It should be understood that the active probe includes a body and two probes connected to the body by wires, and in a conventional use case, an operator needs to hold one probe with both hands and then test, so that a single person can only grasp a set of signals at a time, and test points in a small space cannot be tested due to the limitation of the size of the operator's hands.

In order to improve the above, the present utility model provides an auxiliary clamping device, which comprises at least two interconnected arms 1, wherein the number of the arms 1 can be two, four or more, and the number of the arms 1 is two.

Because the two support arms 1 of the auxiliary clamping device have smaller volumes, the auxiliary clamping device for fixing the active probe can be stretched into a plurality of narrower spaces to carry out auxiliary test on the active probe. During testing, an operator can operate the distance between the two probes by adjusting the positions of the free ends of the two support arms 1, for example, pressing the two support arms 1 to enable the free ends of the two support arms 1 to be close to each other, namely, the two first mounting parts 2 to be close to each other, so that the distance between the two probes is shortened; the free ends of one arm 1 are rotated away from the free ends of the other arm 1 such that the free ends of the two arms 1 are away from each other, i.e. the two first mounting portions 2 are away from each other, thereby increasing the distance between the two probes.

According to the auxiliary clamping device, an operator can control two probes by only one hand, the distance between the two probes is adjusted to perform single-ended signal testing, the using convenience of the active probe is improved, and as the auxiliary clamping device is far smaller than fingers of a person, the traditional active probe only needs two hands to test one group of signals and can not go deep into pain points of a test position with a small space, so that the testing efficiency is greatly improved, the labor cost is saved, the testing precision and reliability are improved, and the application range of the active probe is widened.
