Abstract
A flexible printed circuit board reel device, which includes a left housing, a right housing, a rotary sleeve, an upper spiral spring and a lower spiral spring. The left housing and the right housing of the reel device are caught on each other to form a housing, and the left housing and the right housing are firmly and closely fixed with each other, which can increase the connection area, whereby the left and right housings are not easily separated from each other, and the housing can have a strong structure. The upper spiral spring, the lower spiral spring, an upper central shaft and a lower central shaft of the reel device form a symmetrical and balanced double-spring structure; when a flexible printed circuit board is reeled or unreeled, the force generated by the springs is evenly distributed over the upper portion and the lower portion of the rotary sleeve.
