During the rotation of the turntable 8, the connecting belt 7 is pulled as a whole. During the pulling of the connecting belt 7, the pushing plate 51 is pulled, so that the positioning pin 5 is pulled out of the positioning hole 171. At the same time, the connecting belt 7 is compressed as a whole during the pulling of the pushing plate 51. At this time, the protective shell 10 can be removed as a whole, and the protruding rod 9 is released. Under the action of the compressed connecting belt 7, the positioning pin 5 is withdrawn as a whole.
