[0013] Reference Figure 1 to Figure 2 The utility model is further described in detail.

[0014] The utility model discloses a connector for aluminum profiles, including a connector body 1, the connector body 1 includes a connecting block 10 arranged in an L shape, two ends of the connecting block 10 are respectively provided with through grooves 100 penetrating the two sides of the connecting block 10, two top blocks 11 are provided in the through grooves 100 in a sliding fit, a driving block 12 located between the two top blocks 11 is further provided at the center of the through grooves 100, the driving block 12 is close to the two sides of the two top blocks 11 and is provided with a first driving surface 13 inclined inwardly, and the two top blocks 11 are provided with a first driving surface 13 inclined inwardly. A second driving surface 14 that slides with the first driving surface 13 is provided on one side of the block 11 close to the driving block 12, and two adjusting screws 15 that are gap-set are provided on the surfaces at both ends of the connecting block 10, and the two adjusting screws 15 are threadedly matched with the connecting block 10, and one end of the two adjusting screws 15 extends to the upper surface of the driving block 12, and a circular groove 120 that is rotationally matched with the two adjusting screws 15 is provided on the upper surface of the driving block 12, and a straight groove 150 is provided at the end of the two adjusting screws 15.

[0015] Furthermore, in order to prevent the adjusting screw 15 from loosening due to external force vibration, a threaded fixing nut 2 is provided on the two adjusting screws 15, and the fixing nut 2 is provided in a conflicting fit with the upper surface of the connecting block 10. By providing the fixing nut 2 for further clamping and limiting, the adjusting screw 15 is not easy to loosen, thereby improving the connection stability of the connecting piece.

[0016] Furthermore, in order to improve the stability of the top block 11 during driving, two guide rods 3 are arranged at the bottom of the two top blocks 11 , and a sliding groove 101 slidably matched with the two guide rods 3 is arranged on the bottom wall of the through groove 100 .

[0017] Furthermore, in order to improve the convenience during installation, two rubber strips 4 are arranged between the two top blocks 11, and the two ends of the two rubber strips 4 are respectively fixed on the two guide rods 3. During installation, the two top blocks 11 will always be in the through groove 100 through the elastic force of the rubber strips 4, which is convenient for people to install later.
