When the two ends of the conductive rod 904 are in contact with the second contact 914, the electromagnet 912 is supplied with a reverse current to generate an attractive force on the magnetic block 901. When the push rod 907 is pulled back, since the movable plate 903 is movably connected to the movable groove 902, the two ends of the conductive rod 904 are first in contact with the two first contacts 913, so that the electromagnet 912 generates a repulsive force on the magnetic block 901, so that the two back plates 701 are separated from each other, and then the push rod 907 continues to pull back, pulling the second slider 802 back, driving the side protection plate 708 and the front protection plate 709 to rotate to their original state, so as to protect the device body 1. The top of the device body 1 is fixedly installed with a handle 3, and the push rod 907 A card slot 10 is provided at the top of the device body 1, an antenna 4 is provided above the device body 1, the antenna 4 is inserted into the card slot 10, one end of the antenna 4 is rotatably mounted on the rotating frame 5, the rotating frame 5 is fixedly mounted on the top of the device body 1, a positioning clip 6 is installed at the top of the device body 1, the positioning clip 6 limits the antenna 4, a card slot 10 is provided at the top of the push rod 907, and the antenna 4 at the top of the device body 1 is rotatably connected to the device body 1 through the rotating frame 5. When communication is required, the antenna 4 rotates upward so that the antenna 4 is disengaged from the card slot 10, which facilitates the movement of the push rod 907. When it is not needed, the antenna 4 is engaged with the card slot 10, the push rod 907 is engaged and fixed, and the positioning stability of the side protection plate 708 and the front protection plate 709 is improved.

[0035] Working principle: When the device body 1 is not in use, the two side protection plates 708 are symmetrically arranged on both sides of the device body 1, and the two front protection plates 709 block the front of the device body 1, so as to protect the device body 1 on the one hand and prevent the operation panel 2 from being accidentally touched on the other hand when the device body 1 is stored;

[0036] When it is needed, the antenna 4 is rotated upward around the rotating frame 5 to a vertical state, so that the antenna 4 is disengaged from the card slot 10, and the push rod 907 is pushed toward the second slider 802, and the second slider 802 is pushed to move along the second slide slot 801 toward the back plate 701 through the baffle 906. Since the rack 8052 is meshed with the gear 707, when the second slider 802 moves, the first side plate 8051 is driven to move, so that the baffle 906 rotates until the side protection plate 708 rotates to a position flush with the first slider 702, so that the two front protection plates 709 rotate to the two sides of the device body 1;

[0037] During the movement of the push rod 907, the movable plate 903 is inserted into the power connection box 911, so that the two ends of the conductive rod 904 on the movable plate 903 are respectively in contact with the two second contacts 914, so that the electromagnet 912 is supplied with a reverse current, generating an attraction force on the magnetic block 901. Under the action of the attraction force, the movable block 8056 moves along the cross bar 803 toward the second slider 802, and then pushes the two back plates 701 to approach each other along the first slide groove 703 until the two front protection plates 709 are respectively in contact with the side walls of the device body 1. In this process, the plug plates 711 on the two back plates 701 are inserted into the slots 710. When the two back plates 701 are in close contact, the device body 1 can be put on the clothes by the clamping force, so that the device body 1 is convenient to carry when in use;

[0038] When it is necessary to retract, the push rod 907 is pulled back. Since the movable plate 903 is movably connected to the movable groove 902, the movable plate 903 moves relative to the second slider 802 until the stop block 905 contacts the second slider 802. At this time, the two ends of the conductive rod 904 are respectively in contact with the two first contacts 913, so that the electromagnet 912 is supplied with a positive current, so that the electromagnet 912 generates a repulsive force on the magnetic block 901. Under the action of the repulsive force, the two back plates 701 move back, and then the push rod 907 continues to pull back, pulling the second slider 802 back, and through the engagement of the rack 8052 and the gear 707, the side protection plate 708 and the front protection plate 709 are driven to rotate to their original state.
