[0024] See also Figure 1 A tensioner for power installation comprises two fixed frames 1, one side of the fixed frame 1 is rotatably connected with a rotating shaft 2, a cable stick 3 is fixedly installed outside the rotating shaft 2, a motor frame 4 is fixedly installed on the left side of the fixed frame 1 on the left, a motor 5 is fixedly installed inside the motor frame 4, a clamping component 7 is fixedly installed on the right side of the fixed frame 1 on the right, the right side of the rotating shaft 2 penetrates the fixed frame 1 and extends to the other side of the fixed frame 1 where an extension component 6 is fixedly installed, and the output shaft of the motor 5 penetrates the fixed frame 1 and extends to the other side of the fixed frame 1 and is fixedly connected to the left side of the rotating shaft 2.

[0025] according to Figure 2-4 As shown, the extension component 6 includes an extension shaft 61, a receiving groove 62 is provided on the outer wall of the extension shaft 61, an inner shaft 64 is fixedly installed inside the extension shaft 61, a clamping block 63 is slidably connected inside the receiving groove 62, a control shaft 65 is rotatably connected inside the inner shaft 64, a connecting rope 66 is wound around the outside of the control shaft 65, a connecting spring 67 is sleeved on the outside of the connecting rope 66, one end of the clamping block 63 is fixedly connected to one end of the connecting spring 67, and the other end of the connecting spring 67 is fixedly connected to the outer wall of the inner shaft 64, a plurality of rope holes are arranged in an array on the outer wall of the inner shaft 64, and the rope holes and the connecting rope 66 are interlaced, a rotating disk 68 is fixedly installed on one side of the control shaft 65, a first magnetic block is fixedly installed on the inner side of the rotating disk 68, and a second magnetic block is fixedly installed on the outer side of the extension shaft 61, and the magnetic poles of the first magnetic block and the second magnetic block on the opposite side are opposite.

[0026] according to Figure 2-4 As shown, the clamping assembly 7 includes a fixing ring 71 , and a plurality of fixing teeth 72 are arranged in a uniform array inside the fixing ring 71 . The number of the fixing teeth 72 is the same as the number of the clamping blocks 63 , and the fixing teeth 72 and the clamping blocks 63 are arranged alternately.

[0027] Working principle: through the setting of the extension component 6 and the clamping component 7, after the cable stick 3 is driven to rotate by starting the motor 5 and the cable stick 3 is used to reel in the cable, it is necessary to stabilize the cable on the outer surface of the cable stick 3, and usually in order to ensure that the cable is in a straight state, when the motor 5 stops, the setting of the clamping component 7 can make the extension component 6 unable to rotate. Because the extension component 6 cannot rotate, the cable stick 3 can be prevented from self-rotation, so that the cable can still be kept straight after the cable stick 3 stops working. As for how the clamping component 7 realizes the clamping rotation of the extension component 6, the specific operation is: by rotating the rotating disk 68, the first magnetic block on the inner side of the rotating disk 68 is no longer in contact with the second magnetic block on the surface of the extension shaft 61. At this time, the connecting spring 67 needs to be When the clamping block 63 is restored to its original state, it will push the clamping block 63 to move outward. Because the clamping block 63 always moves outward, the clamping block 63 and the fixed tooth 72 are staggered and engaged. Because the position of the fixed ring 71 is fixed, the staggered engagement of the clamping block 63 and the fixed tooth 72 can prevent the extension shaft 61 from rotating. Therefore, the cable stick 3 cannot rotate by itself, so that the cable always remains taut. Before starting the motor 5, the rotating disk 68 is rotated so that the first magnetic block on the inner side of the rotating disk 68 and the second magnetic block on the outer side of the extension shaft 61 are attracted to each other, and the clamping block 63 can be pulled back to the inside of the extension shaft 61 through the connecting rope 66. At this time, the clamping block 63 is no longer engaged with the fixed tooth 72, so that the start of the motor 5 can easily drive the cable stick 3 to rotate.
