Detailed Description
For a better understanding of the present invention, the present invention is further described below in conjunction with specific embodiments.
Referring to fig. 1, 2, 3 and 4, the invention provides a cordless head making device of a spring 7 retractable curtain. The curtain or the roller shutter comprises a long shaft 6, and curtain devices are respectively sleeved at two ends of the long shaft 6. Taking a curtain head at one end as an example, a spring 7 is sleeved at one end of a long shaft 6, a spring cover 3 is sleeved outside the spring 7, the spring 7 adopts a sheet-shaped winding spring 7, the spring cover 3 is made into a cover shell 2, a baffle 4 is arranged on one side surface of the cover shell 2, a slotted hole is formed in the cover shell 2, the end of the spring 7 is fixedly arranged in the slotted hole, the cover shell 2 is sleeved with a support 1, the long shaft 6 is fixed, two side walls are arranged on the support 1, a raised line 11 is arranged on one side of the cover shell 2, a groove 10 is arranged on one side of the support 1, and one side of the cover shell 2.
