By adopting the scheme, when the second shell is covered on the first shell, along with the continuous cover cap of the second shell, the limiting part on the second shell can be elastically pressed in the clamping groove under the elastic action of the elastic part along with the deepening of the cover cap when the second shell moves to the clamping groove position, so that the limiting part and the clamping groove form limiting fit, and the stability of connection between the first shell and the second shell is improved. In addition, the locating part can accomplish under the effect of elastic component and the draw-in groove butt in the twinkling of an eye between, can produce crisp impact sound under locating part and draw-in groove bumps, can indicate the user to install in place, prevents excessively to install. This scheme simple structure, processing simple to operate.

As a further setting of the utility model, the notch department of guide way is provided with the anticreep face that prevents that the locating part from deviating from the guide way.

By adopting the scheme, the anti-falling surface is arranged at the notch of the guide groove, so that the limiting part can be prevented from falling off from the guide groove, and particularly, the product is transported or moved.

As a further setting of the utility model, the locating part is the spheroid, the vertical cross-section of draw-in groove is the cambered surface, the anticreep is personally submitted with the curved surface of spheroid sphere adaptation.

Adopt above-mentioned scheme, through setting up the locating part into the spheroid to and the vertical cross-section of draw-in groove is the cambered surface, spacing between sphere and the cambered surface can prevent that the locating part from directly blocking to die with the spacing cooperation back of draw-in groove, and the user can be convenient for plug first casing and second casing under the application of force.

As a further arrangement of the utility model, the guide way extends to be formed with an opening that is used for locating part and elastic component to pack into to the second casing is outer, an opening part fixedly connected with closing cap.

By adopting the scheme, the opening communicated with the guide groove is formed in the second shell, so that the limiting part and the elastic part can be arranged in the guide groove through the opening, and the sealing cover is finally used for sealing, the structure is simple, and the processing is convenient.

The present invention will be further described with reference to the accompanying drawings.
