When the second adjusting slider 322 moves to the straight groove entrance at the other end of the irregular groove 321, the second adjusting slider 322 is released. At this time, under the action of the restoring force of the spring 314, the spring 314 drives the second adjusting slider 313 and the second adjusting slider 322 to move away from the contact 1, thereby causing the second adjusting slider 322 to enter the straight groove of the irregular groove 321, thus completing the locking of the second adjusting slider 322, thereby realizing the locking of the test position.
