Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] refer to Figure 1 to Figure 6 , a distribution box for preventing disengagement of the present invention, comprising a box body 1 and a tray 2, the box body 1 is provided with an opening slot 11 matching the tray 2, and the tray 2 is slidably connected in the opening slot 11. In order to realize automatic opening, a second spring 5 is arranged at the bottom of the opening groove 11, the outer end of the second spring 5 is connected with a push plate 51, the second spring 5 is arranged horizontally, and one end of the second spring 5 is against the opening groove 11 bottom, one end is fixedly connected with push plate 51. The length of the second spring 5 in the natural state is half of the length of the tray 2. In this design, the elastic force is enough to eject the tray 2, and the elastic force is too large to cause the ejection speed of th...
