Portion's shell；Through slot compatible with connecting terminal upper end is arranged in the lower end of the fixing seat, constitutes clamping connecting terminal with briquetting
The clamping device on top；Four stepped holes are uniformly arranged in the upper body；The lower case and upper body constitute shell
Body group；The upper end of the shell group is uniformly arranged four stepped holes extended downwardly；The diameter big end of the stepped hole is downward；Institute
The multi-diameter shaft that setting is adapted to it in stepped hole is stated, shell group upper end and connection one handle are stretched out in the upper end of the multi-diameter shaft；Institute
It states and is set with reset spring in the middle part of multi-diameter shaft；Two sides in the shell group, adjacent with power cord ends are respectively set and the side
The blind hole of multi-diameter shaft lower end connection.
Preferably, the handle is connect with multi-diameter shaft using bolt.
Preferably, the fixing seat is connect by bolt with lower case.
Preferably, the lower case is connect by bolt with upper body.
Preferably, the handle uses rod handle.
Compared with prior art, the utility model has the advantages that
The utility model can be fixed on the corresponding position of connecting terminal easily and fast, and when use fixes this isolating device
Needing to dismantle near secondary terminals, then by the secondary terminals dismantled conveniently, safely, be stably fixed to isolating device
It is interior, it touch staff can not directly, prevented the risk of personal electric shock and alternating current-direct current string electricity.
