Abstract: A universal reel device includes an upper cover and a lower cover fastened together, a spool, a spiral spring and a safety switch for locking the spool. The spool has a bottom layer, a middle layer and a top layer. The middle layer is an annular cable distributing disk having a cable hooking slot. A bottom portion of the bottom layer is formed with a planar track and a U-shaped movable tongue for positioning is disposed between the bottom layer and the lower cover. The universal reel device can reel in various cable products, and may also be combined with a cable to form a single-pull or dual-pull reel. In use, a safety switch is used to lock the spool. The spool cannot rotate until the user unlocks the safety switch so that the high safety feature is obtained.

Abstract: A single free-end wire reel includes a leveled area disposed on a rotary member to level arc tracks and a gap formed at the intersection of the arc tracks to change the motion track of a limit block. The present invention not only keeps the limit block to have a dual-positioning function when doing a circular motion but also controls the length of a wire exactly, providing a smooth operation when extending or extracting the wire.

Abstract: A single pull wire winding device comprises a wire winding reel; the wire winding reel has two recesses respectively on both surfaces thereof for containing a flexible printed board and a coil spring, the wire winding reel having a peripheral groove on its periphery for containing a power connection wire, and a bulkhead on one side of the peripheral groove has at least one stopping portion; a switch is provided within the containing groove along a tangential direction of the wire winding reel so that the stopping block of the switch engages with the stopping portion of the wire winding reel to stop the rotation of the wire winding reel. Thus, the present invention, wherein a flatter flexible printed board is used to substitute for a portion of a thicker power connection wire to reduce the volume of the assembled device, is widely applied to various electronic products.

Abstract: An ear hanger for fixing a transmission line comprises a frame, a first containing section, a second containing section and a third containing section. The frame includes a hook portion and an abutting portion. The hook portion is formed at the upper end of the frame. The abutting portion is formed at the lower end of the frame. The first containing section is shaped along the hook portion and has a first opening. The second containing section is shaped along the abutting portion and has a second opening. The third containing section is shaped along the abutting portion, located between the first containing section, and the third containing section has a third opening. The third opening is opened on the side opposite to the positions where the first opening and the second opening are opened. Thus, the transmission line can be firmly mounted and is not easy to fall off.
