Gravity-free spring roller blind controller

A gravity-free spring roller blind controller, the controller being configured to be mounted on a shaft end of a hollow roller blind shaft, and the roller blind shaft being wound with a roller blind, wherein:

• the controller comprises a torque adjustment assembly and a torsion spring connecting rod assembly connected to each other;
• the torque adjustment assembly comprises a bracket, a torsion spring mounting seat fixed on the bracket, a guide sleeve rotatably sleeved on the torsion spring mounting seat, and a roller blind sleeve rotatably sleeved on the guide sleeve;
• the torsion spring connecting rod assembly comprises a connecting rod group coaxially fixedly connected to the guide sleeve, a torsion spring and an inner sleeve connected to one end of the torsion spring are mounted on the connecting rod group, the inner sleeve is fixedly connected to the roller blind shaft, and the roller blind shaft drives the torsion spring to rotate through the inner sleeve;
• a one-way torsion spring is sleeved on a mounting shaft of the torsion spring mounting seat, the guide sleeve is further rotatably sleeved with a torque adjustment knob, a first flange is provided within an inner cavity of the guide sleeve, and a second flange falling within the inner cavity is provided on the torque adjustment knob;
• when in a normal state, the first flange reversely pushes the one-way torsion spring so that the one-way torsion spring is locked tightly onto the mounting shaft;
• and
• when torque adjustment is performed, the torque adjustment knob is forwardly or reversely rotated, and the second flange forwardly or reversely drives the guide sleeve and the connecting rod group to rotate through a torsion arm of the one-way torsion spring, so that the torque of the torsion spring is increased or decreased.
