Structure, by setting insulated handle, is prevented from contact accident occur, preferably to protect the safety of operating personnel, simultaneous retractable
The handle of structure, adjustable length, can it is more specific the need for regulation handle length, to adapt to the requirement of different operating environment,
Simultaneously longer insulated handle can further reduce the risk that operating personnel occurs electric shock accidents.
Below in conjunction with the accompanying drawings 1 and Fig. 2 come illustrate the present invention offer phase sequence testing auxiliary device use principle：
With a hand-held phase sequence indicator when using, the phase sequence testing auxiliary device contact of the hand-held the application of another hand is surveyed
The second probe is stirred in examination body, position and distance according to the jack on test body, and the first slide bar slides along the direction of opening
Dynamic, now the outer tooth bar on the first slide bar is engaged with the circle internal tooth being fixed on the bearing of open center, while on bearing
Internal tooth is engaged with the outer tooth bar on the second slide bar, and then drives the second slide bar similarly to be slided along the length direction of opening, and
Because the first slide bar and the second slide bar are the axis centres on the bearing symmetrical therefore, the first slide bar and the second slide bar it
Between be that synchronous backward is slided, i.e. the first slide bar and the second slide bar are slided simultaneously towards bearing, or simultaneously to away from bearing
Direction slide, the second probe and the 3rd probe are dialed to suitable position by the distance between jack according to test body, will
First probe, the second probe and the 3rd probe are inserted in corresponding jack, and then test body is tested
In sum, the present invention provide phase sequence testing auxiliary device, including the first probe, the probe of the second probe the 3rd,
Base and the handle being connected with the base, are provided with accommodating chamber in the base, a side wall of the base is provided with and institute
The opening of the strip of accommodating chamber connection is stated, first probe is fixed on the middle part of the opening, second probe and the
Three probes are symmetrically set in the both sides of first probe, and second probe and the 3rd probe can be synchronous anti-along the opening
To slip.Testing needle when phase sequence testing auxiliary device in the application changes original testing line head into pluggable, is then attached to
In adjustable and portable operation handle, middle one is maintained static, and other both sides are mutually fixed on adjustable base, thus can basis
The shape of on-the-spot test carrier, so when coordinating with other jacks, simpler easily can insert a probe into jack,
Simple to operate, therefore, it is possible to the various sockets of correspondence, applicable scope is wider, can be preferably powered aobvious by meter and switch board
Show that device is connected, it can be ensured that the accuracy and reliability of nuclear phase, at the same can also by adjust the second probe and the 3rd probe with
The distance between first probe, to match the switch board electrification display socket of different model, after distance adjustment, a hand-held phase
