step 2: the first screw rod (3) is driven to rotate by rotating the turntable (23), the rotating first screw rod (3) can drive the second belt pulley (21) to rotate through the first belt pulley (20) and the transmission belt (22), and further drive the second screw rod (4) to rotate, when the first screw rod (3) rotates, the first screw rod nut (5) and the second screw rod nut (6) can simultaneously move towards opposite directions, when the second screw rod (4) rotates, the third screw rod nut (7) and the fourth screw rod nut (8) can simultaneously move towards opposite directions, the moving third screw rod nut (7) and the moving fourth screw rod nut (8) can respectively drive the first I-shaped sliding block (10) and the second I-shaped sliding block (11) to move, and under the matching of the first screw rod nut (5) and the second screw rod nut (6), the first clamping plate (12) and the second clamping plate (16) are driven to move towards opposite directions, further, the first airbag (13) and the second airbag (17) are respectively brought into contact with the left side surface and the right side surface of the signal receiving device body (36);
And step 3: then, the first air pump (14) is used for inflating the first air bag (13) through the first air conveying pipe (15) by starting the first air pump (14) and the second air pump (18), and further the first air bag (13) is expanded; the second air pump (18) is used for inflating the second air bag (17) through the second air transmission pipe (19), so that the second air bag (17) is expanded and enlarged, and the enlarged first air bag (13) and the enlarged second air bag (17) clamp and fix the signal receiving device main body (36);
and 4, step 4: then the protective door (24) is closed, the first magnet (26) is contacted with the second magnet (27) and attracted, and the installation of the signal receiving device main body (36) is completed;
and 5: in the use, when needs are cooled down to protection box (1) inside, through starting fan (35), with the inside air escape of protection box (1), and then make outside air enter into inside protection box (1) through trachea (31), and then accelerated the inside air flow of protection box (1) to inside cooling down to protection box (1).
