When the end portion of the third connecting member 330 elastically abutting against the second annular plate 240 is the bending portion 350, the contact between the third connecting member 330 and the second annular plate 240 is more reliable, so as to reduce the risk of the end portion of the third connecting member 330 falling off from the surface of the second annular plate 240, and when the end portion of the third connecting member 330 elastically abutting against the first circuit board 110 is the bending portion 350, the clamping stability of the first buckle 150 and the first limiting portion 160 on the third connecting member 330 is increased, so as to increase the connection stability of the third connecting member 330 and the first circuit board 110.

When the end portion of the fourth connecting member 340 elastically abutting against the second annular plate 240 is the bending portion 350, the contact between the fourth connecting member 340 and the second annular plate 240 can be more reliable, so as to reduce the risk of the end portion of the fourth connecting member 340 falling off from the surface of the second annular plate 240, and when the end portion of the fourth connecting member 340 elastically abutting against the second circuit board 210 is the bending portion 350, the clamping stability of the second buckle 250 and the second limiting portion 260 to the fourth connecting member 340 can be increased, so as to increase the connection stability of the fourth connecting member 340 and the second circuit board 210.
