Bar portion threaded engagement.According to the relation of active force and reaction force, the First terrace 211 in the second mounting hole 23 also can be to spiral shell
Nail produces side force F4'=F1' cos α=F1Cos α=Fsin α cos α (F in figure1'=F1), screw is in side force F4' effect
Under, so increase screw with the frictional force of nut 400 (because the screw thread of the screw portion of screw is matched somebody with somebody in the screw thread with nut 400
Gap is had unavoidably during conjunction, in F4' in the presence of screw have clockwise rotating tendency, such screw is mutually screwed with nut 400
This half of screw screw thread closer, therefore increase screw and the nut 400 that can coordinate by rotation with the screw thread of nut 400
Frictional force), so as to consume the axial force F of screw, be conducive to further reducing the deformation of fixed frame 1.
On the other hand, as shown in figure 5, the utility model embodiment additionally provides a kind of switch on wall or wall socket, bag
