Telescopic columns 6 are movably installed through the top of the positioning plate 4 and located at the two limiting sleeves 5 respectively. A stud 7 is fixedly installed at the bottom of the telescopic column 6, and a knob 9 is fixedly installed at the top of the telescopic column 6. Bolt holes 10 are opened through the top of the positioning plate 4 near the front and rear ends.

[0025] Both positioning plates 4 are movably connected to the outer shell 1 via hinges. The spring 8 retracts inside the limiting sleeve 5. The positioning plates 4 are rotated and unfolded or folded to the bottom of the outer shell 1 via the hinges. The spring 8, located inside the limiting sleeve 5, drives the telescopic column 6 to slide.

[0026] The diameter of the telescopic column 6 is smaller than the diameter of the stud 7. The telescopic column 6 slides through the interior of the positioning plate 4. The stud 7 is located at the bottom of the positioning plate 4 to prevent the telescopic column 6 from popping out.

[0027] The bottom of the outer casing 1 has screw holes at each of the four corners for connecting the studs 7. The studs 7 are connected to the screw holes at the bottom of the outer casing 1 by thread. The studs 7 are fixed by connecting the positioning plate 4 to the screw holes at the bottom of the outer casing 1.

[0028] Specifically, by unfolding the two positioning plates 4 and rotating the knob 9 to connect the stud 7 with the reserved hole on the equipment, the outer shell 1 is fixed. The telescopic column 6, under the action of the spring 8, drives the stud 7 to retract inside the positioning plate 4. The bolt is fixed by connecting the bolt to the bolt hole 10.

When bolting, the telescopic column 6 drives the stud 7 to retract inside the positioning plate 4 under the action of the spring 8. The bolt is connected in the bolt hole 10 and fixed with the reserved hole of the equipment. When placing horizontally, the two positioning plates 4 are rotated and folded at the bottom of the outer shell 1. The stud 7 is connected and fixed with the screw hole at the bottom of the outer shell 1, so that the four knobs 9 are in contact with the plane and provide support, while reducing external scratches during transportation and carrying.

[0036] When providing protection, the protective plate 11 is pulled forward and rotated to a vertical position. The magnetic block 15 in the protective plate 11 is magnetically attracted and fixed to the magnetic block 15 at the bottom front of the outer casing 1. The protective plate 11 provides protection for the wiring terminals of the main unit inside the outer casing 1, reducing the entry of external dust during transportation and carrying. By rotating the protective plate 11 to a horizontal position, the protective plate 11 slides and retracts into the shrink groove 13, opening the wiring terminals of the main unit inside the outer casing 1 for cable connection.
