[0024] The fixing assembly 4 includes a hollow cylinder 41, which is fixedly connected to the lower surface of the fence body 1. A slide groove 42 is provided on the inner surface of the hollow cylinder 41. The cross-sectional shapes of the slider 421 and the slide groove 42 are both "T"-shaped. A slider 421 is slidably provided in the slide groove 42. A tooth plate 43 is fixedly provided on the side of the slider 421 away from the slide groove 42. A support block 44 is fixedly provided on the lower surface of the tooth plate 43. The support block 44 is movably fitted with the inner surface of the hollow cylinder 41. A through groove 45 is provided on the outer surface of the hollow cylinder 41. A rotating rod 46 is rotatably provided on the inner surface of the through groove 45. A gear 47 is fixedly sleeved on the outer surface of the rotating rod 46. The gear 47 is meshed with the tooth plate 43. A fixing plate 48 is fixedly provided on the outer surface of the hollow cylinder 41. Second threaded holes 471 are provided on the outer surfaces of the gear 47 and the fixing plate 48. There are eight second threaded holes 471, and the second threaded holes 471 are distributed in a circular array on the outer surface of the gear 47. The second threaded hole 471 is threaded with a second screw 49. When the fence needs to be moved to a designated location, the fence body 1 can be pulled through the universal wheel 5 to move the entire fence to the destination. The fence body 1 is adjusted through the first rotating shaft 11 to make the two fence bodies 1 arc-shaped, enclosing the power well in the middle of the fence body 1. The gear 47 is turned to drive the tooth plate 43 to move downward, thereby causing the support block 44 on the lower surface of the tooth plate 43 to move downward. The position of the support block 44 exceeds the universal wheel 5, and the slider 421 cooperates with the slide groove 42 to assist in supporting the movement of the tooth plate 43, and also serves as a limiter. After adjusting to a suitable position, the second screw 49 is inserted into the corresponding second threaded hole 471 for fixing, so that the fence body 1 stands on the ground and will not move.

[0025] Furthermore, the adjustment component 3 includes a sleeve plate 31, which is rotatably connected to the outer surface of the second rotating shaft 12. A square groove 32 is opened in the middle of the sleeve plate 31, and a movable plate 33 is slidably arranged in the square groove 32. A connecting block 34 is fixed between the movable plates 33. The upper surfaces of the sleeve plate 31 and the movable plate 33 are both opened with a first threaded hole 35, and a first screw 36 is threadedly inserted in the first threaded hole 35. There are a plurality of first threaded holes 35, and the first threaded holes 35 are arrayed on the upper surfaces of the movable plate 33 and the sleeve plate 31. The first screw 36 can be rotated to disengage its end from the first threaded hole 35 to release the fixation of the movable plate 33, and the movable plate 33 can be pulled outward to expand the fence body 1 outward to adjust the size of the fence body 1. After the adjustment is completed, the first screw 36 is inserted into the corresponding first threaded hole 35 for fixing, which is convenient for adjustment according to power wells of different sizes. After use, it is also convenient for folding and transportation.

[0026] Working principle: When the utility model is in use, when it is necessary to move the fence to a designated location, the fence body 1 can be pulled through the universal wheel 5 to move the whole to the destination, and the fence body 1 can be adjusted through the first rotating shaft 11 to make the two fence bodies 1 arc-shaped, and the power well is surrounded in the middle of the fence body 1. By turning the gear 47, it drives the tooth plate 43 to move downward, so that the support block 44 on the lower surface of the tooth plate 43 moves downward, and the position of the support block 44 exceeds the universal wheel 5. The slider 421 cooperates with the slide groove 42 to assist in supporting the movement of the tooth plate 43, and also plays a role in limiting the position. After being adjusted to a suitable position, the fence body 1 is fixed by inserting the second screw 49 into the corresponding second threaded hole 471 so that the fence body 1 stands on the ground and will not move. The first screw 36 can be rotated to disengage its end from the first threaded hole 35 to release the fixation of the movable plate 33. The movable plate 33 is pulled outward to expand the fence body 1 outward to adjust the size of the fence body 1. After the adjustment is completed, the first screw 36 is inserted into the corresponding first threaded hole 35 to fix it. This is convenient for adjustment according to power wells of different sizes. After use, it is also convenient for folding and transportation.
