## Abstract

A transfer machine includes: a main body assembly, including two lifting rods capable of moving up and down, two seat plates corresponding to the two lifting rods, wherein the seat plates are capable of rotating around the corresponding lifting rods, allowing the seat plates to close with or separate from each other; a lifting assembly, including a base, a connecting rod fixedly connected to the lifting rods and an electronic controlling assembly. The base includes a guiding bar extending vertically, the lifting rods can move along the guiding bar; the electronic controlling assembly includes a pushing rod, fixedly connected to the connecting rod to drive the two lifting rods to move to further drive the main body assembly to move. The connecting rod has a first connection portion and a second connection portion, a foot section is formed between the first connection portion and the second connection portion.
