[0026] Specifically, the end of slide rod 64 away from first connecting plate 65 is fixedly connected with second connecting plate 66, and slide rod 64 is arranged inside mounting plate 63.

[0027] In this embodiment: by setting first connecting plate 65 and second connecting plate 66, the slide rod 64 can be limited, which reduces the possibility that the slide rod 64 easily comes off the inside of the soft frame 61 during use of the equipment, causing the equipment to be difficult to position.

[0028] Specifically, the surface of slide rod 64 is sleeved with first spring 67, and slide rod 64 is arranged to facilitate the positioning and guidance of first spring 67.

[0029] Specifically, one end of first spring 67 is fixedly connected to the surface of second connecting plate 66, and the end of first spring 67 away from second connecting plate 66 is fixedly connected to the surface of soft frame 61, and first spring 67 is arranged to facilitate the application of reset spring force to slide rod 64.
