Since the position of the second shutter 62 is not changed, the position of the first stopper 44 is not changed, and the first shutter 42 still blocks the first gap 51, thereby preventing the metal rod 5 from being inserted.

As shown in fig. 7, when the metal rod 5 is inserted into the second gap 61, the metal rod 5 applies a leftward insertion pressure to the second driving inclined surface 63, and when the restoring force of the second restoring member is overcome, the second protective door 62 moves downward, so that the second protective door 62 loses the shielding effect on the second gap 61; at the same time, the pressing force of the second protective door 62 on the first stopper 44 disappears, and the first stopper 44 drives the first shutter 42 to move downward under the restoring force of the intermediate compression spring 46, so that the first shutter 42 loses the shielding effect on the first gap 51. Since the position of the first protective door 52 does not change, the position of the second stopper 45 does not change, and the second stopper 43 still functions to block the second gap 61, thereby preventing the metal rod 5 from being inserted further.
