[0024] Therefore, when the components in plug body 1 need to be overhauled, the upper shell 4 and the lower shell 5 of the plug body 1 are disassembled by the connecting unit, the plug body 1 is designed as a detachable structure, which is more flexible and convenient for subsequent maintenance and replacement of the components in the plug body 1, and the limiting unit limits the position of the control panel 3, reduces the possibility of position deviation of the control panel 3, and improves the stability of the control panel 3.

[0025] Referring to Figure 1 , the outer edges of the upper shell 4 and the lower shell 5 are provided with a plurality of inwardly recessed anti-skid grooves 17, and the plurality of anti-skid grooves 17 are uniformly distributed along the outer edges of the upper shell 4 and the lower shell 5, respectively. The anti-skid grooves 17 increase the friction between the operator's hand and the plug body 1, reduce the possibility of dropping the plug body 1 when the operator holds it, and facilitate the operator to hold the plug body 1. A plurality of display holes 15 are formed in the upper shell 4, and a display lamp for displaying the automobile diagnosis condition is installed in each of the plurality of display holes 15. In the embodiment of the present application, the number of display holes 15 and display lamps is three, respectively. For different results of automobile diagnosis, the three display lamps will light up in different colors, for example, the red, green and yellow colors of the display lamps can be used to distinguish different results of automobile diagnosis detection, so that the operator can intuitively know the result of automobile fault diagnosis. A paste groove 16 is formed in the upper shell 4, and a label matching the size of the paste groove 16 is arranged in the paste groove 16. In the embodiment of the present application, the label can be used to explain the different fault state information represented by different colors of the display lamp, so that the operator can easily and conveniently know the fault state represented by the lighting condition of the display lamp.
