(94) internal to be equipped with No. two electrical contacts (92), two extra shells (94) are fixed on little spring (96) one end, and little spring (96) is another
End is fixed on elevating mechanism shell (13) inner wall below host housing (12), and two extra shells (94) and No.1 shell (93) exist
On same vertical line；The sealing ring (95) is fixed on two extra shell (94) open-ended places, when No.1 shell (93) and No. two
Shell (94) merges, and sealing ring (95) is sealed, if generating electric arc between electrical contact will not disorderly splash；When motor normal operation,
Two elevating mechanisms (4) are stretched outward, and No.1 shell (93) is contacted with two extra shells (94) at this time, No.1 electrical contact (91) with
No. two electrical contact (92) contacts, form access, and motor starts turning, as motor temperature exception, two elevating mechanism (4) Xiang Zhongxin
It shrinks, elevating lever (43), which drives No.1 shell (93) to move up, at this time separates it with two extra shells (94), motor power-off.
