The pulling and inserting of the transverse supporting rod can be easily realized, and the phenomenon of shaking caused by loose matching between the transverse supporting rod and the shell can be avoided. The concrete vibration reduction process of the technical scheme is as follows: when the vibration reduction spring contracts due to vibration, the vibration reduction spring drives the piston rod to drive the first piston to move so that the first oil cavity is reduced, the first oil cavity is reduced to drive oil in the damping oil cylinder to flow from the first oil cavity to the second oil cavity through the window, the door plate is pushed open so that the door plate does not generate damping action on the oil when the oil flows through the window, the electromagnetic force attraction mechanism loses the fixing action on the first piston and the second piston so that the second piston can freely move relative to the first piston, and therefore the damping action is small, the vibration reduction spring cannot contract and be blocked, namely the spring can contract in time to reduce the contraction stroke bump of the spring, and the door plate is blocked in the window again under the action of the door plate resetting mechanism after the contraction stroke of the spring is finished. And then the spring extends and resets to release energy, the cylinder body of the damping oil cylinder and the first piston generate separation motion as a result of the extension to enable the second oil cavity to be reduced and the first oil cavity to be enlarged, so that the oil in the damping oil cylinder flows from the second oil cavity to the first oil cavity through the window, at the moment, the first piston and the second piston are fixed by the electromagnetic force suction mechanism to keep the relative positions unchanged, the door plate cannot be pushed open, the oil can pass through the main damping channel in the whole spring contraction stroke to generate friction damping energy dissipation, and the spring extension stroke bump is reduced.

When vibration generated by the mobile phone (for example, when the mobile phone prompts a message in a vibration mode or generates vibration when a call is received) is transmitted through the transverse support rod, the resistance increasing block is forced to deform, the deformation of the resistance increasing block causes the elastic diaphragm to deform and reset towards the vacant cavity, and meanwhile, the quicksand flows back and forth between the first filling cavity and the second filling cavity, the quicksand rubs with each other when flowing to consume vibration energy, the quicksand rubs with the friction hole when flowing through the friction hole and the friction between the quicksand is intensified, so that the vibration absorption effect is more remarkable, the vibration is prevented from being transmitted to the shell, and the vibration is transmitted to the shell, so that the electric parts in the shell and the electric connection between the plug and the first power socket are prone to poor in contact.

The door panel 942 is only capable of opening unidirectionally toward the second oil chamber 916. A speed sensor 96 is provided in the communication hole 941. Door panel 942 is provided with a plurality of primary damping channels 9422 extending therethrough. A damping rod 9423 extends through main damping channel 9422.

Referring to fig. 8, 9 and 10, in use, the first and

second oil chambers

915, 916 are filled with a liquid such as oil. When the damping spring 92 contracts due to impact, the damping spring 92 drives the piston rod 913 to drive the first piston 912 to move so as to reduce the first oil chamber 915, the first oil chamber 915 reduces the driving oil to flow from the first oil chamber 915 to the second oil chamber 916 through the communication hole 941, the flow direction of the oil is detected by the speed sensor 96, the speed sensor 96 controls the electromagnet 951 to lose electricity through the control system, so that the electromagnetic force attraction mechanism 95 loses the fixing function on the first piston 912 and the second piston 914 (namely, the first piston 912 and the second piston 914 can move relatively), when the oil flows through the communication hole 941, the door plate 942 is pushed open so that the oil flows through the communication hole 941 to enter the second oil chamber 916 (namely, the door plate 942 does not generate damping function on the oil), so that the damping function is small and the damping spring cannot be blocked, namely, the spring can contract in time to reduce the contraction stroke of the spring, after the spring retracting stroke is completed, the door leaf 942 is stopped again in the communicating hole 941 by automatically rotating and closing under the action of the door leaf returning mechanism 97 (i.e. because the door leaf keeps inclining downwards and has density higher than that of oil). Then the damping spring 92 extends and resets to release energy, the damping cylinder body 911 and the first piston 912 are separated as a result of the extension to enable the second oil chamber 916 to shrink and the first oil chamber 915 to enlarge, so that oil flows from the second oil chamber 916 to the first oil chamber 915 through the communication hole 941, the flow direction of the oil is detected by the speed sensor 96, the speed sensor 96 controls the electromagnet 951 to be electrified through the control system, the electromagnet 951 generates magnetic force to enable the electromagnetic force suction mechanism 95 to fix and press the first piston 912 and the second piston 914 on the oil, the door plate 942 cannot be pushed open when the oil flows in the direction, the oil can generate a friction damping phenomenon in the whole spring contraction stroke to absorb energy, and the spring extension stroke bump is reduced.

The damping energy-absorbing vibration-damping process of the door plate is as follows: the oil flows through the main damping channel, the branch damping channel and the damping rod, and the vibration energy is converted into heat energy to be consumed. If the vibration is small and not enough to cause the deformation of the blind hole, only the oil shakes, and the damping rod shakes to absorb energy when the oil shakes.

Referring to fig. 11, the nut 8 includes a body section 811, a wobble stop section 812 and a thread alignment retaining mechanism 82.
