BACKGROUND OF INVENTION
1. Field of the Invention
The present invention relates to a reel device of diversion joint, and more particularly to the reel device whose telegraph line can be pulled and collected.
2. Description of the Prior Art
To change with each passing day, a personal computer is popular and Computer, Communication, and Consumer Electronics are advanced by adjusting the different peripheral equipments such as different standards of joints and signal lines. Since Window 98, an USB (Universal Serial Bus) is a new transmission data interface. Particularly, the business-man or traveler usually needs two different specification joints for extending a signal line. How the users reserve the joint for the signal lines is the problem.
For solving the above-mentioned problem, a telegraph line has been developed for a reel-shaft box structure, in which the reel-shaft box structure has a shell, a telegraph line, a spiral spring, and also the signal lines, and the peripheral telegraph part. The inside signal line is stored via a reverse mechanism and extends to connect a joint of the shell. While the inside signal line is rotated, it keeps contacting with the shell. The signal line is directly to extend outside by a pull position-restored mechanism. The outside of signal line can be pulled by the spiral spring of the pull position-restored mechanism to extend an appropriate length. For finishing, the pull position-restored mechanism to release the telegraphy lines part can roll up automatically.
In view of the shortcomings of the prior art, the inventor of the present invention based on years of experience in the antenna field to conduct experiments and modifications develops a reel device of diversion joint to overcome the foregoing shortcomings.

DETAILED DESCRIPTION
In the related figures of a preferred embodiment, the same referring numerals are used for the same components of an input apparatus in accordance with the present invention.
Refer to 1A and 1B for an exploded view and an assembly view of a reel device of diversion joint in accordance with the present invention. Our reel device of diversion joint comprises: a casing 11, a wire holder 12, a telegraph line 17, a position plate 15 and at least an L-shape anchor 16. The casing 11 has an upper casing 111 and a lower casing 112, and also the lower casing 112 has a shaft 113. The wire holder 12 is mounted on the lower casing 112, the edge of the surface of the wire holder 12 is almost parallel to an extend direction 92 of the shaft 113. The wire holder 12 has a shaft hole 121 for the shaft 113 to penetrate therethrough. The wire holder 12 is to rotate about the shaft 113. The casing 11 has a restraint cavity 114 for accommodating the L-shape anchors 16 thereinside between the upper casing 111 and the position plate 15. The L-shape anchor 16 located inside the restraint cavity 114 is to allow a one-way clutching of the device. The telegraph line 17 has at least a terminal 18 and a winding structure 19 for the telegraph line 17 to be winded therealong. The winding structure 19 is located in the wire holder 12. Therefore, the telegraph line 17 can be located in the wire holder 12, and a portion of telegraph part 17 is close to the edge surface of the wire holder 12.
Refer to FIG. 2 for a schematic view of the position plate 15 of FIG. 1A. The position plate 15 is located on the wire holder 12 as well as on the winding structure 19. The position plate 15 has a guiding groove 151 with a predetermined shape. The guiding groove 151 is spirally extended on a surface almost perpendicular to the shaft 113 and is formed by four structural islands 152 protruding toward the upper casing 111 on the position plate 15. The four protruding structural islands 152 are symmetrically designed, and two opposing structural islands 152 have corresponding anchor recesses 153 communicated in space with the guiding groove 151.
Refer to FIG. 3 for a schematic view of a pair of the L-shape anchors 16 of FIG. 1A. The L-shape anchor 16 located and moving between the upper casing 111 and the position plate 15 within the restraint cavity 114 has a long-length leg 161 and a short-length leg 162. The long-length leg 161 and the short-length leg 162 are perpendicular. The L-shape anchor 16 has a slider protrusion 163 located close to a free end of the short-length leg 162. The slider protrusion 163 is to slide along the guiding groove 151 and to anchor in the corresponding anchor recess 153 of the position plate 15. The long-length leg 161 is to move freely between the upper casing 111 and the position plate 15 and to be restrained within the restraint cavity 114. As shown in FIG. 1, two L-shape anchors 16 are paired to a bracket formulation and are set to two sides of the shaft 113 symmetrically.
Refer to FIG. 4 for an engagement state of the position plate 15 of FIG. 2 and the L-shape anchors 16 of FIG. 3. In the present invention, the terminal 18 has a linear movement 93 and a rotational movement 91 about the shaft 113 following the linear movement 91. By initiating the linear movement 93 as well as the rotational movement 91 of the telegraph line 17, the two slider protrusions 163 are pulled away from the corresponding anchor recesses 153 and enter inwards to slide along the guiding groove 151 about the shaft 113. While the pulling on the telegraph line 17 is off, the slider protrusions 163 would slide backwards and outwards a little bit along the guiding groove 151 to nest into the close anchor recesses 153.
