When adjusting the length, use a tool compatible with the adjusting piece 111 to rotate the adjusting piece 111, and by reversing the adjusting piece 111, the adjusting piece 111 rises or falls inside the cylinder. The rise or fall of the adjusting piece 111 drives the mounting piece to move and adjust accordingly. The movement of the mounting piece and the adjusting piece 111 changes the placement space of the compression spring 110, thereby changing the movable range of the slider. When the adjusting piece 111 and the mounting piece move toward the inner side of the cylinder, the placement space of the compression spring 110 is compressed, thereby reducing the moving range of the slider, thereby shortening the stretching distance of the main arm and reducing the opening angle of the door. Conversely, the adjusting piece 111 and the mounting piece are twisted in the opposite direction so that the adjusting piece 111 and the mounting piece move toward the outer side of the cylinder, thereby extending the stretching distance of the main arm and expanding the opening angle of the door.

[0026] Secondly, there are two groups of mounting ears 102, which are fixedly connected to the shell 101 respectively and are located at both ends of the shell 101 respectively. Both ends of the shell 101 have mounting grooves 103 respectively, and each group of mounting grooves 103 is provided with multiple groups of threaded holes 104 inside. In the limiting shell, the regulating component is placed by the shell 101, and the limiting shell is installed and fixed by the mounting ears 102.

When adjusting the stretching length of the main arm, a tool adapted to the regulating piece 111 is used to rotate the regulating piece 111. By reversing the regulating piece 111, the regulating piece 111 rises or falls inside the cylinder. The rise or fall of the regulating piece 111 drives the installation piece to move and adjust accordingly. The movement of the installation piece and the regulating piece 111 changes the placement space of the compression spring 110, thereby changing the movable range of the slider. When the regulating piece 111 and the installation piece move toward the inner side of the cylinder, the placement space of the compression spring 110 is compressed, thereby reducing the moving range of the slider, thereby shortening the stretching distance of the main arm and reducing the opening angle of the door. Conversely, the regulating piece 111 and the installation piece are twisted in the opposite direction so that the regulating piece 1 11 and the mounting piece move toward the outside of the cylinder to extend the stretching distance of the main arm and expand the door opening angle.
