At the avoiding position, the first shutter 410 and the second shutter 420 can avoid the avoiding space for the movement of the lower probe mechanism 300 below, so that the movement of the lower probe mechanism 300 is not hindered. For example, the first shutter 410 and the second shutter 420 are moved to the end side on the left side, so that the right side can form an avoiding space for the movement of the protruding part on the right side of the lower probe mechanism 300, and the protruding part on the left side of the lower probe mechanism 300 can penetrate the first shutter 410 and the second shutter 420; or, the first shutter 410 and the second shutter 420 are moved to the end side on the right side, so that the left side can form an avoiding space for the movement of the protruding part on the left side of the lower probe mechanism 300, and the protruding part on the right side of the lower probe mechanism 300 can penetrate the first shutter 410 and the second shutter 420.
