The side walls of the outer sleeve 5 and the inner sleeve 7 are respectively provided with a pin hole, and the two pin holes are aligned after the first spring 6 is compressed and are inserted into the bayonet 12 for locking. A push-pull electromagnet 13 is fixedly mounted on the front housing 10 and is connected with the bayonet 12 for controlling the bayonet 12 to enter or exit the pin hole of the inner sleeve 7.
As shown in fig. 2, the first spring 6 of the present embodiment is previously compressed between the outer sleeve 5 and the inner sleeve 7, and inserted into the pin holes of the outer sleeve 5 and the inner sleeve 7 with the bayonet pins 12 to lock both. As shown in fig. 3, in the detection process, by controlling the push-pull electromagnet 13 to act outside the vehicle, the push-pull electromagnet 13 drives the bayonet lock 12 to withdraw 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 forward, the outer sleeve 5 slides backward, and the inner sleeve 7 pushes the sliding block 8 to slide forward, and the inner sleeve 7 pushes the push rod 2 to slide backward.
