Specifically, the inner side wall of the groove 8 is connected to one side of the triangular sliding block 12 through a first spring 14; the first spring 14 is used for pushing the triangular slide block 12 to move in a resetting way. The inner side of the conical guard plate 7 is connected with a movable plate 19 through a second spring 18, and the number of the second springs 18 is not less than four; the second springs 18 may provide a cushion support for the tapered guard 7. A first thread 22 and a second thread 23 are respectively arranged on two sides of the double-threaded rod 21, the first thread 22 is in threaded connection with the inner side of a first internal thread sleeve 24, the second thread 23 is in threaded connection with the inner side of a second internal thread sleeve 25, and the thread directions of the first thread 22 and the second thread 23 are opposite to each other; so that the first and second internally threaded

sleeves

24 and 25 are moved in opposite directions by the first and

second threads

22 and 23, respectively, when the double threaded rod 21 is rotated. One side of the double threaded rod 21 penetrates through the door body 1 and is fixedly connected with a first gear 29, the back of the door body 1 is rotatably connected with a second gear 30, the second gear 30 is connected with the first gear 29 through a chain 13, and one side of the second gear 30 is fixedly provided with a hand wheel 31; the hand wheel 31 facilitates the rotation of the second gear 30 to drive the first gear 29 to rotate, and the first gear 29 drives the double-threaded rod 21 to rotate.
