[0006] Furthermore, two groups of sliding mounting parts are provided on the right sides of the first wire box and the second wire box, and two groups of sliding grooves are provided on the left sides of the second wire box and the third wire box.

[0007] Furthermore, the structural specifications of the sliding groove correspond to those of the sliding mounting portion, and the sliding mounting portion is installed in a sliding manner in cooperation with the sliding groove.

[0008] Furthermore, a spring is fixedly installed in the mounting hole, the upper end of the spring is fixedly connected to a positioning column, and a front end of the positioning column is provided with an arc portion.

[0009] Furthermore, a positioning installation hole is provided between the upper and lower side walls of the embedded box, and the positioning installation hole is contacted and fitted with the positioning column.

[0010] The beneficial effect of the utility model is that the required wire boxes are assembled according to needs through the cooperation of multiple groups of sliding mounting parts and sliding grooves, and then the assembled wire boxes are inserted into the embedded box as a whole. When inserted, the arc part contacts the inner wall of the embedded box and stretches toward the inside of the mounting hole until it cooperates with the positioning mounting hole. At this time, under the action of the spring, the positioning column extends into the inside of the positioning mounting hole to complete the fixation, which is simple to install and saves time and effort.
