[0083] Working principle:

[0084] When the narrowband communication equipment needs to be transported and installed: the whole equipment is moved to the emergency location by manual pushing, and then the driving motor 110 is used to control the driving rod 111 to rotate, thereby controlling the engaging gear 113 to drive the second gear 114 to rotate, and in turn drives the third gear 115, the fourth gear 116, the first belt 117, and the fifth gear 118 to rotate synchronously, thereby controlling the two upper installation boxes 200 to rotate and unfold in opposite directions, and when the two upper installation boxes 200 are unfolded, due to the change in the relative position of the sixth gear 221 and the fixed gear 119, the sixth gear 221 will rotate in the direction opposite to the rotation direction of the upper installation box 200. The first gear 112 on the driving rod 111 drives the seventh gear 317 and the rotating rod 315 to rotate through the third belt 318, so that the rotating rod 315 and the abutting member 314 can be screwed together to make the abutting member 314 move horizontally along the moving groove 313 toward the direction close to the abutting portion 322 until the supporting plate 222 abuts against the ground, thereby ensuring the stability of the overall equipment. At this time, the abutting member 314 and the abutting portion 322 are not abutted, and then the control motor 311 is driven to control The control rod 312 rotates, and due to the close fit between the control rod 312 and the inner groove of the sliding part 331, the rotation of the control rod 312 will drive the sliding part 331 to rotate synchronously, thereby driving the first rotating disk 321 to rotate through the control groove 325, and driving the second rotating disk 341 to rotate through the connecting plate 323, thereby driving the communication device 350 on the second rotating disk 341 to rotate until the antenna 351 on the communication device 350 rotates to the optimal position, and then the driving motor 110 controls the driving rod 111 to continue to rotate. At this time, since the support plate 222 is in contact with the ground, the engaging gear 113 rotates relative to the second gear 114 At the same time, the first gear 112 on the driving rod 111 will drive the abutment member 314 to move along the movable groove 313 through the above-mentioned transmission until the abutment member 314 abuts against the abutment portion 322 to limit the abutment portion 322, thereby ensuring the stability of the azimuth angle, and then the control motor 311 is used to control the control rod 312 to rotate. Since the abutment portion 322 cannot rotate, the sliding portion 331 will cooperate with the thread of the control rod 312 to make the sliding portion 331 move upward along the control groove 325, thereby driving the lifting member 333 to move upward, thereby controlling the communication device 350 to rotate along the rotating rod 352 until it rotates to the optimal position.

[0085] When the narrowband communication device is used, just reverse the above steps.
