The front connection structure and the rear connection structure can disperse the reaction force of the transmission box gear from the gear to the horizontal plane between the front connection structure and the rear connection structure. Based on the above principle, the front connection structure and the rear connection structure of the curtain driver can avoid the use of screws for installation under the premise of simplification, and can effectively prevent the curtain driver from being structurally unstable or stripping. The embodiment of the utility model improves the installation stability of the curtain driver, can effectively avoid the problems of complex structure, high production cost, and inconvenient assembly and disassembly caused by the complex structure combined with screw installation, simplifies the corresponding structure of the curtain driver and the transmission box, and ensures the convenience of installation of the curtain driver.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
