Description

technical field [0001] The invention relates to a curtain accessory, in particular to a semi-automatic curtain control head. Background technique [0002] The curtain head is the main accessory to control the curtain retraction. It determines whether the curtain can be retracted freely and is easy to control. However, the current pull-bead curtain head is difficult to control the fixed state of retraction, and the manipulability is not strong. It is easy to make the curtain stretch too far, and the stability is not good. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a semi-automatic bead curtain control head. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A semi-automatic pull bead curtain head, characterized by comprising a housing, a clutch, a variable speed drive gear, an internal gear fixing plate, a pull bead gear, a drive pull bead chai...
