s3, after the use is finished, the first card box (1) and the second card box (4) are rotated, so that the supporting blocks (14) of the first card box (1) and the second card box (4) drive the rotating sleeve (13) to rotate around the roller (12) in the inner cavity of the T-shaped groove (22), the first card box (1) and the second card box (4) are combined, when the left side and the right side of the first card box are opposite to each other, the first card box (1) and the second card box (4) are pushed by hand to slide relatively along the T-shaped groove (22) of the installation backup plate (21) until the first card box (1) and the second card box (4) are attached to each other;
s4, after the first card box (1) is attached to the second card box (4), the T-shaped support frame (15) is rotated by bare hands, so that the T-shaped support frame (15) drives the semicircular limiting block (110) to rotate in the inner cavity of the first semicircular notch (19) clockwise or anticlockwise, the semicircular limiting block (110) can be rotated to the inner cavity of the second semicircular notch (41), the T-shaped notch (16) on the bottom end face of the semicircular limiting block (110) is clamped with the T-shaped limiting block (42) on the right side of the inner cavity of the second semicircular notch (41), the first card box (1) and the second card box (4) are fixed, and then the handle (18) is turned out from the inner cavity of the placing notch (111) and can be carried by hand;
s5, the recorder body (3) is positioned in the inner cavities of the first card box (1) and the second card box (4), when the recorder is carried out, the phenomenon of vibration can not be avoided, so the recorder body (3) can utilize the hollow rotary disc (34) to freely rotate around the outer wall of the hollow sleeve (32), and the first spring (35) and the second spring (33) which are respectively positioned above and below the hollow sleeve (32) can buffer the vibration force when the recorder body (3) vibrates up and down, in addition, the recorder body (3) can utilize the hollow rotary disc (34) to freely rotate around the outer wall of the hollow sleeve (32), and simultaneously, the two third magnet blocks (31) on the left and right sides of the front end surface of the recorder body (3) utilize the principle that the magnetic poles are the same and mutually repel each other to buffer the left and right swinging amplitude of the recorder body (3), so that the third magnet blocks (31) keep relative balance up and down in the gap between the first magnet block (25) and the second magnet block (24) which are opposite up and down, so as to prevent the wave recorder body (3) from swinging left and right too much to damage the internal circuit and influence the actual use operation.
