface of support arm 2, moving block 4 can only move along the inside of the outer surface of support arm 2, when moving block 4 moves, it will drive rack 3 to slide in the inside of support arm 2, since the outer surface of rack 3 is engaged with the inside of two gears 5, when rack 3 slides along the inside of support arm 2, it will drive two gears 5 to rotate in the opposite direction with the sleeve of two fixed blocks 6 as the axis, at the same time, two clamping blocks 7 will be driven by two gears 5 to rotate in the opposite direction, then two clamping blocks 7 will clamp the conductor in the opposite direction, since the design of first toothed plate 8, the fixing effect of clamping block 7 on the conductor can be improved.

[0033] Wherein, the inside of movement board 1 is fixedly sleeved with threaded sleeve 9, the outer surface of threaded sleeve 9 is threadedly sleeved with rotating block 10.

[0034] Since the inside of rotating block 10 is threadedly sleeved with threaded sleeve 9, when rotating block 10 rotates, it will move backward along the outer surface of threaded sleeve 9 at the same time.

[0035] Wherein, the outer surface of rotating block 10 is movably sleeved with circular ring 11, the outer surface of circular ring 11 is fixedly installed with first hinged block 12.

[0036] Since the inside of circular ring 11 is movably sleeved with the outer surface of rotating block 10, when rotating block 10 rotates and moves backward at the same time, it will drive circular ring 11 to move backward, at this time, circular ring 11 will drive several first hinged blocks 12 to move backward at the same time.

[0039] The inner part of the movement plate 1 is movably sleeved with a long rod 14, and the other end of the long rod 14 is fixedly installed with a fixed plate 15.

[0040] Since the inner part of the movement plate 1 is movably sleeved with the outer surface of the long rod 14, the movement plate 1 can move forward and backward along the outer surface of the long rod 14.

[0041] The inner part of the fixed plate 15 is movably sleeved with a screw rod 16, the outer surface of the screw rod 16 is threadedly sleeved with the inner part of the threaded sleeve 9, and the front section of the screw rod 16 is fixedly installed with a twisting block 17.

[0042] When the twisting block 17 is twisted by the operator, the screw rod 16 will rotate around the sleeving position of the fixed plate 15 under the driving of the twisting block 17. Since the outer surface of the screw rod 16 is threadedly sleeved with the inner part of the threaded sleeve 9, when the screw rod 16 rotates, the movement plate 1 will be driven by the threaded sleeve 9 to move forward along the outer surface of the long rod 14, and at this time, several groups of clamping blocks 7 can adjust the tightness of the wires in the movement.

[0043] The front surface of the fixed plate 15 is fixedly installed with a long plate 18, the inner part of the front end of the long plate 18 is fixedly installed with a limiting rod 19, the outer surface of the limiting rod 19 is movably sleeved with a chuck 25, and the chuck 25 is provided with a second toothed plate 26.

[0044] Due to the design of the limiting rod 19, the movement of the chuck 25 is limited, and when the two chucks 25 move towards each other along the outer surface of the limiting rod 19, the cross bar of the power transmission tower can be clamped, thereby achieving the effect that the tight line device is connected with the power transmission tower. Due to the design of the second toothed plate 26, the connection effect of the tight line device and the power transmission tower can be enhanced.

[0045] The back surface of the limiting rod 19 is fixedly installed with an air cylinder 20, and the rear end of the air cylinder 20 is fixedly installed with a square block 21.

[0046] When the air cylinder 20 moves, the square block 21 will move backward.

[0047] The left and right sides of the square block 21 are fixedly installed with second hinge blocks 22, and the inner parts of the second hinge blocks 22 are hingedly connected with movable rods 23.

[0048] When the square block 21 moves backward, the two movable rods 23 will be driven to move by the two second hinge blocks 22.

[0049] The other end of the movable rod 23 is hingedly connected with a third hinge block 24, and the front surface of the third hinge block 24 is fixedly connected with the rear end of the chuck 25.

[0050] When two active rods 23 move, two third hinged blocks 24 will be driven to move, and two clamps 25 will be driven to move towards each other.

[0051] The working principle and use process of the utility model are as follows:

[0052] When the operator needs to tighten the wire, first, the operator moves two clamps 25 to the crossbar of the power transmission tower, and then the operator starts the cylinder 20, at this time, the rear end of the cylinder 20 drives the square block 21 to move backward, at this time, the square block 21 drives two second hinged blocks 22 to move, then two second hinged blocks 22 drive two third hinged blocks 24 to move through two active rods 23, and then two third hinged blocks 24 drive two clamps 25 to move, because the inside of the clamp 25 is movably connected with the outer surface of the limiting rod 19, the movement of the clamp 25 will be limited by the limiting rod 19, at this time, two clamps 25 will move towards each other along the outer surface of the limiting rod 19 under the drive of two third hinged blocks 24, at this time, two clamps 25 will clamp the crossbar of the power transmission tower in the movement towards each other, so that the whole tightening device is connected with the power transmission tower, thereby realizing the function that the tightening device can be conveniently installed on the power transmission tower, and the stability of the connection between the tightening device and the power transmission tower can be enhanced due to the design of two second toothed plates 26.

[0053] When the operator needs to fix the wire, at this time, the operator places the wire between the clamping blocks 7, and then the operator twists the rotating block 10, because the inside of the rotating block 10 is threadedly connected with the outer surface of the threaded sleeve 9, when the rotating block 10 rotates along the outer surface of the threaded sleeve 9, it will move backward at the same time, because the inside of the circular ring 11 is movably connected with the outer surface of the rotating block 10, at this time, the circular ring 11 will move backward under the drive of the rotating block 10, at the same time, the first hinged blocks 12 will move under the drive of the circular ring 11, at this time, the first hinged blocks 12 will drive the movement rods 13 to move, at this time, the other end of the movement rods 13 will push and extrude the movement blocks 4, so that the movement blocks 4 drive the racks 3 to slide along the inside of the supporting arms 2, because the outer surface of the rack 3 is meshed and connected with the outer surface of the gear 5, when the racks 3 move, the gears 5 will rotate in the opposite direction with the hinged parts of the fixed blocks 6 as the axis, at the same time, the clamping blocks 7 will rotate in the opposite direction under the drive of the gears 5, then the clamping blocks 7 will clamp and fix the wires in the opposite direction rotation, thereby realizing the function that the multiple wires can be conveniently clamped and fixed, and the fixing effect of the clamping blocks 7 on the wires can be enhanced due to the design of the first toothed plate 8.

[0054] Subsequently, the operator twists the twisting block 17, at this time, the screw rod 16 will rotate under the drive of the twisting block 17, since the outer surface of the screw rod 16 is sleeved with the internal thread of the threaded sleeve 9, when the screw rod 16 rotates, the movement plate 1 will be driven to move as a whole through the threaded sleeve 9, since the long rod 14 is designed, the movement of the movement plate 1 as a whole will be limited, at this time, the movement plate 1 as a whole will move forward along the outer surface of the long rod 14 under the drive of the threaded sleeve 9, in this process, the tightness of the wire can be adjusted.
