Lifting device |
| abstract |
A lifting device includes a base body. The the base body includes a supporting surface and defines a cavity. The cavity extends through the supporting surface. The lifting device further includes a magnetic bar, a spring, and a coil in the cavity. The spring includes a first end fixed to an end of the magnetic bar away from the supporting surface and a second end fixed on a wall of the cavity. The coil surrounds the magnetic bar. When the coil is applied with a voltage to generate an electromagnetic induction, the magnetic bar is driven to move out of the cavity from the supporting surface or move to compress the spring. |
