[0024] The beam body 1 is provided with an adjustment assembly 4, which includes a control rod 41, a pulley set 42, a first transmission cylinder 43, a second transmission cylinder 44, a stop ring 45, a stop block 46, an auxiliary spring 47, a first auxiliary block 48, a friction ring 49, a second auxiliary block 410 and a plurality of balls 411. The control rod 41 is movably arranged on the beam body 1, the pulley set 42 is movably arranged inside the beam body 1, the first transmission cylinder 43 and the second transmission cylinder 44 are both rotatably arranged inside the beam body 1, and the stop ring 45 and the stop block The first auxiliary block 48, the friction ring 49 and the second auxiliary block 410 are all slidably arranged inside the beam body 1, the first auxiliary block 48, the friction ring 49 and the second auxiliary block 410 are all fixedly installed on the control rod 41, and a plurality of balls 411 are movably arranged on the first auxiliary block 48 and the second auxiliary block 410, respectively, so that the first auxiliary block 48 and the second auxiliary block 410 can be movably connected with the stop ring 45 and the stop block 46, thereby ensuring the rationality of the overall structure, and there will be no mutual interference between the components during operation, and the stop ring 45 and the first transmission cylinder 43 are connected. The adjacent side surfaces are provided with raised friction patterns for enhancing friction and cooperating with the first transmission cylinder 43, and the side surfaces adjacent to the stop block 46 and the second transmission cylinder 44 are also provided with raised friction patterns for enhancing friction and cooperating with the second transmission cylinder 44. Both sides of the friction ring 49 are respectively provided with raised friction patterns for enhancing friction and cooperating with the second transmission cylinder 44 and the first transmission cylinder 43, to ensure that the established structure can operate stably and reasonably, thereby achieving the purpose of establishing such structures in advance. There are two auxiliary springs 47, one of which is fixedly connected to the stop ring 45 and the beam body 1 at both ends, and the other is fixedly connected to the stop block 46 and the beam body 1 at both ends. The first transmission cylinder 43 is connected to the screw rod 34 through a pulley group 42, and the second transmission cylinder 44 is also connected to the screw rod 34 through a pulley group 42, to improve the flexibility of the overall structure, and a knob is provided on the end of the control rod 41 passing through the beam body 1, and the knob is provided with anti-slip patterns to facilitate the actual operation of the user.

[0025] Working principle: the pillar 2 is fixed on the beam body 1, and the connecting tube 33 fixed on the extension rod 31 slides on the pillar 2, and the screw rod 34 rotating inside the pillar 2 is also threadedly connected to the connecting tube 33. As the screw rod 34 rotates, the connecting tube 33 will push the extension rod 31 to slide up and down, thereby raising the height of the connecting seat 32 fixed on the end of the extension rod 31 to meet the actual installation height requirements of the photovoltaic bracket.

[0026] When the screw rod 34 is actually driven to rotate, the operating rod 41 in the active state on the beam body 1 is pressed down, so that the second auxiliary block 410 fixed on the end of the operating rod 41 pushes the stop block 46 downward, so that the stop block 46 does not contact the second transmission cylinder 44. At this time, the friction ring 49 fixed on the operating rod 41 contacts the second transmission cylinder 44, because the side surfaces of the friction ring 49 and the side surfaces of the stop block 46 are both provided with fine protrusions that cooperate with the second transmission cylinder 44 to enhance friction, and the stop block 46 is The interior of the beam body 1 is in a sliding state. Therefore, when the friction ring 49 contacts the second transmission cylinder 44 and the stop block 46 does not contact the second transmission cylinder 44, the control rod 41 is rotated again, and the second transmission cylinder 44 will rotate with it. The second transmission cylinder 44 and the screw rod 34 are driven by the pulley group 42, so that the screw rod 34 can be driven to rotate and adjust the position of the connecting seat 32. The upper surface of the friction ring 49 and the lower surface of the stop ring 45 are also provided with a friction enhancing member and a friction member that is in contact with the first transmission cylinder 43. The stop ring 45 is also in a sliding state inside the beam body 1 due to the several fine friction pattern protrusions that match. Therefore, when the operating rod 41 is pulled up, the first auxiliary block 48 pushes the stop ring 45 upward, so that the stop ring 45 does not contact the first transmission cylinder 43. When the friction ring 49 contacts the first transmission cylinder 43, the operating rod 41 is rotated again, and the first transmission cylinder 43 will rotate with it. The first transmission cylinder 43 utilizes another pulley group 42 and another screw rod 34 for transmission, thereby achieving the purpose of controlling the height of the connecting seat 32 at different positions. After the operating rod 41 is released, the two auxiliary springs 47 respectively connect the stop ring 45 and the stop block 46 to the inside of the beam body 1. Therefore, under the action of the two auxiliary springs 47, the stop ring 45 and the stop block 46 return to the initial position and contact the first transmission cylinder 43 and the second transmission cylinder 44 respectively. Under the action of the friction patterns raised on their surfaces, the first transmission cylinder 43 and the second transmission cylinder 44 are restricted from moving, thereby locking the state of the connecting seat 32.
