[0047] When the present scheme is used:

[0048] S1, the operator releases the buckle locking of the buckle locking pin 112 and the buckle locking groove 123, then manually turns over and opens the turnover operation panel 114, the turnover operation panel 114 is connected through the rotation of the symmetrical shaft mounting seat 117 and the shaft connecting piece 116, the operator turns over the turnover operation panel 114 to the vertical state, at this time the turnover cover completely separates from the limiting of the box body locking slot 103.
