Lifting device and vibration plate

A lifting device, comprising:

• a mounting base, a lifting assembly, a transmission assembly, a driving assembly, and a lifting base, wherein
• the lifting assembly is mounted on the mounting base, and the lifting assembly comprises two rocker lifting mechanisms arranged oppositely;
• the transmission assembly is located between the two rocker lifting mechanisms;
• the transmission assembly comprises an eccentric part, a first connecting rod, and a second connecting rod;
• two ends of the first connecting rod are respectively hinged to the two rocker lifting mechanisms;
• one end of the second connecting rod is connected to the eccentric part, and the other end of the second connecting rod is hinged to one of the two rocker lifting mechanisms;
• the driving assembly is connected to the eccentric part;
• the lifting base is connected to the lifting assembly on the side away from the mounting base;
• the driving assembly drives the eccentric part to rotate;
• and the eccentric part drives and the lifting assembly to rise and fall through the transmission assembly, so that the lifting assembly drives the lifting base to rise and fall relative to the mounting base.
