Described line outlet place is all provided with locking device.The test wire stretched out outside insulation crust that is arranged so that of locking device is fixed preferably, and structure is simple, and it is comparatively convenient to use.
In described insulation crust, corresponding line outlet side is provided with cylindrical locating shaft, and each locating shaft lay respectively at each test wire and lead on the path of each line outlet.The setting of each locating shaft can reduce the flexible resistance of each test wire and locate the expansion rail of each test wire.
Described axis is fixed on insulation crust by end cap, and is provided with bearing between described axis and described wire spool.Stabilized structure, bearing can support the rotation between wire spool and axis.
The top of described insulation crust is provided with a handle.Handle be arranged so that this device is able to be convenient for carrying.
The beneficial effect that the utility model brings is:
1. stretch out the equal automatically retractable in test wire two ends outside insulation crust, use more convenient;
2. the setting of locking device can realize the fixing of test wire rapidly;
3. the setting of locating shaft can reduce the flexible resistance of test wire and the expansion rail of location test line;
4. stabilized structure, is convenient for carrying.
