Preferably, described frame includes being arranged on holding frame both ends and the support being connected with holding frame rotary moveable
Plate；Described supporting plate is provided with the elongate holes vertically extended, and described position-limited rack passes through elongate holes and support
Plate connects.Position-limited rack can be along adjustment position above and below elongate holes, so as to adjust the distance between position-limited rack and holding frame, with this
To adapt to the power line of different length.
Preferably, also include the balancing weight for the pulling force of dummy activity on the power line.When carrying out cripping test,
The one end of wire away from plug is knotted, and balancing weight is suspended at knotting；When plug rotates with holding frame, wire due to by
To the Action of Gravity Field of balancing weight, a larger active force can be produced in the junction of wire and plug, is come with this more real
The bending action of power line when simulating use.
Preferably, described drive device is motor, described motor is connected by shaft coupling with holding frame.Motor
Feeding is accurate, and can preferably control and rotate and reverse.
Preferably, described position-limited rack includes two gag lever posts be arrangeding in parallel, if being arranged with described gag lever post
Dry sleeve；Corresponded between sleeve on two gag lever posts, and sleeve corresponding to each two forms position-limiting unit；Corresponding set
Lead channels are formed between cylinder.Wire knots through lead channels and in one end away from plug, when holding frame drives plug to turn
When dynamic, the bearing of trend of wire is limited frame and limited, and can not be swung with the rotation of plug, it is achieved thereby that plug and power supply
Bending between line.
