There has been the device that rolls up longer diagnosis line among the prior art, like the OBD data connection extension line that china patent CN208835418U disclosed, including the line body, extension coil and female end, the winding wired body in the extension coil, sub-end and sub-end inboard are provided with the plug pin is connected to line body one end, female end is connected to the line body other end, female end inboard is provided with the spliced eye, female end one side and sub-end outside all are provided with the sealing washer, the inside conductor that is provided with of line body, the conductor outer surface is provided with the rubber insulation layer, the rubber insulation layer outside is provided with the corrosion-resistant layer, be provided with high temperature resistant layer between rubber insulation layer and the corrosion-resistant layer. When the retractable wire reel works, the wire body can be wound in the retractable wire reel, and can be freely drawn out or wound according to the use condition, so that the condition that the use is influenced by the fact that the wire body is not long enough or the wire body is too long can be avoided.

However, the winding structure is too simple, cannot realize convenient winding and unwinding, is difficult to extend the data transmission line, cannot automatically wind, is easy to cause disorder and knot, and the contraction speed of the data transmission line is uncontrollable.

Disclosure of Invention

The utility model provides a retractable OBD extension line satisfies the demand of different length to solve the problem of knoing in a jumble, clean and tidy pleasing to the eye easy operation.

The technical scheme of the utility model as follows: the utility model provides a retractable OBD extension line, includes data transmission line, first OBD plug (1 and second OBD plug, first OBD plug (1 with the second OBD plug is connected respectively data transmission line both ends, still including the protection that is provided with circular inner chamber and stiff end setting are in the inside coiler of protecting crust, be provided with on the protecting crust and be used for wearing out two outlet at data transmission line both ends, the winding of data transmission line is in the coiler outer fringe, be provided with the brake button who is used for pressing data transmission line on the protecting crust.

The utility model discloses the length of OBD diagnosis line can freely transform, and is scalable, and the dynamics control that brake button was pressed to shrink speed accessible can make data transmission line stop tensile or roll-up after brake button compresses tightly, makes the arrangement of OBD diagnosis line and accomodate and become more convenient.

Preferably, the coiler is spring box structure, adopts current structural installation, simple structure, and the installation of being convenient for is with low costs.

Preferably, the number of the brake buttons is two, the brake buttons are arranged at the positions of the wire outlets, and the brake button structure is simple in structure and convenient to process.

Preferably, the fixed end of the brake button is arranged on the shell of the protective shell, so that the structure is simple and the operation is convenient.

Preferably, the first OBD plug (1) is one of a pin type or a jack type, and the second OBD plug (2) is one of a pin type or a jack type, so that the interchange of different interfaces can be realized, the universality is good, and the convenient connection of different devices is realized.

The utility model has the advantages that:

1. the length of OBD diagnosis line can freely be changeed, satisfies the demand of different length, and convenient storage has solved the mixed and disorderly problem that easily knoes of data transmission line.

2. The automatic roll-up that realizes, the dynamics control that the shrink speed accessible was pressed brake button, and it is more convenient that the arrangement becomes with accomodating.
