In addition, in the embodiment, the shape of the key 1 is triangular, and accordingly, the key hole 31 is also triangular. The external dimension of the key hole 31 is slightly larger than that of the key 1, so that the key 1 can move in the depth direction in the key hole 31, and meanwhile, displacement in other directions cannot be generated. For example, when there is only one bayonet joint on the key 1, the triangular key 1 and the key hole 31 can ensure that the key 1 cannot rotate around the bayonet joint. Of course, the key 1 may be configured in other non-circular shapes, and it is also ensured that the key 1 does not rotate around the latch. In addition, when the key 1 is provided with two snap joints, the key 1 will not rotate under the restriction of the two snap joints and the snap holes, so the key 1 and the key hole 31 can be set to be circular.

In addition, a sealing plate 8 is further arranged at one end of the casing 6, and after the key 1 and the limit ring 3 are assembled, the sealing plate 8 is fixedly connected with the component support 7 and the casing 6 to fix the limit ring 3 on the casing 6 and further fix the key 1.
