[0042] The auxiliary component 210 includes a force-bearing frame 2101 arranged outside the support frame 201, and the outer wall of the force-bearing frame 2101 on the side away from the support frame 201 is fixedly connected to a second flexible plate 2102, and the inner wall of the support frame 201 is rotatably connected to a flip frame 2106 through a rotating shaft. There are two flip frames 2106, and the two flip frames 2106 are symmetrically arranged around the central axis of the force-bearing plate, and the outer wall of the flip frame 2106 on the side away from the support frame 201 is fixedly connected to a third flexible plate 2107.

[0043] One end of the force-bearing frame 2101 away from the second flexible plate 2102 is fixedly connected to the third fixed axis 2103, one end of the third fixed axis 2103 away from the force-bearing frame 2101 passes through the support frame 201 and is fixedly connected to a limiting plate 2104, and an outer wall of the limiting plate 2104 close to the force-bearing frame 2101 is fixedly connected to a third spring 2105, the second spring 206 is used for resetting the force-bearing frame 2101, and one end of the third spring 2105 away from the limiting plate 2104 is fixedly connected to the support frame 201.

[0044] The inner wall of the limiting plate 2104 is rotatably connected to the second rotating rod 2109 through a rotating shaft, the inner wall of the second rotating rod 2109 is rotatably connected to the adjusting block 21010 through a rotating shaft, the inner wall of the adjusting block 21010 is slidably connected to the first fixed shaft 205, the bottom of the adjusting block 21010 is fixedly connected to the second spring 206, the inner wall of the second rotating rod 2109 on the side away from the adjusting block 21010 is rotatably connected to the first rotating rod 2108, the end of the first rotating rod 2108 away from the second rotating rod 2109 is rotatably connected to the flip frame 2106, when the adjusting block 21010 slides downward, the adjusting block 21010 flips the flip frame 2106 through the first rotating rod 2108.
