The column 10 is slidably connected to the wireless network device body 1, a reset spring 11 is fixedly connected between the locking column 10 and the wireless network device body 1, a sliding groove 12 is provided on the upper side wall of the locking column 10, the sliding groove 12 is horizontally arranged along the locking column 10, an extrusion block 13 is slidably connected in the sliding groove 12, a driving plate 6 is fixedly connected to the upper end of the extrusion block 13, a deformation sheet 14 is fixedly connected in the sliding groove 12, a rotating plate 15 is provided at the upper end of the locking column 10, and the crystal head 3 and the fixed plate 5 are plugged into the network cable interface 2 together.

[0016] A guide groove 7 is provided at the side end of the fixing plate 5, and the opening of the guide groove 7 is a trumpet-shaped structure. The guide groove 7 extends to the locking head 8. When the crystal head 3 is installed, the guide groove 7 can guide the locking column 10 so that the locking column 10 moves accurately to the locking piece 8.

[0017] The side wall of the locking head 8 is an arc-shaped structure, and a locking hole 9 is provided in the middle of the locking head 8. The diameter of the locking hole 9 is the same as the diameter of the locking column 10.

The deformation sheet 14 can prevent the connecting sheet 4 from being damaged due to excessive deformation when the locking column 10 is clamped in the locking hole 9.
