During installation, the cables are extruded to move the clamping plates 13 along the dovetail grooves 15, and the tension spring 14 extends, so that the cables are clamped. Then, the second upper housing 4 and the second lower housing 2 are fixed by the fixing component. At the same time, when the first upper housing 5 and the first lower housing 1 are connected, the fixing plates 11 and the clamping plates 13 are in contact, further restricting the position of the clamping plates 13.
