Because the test device also comprises the unequal-height circuit board detection device 31, the unequal-height circuit board detection device 31 comprises a slide rail 311, a slide block 312, a second guide rail 313, a second guide sleeve 314 and a second spring 315, the unequal-height circuit board detection device 31 is arranged on the front side of the installation rod 20, the slide rail 311 is installed on the front side of the installation rod 20 in a bolt connection mode, two slide blocks 312 are connected in the slide block 312 in a sliding mode, the second guide rail 313 is installed at the lower end of the slide block 312 in a welding mode, the second guide sleeve 314 is connected on the second guide rail 313 in a sliding mode, the upper part of the outer side of the probe 21 is connected on the inner side of the second guide sleeve 314, the second spring 315 is installed on the upper side of the second guide rail 313 in a welding mode, when a user needs to detect the integrated circuit boards with different types and different heights, the user can push, the slider 312 drives the second guide rail 313 to move left and right, so as to drive the probe 21 and the contact piece 22 to move left and right, so that the contact piece 22 moves to the power interface end on the integrated circuit board of the kind, and then the user can perform detection, when the user needs to detect the integrated circuit boards of different heights, because the distance of the installation rod 20 is fixed when the installation rod 20 descends, when the installation rod 20 moves downwards, the second guide rail 313 and the second guide sleeve 314 are driven to move downwards, so as to drive the probe 21 and the contact piece 22 to move downwards, and when the installation rod 20 does not reach the maximum descending distance but the contact piece 22 is already contacted with the power interface end of the integrated circuit board, the installation rod 20 drives the second guide rail 313 to move downwards in the second guide sleeve 314 at the moment, and simultaneously compresses the second spring 315, so as to avoid the contact piece 22 from directly contacting the integrated circuit to break down, when the mounting rod 20 is moved upwards after the detection is finished, the second spring 315 is restored from the compressed state, and pushes the second guide sleeve 314 and the probe 21 to move downwards, so that the mounting rod is restored to the original position.
Because the first sliding block 312 further comprises a first screw 3121 and a first nut 3122, the first screw 3121 is installed on the upper side of the second sliding block 312 in a welding manner, the first nut 3122 is screwed onto the first screw 3121, the first nut 3122 is matched with the first screw 3121, when a user adjusts the distance between the probes 21 so as to detect different integrated circuits, the user can rotate the first nut 3122, the first nut 3122 is screwed downwards through matching with the first screw 3121, so that the first nut 3122 contacts with the upper side of the second sliding rail 311, and the second sliding block 312 is fixed at this position so as not to move any more.
