In the present embodiment, the clamping mechanism has a telescopic function by providing the guide bar 34 between one clamping plate and the wire base 10 and allowing the clamping plate to move relative to the wire base 10 under the restriction of the guide bar 34.
In practical application, as shown in fig. 2, fig. 2 is a quick wiring auxiliary device for a mechanical property test of a circuit breaker in an unfolding state of a clamping mechanism, wherein the clamping mechanism is used for clamping a terminal strip, two wall grooves and guide rods 34 are respectively arranged at two ends of a side wall of a wiring base 10, the depth of each wall groove is at least greater than or equal to the length of each guide rod 34, meanwhile, when a spring is in a natural state or a compressed state, each guide rod 34 completely enters the corresponding wall groove and enables a clamping plate to be attached to the wiring base 10, and when the spring is in an unfolding state, each guide rod 34 penetrates through the corresponding wall groove and is exposed, so that the clamping plate is separated from the wiring base 10, and therefore, the clamping mechanism is telescopic, and the telescopic distance can be automatically adjusted according to the sizes of the terminal strips, so that the terminal strips with different sizes are adaptively adjusted.
The fixing manner of the guide rod 34 may be to lock the position of the guide rod 34 by using a locking block or fix the guide rod 34 by using the rebound effect of a spring, which is not limited herein.
In another example, a more flexible telescopic movement can be achieved by both clamping plates being movable relative to the wire base 10.
In one possible way, for more reliable clamping, the inner side wall of the clamping plate is provided with an anti-slip silica gel pad 33, so that the contact area between the auxiliary device and the terminal strip is increased, and reliable fixing is ensured. Meanwhile, the cross section structure of the clamping plate is of an L-shaped structure, so that the clamping plate can be firmly buckled at the edge of the terminal strip.
