The upper and lower housings are fixedly connected by an elastic telescopic connecting member 71, as shown in fig. 6 and 7, the connecting member 71 includes an upper connecting member 712 and a lower connecting member 711, the top of the upper connecting member 712 is fixedly connected with the upper housing 2, the lower connecting member 711 is fixedly connected with the lower housing 1, the upper connecting member 712 is elastically and fixedly connected with the lower connecting member 711 by a return spring 715, that is, one end of the return spring 715 is fixed on the bottom surface of the upper connecting member 712, the other end is fixed on the top surface of the lower connecting member 711, and the return spring 715 is used for elastically supporting and connecting the upper and lower connecting members, so that the upper and lower connecting members can elastically stretch out. The structure of the upper and lower connecting pieces can be determined according to the concrete structure of the upper and lower inner shells and the upper and lower outer shells, for example, the upper and lower connecting pieces can be fixedly connected with the upper and lower inner shells or fixedly connected with the upper and lower outer shells in various fixing modes.

As shown in fig. 6 to 10, the upper connecting part 712 has a cavity opening downwards, and specifically, the upper connecting part 712 is a frame structure with an opening at the lower side, and includes five side faces connected to each other, one face of which is open, and the opening end of which is downward. The top of the lower connecting piece 711 and the return spring 715 are nested in the cavity, and the lower connecting piece 711 is slightly smaller than the volume of the cavity, so that the lower connecting piece 711 and the return spring 715 can move up and down in the cavity under the action of external force, but cannot move back and forth or left and right transversely, so as to ensure that the upper and lower shells cannot be dislocated.

In order to prevent the lower connecting member 711 from being separated from the cavity, so that the return spring 715 is exposed out of the cavity, and may clamp clothes being ironed, a limiting structure for preventing the lower connecting member from being separated from the cavity is further provided on the connection 71. As shown in fig. 7, in the embodiment provided by the present invention, the lower connecting member 711 is substantially T-shaped, the upper structure of the T-shape is nested in the cavity, the side walls of the two opposite sides of the upper connecting member 712 are respectively fixed with substantially L-shaped limit stops 713, one end of each limit stop 713 is fixed on the side wall of the upper connecting member 712, the other end of each limit stop 713 is bent transversely towards the open end of the cavity to partially close the open end of the cavity, and the lower structure of the T-shape is fixed on the lower housing 1 after penetrating out of the gap between the two transversely bent limit stops 713. Or as shown in fig. 8, bottom stoppers 714 capable of partially closing the open end are disposed at two opposite sides of the open end of the cavity, and the T-shaped lower structure of the lower connector 711 is inserted into the gap between the two bottom stoppers 714 and fixed on the lower housing 1. The limit stop 713 and the bottom stop 714 prevent the lower connector 711 from being removed from the cavity.
