Universal Reel Device

A universal reel device, comprising an upper cover, a lower cover, a spool and a spiral spring, wherein the upper cover and the lower cover are fastened together, a center of the lower cover projects upwards to form a shaft, a center of the spool is formed with a through hole matching with the shaft, the shaft is inserted into the through hole so that the spool is rotatably mounted between the upper cover and the lower cover, and the characteristic lies in that:

• the spool comprises, from bottom to top, a bottom layer, a middle layer and a top layer, wherein a top portion of the top layer projects upwards to form a convex block for locking the spiral spring, the middle layer is an annular cable distributing disk, the cable distributing disk has a cable hooking slot for hooking a cable, each of an outer side of the upper cover and an outer side of the lower cover is formed with an opening, which is for placement of the cable and corresponds to the cable hooking slot;
• a U-shaped movable tongue for positioning is disposed between the bottom layer and the lower cover, an inner side of the lower cover is formed with a U-shaped position restricting slot matching with the U-shaped movable tongue, a middle of an arced path of the U-shaped movable tongue is formed with an upwardly projecting tongue member;
• a bottom portion of the bottom layer is formed with a planar track for movement of the tongue member, the tongue member is fit into the planar track so that the spool can drive the tongue member through the planar track and thus drive the U-shaped movable tongue to move in the U-shaped position restricting slot;
• and
• the universal reel device further comprises a safety switch for locking the spool.
