At this time, the spring 88 can be set in a compressed state. By limiting the spring 88 by the telescopic groove 8131, the stability of the extension and contraction of the spring 88 can be improved.

[0108] It should be noted that, in some other embodiments, the spring 88 can be directly arranged in the accommodating groove 813, and one end of the spring 88 can directly abut against the bottom wall of the accommodating groove 813. When the baffle 86 abuts against the protective cover 83, the protective cover 83 can abut against one end of the spring 88 and compress the spring 88.

[0109] In some embodiments, when the blocking bar 86 is separated from the protective cover 83, the spring 88 can drive the protective cover 83 to extend out of the receiving groove 813, and then when the protective cover 83 is removed, the spring 88 can automatically pop out the protective cover 83, thereby improving the removal efficiency of the protective cover 83.
