As shown in fig. 3, in the detection process, the push-pull electromagnet 13 is controlled to act outside the vehicle, the push-pull electromagnet 13 drives the bayonet 12 to exit from the pin hole of the inner sleeve 7, so that the elastic force of the first spring 6 can be released, the inner sleeve 7 slides forwards, the outer sleeve 5 slides backwards, the inner sleeve 7 pushes the slider 8 to slide forwards, and the inner sleeve 7 pushes the push rod 2 to slide backwards. By properly setting the lengths of the outer sleeve 5 and the inner sleeve 7, the two are kept in registration without separation. After the test is finished, the pin holes of the outer sleeve 5 and the inner sleeve 7 can be clamped by pressing the push plate 17 and the push rod 2 back to the initial position (reset) and using the clamping pins 12 again.
In another preferred embodiment, as shown in fig. 2 and 3, the outer sleeve 5 is located at the rear side of the inner sleeve 7, the outer sleeve 5 has a front end open cylindrical structure, the inner sleeve 7 has a rear end open cylindrical structure, and the front housing 10 is provided with slide ways 9 corresponding to the outer sleeve 5 and the inner sleeve 7, respectively.
