[0017] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0018] The utility model provides Figure 1-Figure 2 The shown terminal installation structure includes a shell 1, a wire insertion hole 3 is provided on the shell 1, a rotating column 6 is provided inside the shell 1, an operating panel 4 is rotatably provided on the rotating column 6, a power board 7 is also provided in the shell 1, and the power board 7 bypasses the rotating column 6, a notch is provided on the operating panel 4, a protrusion 8 is provided at one end of the power board 7, and the protrusion 8 is stuck in the notch to realize the connection between the power board 7 and the operating panel 4, a connecting column is provided on one side of the shell 1, and a connecting column socket is provided on the other side of the shell 1, and different shells 1 are connected by plugging the shell 1 into the connecting column socket, a detachable side panel 2 is provided on one side of the shell 1, and the outermost shell 1 is covered by the detachable side panel 2.

[0019] like Figure 3-Figure 5As shown, an installation chamber is opened in the upper right corner of the operating panel 4, and an operating rod 11 is set in the installation chamber. One end of the operating rod 11 is rotatably set on the column 10, and the column 10 is set in the upper left corner of the installation chamber of the operating panel 4. One end of the operating rod 11 is connected to the linkage plate 12. A square guide rod 14 is also set inside the operating panel 4. A lock tongue 13 is movably set on the square guide rod 14. A long slot is opened in the linkage plate 12. A boss is set at the left end of the lock tongue 13, and the boss is set in the long slot. When the operating rod 11 is pressed, the linkage plate 12 is selected clockwise, and the boss is pulled to retract the lock tongue 13. A movable slot 15 is opened on the lock tongue 13, and the square guide rod 14 is set in the movable slot 15 so that the lock tongue 13 can move left and right.
