[0028] When ready for use, the base 11 is fixed at a designated position, and then the operator drives the connecting block 24 to move on the inner wall of the fixed box 22 through the driving mechanism 26, so that the connecting block 24 drives the rack 25 to move back and forth, thereby driving the gear 1 23 to rotate. The rotation of the gear 1 23 drives the L-shaped rod 14 to rotate on the fixed box 22, so that the L-shaped rod 14 drives the elevation angle of the transmitting antenna 13 to change through the fixed arm 12, and the angle adjustment range of the transmitting antenna 13 is limited by the length of the rack 25 to prevent the operator from colliding with the fixed arm 12 and then damaging the base 11 due to improper operation.
