in the invention, a motor shell 101, a stator 102, a rotor 103 and a transmission shaft 104 are basic components of a common transmission motor, and are matched with an eccentric assembly to form a vibration motor, a heat dissipation fan blade 201 and a rear cover plate heat dissipation hole 203 play a role of dissipating heat of the motor, the local vibration motor is connected with a power supply, the rotor 103 drives the transmission shaft 104 to rotate, the transmission shaft 104 drives an eccentric vibration wheel 401 to rotate, the eccentric vibration wheel 401 is equivalent to an eccentric wheel of the common vibration motor, the eccentric vibration wheel 401 rotates and drives the transmission shaft 104 to vibrate, and then drives the motor shell 101 to vibrate, the motor shell 101 is tightly attached to the stator 102 in the common vibration motor, so that the stator 102 can vibrate severely, and further, the rotor 103 can be influenced to vibrate drastically, and the maintenance of the stator 102 and the rotor 103 is extremely unfavorable;
in the use process of the invention, if the vibration amplitude is required to be regulated, and a vibration motor of other types is not required to be replaced, when the vibration amplitude is required to be regulated, the transverse sliding block 603 is dragged to move away from the eccentric vibration wheel 401, the transverse sliding block 603 drives the sliding block 605, the sealing jacking block 606 and the rubber sealing block 607 in sequence, and moves away from the eccentric vibration wheel 401, at the moment, the rubber sealing block 607 sucks oil in the rubber expansion bag 403 into the oil supply groove 601 through the oil guide groove 602, so that the gravity difference at two sides of the eccentric vibration wheel 401 is increased, the eccentric degree is increased, namely the vibration amplitude of the vibration motor is increased, when the vibration amplitude is required to be regulated to be small, the transverse sliding block 603 is dragged to drive the sliding block 605, the sealing jacking block 606 and the rubber sealing block 607 in sequence, and moves towards the direction close to the eccentric vibration wheel 401, at the moment, the rubber sealing block 607 can squeeze the oil in the oil supply groove 601 into the rubber expansion bag 403 through the oil guide groove 602, the gravity difference at two sides of the eccentric vibrating wheel 401 is reduced, the rotating state is more stable at the moment, the effect of reducing the amplitude is realized, in order to prevent the transverse sliding block 603 from moving automatically under the action of vibrating force in the vibrating process of the vibrating motor, when the transmission shaft 104 rotates, the limit sliding block 702 is thrown towards the direction of the transverse limit groove 703 by the centrifugal force generated by the rotation of the transmission shaft 104, the limit sliding block 702 is clamped into the transverse limit groove 703, the transverse sliding block 603 cannot move transversely under the condition of insufficient transverse pushing force, if the amplitude is required to be regulated in the vibrating process of the vibrating motor, the transverse pushing force is required to be applied to the rotating transverse sliding block 603 by an external hard object, the centrifugal force of the limit sliding block 702 is overcome, the limit sliding block 702 is pushed back into the limit sliding groove 701 by the cambered surface at one side of the limit sliding block 702 close to the transverse limit groove 703, the amplitude adjustment of the vibrating motor in operation can be realized.
